Really excellent job! Great to see this method with the microspheres taken to what I think is probably its full potential, and in a way that's totally doable outside of a lab. It's also very impressive to achieve sub ambient temps without any sort of film or insulation. It must be radiating a fair amount of w/m^2 to overcome the breeze blowing over it. Very well done, and it was especially useful to include info about bulk suppliers. I'm still working on new methods myself. I'll be thrilled if I can hit similar numbers as you have.
@@TechIngredients So how about the polar opposite now, a paint that absorbs as much heat radiation as possible. Could be interesting for a purely convection based heat pump. Would be slow, but cheap to run 😉
@@DerSolinski that's exactly what I was thinking. Then I could have two separate roof panels to climate control my chicken coop year round with no power.
@@DerSolinski You're mentioning two different methods of heat transfer here. If you're absorbing solar radiation you want a solar heater (I think they already did a video on that). If you're looking for an air cooled convection based system you have a different heat transfer coefficient related to how efficient the surface of a radiator is at exchanging heat with moving air. It's a different problem, but still interesting.
Just pre-emptively expressing here: Please do not change the format of your channel. It is perfect the way it is. It's so nice to listen to you without background music and overcommercialization or overproduction. You can see this creeping in old Mythbusters episodes and by the end of 8 seasons, the show was unrecognizeable. Tech Ingredients cannot be perfected anymore, it is epitome of high quality, small business vibe production. Thank you for everything you do.
Good call. The format is bang on. I also appreciate how accessible they make most things. For example explaining an affordable solution to make a mixer into a heated mixer. Even though he had the relevant equipment and you can purchase the equipment from the same place as the parts he suggested as an alternative, affordable solution. If only my teachers were half as good as what Tech Ingredients produces. A prime example of best use of social media and what it can offer.
I wholeheartedly agree with this comment. As an aside, I felt that the B roll footage when they left their home workshop to go to the warehouse was rather funny. I don't seem to remember them using b roll like that before.
This was always the dream of the web: to freely share ideas, innovate, and communicate. I have so much respect for the quality of your content, the production quality, the writing, the delivery, it's all fantastic, but the part that really blows me away is the commitment to getting the information out to the world, without putting it behind a pay wall or patent. You are truly working to improve the world, not just your own experience in it.
This is rare on UA-cam to come to this point of measurable and traceable developments with absolutely no other motive than sharing it with everyone. This is so inspiring and gives me hope in humanity. A few more of these guys and we d make so many more discoveries. Sure some researchers probably did this and published it, but this guy here brings it to the masses. Love this channel, pure gold
I love living in the modern age. So much information is so freely given by people who I would NEVER have the luxury of meeting in real life, let alone enough time for them to teach me all of the amazing information they have in their heads. The only way to learn about stuff like this in such an in-depth way would be spending thousands of dollars going to college. I tip my hat to you sir, and your amazing knowledge. Thanks for sharing everything so freely, yet in a way thats so easy to understand.
Bravo, and I second that most emphatically! If I wasn't subsisting on temporary disability insurance, I'd find a way to pay for your next several rounds of beers. Best I can do today is a smaller amount in your "coffee fund". Cheers! 🍻
In Aerospace, when we solvent clean aluminum, the technique is to wipe the solvent on with a fully saturated cloth, wetting the entire surface, and then wipe it off with a clean cloth before it can evaporate. Then repeat as necessary. That prevents the oils and dirt from redepositing as the solvent evaporates.
I had my shed painted with one of those products in Australia and before in the summer you couldn’t work in that shed and now it’s cooler in the shed than outside I was hugely impressed and highly recommend it.
There's only two kinds of sciences which are fun: applied and theoretical - everything in-between sits out of context of anything that seems relevant and therefore will bore the shit out of you.
@@ObservingLibertarian Ok, but that's not really what they're commenting on. Not all applied science has a meaningful DIY component, which is a large basis of this channel's content. That's what OP is talking about, not whether there's anything beyond applied or theoretical science.
I absolutely love the mildly comedic flavor of this episode. Science focused channels have a tendency to be a bit “robotic”, but your personality is one of a kind. Thank you for all of the amazing videos!
I completely disagree. I found the comedic elements are off-putting. They don't fit with the genre of the video. By its nature, the comedic content has to be somewhat fictionalized, and so its inclusion in what is otherwise a truthful instructional video makes it hard to take the rest of the video seriously.
@@rorypenstock1763 They kept the comedic parts limited to "how do we make watching paint dry interesting?" so it really doesn't detract from the episode at all. Adding balls jokes made it memorable. Completely disagree with you disagreeing Rory.
yes sir ....your content was always perfect and very understandeble. Now even better because you and your sons mix in a little bit more humor every day. You are one of the very few "serious" science channels on youtube that figed this out , just like Sabine Hossenfelder. It used to be old knowledge that people , if they are not already a specialist in the field your speech or demo is gonna be about....can only give you full attention for 15 minutes. Then you need a gentle reset with some humor and/or acting. You are doing that perfect.
As someone who painted cars professionally, I always made a swatch (usually sheet metal because that's what cars are made of )and prepped/painted it at the same time and in the same manner as the vehicle I was painting. I would then use that to test whether or not the paint on the vehicle itself was ready for another coat or the next process and wouldn't have to touch the vehicle. I would also keep these swatches, in addition to photos of the vehicle in what was my portfolio.
Can we appreciate this guy trying to both teach and show us how to solve real problems at home? Keep it up! Definitely watching more content from you and subbed!
I really like this guy. He's freaking hardcore! Tells you where to source the stuff. Make your own world's shiniest paint. Drills down into the details of why he's doing each particular step. I especially liked that part, that information is useful for whenever I paint anything not just this thing. Consider this shared.
@@TheAlbrowniv There are many contenders for greatest UA-cam channel, and this one certainly would be in the top bunch for science related.. Also a big, BIG point in his favour, this guy is straight, and honest with integrity. You get NO payments from the big boys to promote anything here! He shares knowledge. More than that he shares his own discoveries. A great thing. Really a great thing.
Love the sublime comedic homage to Walter White (with all the sniffing and masks). Humour apart, the wealth of knowledge, imparted practical scientific approach, to "hot" issues in our societies, while maintaining a simplistic common-person narrative, is quite an astounding feat. A loyal subscriber, always looking forward to your episodes.
@@bertilhatt Oh sounds great. Walt weak and sick from chemo instead of recovering immunologically through spontaneous remission while his wife cheats on him with her boss. Except with the purchasing power of the Canadian dollar, Walt's family would have a far lower standard of living.
I'm wrapping my brain around this. A surface being heated by the sun is COOLER than the ambient temperature. This is one of the closest things to magic I've ever witnessed. Wow!
Think of it this way instead: if the surface wasn't heated by the sun at all, it's backside would be even colder. Think of it more as it being highly resistant to sunlight, thus keeping things still relatively (still hotter than it would be without the sun, but still quite cool), than an actual "cooling effect because of the power of the sun itself".
Had to say, watching this for the second time, this is utterly amazing. I'm often critical and a bit of a 'know it all', as many of us blokes are. This is, from beginning to end, pure poetry for an engineer. The amount of thought and hard work is only part of it. The creativity and communication is too. The production and quality is first class. For some reason this viewing just blew me away and my mind has been flying on overtime with all sorts of ideas since. Someone who puts brains into this mode has to be just wonderful.
I love how the results are cutting-edge and yet the explanation and showcase of the production is so clear-cut that I actually feel like I have learned a lot about this subject despite having relatively no experience prior. That's incredibly hard to do as an expert in any field. Well done!
This is an absolute classic Tech Ingredients episode, I have heard about this super paint but had no idea it was this easy and inexpensive to make. Great video.
I think "easy" is a relative term here, but definitely doable outside of a factory, which is awesome. I'm personally not a fan of some of those solvents in workshop, but that's easy enough to work around, create a temporary solvent and paint drying booth with exhaust fans. What this should REALLY tell you, is, that at less than $5000 per ton for the raw materials and what we now know is required to manufacture it, there is zero excuse for this product to be sold at insane prices, especially given that the raw materials to make garden variety house paint are just slightly less than 1/2 the cost (titanium white for example is about $2000 per ton). The major downside is that even if this stuff hit commercial price parity with something like exterior paint, you're going to need 10 times as much of this product to cover a home for example (my last exterior painting required 22 gallons for 2 coats sprayed).
@@racerex340 When I say easy I mean comparatively easy. It isn't something that requires millions in investment to set up making it on a commercial scale and to make small batches at home is very inexpensive. You wouldn't really use it to paint a whole house, maybe use it as a coating for a heat exchanger or something like that.
@@schrodingerscat1863 I know, I was just being a dork about it. I could see a value in painting roof surfaces in extremely sunny places. Imagine the roofs of all of the buildings in Disney parks coated in such a material, how much energy could they save by dumping even just a percentage of the heat, or the roof of a surface in desert areas that experience a ton of solar heating? I'm also sure that with some additional research and development, products could be created and applications methods refined enough to require far fewer applications to hit the appropriate thickness level required.
My grandparents retired to AZ border in the mid-70's, to a totally planned community. The one thing I ever heard negative was having to seal the place up in June and leave the country to spend a few months on a beach, b/c it was so much cheaper than the developer's rustic "look and feel" flavoring sprinkled all over the place. I had a blue-ribbon chemist in my Dad's family also, and we knew about this tech. We laughed. That was the last of the post-WWII do-whatever-you-want, shoot-the-moon era. Now we have no choice but to be clever, and it looks like an improvement!
@@racerex340 When we crunch all the numbers and look at money spent versus money saved, the most economical option for general use is still just to coat with a regular white paint and insulate very well. Because those few degrees of sub-ambient cooling will benefit the building the most if the bulding is not insulated at all. Any insulation will limit what that sub-cooling can do for the conditioned space. But if we leave the building uninsulated, we waste a lot of energy. Plus, there will only be subcooling when that surface is kept absolutely immaculate. Which would require tons of regular maintenance. Which costs lots of money and resources. Any speck of dust or dirt or leaves or cobwebs will greatly diminish its ability to reflect sunlight so efficiently. And then the insulation will be the most important factor once again. So yes, I am excited about this information, but we do need to be realistic about its practical application in the short term, until more streamlined ways are created to maximize its benefits. I can see this kind of surface being very useful for applications where the added bulk or weight of normal insulation would be less desireable, and keeping it super clean wouldn't be too much of a concern.
Brilliant way to make use of educational content and inserting some comedy. I remember hearing about some study or fact that students need a short break every 30-40mins during lectures/classes, because without that short break the mind starts to drift and stop paying attention. With that in mind, the short comedic skit you did was at the perfect moment. It immediately got me to laugh and then pay more attention. Bravo!
Tech Ingredients seems to be pioneering the "explain-every-little-bit-of-detail" technique. And as someone who always has so many questions to ask but can only ask a few, I LOVE it.
You guys have perfected the art of mixing professional quality with a fun laid-back attitude. Love the little jokes with the big bag of powder and the brews. This might be my favorite upload of yours. Another great production, I would love to get together with my dad and do experiments and projects like you guys

15 years ago I suggested to a co-worker at Invisalign that materials sciences still had several decades of achievements and was still the biggest area of innovation available to humanity. This video was a great example of how we still have a ways to go in getting to real solutions to practical problems.
Great vid. One small correction: while often used together with surfactants for better penetration, EDTA itself is not a surfactant, but a chelating agent ( from Greek χηλή, chēlē, meaning "claw"). Its molecules surround the barium (and other metals) ions to form a complex, much like holding a tennis ball in your hand. I reckon this inaccessibility limits crystal growth, making them smaller, but I don't have a source on this, just makes chemical sense.
All thumbs are fingers but not all fingers are thumbs. I present this to you as EDTA does act as a surfactant. A surfactant's job is to surround bits of stuff with a micelle. This allows for betters dispersion of the "dirt" or whatever you're trying to homogenize or remove better. EDTA is creating a sort of micelle by wrapping around the "dirt" in this scenario which is oxidized aluminum and such. It acts as the "claw" you are referring to. Wraps around and segregates the particle away from interacting with others putting it in a suspension. It is acting in the same exact way in this scenario so the use of surfactant is completely logical in this instance. You can argue semantics but that has no place among those just trying to relay something in a way you can understand. Edit: Dispersion does not require a micelle to be clear, you can do it with a myriad of techniques. The micelle example is the simplest to understand as you just need to know how soap works.
@@larrysmith8138 Chelation (by chelator) and micelle formation (by surfactant) are two completely different things. EDTA is no surfactant and it does not form micelles.
@@user255 In fact, they do create a psuedo micelle if you would just get off the definition kick. A chelating agent like EDTA forms a bond completely around said particle and prevents aggregation just like a micelle would forming its hydrophobic and hydrophilic layers around a particle. This is the property that is so great with EDTA as it keeps the particle in question "suspended" from interactions it would normally acclimate to so that your body can expel it in cases of metal poisoning. So just as soap keeps lipids from aggregating, EDTA prevents aggregation of the particle in question. Like I said, you can argue definition semantics, but in this case it is working in the same exact definition. This is what keeps book smart and street smart so very separated. I even alluded to this with my first reply to the user. Also, language is purely for taking a thought in one's self to another entity keeping the information in tact. Science dwells in keeping exact definitions pure so that we can all be on the same page. The brilliant man in the video simply used language to express an idea that that ties to the scientific definition very very well just to inform your butt.
@@larrysmith8138 _"A chelating agent like EDTA forms a bond completely around said particle and prevents aggregation just like a micelle would forming its hydrophobic and hydrophilic layers around a particle."_ Not true. Chelator forms chemical bond with a metal atom (or ion). It does not cover anything and it does not prevent aggregation. In fact you can easily crystallize some chelated metal ions. Micelle is more like mechanical structure, which arises from Van der Waals force. There is no chemical bonding. While you find superficial similarities between the two, that does not mean they are the same.
As a mechanical engineer and a person who is hungry for learning, I follow your projects with pleasure, your scientific methods open my horizons. Thank you from the heart, I wish you good health.

That tiny correction underlines how the doctor effortlessly expresses a huge amount of highly technical detail. Your communication skills are truely impressive, Doctor. I'm a big fan.

You're awesome, chemistry is awesome. I love how you approach and dispell ignorance. I love that you're tackling HVAC without using exotic coolants to pump heat.
To be so factual, informative, and educational AND blow it out of the water with that humor near the end. I laughed until I cried and STILL came away with a higher, more broad knowledge base. Awesome work, it would be an absolute thrill and honor to spend time around y'all
This channel deserves 10x the subscribers it currently has. So calm and clear talking (not always the case in other popular channels) and clear explanations!

I made this with barium nitrate! 2:2:1:2 with barium nitrate:edta:drain cleaner:sodium sulfate! I tested it and the byproduct is pure sodium nitrate and makes the plants in my garden really happy! The PH matters, like you said in the video, and I've found that a ph of about 6.2 makes the best size particles!

Just wow! Guys like you and NightHawkinLight are contributing huge chunks to domestic labs world wide. Just your developing the tech to be the best it can be for ordinary jokers out in the day to day environment blows me away. Bloody impressive effort with trying to make the best coating you could, regardless. Respect.
Making the world a better place will take millions of different "small" contributions like this. Your videos give us confidence that it can be done if a small group of people pick it up and take it to the next level. By putting it out there, you also ensure that anyone can pick it up who is willing to do it.
I get SO excited whenever I see a new upload from y'all and the excitement is linearly proportional to the length of the video. Keep up the quality edutainment!
This is incredible, and I don't just mean the technology on display, but everything about this video. Teaching so much in single takes, explaining pretty much everything anyone would need to replicate this themselves, and even adding in humor here and there. I can't imagine how much time, skill, and effort went into even just one of these videos, and to top it all off, the information is invaluable for a home owner. It's also just really enjoyable listening to you teach. I'll definitely be checking out some of your other videos and sharing them with my father to see which parts of it he wants to implement in our home.
Excellent topic, demonstration and production! The perfectly nerdy comedic moments are appreciated!!! You make science and engineering beyond entertaining and fun enough to share with my non-engineer wife and kids!!!!
In the event you happen to see this, I ended up doing something similar when trying to find an emulsion that would double as a surface coating material for my early graphene experiments and ended up using kosher glycerin as the suspension medium, 80/20 acetone/xylene as the solvent (evaps quick but not so fast that it creates surfacing issues), xanthan gum if you don't need it water-resistant, and a reptile heating pad beneath the surface to be coated to reduce layering times. I've since refined my procedure to get away from needing strong acids in the separation phase, though when you mentioned surfactants, it reminded me of a trial when I experimenting with bubble-blowing solution. It also made for an impressive base coat as it remains quite adhesive through a nice range of temperatures and can be cross-linked later to lock in the structure, not to mention it's Real cheap at the end of summer if you're looking to get it in bulk cheaper than supplies to make it can be acquired.
Not only are you about the most intelligent human being I've ever seen, you're also extremely fun!! Your sons have no idea how lucky they are to have a Dad that can teach them all about science, and then go apply it in an extremely entertaining manner. I can just about see you saying, "hold my cold filtered draft malt beverage!"
Ive been researching this for months now and I'm so happy that you came across this yourself. I wanted to make this paint but lacked the confidence to do it on my own. Now with your guidance I'm excited to try this.
It's been a while since Ive watched your videos (I like to binge watch), and I have to say; I'm pleasantly surprised by the new, looser presentation style! It definitely wasn't needed, as I very much enjoyed the balance you struck before, but it's really nice to see you two having fun with it and showing your more humorous side. The filming and editing has also gotten very good. Again, it was perfectly good before, but I'm really enjoying the more cinematic scenes and set work. I didn't think I could enjoy you guys any more than I already did, but you've outdone yourselves. It's really nice to see a father and son duo having so much fun and being so productive together. It really is heartwarming and always inspires me to do the same with my son. Finally, I want to add: I see you as an excellent example of what I strive to be like. You share a similar philosophy of ethics, interest in science/manufacturing, sense of humor, familial goals etc., as I do. You're not only teaching me about the subjects of your videos, but you're offering a real-world depiction of what I've always hoped to achieve in my personal life. I couldn't appreciate you guys more! Thanks for everything! Truly.
I cant like your comment OP bcuz its at my fave number 88 but I do like your comment despite the lack of an extra like tallied on that thumbs up button indicator / badge.
Note there's BaSO4 based "Primalex Polar" paint available in Europe, it's only designed for indoor use and it might not have the right particle size, but perhaps worth trying.
I stumbled upon your channel a couple months back when looking up how to make a cloud chamber for a science fair-like project and I keep being amazed with the content you put out there. My ADHD brain usually makes it hard to follow lengthy videos, but your format makes it very easy to do so and every video I've watched made me look more into the things you're showcasing. Thank you very much for all the effort you're putting in your content.
I like to overspray onto one test spot and use a touch test on it to see if things are dry. I'll make sure to spray that spot last to make sure everything else has been dried enough. Your channel is amazing and I love everything you and your camera team do! I appreciate how thorough you are. :)
I wish your UA-cam videos were used by my science teachers, first to watch it, then to recreate it. I would have paid more attention in class and would have probably traveled a different path. You sir are a teacher of teachers!
Truest statement yet. I concur. Like many, our generation too was well...assaulted.He is indeed a teacher, of teachers. That's why he has the position. Not all of us have been so fortunate.
Fascinating video as always. I don't typically think of EDTA as a surfactant, but as a chelating agent. Surfactants are typically dealing with liquid-liquid or liquid-glass interfaces. I generally see surfactants in the context of some hydrophobic - hydrophilic interaction, where some hydrophobic species is insoluble in an aqueous solution and the addition of a surfactant (Triton-x, SDS, etc.) aids in dissolution.
Each time I watch your videos, I'm always amazed that we get to watch a genius applying his talents to little projects around the home. This is the most unique channel on UA-cam.
Amazing video! Some time ago I needed a white paint with a high reflection coefficient and I had a package with medical barium sulfate. And it didn't work out for me in the end. It was the wrong barium sulfate. It, despite the small particle size, is very poorly distributed in the paint. Instead of a homogeneous mass, lumps and flakes of very different sizes are obtained, no matter how much you mix. The situation can be corrected if a ball or roller mill is available. But these devices are so expensive that buying them for the sake of getting several tens or hundreds of grams of paint is utter madness. Thanks to this video, as well as a video about the preparation of a similar calcium carbonate pigment from the NightHawkInLight channel, my eyes seemed to open! This is an amazing effect that can be obtained as simply as cooking scrambled eggs! Regarding a suitable binder for paint, I want to ask the author of the channel: have you tried using acrylic dispersion, which is often used in water-dispersion paints? It meets all the necessary requirements. It has a sufficient volume during the preparation of the paint and significantly loses it as it dries. Non-toxic, does not smell. The acrylic resin contained in the solution in the form of an emulsion, after solidification, gives a transparent plastic. Why not use this binder? And the author missed one point. Soluble barium salts, unlike sulfate, are VERY toxic. They are sometimes used to kill rats. Therefore, when handling barium chloride, all precautions should be taken, as with any toxic substance.
Regarding the acrylic emulsions, I did try several supposedly "clear" acrylic coatings as the base. One was from Minwax, another was from Sika, and the third was from an art supplies retailer. All these coatings generated a very slightly yellow mixture.
Every one of these is an absolute masterclass in whatever topic it covers. I once again find myself enthralled in a topic that I had no interest in previously.
I don't have any of the tools or the room needed for those tools... But this process is very exciting. Not only is this doable in a relatively low tech environment, but the impressive thermal performance gives this actual tangible real life benefits. Considering the effort and stench of applying those 30 layers yourself, I hope for availability as ready to use sheets or plates at some point. Could be incredibly useful to shield homes from the sun. After all, a home fully clad in this material would be literally cooler than the air outside without any extra effort.
Thank you for helping to rekindle my love of science and tech! I really, REALLY appreciate videos like yours that are evenly paced, no unnecessary music or sound effects or trying too hard to be funny. It's just so nice being able to listen to you speak without all of those things that normally so clutter up other science & tech videos on here. Your videos are so well edited too, speaking as someone who edits video for work! It's an artform to get cuts to feel like they don't take anything away from what's happening, or interrupt the flow. Thank you!
What an amazingly intuitive explanation of such a seemingly complicated process. I’ve always found your content so enthralling. Thank you for everything you do, you make learning so much fun.
Impressive! The whole process can be fairly easy to fit into a production line. My only concern is - how well this "super coating" can survive in real world conditions, like rain, snow, wind etc.?
Another experiment that you could do with these coatings is send some samples up on a weather balloon and log the different temperatures. One of the concerns with flying stratospheric scientific balloons is the over heating of the aluminum gondola structure. When I was a part of the AESOP and LEE payload program at Bartol Research Institute, we were advised to paint any exposed aluminum with "appliance white" paint. (Sorry, I don't remember which brand so I apologize for how imprecise that description is.) It would be interesting to see how well this coating works at high altitude. One big issue might be the lack of azimuth control on small, hobby balloons. Maybe coating cylinders and stringing them vertically (to avoid shadows) would work.
Could you formulate a powder coating preparation? It requires a little more processing but I would think that you could apply the layers much faster with less drying time in between. There are acrylic powder coating systems out there.
It may be interesting to spray upward onto a panel and vary the charge a bit to help ensure a variety of particle size ahead of the baking/curing stage.
Only problem with powdercoating is (a) the airborne nano-particles may not be so great to breathe in, even with respirators and (b) powdercoating is not an option for people who are looking to paint their roof or do any retrofit painting on already existing building walls, roofs etc. and (c) it is only good for smaller items that can fit in a powdercoating oven
I've never subbed to any channel before, and I've been around for decades(!). This goes to show how much I *love* the topics your projects cover. And how much I *love* the way you explain them. Furthermore, that comic relief through the coating phase officially makes you a national treasure of a man, for me.
Living in Thailand, this is really fascinating. Trying to figure out A) where I can get all those chemicals locally, and B) a process to make a few hundred sq. meters of these things. When it's over 100°F in the shade, anything you can do to lower the temperature of your structure is worth it. The questions I do have are: 1) does humidity have any effect on the efficiency of radiation, and 2) how long will these panels last in direct sunlight in the tropics? The sun here is very strong with lots of UV. Finally, I need instructions on building a Star Trek style matter transporter so I can beam away your case of Sam Adams. Stuff is over $5 USD per bottle over here if you can find it. That would be the most expensive part of the project.
Ha! The humidity will reduce the IR transmission of the atmosphere and increase its apparent temperature from the ground, but not much. As I described in the previous video, the cooling effect increases with the surface temperature at T^4, so the benefit of the paint will be significantly greater at your higher temperatures despite the higher humidity.
I’m concerned about the condensation of water on the panel surface in humid tropical air. That water film on the panel will probably affect efficacy. Keeping the panel surface air dryer by using a cover box that’s mostly air tight will be a challenge I think?
This is just some excellent viewing. Learnt so much from this and actually want to give it a go. With the surfactant thing, I always like to mention that the difference between olive oil and mayonnaise is the surfactant in eggs. It such a tiny amount by weight in comparison to the oil but has such a massive effect and really shows how much it can change the structure of something.
excellent presentation. i appreciate the fact that you acknowledged, at the very end, that ambitious entrepreneurs in search of a profitable niche industry have just had it presented to them on a barium-coated silver platter.
I would be very excited to see a Part 3 video showing a full system incorporating this technology. Its total cost of construction, its total wattage/BTU of cooling, comparisons with other electrical-based technologies powered by a similar area of solar panels, etc.
My mind is blown, I sat through the entire video, and was thoroughly impressed by the end result, not to mention the humour is right up my alley. 10/10 video imo
I am in the refrigeration service business and this is incredible! Refrigeration coils often placed on roofs in direct blazing sun coated with this could be many times more effective at releasing more heat if the coils where not soaking up radiant heat from the sun😮
Awesome! Now someone needs to sell rolls of adhesive with this paint, as well as plastic sheets with this paint, so people can easily and cheaply use them to cool their houses and other structures, without having to do the mixing and spraying themselves. And for up to 10-20 times the price of normal paint, a lot of people will end up using them in the hotter areas, especially hot-and-humid areas.
Always a learning experience! And getting funnier, too, sniffs… I really do value the ideas, the demonstrations, and the everyday practicality of the stuff that you do. I’m forwarding this episode to Matt Ferrill of “Undecided”, because he’s building a new house with the latest technologies to make it as efficient as possible. This is something he needs to look into… Thanks again!
Im ashamed yo admit that the majority of this video was greek to me. With that said, i soaked up every second of it! I'm so unbelievably fascinated by this that I'm going to take the time to research every word, term and ingredient that i didn't understand or know what it was and make myself a "script" of sorts that i can comprehend. I can't thank you enough for taking the time to make this video and suffer through having to consume all those beverages in an attempt to stay hydrated during the process 😂
I absolutely love that you are sharing technology like this with all the people of the world! You are a true gentleman and scholar! I hope to either make or purchase this paint in the future for personal projects, this is revolutionary!
The more I watch these videos, the more curious I get about how you learned all this, and what you did in the past to know so much...would love to hear the origin story.
Great video! I love how you can explain the science without sounding boring as heck or like you're trying to sell me something, and the bits of comedy makes it feel light hearted without taking away from the scientific content! BTW: that bit with the last coat of paint had such a "Leonard from The Big Bang Theory" energy xD
I've been waiting for this video! Knew it was going to be based off the same concept of nighthawks video. Also, as soon as I saw the box with balls, I remembered the thermal paste episode, and knew where you was going to go with the idea of making different sized nano-particles. Honestly, Making this stuff on an industrial scale, or making panels of this stuff at scale ( since most regular people don't want to wait 20 minutes between coats, on a 25 coat project, especially if they are painting something fairly large ), wouldn't be the worst business idea, and would have real world uses, especially in the sunnier / warmer climates. I could see not wanting to paint entire walls with this, as in the winter, this paint will help suck the heat out of your house, and throw it into the sky. But in areas that don't get super cold at night, or stay hot all year round, This could drastically cut down cooling costs. A fun DIY project could be making a decent sized panel, with reflective walls ( like you made in the first video ), and like your original video, connect it to some water cooling, but make it a closed loop system, A radiator could be placed in a hot section of your house ( such as an attic ), or in a shed. Could get cool air into a hot area, for very little cost ( wattage ). Cooling is one of the largest users of electricity ( and thus, fossil fuels ) in the world. We can heat stuff all day long, with just about anything. Generating heat is fairly simple ( Containing it is the problem ), But generating cold ( moving heat away from a specific area ) is so much more energy intensive, It's almost a cruel joke that thermodynamics is playing on us. Finding any way to cool a specific area, for very little or no energy usage ( continuous usage. Mining, and creating the stuff takes energy though ), Is almost a holy grail achievement. Even if you couldn't "cool" something, but could just offset the heat the sun is dumping on an area would make such a large difference. These two video's have been by far, one of the most interesting subjects you have talked about on this channel, at least to me. Thanks for all the hard work, research, clear explanations, and time you put into making these videos. Can't wait to see what you teach us next!
Generating cold is just as energy intensive as heating. Why do you think that there would be a difference? In fact in most everyday use generating cold requires less energy. Using heat pumps for cooling is the norm (with efficiency of 300% or so) Whereas most heating still is done with burning stuff (efficiency around 90% or so)
well in the winter You could just restrict water flow to the cooling pannels so they wouldn't really be sucking heat from your house, remember this relies on the flow of warmer water.
@@jolioding_2253 depends on your implementation. A simpler solution than building a water-cooling-loop would be to just paint your roof. That's what the OP is talking about.
@@Jehty_ in this video he demonstrated just a painted surface bin in the last video he talked about using a water loop and this is an addendum to the last one
Something amazing about the internet, if your parents didn't have certain qualities you wish for, you can find aspects of them on UA-cam, like this channel. 10/10. This channel is going to 3+ million subs for sure.
Man you really put an effort to show how good this is. Thank you for helping others, besides that you and your team most enjoy what you do. For some time I've been looking for paint that does exactly what you and your team just did. I'll probably try to replicate this and apply it to my house. Have a wonderful day.
I'm facinated to know his back story and what he trained in (there's a big gap between leaning and applying). It's easy to get set down a narrow path in life.
2 Remarks: A: If you want to ingest some material, you don't just want to make sure that that material itself is safe, but also that there are no contaminants left over from the production that may be harmful in the amounts present. B: In your centrifuging and drying procedure, the wet BaSO4 is wet with _salt water_. You can get that remaining salt out if you mix it with pure water (distilled or de-ionized water, otherwise you might just exchange salt for limescale) and send it through a second centrifuging pass before drying away the water.
A: Yes, that's why I buy expensive "food-grade lye" even though I can get a case of the same stuff cheaply, sold as drain cleaner. People are amused or confused by the term "food-grade" applied to a toxic substance, which illustrates its actual meaning.
This was such an interesting test, with a really easy to follow guide. I hope to see this pop up more and more in everyday life. Keep up the great videos! Much love from PA
Really excellent job! Great to see this method with the microspheres taken to what I think is probably its full potential, and in a way that's totally doable outside of a lab. It's also very impressive to achieve sub ambient temps without any sort of film or insulation. It must be radiating a fair amount of w/m^2 to overcome the breeze blowing over it. Very well done, and it was especially useful to include info about bulk suppliers.
I'm still working on new methods myself. I'll be thrilled if I can hit similar numbers as you have.
Thanks.
I appreciate the comment and for your earlier video that got us started down this path.
Good luck!
@@TechIngredients So how about the polar opposite now, a paint that absorbs as much heat radiation as possible.
Could be interesting for a purely convection based heat pump.
Would be slow, but cheap to run 😉
@@DerSolinski that's exactly what I was thinking. Then I could have two separate roof panels to climate control my chicken coop year round with no power.
@@DerSolinski You're mentioning two different methods of heat transfer here.
If you're absorbing solar radiation you want a solar heater (I think they already did a video on that). If you're looking for an air cooled convection based system you have a different heat transfer coefficient related to how efficient the surface of a radiator is at exchanging heat with moving air. It's a different problem, but still interesting.
Muso black would probably adsorb the most heat but it’s cost prohibitive. I’d try black 3.0 as a starter.
Just pre-emptively expressing here: Please do not change the format of your channel. It is perfect the way it is. It's so nice to listen to you without background music and overcommercialization or overproduction. You can see this creeping in old Mythbusters episodes and by the end of 8 seasons, the show was unrecognizeable. Tech Ingredients cannot be perfected anymore, it is epitome of high quality, small business vibe production. Thank you for everything you do.
Agreed.
Good call. The format is bang on. I also appreciate how accessible they make most things. For example explaining an affordable solution to make a mixer into a heated mixer. Even though he had the relevant equipment and you can purchase the equipment from the same place as the parts he suggested as an alternative, affordable solution.

This was always the dream of the web: to freely share ideas, innovate, and communicate. I have so much respect for the quality of your content, the production quality, the writing, the delivery, it's all fantastic, but the part that really blows me away is the commitment to getting the information out to the world, without putting it behind a pay wall or patent. You are truly working to improve the world, not just your own experience in it.
Wow, thank you!
I absolutely concur! it's natural selection
Well said, nothing to add.
This is rare on UA-cam to come to this point of measurable and traceable developments with absolutely no other motive than sharing it with everyone. This is so inspiring and gives me hope in humanity. A few more of these guys and we d make so many more discoveries. Sure some researchers probably did this and published it, but this guy here brings it to the masses. Love this channel, pure gold
OP very well said and expressed eloquently.. Unlike my redundant statement here hahaha
I love living in the modern age. So much information is so freely given by people who I would NEVER have the luxury of meeting in real life, let alone enough time for them to teach me all of the amazing information they have in their heads. The only way to learn about stuff like this in such an in-depth way would be spending thousands of dollars going to college.

In Aerospace, when we solvent clean aluminum, the technique is to wipe the solvent on with a fully saturated cloth, wetting the entire surface, and then wipe it off with a clean cloth before it can evaporate. Then repeat as necessary. That prevents the oils and dirt from redepositing as the solvent evaporates.
I had my shed painted with one of those products in Australia and before in the summer you couldn’t work in that shed and now it’s cooler in the shed than outside I was hugely impressed and highly recommend it.
could you tell us more about the product you used

Hi Deon, what paint did you use mate?
I can't express how much I love this. As a fellow engineer interested in thermal science I love this
What i really love about this channel is that it is not just cool science on this channel, but it is a practical DIY kind of science.
There's only two kinds of sciences which are fun: applied and theoretical - everything in-between sits out of context of anything that seems relevant and therefore will bore the shit out of you.
So in other words... technology?
@@ObservingLibertarian Ok, but that's not really what they're commenting on. Not all applied science has a meaningful DIY component, which is a large basis of this channel's content. That's what OP is talking about, not whether there's anything beyond applied or theoretical science.
For me it's what can I add to my dream house science
I absolutely love the mildly comedic flavor of this episode. Science focused channels have a tendency to be a bit “robotic”, but your personality is one of a kind. Thank you for all of the amazing videos!
I completely disagree. I found the comedic elements are off-putting. They don't fit with the genre of the video. By its nature, the comedic content has to be somewhat fictionalized, and so its inclusion in what is otherwise a truthful instructional video makes it hard to take the rest of the video seriously.
@@rorypenstock1763 Different strokes I suppose. I love science and I love to laugh, so this was perfect for me.
@@rorypenstock1763 They kept the comedic parts limited to "how do we make watching paint dry interesting?" so it really doesn't detract from the episode at all. Adding balls jokes made it memorable. Completely disagree with you disagreeing Rory.
yes sir ....your content was always perfect and very understandeble. Now even better because you and your sons mix in a little bit more humor
every day. You are one of the very few "serious" science channels on youtube that figed this out , just like Sabine Hossenfelder. It used to be old knowledge that people , if they are not already a specialist in the field your speech or demo is gonna be about....can only give you full attention for 15 minutes. Then you need a gentle reset with some humor and/or acting. You are doing that perfect.
Same here, almost closed the video at drinking propagation, saddly @Tech Ingredients do not appreciate the viewers time any more
As someone who painted cars professionally, I always made a swatch (usually sheet metal because that's what cars are made of )and prepped/painted it at the same time and in the same manner as the vehicle I was painting.
I would then use that to test whether or not the paint on the vehicle itself was ready for another coat or the next process and wouldn't have to touch the vehicle.
I would also keep these swatches, in addition to photos of the vehicle in what was my portfolio.
Can we appreciate this guy trying to both teach and show us how to solve real problems at home? Keep it up! Definitely watching more content from you and subbed!
Thank you!

I really like this guy. He's freaking hardcore! Tells you where to source the stuff. Make your own world's shiniest paint. Drills down into the details of why he's doing each particular step. I especially liked that part, that information is useful for whenever I paint anything not just this thing. Consider this shared.
Not only that, but his subtle jokes are quite funny and unexpected from a guy that looks so prude. Easily the greatest channel on UA-cam.

More than that he shares his own discoveries. A great thing. Really a great thing.
Love the sublime comedic homage to Walter White (with all the sniffing and masks).

I'm wrapping my brain around this. A surface being heated by the sun is COOLER than the ambient temperature. This is one of the closest things to magic I've ever witnessed. Wow!
Check out our last video where I explained how this is possible.
I’m a Professional Engineer and actually thought this was an April fools joke. Amazing simply amazing.
Think of it this way instead: if the surface wasn't heated by the sun at all, it's backside would be even colder. Think of it more as it being highly resistant to sunlight, thus keeping things still relatively (still hotter than it would be without the sun, but still quite cool), than an actual "cooling effect because of the power of the sun itself".
How stable to rain and uv is this material?
It's Clarke's Third Law.
Had to say, watching this for the second time, this is utterly amazing. I'm often critical and a bit of a 'know it all', as many of us blokes are.
This is, from beginning to end, pure poetry for an engineer. The amount of thought and hard work is only part of it. The creativity and communication is too. The production and quality is first class.
For some reason this viewing just blew me away and my mind has been flying on overtime with all sorts of ideas since. Someone who puts brains into this mode has to be just wonderful.
I love how the results are cutting-edge and yet the explanation and showcase of the production is so clear-cut that I actually feel like I have learned a lot about this subject despite having relatively no experience prior. That's incredibly hard to do as an expert in any field. Well done!
he's amazing.
seriously this is so well explained in this video
I really hope this would cut cooling emissions in the world
teachers should be required to study his videos to learn how to teach :P
This is an absolute classic Tech Ingredients episode, I have heard about this super paint but had no idea it was this easy and inexpensive to make. Great video.
I think "easy" is a relative term here, but definitely doable outside of a factory, which is awesome. I'm personally not a fan of some of those solvents in workshop, but that's easy enough to work around, create a temporary solvent and paint drying booth with exhaust fans.
What this should REALLY tell you, is, that at less than $5000 per ton for the raw materials and what we now know is required to manufacture it, there is zero excuse for this product to be sold at insane prices, especially given that the raw materials to make garden variety house paint are just slightly less than 1/2 the cost (titanium white for example is about $2000 per ton). The major downside is that even if this stuff hit commercial price parity with something like exterior paint, you're going to need 10 times as much of this product to cover a home for example (my last exterior painting required 22 gallons for 2 coats sprayed).
@@racerex340 When I say easy I mean comparatively easy. It isn't something that requires millions in investment to set up making it on a commercial scale and to make small batches at home is very inexpensive. You wouldn't really use it to paint a whole house, maybe use it as a coating for a heat exchanger or something like that.
@@schrodingerscat1863 I know, I was just being a dork about it.
I could see a value in painting roof surfaces in extremely sunny places. Imagine the roofs of all of the buildings in Disney parks coated in such a material, how much energy could they save by dumping even just a percentage of the heat, or the roof of a surface in desert areas that experience a ton of solar heating? I'm also sure that with some additional research and development, products could be created and applications methods refined enough to require far fewer applications to hit the appropriate thickness level required.
My grandparents retired to AZ border in the mid-70's, to a totally planned community. The one thing I ever heard negative was having to seal the place up in June and leave the country to spend a few months on a beach, b/c it was so much cheaper than the developer's rustic "look and feel" flavoring sprinkled all over the place. I had a blue-ribbon chemist in my Dad's family also, and we knew about this tech. We laughed. That was the last of the post-WWII do-whatever-you-want, shoot-the-moon era. Now we have no choice but to be clever, and it looks like an improvement!
@@racerex340 When we crunch all the numbers and look at money spent versus money saved, the most economical option for general use is still just to coat with a regular white paint and insulate very well. Because those few degrees of sub-ambient cooling will benefit the building the most if the bulding is not insulated at all. Any insulation will limit what that sub-cooling can do for the conditioned space. But if we leave the building uninsulated, we waste a lot of energy. Plus, there will only be subcooling when that surface is kept absolutely immaculate. Which would require tons of regular maintenance. Which costs lots of money and resources. Any speck of dust or dirt or leaves or cobwebs will greatly diminish its ability to reflect sunlight so efficiently. And then the insulation will be the most important factor once again. So yes, I am excited about this information, but we do need to be realistic about its practical application in the short term, until more streamlined ways are created to maximize its benefits. I can see this kind of surface being very useful for applications where the added bulk or weight of normal insulation would be less desireable, and keeping it super clean wouldn't be too much of a concern.
Brilliant way to make use of educational content and inserting some comedy. I remember hearing about some study or fact that students need a short break every 30-40mins during lectures/classes, because without that short break the mind starts to drift and stop paying attention. With that in mind, the short comedic skit you did was at the perfect moment. It immediately got me to laugh and then pay more attention. Bravo!

15 years ago I suggested to a co-worker at Invisalign that materials sciences still had several decades of achievements and was still the biggest area of innovation available to humanity. This video was a great example of how we still have a ways to go in getting to real solutions to practical problems.
Great vid. One small correction: while often used together with surfactants for better penetration, EDTA itself is not a surfactant, but a chelating agent ( from Greek χηλή, chēlē, meaning "claw"). Its molecules surround the barium (and other metals) ions to form a complex, much like holding a tennis ball in your hand. I reckon this inaccessibility limits crystal growth, making them smaller, but I don't have a source on this, just makes chemical sense.
Thanks, I was making this same correction.
All thumbs are fingers but not all fingers are thumbs.
I present this to you as EDTA does act as a surfactant.
A surfactant's job is to surround bits of stuff with a micelle.
This allows for betters dispersion of the "dirt" or whatever you're trying to homogenize or remove better.
EDTA is creating a sort of micelle by wrapping around the "dirt" in this scenario which is oxidized aluminum and such. It acts as the "claw" you are referring to. Wraps around and segregates the particle away from interacting with others putting it in a suspension.
It is acting in the same exact way in this scenario so the use of surfactant is completely logical in this instance.
You can argue semantics but that has no place among those just trying to relay something in a way you can understand.
Edit: Dispersion does not require a micelle to be clear, you can do it with a myriad of techniques. The micelle example is the simplest to understand as you just need to know how soap works.
@@larrysmith8138 Chelation (by chelator) and micelle formation (by surfactant) are two completely different things. EDTA is no surfactant and it does not form micelles.
@@user255 In fact, they do create a psuedo micelle if you would just get off the definition kick.
A chelating agent like EDTA forms a bond completely around said particle and prevents aggregation just like a micelle would forming its hydrophobic and hydrophilic layers around a particle. This is the property that is so great with EDTA as it keeps the particle in question "suspended"
from interactions it would normally acclimate to so that your body can expel it in cases of metal poisoning. So just as soap keeps lipids from aggregating, EDTA prevents aggregation of the particle in question.
Like I said, you can argue definition semantics, but in this case it is working in the same exact definition.
This is what keeps book smart and street smart so very separated.
I even alluded to this with my first reply to the user.
Also, language is purely for taking a thought in one's self to another entity keeping the information in tact. Science dwells in keeping exact definitions pure so that we can all be on the same page.
The brilliant man in the video simply used language to express an idea that that ties to the scientific definition very very well just to inform your butt.
@@larrysmith8138 _"A chelating agent like EDTA forms a bond completely around said particle and prevents aggregation just like a micelle would forming its hydrophobic and hydrophilic layers around a particle."_
Not true. Chelator forms chemical bond with a metal atom (or ion). It does not cover anything and it does not prevent aggregation. In fact you can easily crystallize some chelated metal ions.
Micelle is more like mechanical structure, which arises from Van der Waals force. There is no chemical bonding.
While you find superficial similarities between the two, that does not mean they are the same.

I can't imagine how much time, skill, and effort went into even just one of these videos, and to top it all off, the information is invaluable for a home owner. It's also just really enjoyable listening to you teach. I'll definitely be checking out some of your other videos and sharing them with my father to see which parts of it he wants to implement in our home.
That combination of food, technology and chemistry really peaks my interest and I would love to see more on this subject.
Will do!
Excellent topic, demonstration and production! The perfectly nerdy comedic moments are appreciated!!! You make science and engineering beyond entertaining and fun enough to share with my non-engineer wife and kids!!!!
In the event you happen to see this, I ended up doing something similar when trying to find an emulsion that would double as a surface coating material for my early graphene experiments and ended up using kosher glycerin as the suspension medium, 80/20 acetone/xylene as the solvent (evaps quick but not so fast that it creates surfacing issues), xanthan gum if you don't need it water-resistant, and a reptile heating pad beneath the surface to be coated to reduce layering times.
I've since refined my procedure to get away from needing strong acids in the separation phase, though when you mentioned surfactants, it reminded me of a trial when I experimenting with bubble-blowing solution. It also made for an impressive base coat as it remains quite adhesive through a nice range of temperatures and can be cross-linked later to lock in the structure, not to mention it's Real cheap at the end of summer if you're looking to get it in bulk cheaper than supplies to make it can be acquired.
Not only are you about the most intelligent human being I've ever seen, you're also extremely fun!! Your sons have no idea how lucky they are to have a Dad that can teach them all about science, and then go apply it in an extremely entertaining manner. I can just about see you saying, "hold my cold filtered draft malt beverage!"
Ive been researching this for months now and I'm so happy that you came across this yourself. I wanted to make this paint but lacked the confidence to do it on my own. Now with your guidance I'm excited to try this.
White powder joke! NICE! Thanks for sprinkling humor into the video! It is indeed a very good video, but the humor is like icing on top.
It's been a while since Ive watched your videos (I like to binge watch), and I have to say; I'm pleasantly surprised by the new, looser presentation style! It definitely wasn't needed, as I very much enjoyed the balance you struck before, but it's really nice to see you two having fun with it and showing your more humorous side.
The filming and editing has also gotten very good. Again, it was perfectly good before, but I'm really enjoying the more cinematic scenes and set work.
I didn't think I could enjoy you guys any more than I already did, but you've outdone yourselves. It's really nice to see a father and son duo having so much fun and being so productive together. It really is heartwarming and always inspires me to do the same with my son.
Finally, I want to add: I see you as an excellent example of what I strive to be like. You share a similar philosophy of ethics, interest in science/manufacturing, sense of humor, familial goals etc., as I do. You're not only teaching me about the subjects of your videos, but you're offering a real-world depiction of what I've always hoped to achieve in my personal life.
I couldn't appreciate you guys more! Thanks for everything! Truly.
YES!
Warms my heart that there's wholesome, intelligent role models like Tech Ing to aspire to and learn from. Gotta love gorgeous goofy geniuns!
I cant like your comment OP bcuz its at my fave number 88 but I do like your comment despite the lack of an extra like tallied on that thumbs up button indicator / badge.
Note there's BaSO4 based "Primalex Polar" paint available in Europe, it's only designed for indoor use and it might not have the right particle size, but perhaps worth trying.
I absolutely love this channel. Enjoy your "supplies", you deserve it!
I love a creator who respects his audience and doesn't dumb it down
I stumbled upon your channel a couple months back when looking up how to make a cloud chamber for a science fair-like project and I keep being amazed with the content you put out there. My ADHD brain usually makes it hard to follow lengthy videos, but your format makes it very easy to do so and every video I've watched made me look more into the things you're showcasing.
Thank you very much for all the effort you're putting in your content.
I like to overspray onto one test spot and use a touch test on it to see if things are dry. I'll make sure to spray that spot last to make sure everything else has been dried enough.
Your channel is amazing and I love everything you and your camera team do! I appreciate how thorough you are. :)
Thanks!
I wish your UA-cam videos were used by my science teachers, first to watch it, then to recreate it. I would have paid more attention in class and would have probably traveled a different path. You sir are a teacher of teachers!
Truest statement yet. I concur. Like many, our generation too was well...assaulted.He is indeed a teacher, of teachers. That's why he has the position. Not all of us have been so fortunate.
Fascinating video as always. I don't typically think of EDTA as a surfactant, but as a chelating agent. Surfactants are typically dealing with liquid-liquid or liquid-glass interfaces. I generally see surfactants in the context of some hydrophobic - hydrophilic interaction, where some hydrophobic species is insoluble in an aqueous solution and the addition of a surfactant (Triton-x, SDS, etc.) aids in dissolution.
It is used in detoxication of lead poisoning using its chelating property.
Each time I watch your videos, I'm always amazed that we get to watch a genius applying his talents to little projects around the home. This is the most unique channel on UA-cam.
Amazing video! Some time ago I needed a white paint with a high reflection coefficient and I had a package with medical barium sulfate. And it didn't work out for me in the end. It was the wrong barium sulfate. It, despite the small particle size, is very poorly distributed in the paint. Instead of a homogeneous mass, lumps and flakes of very different sizes are obtained, no matter how much you mix. The situation can be corrected if a ball or roller mill is available. But these devices are so expensive that buying them for the sake of getting several tens or hundreds of grams of paint is utter madness. Thanks to this video, as well as a video about the preparation of a similar calcium carbonate pigment from the NightHawkInLight channel, my eyes seemed to open! This is an amazing effect that can be obtained as simply as cooking scrambled eggs!
Regarding a suitable binder for paint, I want to ask the author of the channel: have you tried using acrylic dispersion, which is often used in water-dispersion paints? It meets all the necessary requirements. It has a sufficient volume during the preparation of the paint and significantly loses it as it dries. Non-toxic, does not smell. The acrylic resin contained in the solution in the form of an emulsion, after solidification, gives a transparent plastic. Why not use this binder?
And the author missed one point. Soluble barium salts, unlike sulfate, are VERY toxic. They are sometimes used to kill rats. Therefore, when handling barium chloride, all precautions should be taken, as with any toxic substance.
Regarding the acrylic emulsions, I did try several supposedly "clear" acrylic coatings as the base. One was from Minwax, another was from Sika, and the third was from an art supplies retailer. All these coatings generated a very slightly yellow mixture.
Every one of these is an absolute masterclass in whatever topic it covers. I once again find myself enthralled in a topic that I had no interest in previously.
Your explanation of aggregate density optimization using nano particles of various sizes is truly excellent. Ted
This is really cool! The fact that it can maintain subambient just with a bare panel is wildly impressive, super excited to see where this goes!
The presentation style and the density of information here, wow. Best channel on youtube
Thank you for this video.The details you provide in your video is amazing. I couldn't believe I watched it for 49 minutes, it was like 15 minutes.
I don't have any of the tools or the room needed for those tools... But this process is very exciting. Not only is this doable in a relatively low tech environment, but the impressive thermal performance gives this actual tangible real life benefits.
Considering the effort and stench of applying those 30 layers yourself, I hope for availability as ready to use sheets or plates at some point.
Could be incredibly useful to shield homes from the sun. After all, a home fully clad in this material would be literally cooler than the air outside without any extra effort.
Agreed
@@TechIngredients hi, how much this paint last? How many years it would cool the surface?
I wish this was available on some type of sheeting. Could be a really lucrative product. It would need some longevity to be practical.
I’ll spray my home with it! I’m in Las Vegas and we could sure use the extra help with our AC bills.
Soon bro
An actually useful channel, where you can learn something and get motivated to do it yourself! How come more people haven't subscribed!
Good question!
Thank you for helping to rekindle my love of science and tech! I really, REALLY appreciate videos like yours that are evenly paced, no unnecessary music or sound effects or trying too hard to be funny. It's just so nice being able to listen to you speak without all of those things that normally so clutter up other science & tech videos on here. Your videos are so well edited too, speaking as someone who edits video for work! It's an artform to get cuts to feel like they don't take anything away from what's happening, or interrupt the flow. Thank you!
Wow! Thank you.
You guys are hands down my favorite channel. Please keep up the hard work. We appreciate everything you do.
The results here are stunning. This is top-rate stuff, thank you for this.
You're very welcome!
What an amazingly intuitive explanation of such a seemingly complicated process. I’ve always found your content so enthralling. Thank you for everything you do, you make learning so much fun.
Impressive!
The whole process can be fairly easy to fit into a production line.
My only concern is - how well this "super coating" can survive in real world conditions, like rain, snow, wind etc.?
Clear coat over?
Another experiment that you could do with these coatings is send some samples up on a weather balloon and log the different temperatures. One of the concerns with flying stratospheric scientific balloons is the over heating of the aluminum gondola structure. When I was a part of the AESOP and LEE payload program at Bartol Research Institute, we were advised to paint any exposed aluminum with "appliance white" paint. (Sorry, I don't remember which brand so I apologize for how imprecise that description is.) It would be interesting to see how well this coating works at high altitude. One big issue might be the lack of azimuth control on small, hobby balloons. Maybe coating cylinders and stringing them vertically (to avoid shadows) would work.
it should work even better in high altitudes.
Add a dose of missile repellant..👨✈
I think you may be more concerned with egotistical politicians with their fingers on the giggle switches of their AIM-9X's 😅
I guess you have never heard the saying
Use sledgehammer to crack a nut
Or in today’s context
Use a jet fighter to pop a balloon
Or Joe Biden administration shooting it down with a half million dollar missile…
Every subject you cover, the thoroughness is always impressive. Just crazy smart.
Could you formulate a powder coating preparation? It requires a little more processing but I would think that you could apply the layers much faster with less drying time in between. There are acrylic powder coating systems out there.
I'll look into it.
It may be interesting to spray upward onto a panel and vary the charge a bit to help ensure a variety of particle size ahead of the baking/curing stage.
Only problem with powdercoating is (a) the airborne nano-particles may not be so great to breathe in, even with respirators and (b) powdercoating is not an option for people who are looking to paint their roof or do any retrofit painting on already existing building walls, roofs etc. and (c) it is only good for smaller items that can fit in a powdercoating oven
One of the fastest growing areas of robotic cobot development is in the powder coating industry.
I've never subbed to any channel before, and I've been around for decades(!).
This goes to show how much I *love* the topics your projects cover. And how much I *love* the way you explain them.
Furthermore, that comic relief through the coating phase officially makes you a national treasure of a man, for me.
Living in Thailand, this is really fascinating. Trying to figure out A) where I can get all those chemicals locally, and B) a process to make a few hundred sq. meters of these things. When it's over 100°F in the shade, anything you can do to lower the temperature of your structure is worth it. The questions I do have are: 1) does humidity have any effect on the efficiency of radiation, and 2) how long will these panels last in direct sunlight in the tropics? The sun here is very strong with lots of UV. Finally, I need instructions on building a Star Trek style matter transporter so I can beam away your case of Sam Adams. Stuff is over $5 USD per bottle over here if you can find it. That would be the most expensive part of the project.
Ha!
The humidity will reduce the IR transmission of the atmosphere and increase its apparent temperature from the ground, but not much. As I described in the previous video, the cooling effect increases with the surface temperature at T^4, so the benefit of the paint will be significantly greater at your higher temperatures despite the higher humidity.
I’m concerned about the condensation of water on the panel surface in humid tropical air. That water film on the panel will probably affect efficacy. Keeping the panel surface air dryer by using a cover box that’s mostly air tight will be a challenge I think?
Cheers for all the detailed cool concepts you guys radiate! Great practical edutainment, thought provoking stuff
I see what you did there...
Brilliant
This is just some excellent viewing. Learnt so much from this and actually want to give it a go.
With the surfactant thing, I always like to mention that the difference between olive oil and mayonnaise is the surfactant in eggs. It such a tiny amount by weight in comparison to the oil but has such a massive effect and really shows how much it can change the structure of something.
excellent presentation. i appreciate the fact that you acknowledged, at the very end, that ambitious entrepreneurs in search of a profitable niche industry have just had it presented to them on a barium-coated silver platter.
I would be very excited to see a Part 3 video showing a full system incorporating this technology. Its total cost of construction, its total wattage/BTU of cooling, comparisons with other electrical-based technologies powered by a similar area of solar panels, etc.
Amazing performance. Cooler in the sun than the shade? It's astounding.
I love this channel, i don't think I'm ever gonna apply this knowledge but its so well explained that the geek in me can't resist just learning.
My mind is blown, I sat through the entire video, and was thoroughly impressed by the end result, not to mention the humour is right up my alley. 10/10 video imo
I am in the refrigeration service business and this is incredible! Refrigeration coils often placed on roofs in direct blazing sun coated with this could be many times more effective at releasing more heat if the coils where not soaking up radiant heat from the sun😮
Agreed.
Maybe not many times, but it would definitely make a difference.
Awesome! Now someone needs to sell rolls of adhesive with this paint, as well as plastic sheets with this paint, so people can easily and cheaply use them to cool their houses and other structures, without having to do the mixing and spraying themselves. And for up to 10-20 times the price of normal paint, a lot of people will end up using them in the hotter areas, especially hot-and-humid areas.
Always a learning experience! And getting funnier, too, sniffs…
I really do value the ideas, the demonstrations, and the everyday practicality of the stuff that you do.
I’m forwarding this episode to Matt Ferrill of “Undecided”, because he’s building a new house with the latest technologies to make it as efficient as possible. This is something he needs to look into…
Thanks again!
Im ashamed yo admit that the majority of this video was greek to me. With that said, i soaked up every second of it!
I'm so unbelievably fascinated by this that I'm going to take the time to research every word, term and ingredient that i didn't understand or know what it was and make myself a "script" of sorts that i can comprehend.
I can't thank you enough for taking the time to make this video and suffer through having to consume all those beverages in an attempt to stay hydrated during the process 😂
I absolutely love that you are sharing technology like this with all the people of the world! You are a true gentleman and scholar! I hope to either make or purchase this paint in the future for personal projects, this is revolutionary!
I wonder how durable the paint is? How long would it survive in direct sunlight and could you put a protective clear coat over it?
The clear coat would have to not interfere with the visible light-reflective properties and also not degrade under the high uv reflective properties.
The more I watch these videos, the more curious I get about how you learned all this, and what you did in the past to know so much...would love to hear the origin story.
I know very little about chemistry and was able to comprehend everything you said. Your communication skills are impeccable.
Great video! I love how you can explain the science without sounding boring as heck or like you're trying to sell me something, and the bits of comedy makes it feel light hearted without taking away from the scientific content!
BTW: that bit with the last coat of paint had such a "Leonard from The Big Bang Theory" energy xD
I've been waiting for this video! Knew it was going to be based off the same concept of nighthawks video. Also, as soon as I saw the box with balls, I remembered the thermal paste episode, and knew where you was going to go with the idea of making different sized nano-particles.
Honestly, Making this stuff on an industrial scale, or making panels of this stuff at scale ( since most regular people don't want to wait 20 minutes between coats, on a 25 coat project, especially if they are painting something fairly large ), wouldn't be the worst business idea, and would have real world uses, especially in the sunnier / warmer climates. I could see not wanting to paint entire walls with this, as in the winter, this paint will help suck the heat out of your house, and throw it into the sky. But in areas that don't get super cold at night, or stay hot all year round, This could drastically cut down cooling costs.
A fun DIY project could be making a decent sized panel, with reflective walls ( like you made in the first video ), and like your original video, connect it to some water cooling, but make it a closed loop system, A radiator could be placed in a hot section of your house ( such as an attic ), or in a shed. Could get cool air into a hot area, for very little cost ( wattage ).
Cooling is one of the largest users of electricity ( and thus, fossil fuels ) in the world. We can heat stuff all day long, with just about anything. Generating heat is fairly simple ( Containing it is the problem ), But generating cold ( moving heat away from a specific area ) is so much more energy intensive, It's almost a cruel joke that thermodynamics is playing on us. Finding any way to cool a specific area, for very little or no energy usage ( continuous usage. Mining, and creating the stuff takes energy though ), Is almost a holy grail achievement. Even if you couldn't "cool" something, but could just offset the heat the sun is dumping on an area would make such a large difference.
These two video's have been by far, one of the most interesting subjects you have talked about on this channel, at least to me. Thanks for all the hard work, research, clear explanations, and time you put into making these videos.
Can't wait to see what you teach us next!
Generating cold is just as energy intensive as heating.
Why do you think that there would be a difference?
In fact in most everyday use generating cold requires less energy.
Using heat pumps for cooling is the norm (with efficiency of 300% or so)
Whereas most heating still is done with burning stuff (efficiency around 90% or so)
well in the winter You could just restrict water flow to the cooling pannels so they wouldn't really be sucking heat from your house, remember this relies on the flow of warmer water.
@@jolioding_2253 depends on your implementation.
A simpler solution than building a water-cooling-loop would be to just paint your roof.
That's what the OP is talking about.
@@Jehty_ in this video he demonstrated just a painted surface bin in the last video he talked about using a water loop and this is an addendum to the last one
@@jolioding_2253 did I say anything different in my comment?....
This is a COOL video. 😎
ba dum tsss
A-yo!
The most chill video I've seen in a while.
Go home Dad, you're drunk.
This is a Dad joke..
Approved.
Something amazing about the internet, if your parents didn't have certain qualities you wish for, you can find aspects of them on UA-cam, like this channel. 10/10. This channel is going to 3+ million subs for sure.
Man you really put an effort to show how good this is. Thank you for helping others, besides that you and your team most enjoy what you do.
For some time I've been looking for paint that does exactly what you and your team just did.
I'll probably try to replicate this and apply it to my house.
Have a wonderful day.
Thanks!
This is insanely impressive, thanks so much for putting this out there!
Another fantastic video, you guys put out the highest quality content. Thank you so much.
I appreciate your channel, how thorough you are with your explanations, and how much time was spent on painting alone.
Thanks!
This is what youtube was created for! I love your content, keep the great work up!!!
I'm awed by the depth of your knowledge and teaching skills. Phenomenal 😃
I'm awed that he drank that crap
I'm facinated to know his back story and what he trained in (there's a big gap between leaning and applying). It's easy to get set down a narrow path in life.
@@jasongooden917 Drank a liter of it for a CT scan, wasn't that bad.
2 Remarks:
A: If you want to ingest some material, you don't just want to make sure that that material itself is safe, but also that there are no contaminants left over from the production that may be harmful in the amounts present.
B: In your centrifuging and drying procedure, the wet BaSO4 is wet with _salt water_. You can get that remaining salt out if you mix it with pure water (distilled or de-ionized water, otherwise you might just exchange salt for limescale) and send it through a second centrifuging pass before drying away the water.
A: Yes, that's why I buy expensive "food-grade lye" even though I can get a case of the same stuff cheaply, sold as drain cleaner. People are amused or confused by the term "food-grade" applied to a toxic substance, which illustrates its actual meaning.
Salt crystals have high albedo too, so may be there is no real need to add the extra step and increase the cost of production.
This was such an interesting test, with a really easy to follow guide. I hope to see this pop up more and more in everyday life. Keep up the great videos! Much love from PA
