About 15 years ago, there was a new technology for heat pipes used on computer mainboards to keep the northbridge chipset and power transformers passively cooled. They used a sealed pipe with some kind of liquid inside. I think the warmed liquid changed phase to a gas, spread out to far end of heat pipe, cooled, condensed, flowed back to replace the void of newly formed gas. This moved heat to the far end of the heat pipe so much faster than conduction that you could literally put a blow torch on one end and still hold the other end as the heat was also released from the pipe very quickly, so it shed all heat before reaching your hand. The pipes were some alloys, possibly ceramic with copper nanoparticles, or a metal alloy. Not sure what liquid was used. Not sure, but I think it was phase changing liquid/gas.
Research on phase change materials and combining that with the new capabilities of heat-to-electricity (TEGs) should produce some interesting results.
If the phase change materials can be handled more easily and safely while storing more heat than a huge molten salt pile, then it's a win.
If they can deliver the heat to the TEGs as well as or better than the existing molten salts, then that's a win.
And finally, if there's a way to convert, directly using the phase change quality of those materials, to electricity, skipping the TEG altogether, then it's a huge WIN.
This is a great area for research because we produce so much waste heat, and we now know how to collect solar heat to feed that kind of process.
I could listen to you all day
Hey Rob! The National Institute of Materials in Japan talks about Titanium Nitride nanoparticles on their UA-cam channel that seem to be even better than copper at performing this phase change. They demonstrate this stuff apparently making steam under sunlight while the liquid remains at room temperature. Do check it out if it sparks any ideas!
are you like studying to be a physicist ? you know a lot of cool stuff
@@coatMVs Thank you very much, I actually am doing just that!
I think a water heater using this technology would be a great addition to the channel
I have recently had installed a water heater using phase change materials. "Fischer future heat", not sure what materials they use though. Of course I use it in conjunction with my solar panels. Seems to work ok so far.
@robertmurraysmith great idea to show us the video you are referring to. Ten points
When talking about water & nanoparticles I remember that 100% pure water can go well below 0c & stay liquid. As soon as nanoparticles are added those create nucliation points for the phase change to a solid to begin / occur. With those impurities already present in water it will freeze normally at 0c.
Heats of reactions aren't a production or absorption of energy per say, merely a change in temperature due to the change in the heat capacity of materials when they form new bonds, the energy that they had to start with is the same (in an insulated system). But once they get hotter or colder, the temperature difference with the environment results in a spontaneous flow of energy until the temperature becomes uniform, giving the illusion that energy was produced or consumed, but it hasn't, it merely redistributed because of a change in heat capacities. It's a bit like the spinning ice skater who spins faster when they pull in their arms, the kinetic energy they had was the same, but because their moment of inertia changed and the momentum has to be conserved, the result was spinning faster without adding energy.
I'm really interested in this type of technology, I've been looking at products from a company based in Scotland with all the UK changes around heat etc. Would love to see how they function internally with a DIY project!
I have spent many years studying phase change materials doing renewable energy research.
While right just this instant, I'm not conducting any physical/practical studies, I'm still reading up on the subject, until I can get to the point where I can resume physical/practical studies, because I have read some information that strongly suggests that there are some super deep depth phase change chemicals people have simply never been looking into, which are so rich in energy density that they can literally out perform lithium ion batteries.
Admittedly, this study is somewhat 'under wraps', at the moment, but, should it become a thing, you can expect that many people will immediately try to copy my work.
Therefore, until I get to the point I can bring this into actual production, I won't be releasing anything on it.
Wow. You are a treasure. Thank you. Be happy.
We have those hand warmer packs where you snap a metal popper to change the liquid to a solid which releases heat. I wonder if there's a material that could change phase when exposed to sunlight, and then when reversed, instead of releasing heat it releases electrical energy. If something like that existed you'd essentially have a combined solar panel and battery.
I have vaporized and condensed M-state Ormus Gold and Silver onto a 90% silver coin without ever melting that coin...max temp was around 450F. Not high enough to melt gold or silver and much less vaporize either. Go figure :)
David Hudson told me that I should consider the/an acetate...yup...better than a sacrifice of silver for sure!
Peace and love to you all ~~
I actually said that on the sand battery storage already 🤣
Making a very efficient thermal energy store battery would be really interesting, indeed. Seems to me, an axial flux generator/s driven by wind, to produce heat for a very efficient thermal energy store battery, on a scale to meet all of a home owners needs, by a home owner,/ RMS video follower, ought be achievable, and cost effective. .
So wouldn't a sand battery be more effective if you converted the regulator sand into its smaller nan😢o particles ?
Geometry has a major affect on the properties of materials
Take carbon for example, as graphite it's not very good at conducting heat, compare that to Graphene and it's now absolutely amazing at conducting heat
Hope this helps 😁
So yes it would be probably a better version of sand battery more than likely...
It's a metal so has very good heat capacity and copper specifically also has good heat conductivity. And moreover copper nanoparticle enjoy transferring heat to adjacent materials more than usual. This could probably be used together with graphite insulation tile separated with ceramics from the copper nanoparticles to create a very efficient heat storage device.
Expensive as all heck which would make these A. Target for copper thieves and B. Just better to use small amounts of copper NPs in a sand based thermal battery
What scale of production of copper nanoparticles would be required to produce a functional home sized battery that could be solar charged?
Can you do one with generating nanobubbles with Generation and Stability of Size-Adjustable Bulk Nanobubbles using electrostatics? The paper is called Massive generation of metastable bulk nanobubbles in water by external electric fields.
I heard that there is a company in the Netherlands that makes something like that sand energy storage. I think it's called Nestor
Don't forget there's also Bose-Einstein condensates. Also supercritical fluids but I guess that's not really a phase so much as a continuum of states between phases.
I would say there are 5 states of matter the brittle glass phase like state, I call it vitreus. Because at a sufficient low temperature everything gets in that brittle state like structure I'm surprised no one didn't recognize this observation. 🤔
Prooft me wrong the temperature doesn't change either until the get in the brittle state too
Open wind capture real-estate Who says all fences need to be ridged, put them on swivel joint pulley to gear to generator/motor, mabe gear it for higher windspeeds
great content
This is my first ever comment and I shall keep it simple but there is some fundamental questions I had about the nanoparticles part. Given they are easy to make, but how to keep a check on their consistency under different weather conditions as we have here in India? Additionally, when you say that copper nps can eat up light too and store it in heat form, then would that heat be in the same ir wavelengths? Your work seems commendable, sir.
I just put my parabolic antena for sale just before you post this video. What are the chances! I can't build anything where I am sadly. Nice video.
that is a coincidence for sure lol
Isn't the Carbon Scoring from Running a Current through treated paper also a way to make Carbon Nanoparticles?
So the copper nanoparticles in your videos would turn black in the sunlight or is there a different process that turnes them black?
As always, thanks for the video! Does this only work to improve the heat conversion of sunlight, or would it also make a liquid heat up faster in general?
it improves heat transfer in general
pcm is ok in theory, but methanol can become practical :)
Rob! Don't you think it is time for a flying car? Surely all the knowledge inside your head should be able to figure out an affordable flying car. Like right now the batteries don't last long enough (I imagine) - but is there some way to re-charge capacitors using the windspeed created from both the engine forward motion but also from gravity - or creating water and then dropping it, or using graphite impregnated shell...or drop the shell of the plane or use it for fuel in some way - chemicals on one side of the plane creating a potential with regard to the other side. I am quite tired of waiting for someone to invent a flying car. Surely you also want this to be done in your lifetime!
I’ve cracked it
try changing 2 ltrs of hydrogen and 1 ltr of oxygen into water at room temp. that would be a phase change..............(impossible) no hydrogen in water...........
H2O, TWO ATOMS OF HYDROGEN AND ONE OF OXYGEN, THAT IS WATER.
If you mix those and expect to function, it will be pretty slow, the reaction emits a ton of energy (literally this is rocket fuel) either as a big beautifull ball of fire or as electricity in your garden variety fuel cell.
That's not a phase change, that's a chemical reaction.
