OK but laminating glass with polymer means neither can be easily recycled. That sadly goes for a lot of promising tech :( Recyclability of laminated or composite materials need to be considered carefully when evaluating their environmental impact!
@@bigfootbeliever6985 Yeah, but we still have to go through glass and if our glass ends up being non-recyclable, we need to keep making new glass. Sand is already getting rare as it is, believe it or not, so it would be way more sustainable to just come up with glass that's made from an entirely different source material.
Also, how good is that cut-up glass at insulating the room? And the only time I've seen or heard about broken windows needing to replaced was the rooflights in my grandpa's workshop after some golfball-sized hail smashed right through them. I'm not sure whether the fish-scale glass would survive _that._ So my experience already is that windows - at least in residential buildings - need to be replaced almost never.
Any company producing laminated glass would want to produce laminated glass indefinitely. Which means people/ other businesses must consume more (you know for the revenue of our glass company). It’s even worse if our glass company is listed on a stock market, as it would then need to show constantly high growth (read sales) numbers (a listed company is required by US law to act in the best interests of their shareholders).
@@DarkAngelEU the reason why sand (the kind that is used to make glass) is becoming rare it's because many people don't recycle glass, in which that includes bottles, old windows, glass kitchenware etc. And so if we want to make use of all sand we have, we need to start recycling it. There are an few machines that recycle glass already, they recycle glass by crushing it into a sand.

I'm an Artist (& Biology student), and so see Biomimicry from perhaps a slightly different perspective than, say, an engineer. That said, I've seen a truly extraordinary number of applications of biologically derived design concepts / engineering over the past few years, and the rate of wondrous new Biomimicry developments seems only to be increasing. • The darkest black paints in existence (Black 3.0 boasts over 99.98% visible light absorption) use carbon nanotube "mazes" to capture incoming photons, working exactly the same as the feathers of some bird wings & the integument of some deep sea fish. • Some new colour pigments even rely on nanoscale surface structures, rather than the light absorption/reflection capability of the material, to create the particular hue - functioning in exactly the same way as the scales on a butterflies wings do. • Manufacturers have designed the internal reinforcing structures of objects as varied as cars, shoes & chairs, using the fibrous lattice structure of the interiors of human/bird bones - optimising the ratio of strength to mass to a remarkable degree. • Civil Engineers are planning the road layouts of future cities (& other infrastructure, such as power/data/water/sewer conduits) based on the extremely efficient growth patterns of slime moulds & the adaptive flow dynamics of the human circulatory system. • High-rise buildings have been built with highly energy efficient internal environment controls (heating/cooling) based on the passive structures of termite mounds - tremendously reducing both the running costs & environmental impact of old fashioned air conditioning systems. • Super quiet fan blades designed using the micro-vortice inducing characteristics of an owl's wings/feathers. • Water repellent materials/coatings based on the Superhydrophobic surface of the Lotus leaf. Inversely, a varient of this technology may be used to attract oils, potentially creating capture nets for oil spills. And so, so many more... Along with profound advancements in Nanotechnology & Computer / AI Designs, Biomimicry is moving humanity towards an unparalleled new age of development.
I thought the sweating concrete was going to be a building temperature regulation method. Also, I read a few years ago that they (the infamous they) had discovered the reason Roman concrete was so strong. Salt had corroded the concrete and created a crystaline structure throughout it making it stronger instead of destroying it. Maybe we can engineer a concrete mix that does the same thing with the carbon from co2.
Concrete is an alkaline compound. This alkalinity protects the steel rebar that reinforces concrete in areas under tension; it is called passivation. Carbon dioxide is acidic (especially when dissolved in water which is why the oceans are acidifying). Over time, carbon dioxide in the air at the surface of the concrete diffuses into the concrete, diminishing the protective alkalinity. This process is called carbonation and is considered to threaten the longevity of the steel rebar. This is why there are building design standards that mandate a minimum cover of concrete between the rebar and the exterior surface. The strengthening over time of Roman concretes is due to the presence of pozzolans, a type of naturally occurring silicate minerals that slowly hydrate (combines with water) over time, strengthening the concrete. This is a very different chemical process. Pozzolans are still additives that get used on concrete mixes within certain proportions. Though they keep getting stronger over time, they are slow to gain strength initially, so generally a maximum of 20% by weight is employed so the concrete can be used within a reasonable amount of time, i.e. one doesn't have to wait for 6 months before removing the forms. Concrete mixes are designed to reach their maximum strength within 28 days (for testing purposes as strength gain slows down a lot thereafter). Edit: changed minimum to maximum.
In addition to what I said above, there is an additive for concrete (or for paint) that is designed to use sunlight to combine with air pollutants to 'scrub' the air clean. I saw it specified for an architectural concrete project once. What I also recall is that it would also double the unit cost of the concrete. Too bad that I cannot recall the name of the additive...
The polar bear fur is also hollow tubes that hold more air for insulation and it helps the background color be drawn over the bear to a certain degree.
Love it, you know I came for the glass. That strengthening process sounds amazing. Being done by changing the form/structure and not just adding materials. It sounds great for transportation or larger structures, but for homes I believe it would be better to focus on heat insulation. Windows lose a lot of heat.

Step one, someone needs to put Germany in their place. Everyone needs to understand that Nuclear power is amazing and they shouldn't buy into all the fear propaganda. Lookup Deaths per Terawatt-hour, you'll see part of the greatness that is nuclear power.
Nuclear power is the only viable solution to combat global climate change. Coal is not viable as its a major contributor, so is gas and oil as well. Renewable energy can't meet peak demands or on-time demands, so nuclear is the only real option.
@@matheussanthiago9685 I didn't say Brazil, I sad the former axis, I feel bad for Brazil and for Mexico, and anywhere that the gov'ts are hiding under a rock
Actually, this is a propaganda. Nuclear power is not safe, its numbers look safe just because its use is limited. It is not going to be safe when it become as widespread as coal plants, It is stupid to expect a third world country run a reactor as safe as Germany. There will be more accidents, that is unavoidable.

Question: Can the scaled glass resist multiple punches from a mantis shrimp? I want to see a mantis shrimp in an aquarium without the risk of the tank breaking.
The earlier few studies were published around 2011 and 2014, which means they already didn't work out as someone would have tried those ideas (I hope)?
I actually want to start a channel like this for fun (experiments and explanations) but I am kind of struggling - do you have any tips, sci show? I watch your videos and they are so good.
The polymer shifting is an interesting thought, but I have a slightly better idea. How about instead of expensive silver polymers, we instead use photochromic dye films? You might know them better as Transition lenses, and as they respond specifically to direct and semi-direct UV light, they would have the added benefit of not applying a heat conductive metallic silver material to a window in a hot environment, while also keeping windows fully see-through, just shaded. They would also have the benefit of not significantly reducing your light levels when you're dealing with a shaded window. The hazard of this, and of the polymer coating as well, is that in both cases, you're reducing your incoming light level, which increases the need for relying on electric light, which generates more heat IN the home, to say nothing of the increases in CO2 emissions due to the increased wear on the power grid.
hank, i just want to say you are one of my favriote people lmao. also it took me about a week to realise you were john's brother even though ive been watching crash course for years and have known who you guys for years. i realised it when i was listening to the episode of very really good with kurtis. lol you probably wont see this but if you do, yay lol.
I made home made curtains to help keep my house warm. I made the outside layer out of black fabric to attract the sun's heat and double layered it so it holds the heat in an insulated layer. I live in Minnesota where it gets bitter cold so this helps a lot.
Our town homes are built with such good fire barriers that when one of the units burned down it looked like 1/4 of a pie was sliced out of the building with the other 3 houses unharmed even though they are a part of the same building.
8:55 this reminds me of the way certain glasses crack, in shear patterns instead of straight lines. This is especially visible in igneous glass like obsidian. It It would make sense that the crystal structure is not perfect, and the imperfections often (asfaik) dictate the path stresses are most involved.
I wonder of we could potentially get inspiration from electric eels for generatingnelectric power in a safer, friendly, more affordable, and more efficient way? I mean, we're talking about a potentially 8 foot noodle that can kill an alligator several times it's weight and size with electric shocks (while itself staying safe from said electric shocks).
Why are we not talking about Hempcrete? It is FIREPROOF and is made from a byproduct of hemp production. And those fibers are hollow allowing it to absorb extra humidity and release it when humidity is low. Plus it is anti micro is so it won’t mold or mildew! Why is the world purposely ignoring this amazing product?
Mouth agape. I just love nature and how it reminds humans that nature has already figured it all out. The way nature utilizes and crushes functional design 💪🏽💛💯
4:06 Wait! I was watching a video last year that said that polar bears don't have transparent fur. If you Google it you'll get contradicting responses. Some say it's white others say it's opaque other say it's transparent.
Great info :). At first I thought it's all about like transforming the shape of buildings using green architecture of sort. I do like underground architecture and something of the likes of the Gardens of Babylon, but not a big fan of green walls. I thought that was what the video is about. But it's all about new materials and it's always nice to know new materials available that can be sustainable.
Structural Technician here, how would this fire resistant concrete perform structurally during the fire? If the reinforcing melts the concrete will lose a lot of its strength. We rely on that strength to carry the self weight of the building as well as all of its contents and equipment to the footing. How would this concrete perform that function during the fire and until a crew could enter after the fire to chip away and reinstate that specially reinforced concrete?
There are quite a few developments for passive heating systems, including GAHT, water tanks and solar focusing, and in the right environment organisms themselves are a sufficient heat source (example: winter aquaponics). Our company Arctic Acres manufactures geodesic growing dome greenhouses, alongside an expanding list of features that make them ideal for 365 home growing. We want to create the greenhouse of the future that can be a sustainable solution to growing concerns. Our domes current operate in Nunavut Canada to help sustain entire remote communities, they can withstand 180km/hr winds (that’s a category 2 hurricane), they are 2/3rds more energy efficient than conventional designs, can take 250lbs/sqft of snow load, and look absolutely beautiful. We’re also big fans of SciShow! 🇨🇦💚🤓
Pretty awesome that science is getting finally getting more humble and looking into designs based on nature. I can't wait to see where this thinking goes. The design concepts of God are pretty amazing.
These are all really interesting. I would also be curious to see an investigation into how low-tech solutions could be made better use of. For example, wool and linen both have impressive thermoregulating properties. What might we accomplish by using natural means not just imitating nature, I wonder?
People always investigate synthetic ways, because it's much easier for them to control variables than an all natural one. It might have some high R&D cost, but it usually worth it later on, when they can vary things for a specific task, which are usually much harder to do in its natural counterpart.
@@patrickbueno3279 I get that. I don't think synthetic options should never be explored (I quite enjoy my contact lenses), but I am also curious about what nature already does to meet some of these needs. I believe there is a lot to be gained from stepping back and seeing where we can do less and get a better deal. Sometimes the solution is doing more, sometimes it's doing less. And if we can avoid using resources to make new materials because nature already makes something, and all we'd have to do is change our behavior, then I'd find that fascinating and cool to watch a video about! (And do something with in my real life if it's accessible, which is more likely with something that grows out of the ground than a high tech synthetic thing that just got invented.)
@@ladykarolyn1 natural route means you bioengineered those materials, because nature hate and loves change, that sometimes it's fast to adapt to changes but at the same time it takes time to adapt it into something.

If we want to allow humanity and many other species to continue existing on this planet, maybe we should be forcing those with power to take action.
Step one, someone needs to put Germany in their place. Everyone needs to understand that Nuclear power is amazing and they shouldn't buy into all the fear propaganda. Lookup Deaths per Terawatt-hour, you'll see part of the greatness that is nuclear power.
Nuclear power is the only viable solution to combat global climate change. Coal is not viable as its a major contributor, so is gas and oil as well. Renewable energy can't meet peak demands or on-time demands, so nuclear is the only real option.
Have you noticed something all the former axis powers are the hardest hit of the pandemic
@@cornbreadfedkirkpatrick9647 huuuh... Brazil fought with the ally
@@matheussanthiago9685 I didn't say Brazil, I sad the former axis, I feel bad for Brazil and for Mexico, and anywhere that the gov'ts are hiding under a rock
Actually, this is a propaganda. Nuclear power is not safe, its numbers look safe just because its use is limited. It is not going to be safe when it become as widespread as coal plants, It is stupid to expect a third world country run a reactor as safe as Germany. There will be more accidents, that is unavoidable.
12:13. Wow! That’s a great, but unusual building in Germany! What is it made of again?? Textile based? Awesome!
Biology, Chemistry or Physics going to save the humankind! Sitting in a drywall room and wondering....
Science is a tool for people to use. We need to overthrow capitalism and the profit motive to better our lives and our world.
Don't be fooled into thinking more tech will improve your life; if that was the case, the industrial revolution would have eliminated world hunger.

Question: Can the scaled glass resist multiple punches from a mantis shrimp? I want to see a mantis shrimp in an aquarium without the risk of the tank breaking.
Whats the typical temperature for a building fire?
So much info!
I'll need to watch this in chunks.
Oh, I actually go to Purdue! It's awesome to hear your university referenced in one of these vids :D
Isn’t Purdue synonymous with engineering? That’s what I’ve always heard

This was a really interesting topic
Awesome ideas - have fun getting the construction industry old boys to change to ‘sweating cement’ :P
The earlier few studies were published around 2011 and 2014, which means they already didn't work out as someone would have tried those ideas (I hope)?
I actually want to start a channel like this for fun (experiments and explanations) but I am kind of struggling - do you have any tips, sci show? I watch your videos and they are so good.
The polymer shifting is an interesting thought, but I have a slightly better idea. How about instead of expensive silver polymers, we instead use photochromic dye films? You might know them better as Transition lenses, and as they respond specifically to direct and semi-direct UV light, they would have the added benefit of not applying a heat conductive metallic silver material to a window in a hot environment, while also keeping windows fully see-through, just shaded. They would also have the benefit of not significantly reducing your light levels when you're dealing with a shaded window. The hazard of this, and of the polymer coating as well, is that in both cases, you're reducing your incoming light level, which increases the need for relying on electric light, which generates more heat IN the home, to say nothing of the increases in CO2 emissions due to the increased wear on the power grid.
Good to see hank green in a new UA-cam channel ,kind of surprised.my fav science host in UA-cam
hank, i just want to say you are one of my favriote people lmao. also it took me about a week to realise you were john's brother even though ive been watching crash course for years and have known who you guys for years. i realised it when i was listening to the episode of very really good with kurtis. lol you probably wont see this but if you do, yay lol.
That "yay" made me very happy. Thank you
I made home made curtains to help keep my house warm. I made the outside layer out of black fabric to attract the sun's heat and double layered it so it holds the heat in an insulated layer. I live in Minnesota where it gets bitter cold so this helps a lot.
It turned grey over time so it probably doesn't work as well as when I made it 20 years ago but they still work well enough to not waste and replace.
Our town homes are built with such good fire barriers that when one of the units burned down it looked like 1/4 of a pie was sliced out of the building with the other 3 houses unharmed even though they are a part of the same building.
Another Great Vid
Neat analysis & summary of all this information! Thanks for uploading!
8:55 this reminds me of the way certain glasses crack, in shear patterns instead of straight lines. This is especially visible in igneous glass like obsidian. It It would make sense that the crystal structure is not perfect, and the imperfections often (asfaik) dictate the path stresses are most involved.
Is there an episode like this on accessible architecture? Cause I would love to see what that would look like, especially in this context
I wonder of we could potentially get inspiration from electric eels for generatingnelectric power in a safer, friendly, more affordable, and more efficient way? I mean, we're talking about a potentially 8 foot noodle that can kill an alligator several times it's weight and size with electric shocks (while itself staying safe from said electric shocks).
Why are we not talking about Hempcrete? It is FIREPROOF and is made from a byproduct of hemp production. And those fibers are hollow allowing it to absorb extra humidity and release it when humidity is low. Plus it is anti micro is so it won’t mold or mildew! Why is the world purposely ignoring this amazing product?
Mouth agape. I just love nature and how it reminds humans that nature has already figured it all out. The way nature utilizes and crushes functional design 💪🏽💛💯
4:06 Wait! I was watching a video last year that said that polar bears don't have transparent fur. If you Google it you'll get contradicting responses. Some say it's white others say it's opaque other say it's transparent.
Well that's alot of improvements, that's pretty cool
Always interesting, thank you.
By starts bill gates could reduce his carbon footprint🙃
What about Hempcrete guys?! It’s a flipping miracle!
Great info :). At first I thought it's all about like transforming the shape of buildings using green architecture of sort. I do like underground architecture and something of the likes of the Gardens of Babylon, but not a big fan of green walls. I thought that was what the video is about. But it's all about new materials and it's always nice to know new materials available that can be sustainable.
Love it! Great material science and smart materials to build better stuff for people!
Love this show
I Love biology! Thanks for the cool video!
You did not say how the last one was based on fish, or what goes on in fish
Structural Technician here, how would this fire resistant concrete perform structurally during the fire? If the reinforcing melts the concrete will lose a lot of its strength. We rely on that strength to carry the self weight of the building as well as all of its contents and equipment to the footing. How would this concrete perform that function during the fire and until a crew could enter after the fire to chip away and reinstate that specially reinforced concrete?
if i remember right there was a similar design to the mantis shrimp inspired cement that looked to the patterns found in conch shell structures
As a student architect this is actually fascinating

just a small point, we have been using thermal "walls" or thermal massing for literally 100s of years. its not a 20th century thing.
Y'all I forgot homeostasis exists and I wondered "What could he be talking about? That sound cool!" And then I saw that and actually laughed.
This is amazing, I wonder what we'll do next.
Depending on how well we advance in stripping wood of pigment we could theoretically make fully wooden windows instead of glass ones...
There are quite a few developments for passive heating systems, including GAHT, water tanks and solar focusing, and in the right environment organisms themselves are a sufficient heat source (example: winter aquaponics).
Our company Arctic Acres manufactures geodesic growing dome greenhouses, alongside an expanding list of features that make them ideal for 365 home growing. We want to create the greenhouse of the future that can be a sustainable solution to growing concerns.
Our domes current operate in Nunavut Canada to help sustain entire remote communities, they can withstand 180km/hr winds (that’s a category 2 hurricane), they are 2/3rds more energy efficient than conventional designs, can take 250lbs/sqft of snow load, and look absolutely beautiful.

Just another reason to protect nature more.
So much tech innovation we can gain from them.
I love how bill gates wrote a book about that when he does stuff like import tons of sand from the Caribbean to his house on a lake

Cutting edge science 😂
That fish scale glass is intentionally less stiff in order to improve toughness. I'm not sure it's actually stronger in technical terms?
Pretty awesome that science is getting finally getting more humble and looking into designs based on nature. I can't wait to see where this thinking goes. The design concepts of God are pretty amazing.
As are the convolutions of the Sacred DNA!!
These are all really interesting. I would also be curious to see an investigation into how low-tech solutions could be made better use of. For example, wool and linen both have impressive thermoregulating properties. What might we accomplish by using natural means not just imitating nature, I wonder?
People always investigate synthetic ways, because it's much easier for them to control variables than an all natural one. It might have some high R&D cost, but it usually worth it later on, when they can vary things for a specific task, which are usually much harder to do in its natural counterpart.
@@patrickbueno3279 I get that. I don't think synthetic options should never be explored (I quite enjoy my contact lenses), but I am also curious about what nature already does to meet some of these needs. I believe there is a lot to be gained from stepping back and seeing where we can do less and get a better deal. Sometimes the solution is doing more, sometimes it's doing less. And if we can avoid using resources to make new materials because nature already makes something, and all we'd have to do is change our behavior, then I'd find that fascinating and cool to watch a video about! (And do something with in my real life if it's accessible, which is more likely with something that grows out of the ground than a high tech synthetic thing that just got invented.)
@@ladykarolyn1 natural route means you bioengineered those materials, because nature hate and loves change, that sometimes it's fast to adapt to changes but at the same time it takes time to adapt it into something.
I don't understand, how do you 3d print cement? It would've been great to see an example of the actual cement
having fiber expand and contract on a daily cycle in a plastic like matrix or in glass doesn't sound like a great combination for durability?
Unfortunately those seem more expensive to make so we are going to have problems with societal buy in.
Dude! That "polar bear inspired heating material" would be absolutely STELLAR AND PERFECT for the living quarters on Mars once we actually make it there and house ppl for 2 years at a time.. also, I sure hope that the SECOND team going in don't encounter a bloody murder site where Team 1 was living. Good idea for a story or a game oh wait, Doom... Lol
