How Solid State Cooling Could Change Everything. Use code 50UNDECIDED to get 50% OFF plus free shipping on your first Factor box at https://bit.ly/3BRkS87! I talk about heat pumps a lot. They really are the most energy efficient way to heat and cool things, but the study of caloric cooling represents the potential for a new, solid-state-esque approach to managing heat. Yup, solid state. That comes with the possibility of achieving significantly higher efficiencies without refrigerants. Caloric cooling holds massive implications for the way we cool our homes, our vehicles, and maybe even ourselves. So, how does it all work? And why does it have the potential to completely change climate control?

E in vs E/t out…. Component recovery RRR X 7+B people = a need for multiple refrigeration systems tech delivery and on-going service. The Freon issue with Ozone depletion is 85%+ aircraft fuel emissions reaching the stratosphere, not the ground based systems … consider Why and When 'free air miles' was introduced … hint…after a Globe conference of scientists determined it was the jets constant polar migration of fuel chemistry …why bother the public with facts…to seduce vs reduce the jet-setter economy…anyway…a gaseous rant…. sure like the idea of a solidstate coolant system thats expandable with modules or retrofits… Good explanation of some new techniques.. Thanks
There’s a YouTube video where someone made a refrigerator out of rubber bands. It worked poorly but it worked.
i've seen a video of someone making a refrigerator from rubber bands and carboard using electrocaloric process.
This tech has been around for half a century and has changed very little due to the physical limitations of the device. It is only used where there is allready an extreme temperature difference (think rocket engines) or other extreme limiting factors where refridgerants take up too much space or are exposed to elements that make them unsuitable. The fact is that the thermoelectric effect will NEVER make sense in the consumer space, because it simply isn't efficient enough.
On a side note, people putting this forward tend to talk about how cool and elegant it is to harness the power of natural phenomenon to do heating and cooling. Well, I think that the fact we can create an extremely efficient heat pump using nothing more than phase changes and simple pumps is far more elegant than the thermoelectric effect. It's incredible that we can bend the rules that far with nothing more than a few meters of pipe and a pump. Can't get much more elegant than that.
The biggest problem here is actually transferring the heat. In a classic refrigerator or an air conditioner the heat is transferred by the refrigerant (the cooling agent). In a solid state air conditioner how the heat is supposed to be transferred out of the room when a cooled NiTi wire absorbs the heat of the room?
I don't understand why this should be more efficient? what does it mean? will it consume less power at the same cooling rate? But what about the laws of physics, and specifically the law of conservation of energy?
Hey mention of thermocouple cooling? Not efficient, but worth 30sec of consideration
I now have active plans to DIY a heat pump using this principle.
As a technician with years of experience in commercial refrigeration, I've seen countless 'breakthrough' technologies that overpromise and underdeliver. These so-called space-age materials often claim to revolutionize cooling cycles but end up being overly complicated, requiring controlled, lab-like environments for maintenance. We already have compressorless technology in RVs and mini-fridges, and this feels like another push for investors to fund research on solutions to problems that don’t really exist. In contrast, the most practical and proven innovation I’ve seen is Daikin's bearingless turbines in their magnetic lift chillers. By eliminating the need for bearings and reducing parasitic loss, this technology is ready for real-world applications today.
Omg Matt my head hurts 😅 great video even tho I had no idea what you were telling me 😂😂😂
This is facinating….It'll interesting to see how popular it gets….I know in the EU it'll be prohibited from 2027 to sell heat pumps/ air con with the current refrigerants, R32 and 410A, if mermory serves, they'll be propane (R290) with a GWP of 3…..which although still worse, I'd imagine will be seen as negligible !
If you are reasonably fit, a foot pump will never let you down, at a fraction of the cost.
So i saw the "thing" at 14:22 and thought:
Maybe the best design would be like a double-ring-system, where the two rings are connected with elastomeric compounds, but the inner ring can be adjusted to get very slightly off-center to create a stretch for the material on one side and a chill site on the other side. You then can use a 2 way system to exchange the heat to the environment via a fluid and to exchange the less-heat to the chamber which has to be cooled.
But i think there would be a problem with the separation of the 2 sides because the 2 rings are changing the sides constantly. So you probably end up with the same problems, a Wankel or Liquid Piston Engine encountered during its development.
didnt #CodysLab do a video on this years ago? the chemical aspect and making it that is
Looks like my PC might finally stop sounding like it’s ready for takeoff. The future is looking cooler already! ❄

We can already get away from HFCs by using very high pressure supercritical CO2 systems. But they are EXPENSIVE and carry additional risk to work on.
As an hvac technician for 20 years….HEAT PUMPS SUCK. A compressor running all year is a great idea 🙄. I suggest a good old simple gas furnace. I replace a 40+ year old furnaces all the time. I guarantee nobody will ever get that out of a heat pump
If you can improve today's refrigerator compressors…. I am all for it.
You said "Muscle Strand" and I immediately thought of Jaeger's from Pacific Rim!!

Wait until solid state food. It'll change everything.
Elastochloric material could be merged into heatpipes to act as a heat-powered heatpump engine to remove compressor, noise, hence electricity from the 2-radiator loop.
