247Solar has announced major milestones in the commercialisation of its next-generation solar thermal electric generating technology, which offers commercial/industrial as well as grid-sca…
Scientists in the United States has developed a new photovoltaic-thermal system design that utilizes parallel water pipes as a cooling system to reduce the operating temperature of photovoltaic panels. The waste heat generated by this process is then used to generate domestic hot water.

The new My Skin Track UV device is the world’s first battery-free wearable electronic gadget to measure UV exposure. Developed by Roche-Posay and L’Oréal, its parent company.
This gadget can tell you when you’re about to get sunburned
Ditch your old-school bottle of sunscreen, the future of sun protection has arrived. First came UPF clothing, then the sunscreen shower. Now there’s this cutting-edge UV device, which can be clippe…
You can already get heated cushions, not sure about pillows though.

Time will tell….. “Physicists at the University of Zurich have developed a deceptively simple device that allows heat to flow temporarily from a cold object to a warm object without an external power supply.”
The Second Law of Thermodynamics is bent but not broken.
Don’t hold your breath. If this new theory pans out, quantum demons might someday power our air conditioners and refrigerators, saving you electricity and cheating the current laws of physics at the same time.
Argonne researchers posit way to locally circumvent Second Law of Thermodynamics | Argonne National Laboratory
But researchers with the U.S. Department of Energy’s (DOE’s) Argonne National Laboratory announced recently that they may have discovered a little loophole in this famous maxim.
nice idea, but the jury is still out on if it is the reason time goes one way only, everything else points to it being able to go both ways, just not for urr, us.
No, Thermodynamics Does Not Explain Our Perceived Arrow Of Time
Bet they didn’t realise at the time that the idea of the second law was what gives time a forward only direction. ie…”Entropy is one of the few quantities in the physical sciences that require a particular direction for time, sometimes called an arrow of time. As one goes “forward” in time, the second law of thermodynamics says, the entropy of an isolated system can increase, but not decrease.”

Professor Mike Merrifield does a good job of explaining what this idea entails. The second law is the interesting one though, because it has various formulations as it was thought up before people understood entropy. Yes you need to add energy to a system in order to make colder things hotter. With regards to entropy, Lord Kelvin states that you can’t turn heat directly into useful energy. Seems obvious really but its an idea that has stood the test of time and likely won’t be disproven.

“Heat causes the blood vessels to dilate, bringing more blood to an area, which brings oxygen, protein and nutrients – helping muscles and joints become more flexible and move more freely. This process also helps repair damaged tissue so may aid the healing process.”

Convert your existing bed into a Dual Zone Climate Controlled Self-Making Bed using your current bed and bedding. SmartDuvet will have you sleeping in perfect comfort every night without having to worry about making the bed in the morning.
Thermal solar modules have been around for several decades now.

This is a fabulous idea. You can power and heat your home at the same time.
There are hybrid solar panels that can generate heat and electric energy.
Solar panels produce immense amounts of waste heat that can be harvested into clean energy.
and this for lunch
and this for love
Seen this? Looks pretty good. Anyone used one yet?

There’s an app for that already.
none are electrical but they seem to work as I have seen good reviews online
FYI
Or just buy the fan so you can use any sheets. these look great tbh.
Old idea but good for oldies. Just use electric blanket not a mattress, and buy pillows online, there are a few choices.
You can already get heated cushions, not sure about pillows though.
Already exists, don’t have one though.
nice idea, it exists, not sure if doctors would say it was wise for guys who want kids one day though(?)
IS the Universe a closed system? How could you disprove that it isn’t? Too many assumptions in order to KNOW the second law is ALWAYS right (for me).

Stinky for your co-workers but they have them in white too.
Great idea, just looked, you can get them on Wish
tried the ooler system?

This has been done. Not sure where you can buy them though.
