Finally! Now we can have an air conditioner that does not require a pipe to blow the hot air outside. Like truly mobile unit.

Unfortunately we'll always need the pipe to blow air outside. The heat has to go somewhere. Even with this invention, if they're converting heat to electricity, they will have to release at least as much heat as they converted to electricity.

That’s thermodynamically impossible.
Why? You could theoretically take out energy from the room in the form of electricity
“It is impossible to devise a cyclically operating device, the sole effect of which is to absorb energy in the form of heat from a single thermal reservoir and to deliver an equivalent amount of work.”

#29So I can use electricity to mine cryptocurrency and convert the excess heat back to electricity? I wonder how efficient such a thing would be.
Re: Cheap material converts heat to electricity
#30Current peltier chips are barely a few percent efficient, break easily and require high temperature differentials. They're used in stove-top fans and RTGs. The latter should be Sterling engines to be ignorant mind. I don't doubt there are some interesting things to be accomplished by shaping the flow of heat conduction but I sincerely doubt it'll be energy generation directly. Thermodynamics isn't something you can j…
