What's the use case for this?

Cooling things down to room temperature still seems best accomplished via a simple fan...

Generating power from those kinds of systems is still best done with steam based systems...

Thermo Electric Peltier coolers (TECs) can be used for refrigeration. They aren't very cost effective though and are less efficient than condenser/evaporator coolers.

I first stumbled across TEC chips here: https://www.youtube.com/watch?v=UBNFrRsJJ08

People normally use a TEC for cooling things to below room temperature.

The material in the paper appears to only be useful for cooling things from high temperatures down to room temperature...

Which would be done rather efficiently by a simple fan...
