Cooling air is tougher. Tougher than heating it.

It’s all about transducers. A rule of thumb is 10% losses per transducer. And turning electric energy to mechanical energy is a huge loss.

Cooling air is tough. That’s the second law of thermodynamics at work.

Never heard of such a thing. Transformers, maybe.

Cooling air is all about compressors and radiator heat exchangers.

Obviously, if your house electric power service is limited to needing 24 hours or longer to recharge your new electric car, you did not plan wisely...

Peltiers.

I never got around to doing the numbers on if peltiers could be used on an ICE exhaust to generate enough power to run a separate set of peltiers as thermoelectric coolers for the car.

Probably too impractical, although, the gub'mint uses propane-heated peltiers to generate power in unattended sensor pods in remote areas.

It's actually the reverse. 1 kW of energy will provide 1 kW of heat, and no more. But that same 1 kW can remove and relocate 10kW (or more) of heat.
