Probably a stupid question, but will we ever have something like a microwave to make things cold? Is there a reason this can’t exist?

N.B. maximize air content while minimising air movement and therefore convection. Otherwise you could just have cavities in your walls for maximum air.

Correct. Convection would just annihilate your insulating effect
