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?

You can get “freezers” that will put part of their inside down to 250+c below their surroundings. (Helium cryocoolers)

This is cool! Where do I get one and what’s the power usage?

Semiconductor mfg firesales.

Or if you want to spend the 20+k you can buy from the manufacturer.

Oh power usage… that depends how much you need to cool down, and what setup you have. But usually they’re 3 phase and lots of amps…
