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? (lemmy.dbzer0.com)

Flash freezing things is a thing.

Well, it does exist, it's called laser cooling, but it's only if you want to have things really cold

You just have to rotate the food the other way in the microwave like in Steins;Gate.

Call it Macrowave!

There is! It's called a blast chiller and just takes a dumby amount of energy proportional the amount of energy removed from the food. It's easier to add than subtract.

Probably not. Nice choice of pic to illustrate the need, though 😄

It's a lot easier to generate heat from electricity than to transfer them out. Closest bet would be just blasting cold air but heat transfer will be slow so it's still quite limited.
