Smart people, why hasn't someone invented a machine similar to the microwave, but for freezing food instead of warming food? Seems like it would make a lot of money.
I thought flash freezing was really dangerous?

They have those on Chopped.

Seems like "making cold" is a lot harder than "making heat". You can't actually make cold. You have to remove heat from some substance. In fridges, it's the air that is cold. And it takes time for air to make the stuff you put in it cold. And if you made the air very cold to speed it up, it would actually be super dangerous. I'm REALLY not sure about the science, or if there could be good ways to make it work, just pointing out that's it's different. Microwave ovens expand energy to create heat, but expanding energy to REMOVE heat would be a lot more complicated.

Adding heat is a lot easier than taking heat out of something
If you could cool something so fast people would make super PCs and not reverse microwaves
Microwaves create heat by causing water molecules to vibrate so rapidly they generate heat. This principle cannot be applied to removing heat. The first rule of thermodynamics states energy cannot be destroyed. Heat is energy. To cool something you must transfer the heat energy from it. Microwaves channel electrical energy into making the water molecules vivbrate and thus transfew the electrical energy into heat. This does not apply to removing energy.
There was a movie based on a true story about an invented that want to make the greatest invetion to win a really important science convention. His device was, in fact, a reverse microwave.
Look it up. Amazing film, it's called Haggard. Very important, heavy issues tackled.
Pic absolutely related. That's the flick.

>Haggard: The Movie is a 2003 American independent comedy film based on the true story of how reality television personality Ryan Dunn's promiscuous girlfriend cheated on him. The film was financed, directed and produced by Bam Margera.
I wish I could push a button and make a hand holding a hammer pop out of your monitor and hit you in the head.

excellent film

Freezing too quickly can damage food.
You could freeze something quickly with liquid hydrogen or something.
I imagine something like that already exists.
