Blast freezer. It’s about as close as we’ll get any time soon. Not an affiliate or anything, just googled and found this bugger (about microwave sized).

I present the Macro Wave!
It’s called a freezer and it just takes a bit longer.

They trial’d something similar on the snowpeircer train instead of treats like ice cream for good behaviour they froze your arm off for being naughty lol
It’s a good job they didn’t have that when I was at school because I’d be just a head and torso now lol
Push heat into something is easier than pull heat out of something
That’s not how a microwave works.
Make something vibrate fast easier than make something vibrate slower
Pushing energy into a thing is easier than stopping it
It pretty much is. It bathes your food in intense radio waves that get absorbed and turned into heat.
Removing heat energy is what your freezer does, by transferring it outside of the freezer box.
You can’t just remove heat by adding electromagnetic energy. Absorbing energy from the electromagnetic radiation makes heat.
Edit: whelp, TIL
If you’re very careful you can remove heat with electromagnetic energy.
Think of heat like someone on a rope swing, and electromagnetic energy as a push.
If you time, and angle your pushes very carefully you can slow the person on the swing. But it’s much easier to speed them up. Same with electromagnetic energy.
The magnetocaloric effect can do this. Instead of the target absorbing energy, the magnet does. The magnet heats up and the target cools.
You can’t just remove heat by adding electromagnetic energy.
Except that you can.

Flash freezing is how frozen foods are made.
Refrigerator
There is a drink chiller that chills drinks in about a minute. You could use the same idea for other things.
The Chill-O-Matic is smaller, cheaper and probably easier to clean as it doesn’t seem to have tubing.
The design of that machine in your link is a lot of overkill for something simple.
i would think not. unless waves can be tuned to cancel out background radiation, but that would only stop it from heating up more.
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.
This is a bit like asking if we could build a flashlight that emits a beam of darkness I think
That’s a fog machine
Very much so, and equally possible in theory (interference patterns with light exist, light cancellation could work somewhat like noise cancelling) but also equally impossible to do at anything much above an atomic scale.
I have that device
It is my phone
It’s not. A device that rapidly cools things down placed inside it isn’t implausible. He’s not asking for a beam of absence, he’s asking for an enclosed space that subtracts heat.
I do believe that’s a freezer.
Yes or one of those weird ice cream things that has an extremely cold surface, or one of those things where you roll it in ice water or a million machines. “Machine that makes things cold” isn’t sci fi.
heat pump
Shooting something with “cold energy beams” is an anti-microwave
We aren’t talking about machines to make things cold, I was asked if we could make microwaves that make stuff cold
deleted by creator
Well, it does exist, it’s called laser cooling, but it’s only if you want to have things really cold
Given how much about science we still have to learn, I would say it is a distinct possibility. If you want something cheap and easy to use like a microwave to do this though, I highly doubt we’d see that possible for the next 30-40 years at minimum.
