All you need to do, is figure out a way to use electro magnetic radiation to slow down particles.
It’s just a small technical challenge.
From these 2 sentences, I have written a 52 pages PowerPoint presentation to get funds from Wall Street.
I expect to find ~$2 bn.
See you in jail!
Cold doesn’t exist, it is merely the absence of heat. Easier to insert heat than remove it, same reason why you can put on warmer clothes in the winter, but you can’t make yourself cold in the summer.
a can of soda can cool faster in the freezer for ~30 min.
some people suggest adding an insulated sleeve.
i also use freezer to cool down coffee quickly.
< deleted. pls find info on fb/yt > …There’s something called blast freezer, which is basically a freezer with fans inside, like what convection ovens have. It cools down food much faster than a standard freezer.
The problem is that cold is merely the absence of heat, you can’t inject cold into something or generate cold, because there is no such thing as cold. It’s kind of like how we can make a light bulb, but we can’t make a dark bulb.
Maybe we could start manufacturing mini black holes to build the dark bulbs!
We have that, it’s called a fridge, and then there’s a freezer for making things frozen.
But a fridge is the opposite of an oven. Some kind of flash freezing would be like the unmicrowave.
The reason we shrink heating devices down but not cooling devices is a combined consequence of economics and the laws of thermodynamics.
First an analogy: Making a boat that moves downstream a river is easy. Take any buoyant material like a log or a branch and drop it in water. Presto, you’ve got a mode of transportation of any size. Want to go upstream? Now you need motors to fight the current. Putting a motor on a large piece of wood, (a boat) is economically viable. Putting one on thousands of sticks? Ain’t nobody got time for that.
As a consequence of the laws of thermodynamics, the the universe naturally converts all potential energy (fuel, electricity) into heat. The universe will do this basically on its own, over time, constantly. This is called entropy.
Doing the reverse, taking heat and putting it back into potential energy, i.e. cooling, is difficult. You basically have to pay a price to the universe in some other way, kind of like how a motorboat has to push more water downstream than the current would have naturally moved on it’s own. This is what heat pumps (AC, fridge) do. Heat pumps put some of that heat back into potential energy, in exchange for also releasing potential energy into heat… The trick here is to do these two things in different places. The fridge’s motor converts some electrical energy into heat in exchange for being able to move some of the heat in the fridge outside of the fridge. The consequence of this is that the room the fridge is in is now hotter. Mostly because you took the heat in the fridge and moved it into the room, but also because the fridge’s motor also added some MORE heat to the room in the process in order to fight entropy. So to actually make this useful, you need to insulate what you are cooling (or it will just get warm again, warmer than it was before, because you added heat to the room), and you also want to dispose of the heat in the room. So you pump that out into the atmosphere…
Anyway, long story short, you need insulation, refrigerant, motors, heat changers, lots of power to fight the universe’s tendency to spread heat everywhere. Technically you could miniaturize these things, but they become less efficient as you shrink them down, to the point where things smaller than a fridge are just not practical to make compared to the benefit you get from having them.
Making small heating devices is easy. You don’t need to fight the universe. You just need an apparatus that will “go with the flow”.
