Some years back, I first came across an amazing phenomenon -- the Ranque Hilsch vortex. My physics is below pathetic level, but this concept I find really exciting.
An example they give for entropy and time in any video lecture...water poured out of a glass and water going back into the glass...
For a bath, I mix a bit of steaming hot water with some cold water....if I could reverse the process and get a little hot water and a little cold water from tepid water, how amazing that would be!
That's how this phenomenon is. It's amazing. Of course it's not the same, but the result says that's what has happened doesn't it?
I have seen that it is used for spot cooling but never for larger volumes.
Is it truly not possible to do this on larger scale to have eco friendly air conditioning? or is it just that no one has tried it out yet?
