You must never encourage delusional monomania ...
you have a welding problem, barda, on your demonstrator? come back when it will weld.

Moreover, with the same amount of heat in the delta, more energy is recovered from the cold than from the heat. with 1 kg of liquid nitrogen one can theoretically recover 240WH from electrical energy
I have a little trouble with that ... the energy goes from hot to cold not the opposite, right? how do you get energy from the cold?
the principle is to use mechanical energy to refrigerate until liquefaction.
The reverse process (heat recovery from the cryogenic liquid) releases 1000 gas volumes larger than the liquid (approximately), and these gases can be expanded in turbines or air motors.
Eric speaks in theory ... so which equations?
We saw above, thatin theoryyou can make a perpetual movement with compressed air ...
And 0.24 kWh is a rather low energy value ...

It will not hurry to the gate.
