My tortured brain having found his fellow beings here down, I make you by one of my cogitations:
Why has no one ever tried to couple a heat pump with a stirling engine?
Theoretically even with yield losses we should be able to do something good no?
The stirling engine works from a difference in temperature and can power an electric motor ...
Pac she knows how to provide and cold and hot ... and theoretically produces more than she consumes ...
That could make a nice loop ... but would it work?
Go there, linke me!
Trick it's on ... trick I do not know ...
You are not the first to think about it
Alas ... it does not work
The heat pump "produces" more than it consumes, but with a small temperature difference between the hot side and the cold side.
The more it is asked for a large temperature difference, the more the COP falls.
The Stirling engine, on the other hand, has an excellent performance when the temperature difference between hot and cold sources is important.
The lower the temperature difference, the lower the yield ...
Regardless of the setting, the product of the pump COP by Stirling efficiency will remain below 1.

Even better, recover the heat of the water by making ice that we abandon !!
Impossible in reality because studied by Carnot from 1824:

So no miracle, and claims heat pumps are misleading in their vocabulary!
