Entropy Engine

We need better info than this. Have you any plans? how did it work exactly.

Regarding the heat pump and references , it seems the temp difference is not enough. Something to do with the Carnot cycle, being the most efficient cycle possible and the DT being low. Its not just heat we need, its temperature differential. Guess you'd have to go through refrigerants and check the DeltaT and work out how efficient the Carnot cycle would be if used.

no, I mean I understand the process. Most call it being "half efficient", I prefer to look at it as you only had half to do the work with to begin with. Because half has to stay there once the other half moves to the other side.

But if you are using 1kw to heat something with 3kw,
you could use that 3 to make 1.5 somewhere else, then come back to the first, or something to the like,
or use an area of a cold to sink the heat to so the process can continue.

@pom, jet nozzles off amazon/alibaba/ebay/?
not your moms garden hose, these have custom shapes, designed to increase the velocity/force
of the water stream, at the expense of flow-rate.
all you need is about a foot and a half of plastic tube to fit in the hole.
once you get your flow-rate and pressure
you can calculate which nozzle you need to get the appropriate height.

it has to be the old style cooler
the new ones have all this extra plastic mess around the hole which screws up the flow
you cant get enough "oomph" to get it back into the top

I think this video shows the reason why a Gadolinium engine would not work.

using pure Gd, if enough heat could be taken off the metal at the end of the cycle,
it would be attracted to the magnetic field. which will begin degradation of its' paramagnetic structure.
This causes a heating process.
when complete, the metal will no longer be attracted to the magnet.

it (and its' heat) can be removed from the field and the heat once again taken off.

Some alloys of Gd have a much better heating effect than the pure metal.
one, in particular, might make a decent demonstration (toy) engine.
Similar in magnitude to the Titinol Engine.

One is a heat source, the other a heat sink.
