Not the same distance, nor speed. Gas is way less dense. It is just receding from the remaining gas and accelerating the leading/escaping gas. Doing work.

The force inside a cylinder is pressure times area. Pressure is P=∆TCvM. That equation doesn't have Watts,axel in it anywhere.

"P=∆TCvM"

Should have been:
PV=MRT
And:
P1•V1/T1=P2•V2/T2
And:
Q=∆TCvM
None of those have 'Watts output to an axle'. Watts output to an axle could be in 'n'. All of them respond to adiabatic with a piston, no further connection needed.

n=W/Qb
W could be Watts output or Watts thermodynamic work, moving a free piston faster. Watts overall output after generator, transmission line motor lights.

Or:

n(max) = (Th-Tc)/Th

No, Th-Tc does not equal Work out.

You are confusing thermodynamic work with output work and how work output changes with input. Yes work output changes when a load is put on and the throttle is opened and rpms change. But ∆V per stroke doesn't change. Adiabatic temperature change only responds to volume change if the mass in the cylinder is constant.

I can see where you are misguided on this natural phenomenon. The gas doesn't care what happens on the shaft. It only cares what happens to the movable walk/piston.

Your, losing the load so the engines over heat, is a different phenomenon. Try to understand the difference.

The implications are too far reaching to ignore and I can’t think of a reason why it wouldn’t work. I also asked the same question on the “Just have a think” YouTube channel and, so far, nobody has responded. It will take me a while to build it with my limited engineering skills and equipment!

Currently on a hiatus between Uni, not much to do. Anyways, I was working on repairing my ice machine when I came up with the same idea as I realised heat pumps have a higher COP than input by a considerable margin (if built correctly).
I've spent a while thinking about it, I'm going to attempt this myself too. I find it disheartening that most forums say this violates thermodynamics when in reality all you are doing is 'stealing' the heat from a source, ...

Hmmm? They must have been unable to find a heat pump and engine pair with the COP and efficiency needed, at compatible temperatures.

Offering nothing but name call and cursing. Good luck with that.

Can you provide compatible units?

I was hoping.

I'm still waiting for such a mythical contraption. Basically, you've just said, can't be done.

I'm still hoping. You are still failing to produce what you promise.

During the development stage, Maynard said the company had been separately approached by an oil company and a wind company, who offered large amounts of money to buy the technology “without plans to use it.” He suspects that they were trying to “bury the project” to protect their own industries.

“That is not going to happen, and we have made sure that nobody controls this technology but us,” he said. “This is technology that should not be suppressed."

I said you can't just take a conventional heat pump unit and a Stirling engine and put them together. They would have to be completely integrated. Put together from the ground up using basic components, refrigeration tubing, etc. That needs to be shaped to fit into the engine. No point in trying to hack apart an evaporator unit that's already brazed together, that would be crazy. Much easier to start from scratch.

So you are saying, can't be done with existing basic units of heat engine and reversible heat engine/pump.

I'm still waiting for the mythical bult from "ground up" contraption. Do you have an ETA?
