I am lying.
Even a habitual liar say truth once in a while. Perhaps you should listen to those times. Especially when math and logic are being presented.
Tom Booth wrote:The Carnot efficiency limit is baseless nonsense without foundation since it was based on the obsolete, depreciated, experimentally disproven Caloric theory.
So what! It is challenged by every first year ignoramus college student based on his religious beliefs that nature should be as he and his paster demands until they learn and teach themselves the logic of how it can be derived. Some never learn. It has stood up against every scientific and mathematic challenge of modern thermodynamic and physics theory. If you'd learned correctly, it is what ended the caloric theory. There is nothing in modern theory that contradicts it, but it does contradict Caloric Theory.
You're bashing something that you are ill-equipped to understand. It is humorous at best, but basically just mean and nasty.

Authority isn't being appealed to. All that is needed is a robust understanding of modern science. Inability to understand modern science is the inability to be an authority. You appear to lack that understanding.
If you only could supply the answer to; the integral of, 2X dx, and what it means, it will be a bare minimum begining of what you need to learn to understand Carnot.
P.S., I have no doubt that the "mechanical efficiency" of a Stirling could potentially be better than Carnot. To get the same work out per cycle a Carnot must be larger. But that is a mechanical problem not a thermodynamic efficiency.
All Senft's engines have regenerators. Read the book "An Introduction to Low Temperature Differential Stirling Engines" by James Senft.
He uses coffee filter material for the regenerator in his LTD Stirling engines. Especially the P-19.
He says, build one with and without a regenerator, see which one has more kick.
Please explain to me how you are going to pump heat from the cold sink to the hot sink at 10 Joules per run or cycle or Watts, and change the temperature of the cold sink when it is the hull of a battleship in the North Atlantic and the hot source is the sun because it's solar powered?
Heat pumps in the winter are for keeping your house at a constant temperature inside, while pulling heat from the infinite capacity outdoors cold atmosphere. To make up for heat transfer through the insulation.
In the summer they keep your house at a constant temperature by pumping heat out of the house and pushing into the outdoors infinite hot atmosphere. To make up for heat transfer through the insulation.
Transferring heat can at times have little effect on source or sink temperature if their masses are very large compared to the engine.
For a smaller mass, such as a refrigerator, running the heat pump only cools the inside by a few degrees and heats the room by only a few degrees. Yes, on startup it changes by more, big deal, just a transitional period.
If you insist on digging. It is like digging a small hole in the floor of a valley near sea level, and depositing it on top of mount Washington. It is a very small change in relevant elevation difference. 6288 feet pretty much with or without the addition of a 6 inch hole or mound. Especially if you walk up the hill for each dirt scoop. Heat pumps must move little amounts of heat up the full temperature difference hill.
At startup, for a refrigerator the Carnot COP is infinite. For a Stirling engine, that startup COP would be met with an efficiency of zero. Zero times infinity in this case will have a value of 1 or less, 100% or less.
