Re: Isothermal Heat Transfer
I'm wondering how this arrangement would work if the displacer piston were tight fitting and the displacer chamber was open to atmosphere at the end. Kind of an opposed cylinder Alpha.

Re: Isothermal Heat Transfer
The phasing IMO, or observation, from what I can tell from videos on YouTube of Essex engines actually running, the phasing or timing appears to be identical to all other Stirling engines. Defining TDC as "full compression", (minimum volume for the Power piston) with the displacer 90° ahea...

Re: Tesla's Ambient Heat Engine revisted
Sorry, this is incorrect: In fact, there is really no such thing as "isothermal" in the real world, that transfers heat without a temperature difference, even if given "forever". Boiling water and similar phase change processes can be ACTUALLY isothermal. Both the temperature of ...

Re: Tesla's Ambient Heat Engine revisted
The condenser is the ambient temperature heat rejection exchanger. Yes it is isothermal. It gets hotter than ambient so heat will come out. A delta T is needed for heat transfer. If it were quasi static it would be more efficient. It isn't, so it can, and does, have a higher wattage. It cools faste...

Re: The TRUTH? η = 1 – (Qc / Qh) = 1 – (Tc / Th)
You really do sound like an Al that has run amuck. When you quote me and bold and underline everything except the word 'negligible', you under emphasize that word. That is a form of twisting others words. No it isn't. It's giving emphasis to point out how the entire jist of the bolded text clearly ...

Re: Tesla's Ambient Heat Engine revisted
The Vuilleumier cycle requires hot and ambient to run the machine. It requires a insolated space to cool. As you point out, three temperatures. And the heat absorbed from that cold space is rejected to ambient. It won't work trying to cool the ambient temperature and reject to the hot space. It nee...

negligible too slight or small in amount to be of importance. https://dictionary.cambridge.org/us/dictionary/english/negligible Twisting my words again. Negligible was not "thrown in". It's well defined. Well glad you looked it up, because it really didn't fit in with your claim that the ...

Re: The TRUTH? η = 1 – (Qc / Qh) = 1 – (Tc / Th)
I came across two opposing theories. One says basically heat is a fluid and runs through a heat engine like water. The other says heat is energy and basically "disappears" inside the engine, as it is converted to work. If the latter is true, then it is really not necessary to design an en...

Re: Tesla's Ambient Heat Engine revisted
... Actually your refrigerator works on a different process than Carnot or Vuilleumier cryocooler. The Vuilleumier cryocooler requires hot cold and ambient. The heat absorbed by the engine at high temperatures and at low temperatures is rejected at ambient temperatures. https://link.springer.com/ch...

Re: Tesla's Ambient Heat Engine revisted
Have you measured this heat you think gets transfered to the "cold hole" in a running Stirling engine? No. Have you? Of course. only like 20 times. Or at least I've tried. But you can't measure what isn't there. Of course fool and company just say I'm not getting an increase in temperatur...
