Tom I'd recommend you spin one of your engines by hand and take note of when the displacer fully exposes the hot plate. I have, probably 1000 times. Of course, you may have a different idea about what constitutes "full exposure". An LTD displacer moving up, off a hot plate has "full ...

Then the cold working fluid gets hot, expands and does work, converting the heat into mechanical motion. The result being that the working fluid cools back down due to work output or the conversion of heat into work. Cools back down to the original cold temperature before heat was added, OR COLDER....

Hopefully this video definitively shows that the displacer timing is 180 degrees behind the standard. The crank assembly is pressed together and hasn't been modified. It is the same as all Essex engines that can be viewed on YouTube. https://youtu.be/F3dqnWTgpWc?si=oWAuizocmAkX40yV I don't know, bu...

... you need to be wary of the readings from IR thermometers, ... When you prefer to cling to 200 year old obsolete theory over modern instrument readings there can be no more progress. When you are blind to obviously significant current video evidence preferring petrified centuries old speculation...

I've found through experiment that work output alone is sufficient even when heat "rejection" to any "sink" has been eliminated. In fact, eliminating the "sink" almost invariably increases RPM and power output rather than reducing it, as might be expected due to heat b...

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.

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...

We are not trying to debunk you. ... A blatant lie. Nearly every post you've made in this forum since you arrived as "fool" has been almost invariably directed at proving me wrong. Including this one: You have "real science" and you are only trying to "help". Your moni...

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 ...

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...

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 ...

Maybe Matt could tell us again why "Uncle sugar" or the SEC or US military goes after free energy garage inventors to destroy them. He seems to know all about it. If you guys are so sure of your "Carnot" fairytale nonsense, why waste all your time on some obscure model engine for...

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 ...
