Molecular attractive force isn't changed by temperature. Temperature is only equivalent to velocity. Nobody said temperature "changes" attractive force. Quite the opposite, I said the molecular forces are always there, just as magnetic force is always there. Cooling reduces the "repe...

Anyway, here is someone else's opinion: too little advance or retarding the ignition will push the piston down as the crank is pulling it down which will reduce the force of the gas expansion. https://www.pistonheads.com/gassing/topic.asp?h=0&f=23&t=1347125 If you think the principle doesn't...

I don't see it. The gas in a Stirling is always in contact with the hot plate or cold plate. This indicates heat transfer any time the gas is a different temperature. Timing has nothing to do with heat transfer. The gas on the hot side picks up heat until moved to the cold side where it loses heat ...

I can "prove" my claim.

8+8=16

16/2=8

Let Tls = Tom's left shoulder
Let Trs = Tom's right shoulder

Tls + Trs should add up to 16

Just look at the numbers!

... One leads to another. Another leads back to one. That's the way theories are. Then comes all attempts to disprove it. Round and round we go. Circular reasoning. Modern science considers theories that depend on failure of "attempts to disprove it" pseudoscience. Popper's principle of f...

.... Tom, magnets don't work that way. .... What way? I don't think I said anything about how magnets work. If you hang two magnets from strings or just push them across a table you have to apply some pressure, is all I said. Then eventually, as the magnets get closer the pressure between your fing...

Here is a Google AI summary that I think is somewhat applicable: A gas expanding into a vacuum, also known as free expansion , does no work because there is no external force opposing the expansion. Work is defined as the force applied on an object times the displacement of the object in the directi...

.... ... So Qhz should have the same relation ship to Qcz that DQh has to DQc, in other words , 'n' is the same. Basically this says that Qcz can be calculated from 'n' and Qhz, or: Qcz = Qhz•(1-n) Substituting that equivalence for Qcz into the 'DQh' equation: DQh = Qhz - Qcz (DQh equation) Qcz = Q...

... Somewhere someone made the claim that Stirling Engine expansion is "more adiabatic". I think that is misleading. https://en.m.wikipedia.org/w/index.php?title=Stirling_cycle&wprov=rarw1 "This article is about the adiabatic Stirling cycle. " Very misleading. Without heat g...

... 0k is only an advantage when a heat engine needs a heat sink which is what Tom is trying to circumvent. .... Not to be overly picayune, but I guess I'm overly sensitive about mischaracterizations. Anyway, again, I'm not "trying to circumvent" anything. Just trying to determine the fac...

I mean, this engine is ALL acrylic. Sides top, power cylinder, everything but the bottom hot heat input plate. It is sitting on a 100 Watt ceramic heating element. With all that heat, potentially going in at the bottom and nowhere else to go, the engine is running like a bat out of hell and just kep...

So next cycle. Again add heat at 400°K but if heat is not "rejected" our ∆T quickly diminishes. We have a bottleneck. After a few rotations the ∆T should get completely washed out. Well, what if ∆T doesn't matter? Suppose by "upgrading" the quality of Qcz DQh is less diluted? Sup...

Well, so far at least, the way I look at it is Qcz is like a reserve tank of gas that I don't have a key to unlock so can never use (so far as is generally recognized anyway) DQh however is high grade fuel put in at 400°K So there is this 4:3 ratio 300°K to 400°K I've supplied fresh fuel of the high...

I think I figured it out finally: Compress_20240421_122627_7772.jpg Drawing out a picture of the two "ratios" described, and adhering to the Carnot theory. The little rectangle in the upper left of the bottom right rectangle is the "work" or maximum heat input that can be convert...

... That allows us to look at the total energy in the system. So Qhz should have the same relation ship to Qcz that DQh has to DQc, ... I've been trying to work out what you might mean by this statement. "Qhz should have the same relation ship to Qcz that DQh has to DQc" First of all, why...
