Re: The TRUTH? η = 1 – (Qc / Qh) = 1 – (Tc / Th)
Well, fool, after going through your derivation I find no particular MATHEMATICAL flaws. If you have a temperature difference at the hot plate of 400°K for example, and a cold plate at 300°K you have a ratio on the absolute temperature scale. In this case 25% 300°K is 75% of 400°K. It's undeniable t...

... Qc then becomes DQc the heat rejected per cycle. Minimize this to zero if possible. Determined by Derivation and Calculation once 'n' is known. ... To be clear, your 'n' I suppose represents η, Greek letter eta, The symbol for Carnot efficiency ? Do we not already know the Carnot efficiency ? T...

Re: The TRUTH? η = 1 – (Qc / Qh) = 1 – (Tc / Th)
All that you just posted is hog wash. No, the way you phrase your statements is at best ambiguous and needs clarification. Please try to make sense. Definitions of mathematical variables require precise definitions not slippery, meaningless nonsensical definitions that could mean anything and later...

Re: The TRUTH? η = 1 – (Qc / Qh) = 1 – (Tc / Th)
This again? fool? First off, it looks like the same old merry-go-round Let Qhz be the internal energy from heat added to the cycle all the way from zero K Kelvin to Th. Can you unpack that sentence please? How is "internal energy" from "heat added"? You said the heat added (DQc, ...

Re: The TRUTH? η = 1 – (Qc / Qh) = 1 – (Tc / Th)
Yes, "energy" in a sense, goes "through" the engine 100% It goes in as "heat". "Heat" is, of course, a term applied to a human perception. The "heat" going in is a form of energy. The heat is taken in by the gas causing it to expand and put pressure ...

Re: The TRUTH? η = 1 – (Qc / Qh) = 1 – (Tc / Th)
Maybe it would be helpful to draw a distinction between passing "heat" though an engine and passing "energy" through an engine. And yes I know there's no such thing as heat. What I mean is a distinction between passing total temperature through v. passing total energy through? W...

Anything? I'd love to see it. So far, in ten years I've seen nothing. Please! Please! Please... Show me the "reverification". You've seen plenty. ... As usual, empty handed. Nothing but blah blah blah... If you had any concrete evidence of the validation or "revalidation" of the...

Re: The TRUTH? η = 1 – (Qc / Qh) = 1 – (Tc / Th)
... If a waterwheel can put out work with all the mass going through, losing some of its energy by altitude drop, a heat engine can output work if all the caloric goes straight through losing some of its energy by temperature drop. By Kinematic Theory: all the energy, heat or otherwise can't go str...

Re: The TRUTH? η = 1 – (Qc / Qh) = 1 – (Tc / Th)
Don't know what's "cold" about 100°C Anyway, your making up numbers or "rocks" out of thin air imagination proves not anything at all. The fact is the "Carnot engine" and/or cycle, as published in Carnot's book in 1824 "transported" ALL the "Caloric"...

Re: The TRUTH? η = 1 – (Qc / Qh) = 1 – (Tc / Th)
Perhaps you make a valid argument. The same could be said, however, of Kahn's Carnot engine. https://youtu.be/aAfBSJObd6Y If not, why not? He removes rocks to expand the gas then replaced all the rocks to compress the gas. If my "ideal" engine is bogus then the Carnot engine also does zer...

Re: The TRUTH? η = 1 – (Qc / Qh) = 1 – (Tc / Th)
Tom, by "removing rocks" you are reducing the inside pressure. .... ...That is why it will generate zero CYCLIC work. ... Even your description conveys zero work. Rocks are removed, forward stroke. All the same rocks are put back on, return stroke. Equal and opposite "rock" work...
