Re: Stirling essex - beta or gamma ?

I agree with calling the Essex a beta. I was pointing out the similarity of the gamma beta debate ah, to the square rectangle classification. All squares are rectangles, but not all rectangles are squares. All betas are gammas, but some gammas have the displacer cylinders further apart than others. ...

Re: Tesla's Ambient Heat Engine revisted

Skepticism born from fraudulent practices, isn't ignorance. Belief/disbelief isn't part of science. A scientific experiment doesn't care what the experimenter believes. Beliefs cloud judgement. Beliefs can obfuscate scientific papers. Humans are fallible. They fall into the trap of beliefs, and even...

Re: The TRUTH? η = 1 – (Qc / Qh) = 1 – (Tc / Th)

MikeB, I agree with your last two posts. Tom doesn't seem to want to prove himself wrong. His experiments typically output zero work, meaning that all the heat supplied, whether it makes it into the engine or not eventually ends up in the room's air at that lower temperature. This makes it 100% irre...

Re: Stirling essex - beta or gamma ?

All betas are gammas, but not all gammas are betas. Alphas are different, and similar.

Re: Tesla's Ambient Heat Engine revisted

Super charging. Same thing. Getting more air and fuel into the burn chamber. The engine must be sized and designed to handle the extra heat, otherwise the extra heat just gets blown out the stack. Higher internal gas pressure is one design parameter that helps here. Don't know what increased buffer ...

Re: Does a medium sized SE exist that could charge 12 V car battery properly?

Battery charging works best at amperages reflecting the capacity of the battery. Car batteries at around 10 amps. 2 is considered a finishing or equalizing charge rate. Less would be a "trickle charge", at best. Trickle charge isn't usually enough for a good charge. Furthermore, lead acid ...

Re: The TRUTH? η = 1 – (Qc / Qh) = 1 – (Tc / Th)

I find it odd that people accept a COP of 300 or 400 for a real heat pump, when the Carnot COP is 600 and 800. But have great revulsion to the same Carnot engine getting 16.67% or 12.5%, when a real engine gets 8.333% or 6.25%. It seems like a big incentive to cherry pick, or just plain deny simple ...

Re: Carnot was being too generous

It's funny how an "offer that can't be refused", leaves all those inventors, poor, discredited, often I'll, and followed by ever becoming more stubborn fools.

Only the well educated seems capable of seeing through their veil of lies, and self delusion.

Re: Entropy

Entropy IMHO is more easily thought of as uselessness of heat, and or dispersion. The same amount of heat at a lower temperature is more useless, higher entropy, lower pressure, larger volume. Able to do less work. Can't heat up your coffee, warm you in the winter, melt an ice cube. Temperature need...

https://en.m.wikipedia.org/wiki/Entropy Entropy is defined by calculus specifically a differential equation. The following is a line from Wikipedia: "So we can define a state function S called entropy, which satisfies 𝑑𝑆 = (𝛿𝑄rev)/𝑇 ." This when integrated on both sides becomes S=∆Q/T . Bu...

Nothing I've seen is more obviously faked than those garbage cooler unit videos. Nice try. There are scads of them too. The amazing thing is how many people those fraudulent videos seem to fool. Take a look at how uneven the coils develop frost and location of first frost. How little an amount "...

Entropy

Entropy. The thermodynamics definition boils down to: S = ∆Q/T Energy transfered, Joules, divided by Temperature, Kelvin. Both being real values therefore, Entropy S is a real concept and value, too. The following link does a fairly good job of introducing entropy. https://m.youtube.com/watch?v=DxL2...

Re: Tesla's Ambient Heat Engine revisted

Scientific studies have found 'belief' to be unreliable and has zero effect on experimental outcomes. Please don't take my word for that. Take meticulous data. Scientific/mathematical rigor is the only thing that will expose error. Even if a small amount of gas remains in the cold side of the engine...

Re: The TRUTH? η = 1 – (Qc / Qh) = 1 – (Tc / Th)

Excellent. I wish you the best on that. Is it part of the, Martin Tajmar's group at the Dresden University of Technology? I heard rumors they are working on similar EM devices.
