Re: Tesla's Ambient Heat Engine revisted

Here is another test. Fill a syringe with air. Place it in a vacuum. Measure the pressure by seeing how much weight it takes to depress it slightly. Cool it. See if it contracts. Measure again to see how much weight it takes to compress it the same small amount. Prediction: Nine tenths (9/10) (340 K...

Re: Compression cycle.. worthwhile?

For those that get it it does. For those that are experiencing cognitive dissonance it never will, their faith, denial and dogma are too high to let even blatantly obvious scientific facts in. And no one cares.

Re: Tesla's Ambient Heat Engine revisted

Then you also can't prove contraction, since the experiment proves pressure. Contraction and pressure are opposites. If one exists, the other can't. There is always pressure, even the vacuum of space has a ever so slightly positive pressure. Putting ice in the oven does prove freezing. Ice melts whe...

Work is put back in. Gets converted to heat. Picks up some of the rejected to cold sink heat. Puts both out onto the hot source.

Re: Tesla's Ambient Heat Engine revisted

To prove gases contract. A plugged syringe at atmospheric pressure, temperature and half full must be put into an ice water bath. After the air cools and the atmosphere pushed, compresses, in the cold gas. Put the bath and syringe into a vacuum chamber and evacuate the air. It will need to stay cont...

Heat is returned in a thing called a heat pump.

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

I know you've seen the following two video links before. When you make engines as capable as these, or better, using your theories, people will be more willing to listen. Until then you will get a lot of opposition. Be very kind to those that stop to listen, and even kinder to those that enter into ...

Re: Tesla's Ambient Heat Engine revisted

That is possible. They would have a fairly long distance to travel through the cold space. They Appear to be only a few degrees warmer.

Re: Tesla's Ambient Heat Engine revisted

VincentG, the power piston is on the cold, plate and side. There shouldn't be any hot gas there. Right? The main things increasing the gas temperature there would be compression from the reverse stroke, and heat from friction, and atmosphere, if warmer maybe.

Re: Tesla's Ambient Heat Engine revisted

Your power piston cylinder appears at a higher temperature than the top of the cold plate. I can only guess why from the information recorded. Work is certainly a factor to consider. What it read before running wasn't given to me. I would expect the top of the cold plate to not be changing temperatu...

Re: Compression cycle.. worthwhile?

"Ah..., that doesn't apply to Stirling engines", I've been told again and again. If not, why not. The energy represented on a PV diagram depends on path, and the direction traveled on the path. The initial difference between a Stirling Engine and a Stirling cooler is the direction taken o...

Re: Regenerators.... Have I got it straight what they do?

Matt ran into the problem, in one of his schemes, that the temperature of the regenerator was significantly higher than the regenerator so was ineffective in that adiabatic temperature range of the cold plate. Conversely it didn't get high enough either, for the hot plate. Changed his theoretical ef...

Re: Tesla's Ambient Heat Engine revisted

hopefully others will verify the results with their own independent research. I'm not looking for a "following". Following your experiments to verify them, is different from a following. But you knew that anyway, and thought the statement sounded cool, misleading, but cool. What I'm still...

Try not to tell people about me, you obviously know nothing about me. Your ignorance appears to be fostering your arrogance.
