Re: The Carnot efficiency problem

Re: Tesla's "Ambient Heat Engine" Experiment

Another thing I think happens is on the return stroke the air in the cylinder is compressed, maybe not to the extent that air is compressed in a fire piston, but the principle is the same. https://youtu.be/-39wmSBO2FM It seems strange that you have ignored that fact and are now attempting to conjur...

Re: Tesla's Ambient Heat Engine revisted

... I just have one more question, how does ipoo get -32 degrees C out of a chemical that boils at 10 degrees F, in a system that is running at atmospheric pressure? ... Funny how you believe the video can be easily faked by letting butane evaporate on the outside of the pipe, but can't believe the...

Re: Tesla's "Ambient Heat Engine" Experiment

An Air-cycle refrigeration system works by: 1) compressing air 2) releasing the compressed air through a turbine or reciprocating piston engine to extract work from the air. A Stirling engine appears to do the same thing, or carry out the same process. Air is compressed in the cylinder. The air then...

Re: Tesla's "Ambient Heat Engine" Experiment

... .. If Tesla was right , the ice in the pan on the left with the running engine on top should melt more SLOWLY than the pan on the right with a non-operational engine since the running engine is converting some portion of the heat trying to reach the ice into another form of energy. ... The only...

Re: Tesla's Ambient Heat Engine revisted

My my, there are even 0.85 volt peltier modules. How low can you go? They can also be "stacked" for greater ∆T and better heat separation. Also running them briefly gives better efficiency as each module can only create a certain ∆T, once reached they quit working, still consume power, but...

Re: Tesla's Ambient Heat Engine revisted

According to Tesla's theory... If we first ran the Peltier module to cool the bottom plate. (Keeping it insulated of course, to preserve the cold). The engine could then run on the surrounding ambient heat, and with perfect insulation and a 100% efficient engine, it could run indefinitely. He recog...

Re: Tesla's Ambient Heat Engine revisted

... BTW Tom, here's a tidbit I'll blow your way...I was born in Rochester, NY and lived on the Erie canal as a kid. So, let's just say that I'm more than familiar with the cocky know-it-all mindset that plagues the region. Well that explains a lot. I guess you should if you grew up there. I didn't.

Re: Tesla's Ambient Heat Engine revisted

Let me ask you fool. Do you doubt that evaporative cooling (using water) can reduce the temperature of the air? i.e. "swamp cooler". Why, OMG, how is that possible! Water boils at 212°F !!!!! You couldn't possibly use evaporating water to cool below 100°C !!!! Evaporative cooling with wat...

I don't think anyone needs "faith" to build an air-cycle refrigerator.

Re: Tesla's Ambient Heat Engine revisted

Oh, BTW, while we are on the subject of the "orifice" in a refrigeration system... There are of course several types. A refrigeration or heat pump system consists of two basic components. 1) a compressor or pump of some sort. 2) a tube or pipe connecting the pump outlet with the pump inlet...
