Re: Tesla's "Ambient Heat Engine" Experiment
Heat is not internal energy. To imply that the two are the same, as you often do, is misleading. To claim gases contract, as you do, is misleading. A Stirling engine has to concentrate heat by other means, certainly not by heat being "rejected to the cold plate". Especially considering at ...

Re: Tesla's Ambient Heat Engine revisted
Orifice=expansion valve=properly designed capillary tube=manually adjusted valve=needle valve All of which are missing. If you expect someone to believe that a short tiny length of not much smaller diameter tubing in a system with a tiny pump is equivalent to an orifice, please show us the numbers. ...

Re: Tesla's "Ambient Heat Engine" Experiment
The "lost" kinetic energy is converted into heat. What is less misleading? 1: The "lost" kinetic energy is converted into heat. 2: The "lost" kinetic energy is converted into internal energy as seen by a temperature and pressure rise in the gas. Or are you implying tha...

Re: Tesla's "Ambient Heat Engine" Experiment
A turbo charged diesel engine uses an intercooler between the compressor and intake to the cylinder. Pretty sure Tom was talking heat of compression, the very basis of diesel ignition. Turbocharging and intercooling diesels has improved them to the point where they can be an effective automobile en...

Re: Tesla's Ambient Heat Engine revisted
The name calling is against forum rules. Please stop. Main Board Rules: General Rules A) Please treat everyone with respect. If you have a point, then make it. Driving it on and on will not be tolerated. You post to nearly all the threads, and you drive in over and over the same anti Carnot and educ...

Re: The Carnot efficiency problem
I'm going to tell you a little secret. Your opinions here aren't better than anyone else's. Eliminating people out of disrespect or administrator interaction is not helping this site. Just remember that other people being wrong is no reason to disrespect them. Your actions here are very disrespectfu...

Re: Tesla's "Ambient Heat Engine" Experiment
Towards the end of the Stirling's compression stroke the displacer is moving the gas to the hot side, and the regenerator is heating the gas. Your description is misleading.

Re: Tesla's Ambient Heat Engine revisted
The capillary tube is the "orifice". It's diameter and length must be sized to the pressure difference, and flow rate. Longer and narrower for lower flows and higher pressure drops. Shorter and wider for higher flows an lower pressure drops. Higher pressure drops are needed for higher temp...

Re: The Carnot efficiency problem
Tom, how about some simple old world math where eff = output/input as in simply measure work out vs heat in ? No waterfall, tug o' war, or calculus req'd... I think we've already discussed a number of perceived problems in doing that. How to get a verifiably accurate measurement of heat "in&qu...

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...

True. It won't even help if you get just faith. Money maybe. But building a perpetual motion machine, probably nothing will help. But I want one, so please build one. "He further reasoned, that when heat did need to be removed from the "cold hole", it could be taken out "by its o...

Re: Tesla's Ambient Heat Engine revisted
And maximum efficiency can be identified by the temperature difference between hot and ambient. And cold and ambient. Depending on work and heat travel directions. Real engines will be worse. Glad to be back on the subject of this thread, "Tesla's ambient heat, generated cold hole, perpetual mo...
