Runs on ice quite nicely also. A lot quieter.

When I lifted the engine out of the bowl some of the wet ice cubes adhered to the bottom. Pretty obviously not due to "refreezing". So there goes that theory.

Re: Tesla's Ambient Heat Engine revisted
Another point worth mentioning, a capillary tube type fixed orifice allows the system to equalize when the compressor is off. Having the system pressure equalized at startup in such a tiny low pressure system means zero high pressure at start up, so a low torque pump/compressor is all that is needed...

Re: Tesla's Ambient Heat Engine revisted
Here is a real DIY refrigerator. It has an explanation for temperature drop verses orifice. Ten feet of 1 mm tube for a larger pump. Those little butane ones need a much much smaller hole or longer capillary , and even then unlikely to get claimed temperature drop at all. https://m.youtube.com/watc...

...But it is such an obvious falsehood that I could have missed it by inclusion of the other misdirection pointless video, such as bending of the coils and such.

Re: Tesla's Ambient Heat Engine revisted
Tom, if they were more efficient than a Joule Thompson refrigerator, wouldn't they all use them? Solid state, freon less, noiseless. No they are less efficient. https://www.rigidhvac.com/blog/compressor-based-cooler-vs-thermoelectric-cooling-peltier https://en.m.wikipedia.org/wiki/Thermoelectric_co...

Re: Tesla's Ambient Heat Engine revisted
Unless, of course, you don't understand how it works. Then it might seem like it. Tom, you constantly, change the subject from some scientific point, "no orifice", to an attack on the person, "Pretty obviously he doesn't recognize common refrigeration components, even while watching ...

Re: Does a medium sized SE exist that could charge 12 V car battery properly?
The eBay ad for those engines says 15 Watts.
Something doesn't add up.

Re: Does a medium sized SE exist that could charge 12 V car battery properly?
Does this look legit to you guys? https://www.youtube.com/watch?v=ziZYVbLnSdM Looks way low to me. I can get nearly that much out of one of my small model engines with a cheap coin size generator. A big engine like that should be able to produce much more. Most likely they are using an automotive a...

Re: Tesla's Ambient Heat Engine revisted
Well, I'm undecided, personally. Just because something can be faked doesn't necessarily mean that it is in all cases. As James Randi said, of course, but, the explanation of how to fake it is probably more likely than the explanation that it works by magic. A simple, small refrigeration/heat pump ...

Re: The TRUTH? η = 1 – (Qc / Qh) = 1 – (Tc / Th)
Take a bicycle pump, extend it, and block the outlet orifice with your finger. Push the pump handle in and feel the warmth on your finger where it covers the outlet orifice as the air is compressed. That's kinetic energy being converted to heat. No let go of the pump handle. It is forced outwards b...

The pressure and temperature won't drop if the right amount of heat/energy is being put into the gas as it expands. ... What determines the "right amount"? Aside from the opinion of "Stroller". "Opinion" :laugh: We can calculate the Work W (in the form of heat energy) ...
