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...

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

Re: Tesla's Ambient Heat Engine revisted
BTW if anyone is tempted (like me) to buy one of those tiny 30 watt football helmet size beer coolers for the compressor : Compress_20240516_144948_8345.jpg Don't bother. I was talking to the stock boy at Big Lots where they had some of these on sale, I said: They couldn't say " Low noise compr...

Re: Tesla's Ambient Heat Engine revisted
Is anyone familiar with these inline high pressure fuel pumps? Compress_20240516_124949_9044.jpg Designed for cars with fuel injection. Up to 125 psi MAX. Flow rate 135ltr/hr @ 3bar (35 gal/hr @ 45 psi) Maximum pressure 8.5bar (125 psi) Seems like more than enough pressure. From what I read somewher...

Re: Kontax KS90v thermal experiments
One down: https://youtu.be/b8ExVO1WIwc Sounds a bit scratchy to me. Not sure why. This doesn't really seem to be a "heat of your hand" engine. At least I couldn't keep it going on just heat of my hand. It's a fairly warm day though, and it hasn't been broken it at all yet. Runs beautifully...

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 those that can't be bought. Only the well educated seems capable of seeing through their veil of lies, and self delusion. By ...

Re: Tesla's Ambient Heat Engine revisted
Tom can you unpack that? How would it work without an orifice? I didn't say it would work "without an orifice". Fool claimed: They don't even have an acceptable orifice. Didn't make or install one. Pretty obviously he doesn't recognize common refrigeration components, even while watching ...

Re: Tesla's Ambient Heat Engine revisted
Case in point.
Apparently you don't know much about refrigeration.
Anyway, I'm adding this to my projects list. The more of these little butane refrigerators
I see, the more convinced I am it can work.

Re: Tesla's Ambient Heat Engine revisted
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 &quo...

Re: Tesla's Ambient Heat Engine revisted
-32°C with a 9 volt battery?

I think I'd have to see it to believe it.
The guy does seem to understand air conditioning systems though.
