...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. Common magic trick misdirection techniques. ... OMG! The coils are bent, for the same reason the coils are bent in a still. To save space...

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...

Unless like MikeB you didn't even watch the video(s).

Sorry, that was VincentG who mentioned he hadn't watched the videos.

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 ...

The eBay ad for those engines says 15 Watts.

Something doesn't add up.

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...

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 ...

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) ...

Who said it was. I've obviously moved on to a different topic.

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...

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...

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...

This is going to take a while:
