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:

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 ...

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 ...

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.

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...

-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.

The power supply to run that little freezer was allegedly, just 2A Compress_20240514_164949_9056.jpg 24 watts for an alleged nearly instant -30°C in open air. I guess I'm probably wrong, but that doesn't seem like that high of a bar for a small Stirling engine. 4 watts from this setup: https://youtu...
