Re: Perpetual Ideas

I think that chart is for steady state currents and temperatures and COP's. At 0.1 times Amax, it will produce 10° of delta T, at a COP of 2. At 0.2 times Amax, it will produce 20° of delta T, at a COP of .7 Very tiny amounts of power for small steady state COP's, and delta T's, max. Not sure how r...

Re: Tesla's "Ambient Heat Engine" Experiment

What Jeremiah says near the begining of this video about the importance of the pump to create a vacuum in the turbine to greatly increase the efficiency of the turbine also sounds very similar to what you are proposing, using the pump as a kind of replacement for a cold condenser. https://youtu.be/h...

Re: Tesla's "Ambient Heat Engine" Experiment

Personally, Paul here seems to know what he's talking about. https://youtu.be/f4UmvPLmV40 In this interview he mentions ienergysuoply (Jeremiah) as a partner he was working with, which makes me tend to think Paul may have been Jerimiah's partner that died, but whatever the case he seems to not be co...

Re: Tesla's "Ambient Heat Engine" Experiment

The intro blurb in the previous video says "compressed humid air" is supply to the turbine. This is, I think, similar to this phenomenon: https://youtu.be/2hYQtB4QkEY But as Jeremiah commented, this normally requires high pressure. A shop compressor that big as in this video is probably at...

Re: Tesla's "Ambient Heat Engine" Experiment

It seems this was low pressure "cold steam" driving the turbine ? The second stage turbine providing the vacuum rather than a condenser/ice bath Still, producing a 100°f drop in temperature at the turbine. It is a bit frustrating that the circumstances and actual details of this test are n...

Re: Tesla's "Ambient Heat Engine" Experiment

I believe this is the double two stage turbine without any condenser or load, still, there is already ice forming within the turbine. https://youtu.be/c5NzHvGxTss This was five years ago, which seems like the more recent developments are somehow less advanced ? One of Jerimiah's comments says: . It ...

Re: Tesla's "Ambient Heat Engine" Experiment

A fairly simple experiment I'd like to try when I get a turbine, which may be in a week or so, tracking says it is on the way, from China, would be this: Compress_20240602_080527_7386.jpg This would, of course, have to be a "saturated vapor with all air removed from the system. This could be ac...

Re: Perpetual Ideas

My understanding at the moment, (which could be wrong, as I've only just begun looking into these things and some of the informations is contradictory or confusing) Is, what that chart indicates is when first starting up a Peltier device is at 0°∆T and it's power draw is low and it's COP is basicall...

Re: Heat is never hot or cold. Internal energy can be hot or cold.

What I object to mostly is how (added) "heat" and (existing) "internal energy" are treated as equivalent for the purposes of the "Carnot limit" equation η=(Th -Tc)/Th ⋅100% Tc is the internal energy before adding heat Th is the internal energy after adding heat Th - Tc ...

Re: Perpetual Ideas

I was just browsing the internet for small HVAC compressor pumps. There are a couple companies making mini refrigerator compressors. One is Rigid: Compress_20240601_015658_8992.jpg 12 volt DC Compressor, smaller than a can of soda pop. Not really a lot different from some of the little butane refrig...

Re: Tesla's "Ambient Heat Engine" Experiment

There is a vacuum between the nozzle and the pump. ... Well, I don't want to discourage your efforts, I could always be wrong, it just seems like your putting the cart before the horse. There would be a vacuum, if there was a vacuum to pull air through the nozzle to turn the turbine to turn the pum...

Re: Tesla's "Ambient Heat Engine" Experiment

I don't really see any chance.whatsoever of that working, to be honest. Any elaboration on that? Because I'm convinced it'll work with a delta T. And might with ambient air. I probably just lack the explanation skills. I guess we'll find out. I'm happy to fail, but I will try anyway. Maybe I'm not ...

Re: Perpetual Ideas

I think your first pic, of the contact strips, is possibly the best, but I would put them on opposite sides of the displacer, and use a metal wheel as the other side of the connection. I'm worried about the weight that all of this would add to the displacer though. The most interesting thing about ...

Or maybe generate a current within the displacer?
