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...

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 ...

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...

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...

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 ...

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...

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...

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 ...

Aaron apparently, in his own words in this podcast thinks suppression of technology, at least in some circumstances, is "just good business practice". https://www.podchaser.com/podcasts/the-higherside-chats-27046/episodes/aaron-murakami-jeremiah-ferwer-150784081 Hard to determine who are t...

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?

Or maybe the wires could be routed up through a hollow connecting rod:

Maybe transfer the electrical current through via some contact strips ?

Somehow the above scenario seems highly unlikely to me. For one thing, the efficiency of Peltier devices generally is notoriously rather poor. For the above to be true, it would suggest that ALL the heat generated by the input current would somehow only appear on the hot side of the chip. At any rat...

Ah yeah since his previous partner died. But Jeremiah was going in the heated fluid direction before already. ... Perhaps it was the departed partner who was into the ambient heat aspect. In that case I wouldn't expect anything more of interest to emerge from the new partnership. Compress_20240530_...
