Small pressure driven generator

[guilio2010]

A few years ago I remember seeing a small device that produces power from gas pressure. It wasn't any large, but it pulled gsa from I want to say 1/4" line and then after the drop, you would send it back into the gas stream of higher pressure. Anyone seen this before?

...of higher pressure

Was that a typo... supposed to be "lower pressure?


=====================================
(2B)+(2B)' ?

 

[guilio2010]

No, not a typo. It took a fraction of a gas stream, moved a turbine (pressure drop) and combined it back to another gas stream of higher pressure. If I remember the brouchure, it said something that it has minimal effect of the pressure downstream since it wasn't using enough gas compared the other stream to drop the pressure that much. If I remember, this was something on the order of 10W?!?!

Like I said, this was a few years back when I read this and I thought I still has the paper but just wanted to see if anyone else heard of it.

I wonder if the gas was reintroduced through a venturi arrangement.

Compressed air turbine is close. I don't see a picture of something that looks like it is manufactured but I'll keep looking.

Thank you!

We have used pneumatic-driven lighting for work inside vessels. The air supply was from an engine-driven compressor. The lighting units are commercially available.

That, if anything, would be the perfect overunity Dream.

Pull out high pressure gas, extract energy from it, re-inject at the same pressure? Sounds like perpetual motion to me.

Found it guys. It's from PGI. It's called a Zeus Pipeline Power.

I haven't seen much of it or any installed or even if this was a wild concept that was brought up but not working but anyhow there it is.

From the manual:
The TEC - 8 consumes a small amount of fuel
(3.0 CFH for N.G. and 1.0 CFH for Propane Gas )
in a flameless oxidizing catalyst to heat the hot side of
an array of Peltier thermoelectric modules.

Yes, definitely a typo, epete was right. Shall read "back to another gas stream of lower pressure" The diagram shows that it simply utilizes the pressure drop across the local pressure regulator to extract some energy that can be used to charge a battery.

I found a different Zeus charger when I Googled.

I came across the TEG also when I googled it. I actually was searching to something else when I seen the logo and remembered it for a couple years ago so it happened to be luck that I found it.

Pressure drop across the regulator. I love a clever idea.
