The above forum poster referred to his website as a source of more information.

The site, though, is apparently defunct.

Plenty of saves from that time period though. So browsing the site on the Wayback Archive I found this related page, a mirror of a Scribd article:

https://web.archive.org/web/20220716080 ... UxqpCrSdmP

Needless to say, it is quite long and I've hardly begun to read it.

Interesting though, how this is circling back to Stirling Engines.

It is notable that the reference to this Proell Effect started out on a video about the buoyancy engine, which, my theory was, must rely on the absorption of ambient heat.

Another apparent confirmation, as the stated effect appears to be all about a "Super Stirling Engine" that can utilize ambient heat by getting colder than ambient, but the paper suggests that the engine must be appropriately insulated in order to achieve this.

Right up my alley.

Interesting claim in this PDF that introducing air into the bottom of the tank can create a "vortex" that causes air to continue to be sucked in from the air pump.

A cone situated above the air nozzle is supposed to assist.

You sure seem to rally with the crowd that figures, if the words are undecipherable, it must be true. I'm just the opposite, if I can't understand it, I'm not buying it.

The more I read, the less likely that they have any validity. Sorry. Not buying it. Still waiting for a working model.

I agree the claims are very dubious, unlikely, unbelievable, but not disproven by speculations in a reddit post.

Here is another hit job that IMO does not seem to have any real substance.

The accusations detailed seem to be hallucinations. Simple changes in lighting or camera angle or pure imagination

Very convincing and probably ruined the company regardless if the technology was legit or not.

This video is fairly recent. Mention is made of how the systems pictured operated through COVID.

Looking closer at the supposed upsidedown bracket and supposed color changing cable:
The second photo is brighter, so the cable in the middle looks brighter. It hasn't "changed color".

What about the bolt spacing?

Well the lighting and/or exposure is different. The camera angle and shadows are different.

But take a ruler or paper and actually mark or measure the spacing.

It's identical.

Near as I can tell the Proell Effect is another mythical Maxwell's Demon and in no way a realizable idea. In other words, a scam, quackery, a hoodwinking. The only information comes from one paper and Goldes.

Wikipedia hasn't even touched it.

Here, allegedly, there is supposed to be clear traces of a hole that was covered up, filled, painted over...
I played with the contrast, brightness etc. trying to see traces of a hole in this picture
Does anyone see a hole?

I've tried, but I don't see any hole. Trace of a hole or patch or fresh paint.

Yes, it appears it is just the one paper. IMO very interesting anyway, though I haven't had time to read it.

Your opinion that, " is another mythical Maxwell's Demon and in no way a realizable idea. In other words, a scam, quackery, a hoodwinking" is just that. One person's opinion.

Strange how closely, at least from what I've read so far, this researchers findings coincide with my own.

Insulating a Stirling engine apparently improves the efficiency. How odd that someone else observed the same thing, as far as I know, I dependently.

Does that sound like anyone we know! It seems common for scammers to name call and curse the science crowd. Perhaps one day people will learn better.

Has nothing to do with opinion. Has to do with production of a working model. I'm still waiting.

Now that I've had some time to read through the Kenneth M. Rauen paper on the so-called "Proell Effect", this is nothing new.

It is given full treatment in Rudolph Vuilleumier's 1918 patent where he refers to it as simply "secondary heating". In the paper it is called "self-heating".

Vuilleumier describes a type of heat driven heat pump that does not require any work input to move the heat. Same principle given a new name.

Same thing I've been talking about in here, that one aspect of a Stirling engine is that it acts very much like a. Vuilleumier heat pump or Maxwells demon.

"Self-refrigeration".

Sound familiar?

https://youtu.be/P11q-BAhvqk

I'd call this independent corroboration.

.

Thanks. You just pointed out the flaw in VincentG's combined heat pump engine scheme. A Vuilleumier Heat Pump, (is not Maxwell's Demon), requires a source of high temperature and medium temperature. The section being refrigerated must be isolated/closed from the hot and medium temperatures. The goal is a cooler area than ambient medium temperature.

The heat going in, minus some of the heat going out, is converted to work, and used to pump more heat from the cold space to the medium temperature space. The medium reservoir must be extensive enough to not change temperature much, such as ambient outdoors. It could be solar and ambient powered.

VincentG's idea was to take heat introduced to the cold space, to run an engine. The goal was to cool the cold space by pumping heat from the cold space to ambient outside hottest space.

It does that by having an even colder space. All the heat gets pumped uphill. The best the overall efficiency will be is the same as a well designed heat pump, pumping heat between the inside and outside temperatures. It likely will require a larger and more complex contraption. Having an artificial colder intermediate self cooled plate, won't change the overall process, nor efficiency. It just adds complexity.

You obviously don't know what you're talking about, and miss (or just ignore) the point about the Proell effect, entirely.

Perhaps most interesting, they rolled the portable unit out into the parking lot and let it run for an hour.
No hidden batteries.

How could anyone tell. They would be hidden.
