This looks quite a lot like some ideas that were floated in heat not too long ago using towers to generate pressure differentials, VincentG I think?

If I'm interpreting this right, it looks basically like an air-lift pump in one column of fluid causes the liquid in the left columb to be lighter, due to being full of air bubbles.

The weight of the all-fluid columb is greater than the fluid-gas bubble (air-lift pump) side causing a circulation at the bottom between the two columns or "towers" that can drive a turbine.

The gas from the air lift side is simply recirculated back down to the bottom of the tower.

Apparently the air-lift side fluid is also solar or waste heat heated which causes the bubbles to expand as they travel upward allowing a net energy output.

Heating and cooling necessary.

Heating, yes.

Cooling?

Where do you see cooling?

It says thermal energy is CONVERTED to kinetic energy.

There is no cold "sink" or "reservoir" anywhere in the system. No dumping of "waste heat".

"Almost 5X the output of PV on ¼ the land"

So if PV is about 20% efficiency....

X5 = 100%

X4 = 400% efficiency? (or COP)

These guys are commercial cascading heat pump manufacturers.

Of course, some consider it a "perpetual motion scam":

https://www.reddit.com/r/AskPhysics/com ... perpetual/

nowhere do I see any sort of temperature gradient to drive a turbine

Do you still "like it", Fool?

At the top of the tower in the left hand side, it says, "Hot gas under low pressure is captured and recirculated."

Then at the bottom it says, "Cool, high-pressure gas is injected here." I'm fairly sure you don't understand that, that means it is cooled to make it cool.

I don't even know if you realize that going from low pressure to high pressure heats a gas. Or if you know that, to get cool gas from hot gas it needs to be cooled. Or if you know, if you try to compress hot gas before cooling it, it will cost more back work and be even hotter. Or if you know, that exhausting hot gas into the atmosphere is a form of heat rejection. Or if you know, that when compressing cold atmospheric air, it gets hotter, so then, it needs to be cooled by rejecting heat before it is cool again.

Yes, I would say that the 'in the know' designers of that system, are using classical scientific thermodynamics and mathematics. Hmmmm, could Tommy be wrong all these years of bashing. He still can't read an adiabatic line on a PV diagram or what it takes to move between those lines.

It would be so much easier for him if he'd just gotten an education rather than making fraudulent guesses leading to his denial of those scientific data based charts.

Liars and ignoramuses are always exposed. Your nakedness is obvious on these points.

It is genius because only the gas is being heated and cooled. And, the two temperatures can be separated by long distances. Cooling could be underground or in a home.

It looses out on a regenerator. But who cares, solar power is free. Carnot to the wind, efficiency will be low.

Maybe a counter flow heat exchanger can scavenge some heat from the hot low-pressure gas, then be used to reheat the cold high pressure gas just before it is injected at the bottom. Not shown in the schematic. They are either, keeping it a secret, or need me as a design consultant.

It doesn't say anything about, or show any external or outside cooling system.

Possibly the heat of compression from the compressed gas is taken in by the circulating fluid. Not enough detail.

Someone on a forum states:

It claims to use ambient heat

https://coalpail.com/coal-forum/viewtop ... 5&start=15

I haven't seen that claim, but they do say it operates 24 hours ("with proprietary heat storage").

If the hot gas required additional external refrigeration that would certainly drastically reduce the output of the system, probably making it impractical or impossible.

So far, no external "cold reservoir" outside your imagination.

That would certainly doom them to failure.

Supposedly they already have a demonstration model, if not an installed system already operational.
https://flooidpower.com/power-generation/

During the energy production process, the system uses efficiently compressed air to displace its signature Flooid, while at the same time capturing, concentrating and converting ambient heat into electricity.

It's being rejected during the compression, and by the exhaust to the atmosphere. Heat in from solar. Heat out by exhaust to ambient and rejection during compression/back work.

Squirming like you are by posting a large volume of irrelevant media is showing your ignorance.

Compressed or compressor means back work and heat removal. If they are saving that heat, they aren't showing it.

Claiming it uses ambient heat, and the tower is at 650F is incompatible.

More contradiction.

That's not what the article stated:

“We spend 50% less energy to compress air than a normal compressor, and we capture 100% of the heat in the process.”

Not " Heat out by exhaust to ambient and rejection during compression/back work."

The only contradiction is in your lack of reading comprehension, as usual.

Again, in this video:

https://youtu.be/OWX__r2lu6w

"We are able to use all of the heat from the compression process".

And in the video description:

Flooid Power Systems compresses large amounts of air 50% more efficiently than current technology, while re-using the heat of compression...

Conceptually, no different from what I've been saying for years. Just a different king of engine:

Wrong video link though my video was included on that previous page somewhere

So by compressing the air, you not only get the heat out of the air (solar energy) but you also get back the work put into the compression process, which is also recovered as heat.

Then you can also still use the compressed air to lift the cooling water. In the process of lifting the hot cooling water the heat re-expands the air providing additional lift for greater pumping power.

This is not that different from my "Stirling turbine":

viewtopic.php?p=1190&hilit=Tesla#p1190

The air-lift to drive fluid through a turbine is innovative but as it states in the previous article:

“The key to our system is collecting energy in the air and converting it into electricity,”

“We have a heat pump that is 300% more efficient than the best heat pumps on the planet,” Maynard said. “We spend 50% less energy to compress air than a normal compressor, and we capture 100% of the heat in the process.”

I've said for a long time, the key to these systems, going back to Tripler and Gorrie and others, all the way back to the late 1800's is to cool the gas AS it is being compressed. Simultaneous cooling and compression.

An "air-cycle" system is just a type of heat pump using air as the refrigerant.

By compressing the air, you get back all the heat and work, then you can still use the compressed air to drive a turbine that produces power output in itself, but this also puts out very cold air from the turbine

So you can then use all that extracted heat AND the cold air for the ∆T to run a Stirling engine/generator as well as the air compressor.

All the energy to run the compressor is recovered as heat to run the Stirling engine

This "Flooid" system looks like just another application of the same concept.

Personally I doubt there is much, if any advantage to the, basically muddy water. "“The key to our system is collecting energy in the air and converting it ..."
