HHO/buoyancy motor combo???

If an electrolyzer were place beneath a buoyancy motor, both under water, couldn't the resulting HHO first be used to run the buoyancy motor, then be collected at the top?

A buoyancy motor basically runs on air, which floats up in the water, which drives the buoyancy motor.  The problem with a buoyancy motor seems to be that it takes more energy to pump air to the bottom than you get back out when it floats back to the top.  No overunity.

An electrolyzer, so far, usually requires more electricity be put in than you get out in hydrogen.  Again, no overunity.

But, what about combining the two?  Put the electrolyzer beneath the buoyancy motor.  Use the hydrogen and oxygen, which should float in water, to run the buoyancy motor.  Then, when these gasses reach the surface, capture them and store the hydrogen.

Buoyancy motor drives a generator, generator runs an electrolyzer, electrolyzer releases oxygen and hydrogen into bottom of buoyancy motor, driving buoyancy motor, driving generator, ect...

No air would have to be pumped down to the buoyancy motor, the byproduct of electrolyzing, hydrogen and oxygen, would be produced down there beneath the buoyancy motor.

As for the electrolyzer, 100% of the gas it produces would be used for work---driving the buoyancy motor-- after which the hydrogen would be scrubbed and stored, meaning the hydrogen would be able to work again, this time to run an engine.

I don't know if this would provide more energy than you have to spend to run it, but if you can use 100% of the gas byproduct to make energy before you even scrub and store the hydrogen, wouldn't that change the ratio of energy needed to run electrolyzer vs the energy you get out in hydrogen more in favor of hydrogen production?

Anyway, it might be an avenue worth considering in the quest for "free energy."

Hi
I know nothing about HHO production,or bouyancy motors,but the only thing that comes to mind is would it take more"juice" to make the gas?as it is now under more pressure,being under water.
The same principle would be to sink a bottle of liquid gas,so gaining energy,pipe to the surface,to burn the gas,empty bottle rises to the surface,gaining more energy,but the cost of making the liquid gas?

That's an excellent point about pressure limiting hydrogen and oxygen production in an electrolyzer.  Does anyone know if water pressure affects the output from an electrolyzer?

My thinking was to put the oxygen an electrolyzer releases to work, instead of just letting it go into the atmosphere.  I realized the hydrogen could also do useful work without burning it, allowing it to be collected after it was done driving a buoyancy motor.  To me, it seemed like a way to increase the total amount of work the hydrogen could do while also allowing the oxygen to do useful work.

If water pressure limits production of an electrolyzer, I'm sure a buoyancy motor could be designed that works closer to the surface.  Rather than a buoyancy motor that is set up vertically in water with the bottom of that motor pretty deep, perhaps a horizontal setup just beneath the surface with electrolyzers running beneath it?

In any case, it's just a thought that seemed at home in this place.  I figured that since electrolyzers, by nature, operate in water anyway, why not run one in water beneath a buoyancy motor so both byproducts of electrolysis can be made to do useful work without sacrificing any of the final product, the hydrogen itself.

A gravity wheel and a buoyancy wheel have a lot in common.  Both, so far, require more energy to run than they produce.  With a buoyancy motor, that loss occurs when air is pumped to the bottom of it, due to the fact it takes more energy to pump the air down to the bottom of the motor than is given as the air drives the motor as it rises.  If one is going to run an electrolyzer anyway to produce hydrogen, why not put the gasses through a buoyancy motor first, then collect and store the hydrogen?

It's not something from nothing or even overunity, but it might help offset the energy requirement of producing hydrogen, since the buoyancy motor would contribute power to help run the electrolyzers.

It's just a thought.
