buoyancy cycle: mg where the h is free

[exnihiloest]

electrolysis + fuel cell technology is comming very close to a reversable process. (very few losses when care is taken)

i propose the following buoyancy cycle:

1) Water - a container sitting "low" in a gravitational field.
2) electrolysis to break the liquid into two buoyant gasses
3) tanks to capture these gases placed "high" in said gravitational field.
4) a fuel cell to convert the energy from these gasses back to continue the electrolysis process.
5) a generating mechanism to convert the (free) gravitational potential energy gained during the gasseous stage of the cycle.

sort of a perpetual waterfall.

class dismissed, have a great weekend.

Not perpetual. The energy for the electrolysis is pressure dependant. The higher the glass tubes, the heavier the pressure at the bottom and the more energy you need to break H2O against the pressure. You cannot expect a gain.

I believe that producing HHO under pressure decreases the efficiency of producing said gas.

Actually, it doesn't work like one would think. To some extent HHO
likes to be electrolysed from water under pressure, it takes less energy
then compressing it after the fact...Within limits.

The electrolysis unit can be kept at any pressure under water. Suppose we put one in a submarine?
Imagine water proof copper coil stacks rising miles from the sea floor. We can drive oil drums filled at depth by HHO through them. The oil drums could have huge magnet collars that would generate electrical power in the coils as they rise to the surface. The HHO would generate power through a cell at the surface; The drum would fill with water and generate more power as it sank back down.


This would work in a stationary displacement stack on any scale!.

It would require the approximately same amount of energy, to force a buoyant drum out the door of a
submerged submarine as it requires to sink that same drum from the surface, down to the submarine's depth (unless we let an equal volume of water into the sub as the barrel exits).

All of these links and yet, no clear and straight forward answer, to the question
of what the effect of atmospheric pressure is upon the efficieny of water electrolysis.
