the hydrogen thing

[sparkSubscriber]

Hi;

There are some technologies, just not very well known.
For example the solar-hydrogen fuel cell system for a
solar-hydrogen home .
And this is an existing technology.

With photovoltaic solar panels electricity is generated,
and it is used for producing hydrogen gas. Compressed
hydrogen gas is stored in tanks and used later to
generate electricity with a fuel cell.

And even more:
The Duffy Voyager
a custom solar-hydrogen racing boat on track to break
all ocean going speed and distance records.
The system will produce hydrogen on board, as needed,
creating no emmissions.

May be one more idea:

 

The generation of photovoltaic electricity probably has to be on the surface of the

water in ocean conditions, because the sunlight does not  go far into the water.

 

When the electrodes are very deep in the wated (3000 meters) with a long cable

from the surface form pv solar panels, the forming bubbles are already compressed

quite a bit.

 

Well;

may be.

 

This could be tested too.

Or developed.

3000 meters depth = 300 bar counterpressure

that wouldn’t really work, as if you had cables that are so long, you’d need very high voltage, and likely even alternating current, to get any of that electricity to the other side,  besides that you might have sharks attacking the cables, as they are electro-sensitive.

Much better off producing and storing hydrogen on the boat, there are ways of compressing it passively, for instance by using it to pump barrels of water upward and such.
