This idea is NOT about perpetual motion or anything of the
sort.
Pipe inserted in sea in a horizontal diagonal position, so: /
Seawater enters the bottom. Turns a turbine in the middle.
The turbine serves as a dynamo or powers an electric
generator.
As the water passes through the
turbine, it generates
electricity sent to two electrodes causing electrolysis.
Bubbling upward (separately) the gasses will cause a steady
flow of water upward, which continues to power the
turbines as an air pump does (see link)
If a sufficient percentage of power is returned to the
process, it:
1. May cause the process to be steady and continuous,
despite the changing power of the sea currents.
2. May even be of practical value (I'm thinking 20% or
more...)
Is there a way to figure in advance how much energy can
be retrieved from this?
-----
Some extra thoughts to be discussed only if the main idea
isn't debunked:
Possible additions:
1. The turbine itself serves as the set of electrodes - either
the rotor is one electrode (say anode) while the stator is a
different electrode (say cathode), or the rotors are built of
an anode and cathode with some electric insulation
between them.
2. Water and gas emit from top of pipe from an exit
thinner than the entrance to the pipe at the bottom,
causing a "venturi effect" for the sea current.
3. The oxygen can be emited on the peripheral of the pipe
while the hydrogen at the center of the pipe. Above the
emition of hydrogen an extra pipe can be inserted within
the main pipe, keeping the gasses separated
