Now I am going back to my Engineering school chemistry here so:
It depends on the voltage and current used
In Salt (NaCl) the Chlorine atom is more electronegative than the Oxygen
atom in the water in that the Chlorine atom holds on to its electron
tighter than water.
It the electrolysis process.
Oxygen is stripped away from the Hydrogen forming Hydrogen gas and
Oxygen gas.
If the voltage and current are high enough the Chlorine is stripped away
form the sodium or the potassium (both are in salt water) and collecting
as a a gas on the negative electrode with the Oxygen. The Sodium on the
other hand now reacts with the water stripping the H2O molecule of a
Hydrogen atom to make Na(OH) plus a single Hydrogen atom. This atom
will migrate to the positive electrode to produce even more hydrogen
than the electrolysis of water. So the whole process becomes even more
efficient.

Not if you count the ice at the north and south poles as fresh water
which it is....

Like every thing else you post it is flat assed wrong....
