Water is burnt hydrogen. You can burn ten pounds of coal in a
efficient power plant and make a pound of hydrogen from the juice, and
water. It is nuts to make it from oil or natural gas. The hydro is in
use and there are no more good dam sites. In Iowa wind is supplying 5%
of the juice and they make most of the hardware right here. Hydrogen
is more promising than batteries, but what is going to actually
happen, is gasoline made from coal.

The hydrogen in water is still hydrogen. If efficient methods to
disassociate it from the oxygen are developed, it can be recovered as fuel.
The secret to success is finding the method.

You cannot repeal the law of conservation of energy. And all the
methods for making hydrogen were discovered more than a century ago.
There is no magic. hydrogen is only really good if electricity is
free. Gasoline is about fifteen times as dense as liquid hydrogen, and
that is without allowing for the bulk of the insulation. In compressed
form you can carry a couple of pounds in a 360 cu ft cylinder, such as
the standard size one used for oxygen by welders.

From an energy efficiency standpoint, making hydrogen from water is a
non starter. You can't make coal from carbon dioxide either.
