Floating on H2O is not an issue. The issue s breaking the water into
hydrogen and oxygen, and dealing with the handling and the efficiency
issues.

There will likely (unless there is a great change in the way that we
currently deal with hydrogen) never be a "hydrogen economy" as the
energy and efficiency issues are not realistic at this time.

It's a nice dream, but reality eventually raises it's ugly head.



Water can be turned into hydrogen and oxygen with a little electricity which
can be produced by solar panels.

You'd be better off storing the solar produced electricity in a battery.

Look at the cycle. H20+electricity to H2 to fuel cell to electricity and
H2O.

Its pretty easy, most high school chemistry
classes do it with pretty basic tools.

But they don't use it to power something.

They have been able to store it and
effectively utilize it but the problem is that H2 is a gas so it has to be
compressed to get enough of it stored to actually do anything.

Part of the inefficiency.

The problems
with using it in cars has largely been the connection from the pump to the
vehicle.

And the lack of much heat energy in hydrogen. The energy density is
fairly low.

There are a potential infinite number of ways to do this and almost
as many ways to store it but it would have to be a standard among the entire
industry to make it work not to mention ever refueling station would have to
have the proper connections. There are several companies that have made
hydrogen powered vehicles and appliances. They reportedly work great but
getting everyone to agree takes a lot of time. In the early 1900's there
weren't gas stations at every street corner but people made due until
eventually they were everywhere. The same thing could be true for hydrogen
it just takes time. Greenland is already using a lot of hydrogen power in
it's homes and electrical generation. Their biggest problem is coming up
with new ways to use it and move it around. Since they are the only ones
doing it then they have to pay a higher price.

“In the first place, we should insist that if the immigrant who comes

shall be treated on an exact equality with everyone else, for it is an
outrage to discriminate against any such man because of creed, or
birthplace, or origin. But this is predicated upon the person’s becoming
in every facet an American, and nothing but an American.
“There can be no divided allegiance here. Any man who says he is an
American, but something else also, isn’t an American at all.
“We have room for but one flag, the American flag. We have room for but
one language here, and that is the English language and we have room for
but one sole loyalty and that is a loyalty to the American people.�
