ahem, A water molecule is two parts hydrogen and one part
oxygen.
Therefore separating the parts gives us two whole hydrogen atoms to
excite and extract energy from. I have read that Hydrogen is
approximately 10 times more unstable than gasoline and therefore you
need less of it to create the same amount of explosive force.
Yes. And splitting H2O to H2 + O takes at least as much energy as you get from
bunring the H2 to H2O! That is a fundamental law of the universe we live in!
So H2O is a good battery. But its not a fuel. And you need energy to split it
up so it burns. And in cars this energy is better used to directly drive a
motor, not only because you loose energy in the H2O -> H2 + O -> H2O -process
but also because the combustion engines have a bad effectiveness compared to
direct electrical motors.
The only reason why they try to develop hydrogen-cars is because it could be
easier to carry the hydrogen (note: not water but hydrogen) instead of big
chunky batteries...
Now back to my system-setup and music-making and maybe even working...

Scientists aren't sure of that! Because ice has a lower density then water,
one volume-unit of ice is bigger than the same volume-unit of water. So if
the ice-caps melt and there is no ground underneath, just ice and water, it
might very well be that the sea-level goes down instead of up!

you only have to wait
for the rain or go to a lake/ocean whereas electricity is slightly more
complex to attain and usually requires payment for the privilege.
Are we living on
the same planet ? In most places water supply will
become as big a problem as petrol supply. Anyway I don't see this issue as I live in a
tropical part of the world
and have a big river 10 minutes walk away. Also the Ocean is only 2
hours drive away.
Try to explain that to people in the middle of Africa, in the tundra, in the
Chinese landsite, heck, even here in germany there are regions that are
really dry compared to "big river 10 minutes away".
And you will notice that the water of the ocean is _not_ suitable for these
alternative engines per se. It needs to be cleaned and de-salted...
That is another reason why melting the icecaps doesn't help with the
water-needs: the water we get is salted.
If you can burn water directly without having to
extract the hydrogen
first
But you can't since it is already 'burned'. It's the
'ashes'
of burning hydrogen.
