What will be the USA reaction if communist China attacks Taiwan 540

The hydrogen economy thing is another NEOCON red herring. or maybe even far worse.. .. read on..

Since there is very little free Hydrogen gas (H2) available on this planet. It must be manufactured from other compounds and energy sources.

The well known energy conversion losses of the hydrogen gas manufacturing process negates any savings promised by fuel cell tech.

Furthermore large scale usage of Hydrogen gas and the resultant H2 leaks could wipe out what remains of the ozone layer (O3 + H2 == H20 +O2) and collaspe-wipeout the food chain..

Est H2 leakage-yr.. we will choose the low end of the estimate or 60Tg-yr or 6x10^13g-yr see..

"Atmospheric Effects of a Hydrogen Economy"

Global ozone mbutt 3x10^12 kg or 3x10^15g see.. "A New Zealand perspective on global ozone"

---- Chemical reaction calcs ----.

Ok.. adjusting for atomic weight... Total atmospheric Ozone world wide. 3 x10^15g * mole(Ozone)48g == 6.25x10^13 moles of Ozone.

Estimated release of H2 from Hydrogen economy.. 6 x10^13g *mole(H2)-2g == 3x10^13 moles of H2 released per year.

Adjusting for chemical reaction quoted above. min(3x10^13, 6.25x10^13) == 3x10^13 moles.. or ~48% of ozone layer converted to water vapor in a single year.

---- summary ------

Now. 48% per year is a very scary number. Notes: That was using the low end of H2 leakage rate estimate.. High end leakage rate is double that. Caveats ..the actual reaction rate will be a little lower since not all H2 gas will make it into the stratosphere, and not all H2 will react with 03.. but..

That figure represents the end of most life on Earth, I.E. No ozone layer == the apocalypse.

Who would have though, that El-bushie and his NEOCON friends had such lofty goals?

Unfortunately, You may just get your wish granted.

After a billion years or so.. Evolution should be able to deliver a replacement sentient species.. (Complete with new batch of oil reserves made out of ???.)
