Here's a thought. Global warming is self limited. When we run out of oil we must change to another souce of fuel. Hydrogen produced from water with nuclear , wind , solar sources of energy is the only way to go.

Efforts to use ethanol are useless. It will not eliminate carbon emissions and only delays the inevitable developement of hydrogen economy.

How far along would we be to developing hydrogen fuel and hydrogen infrastructure if we spent 8 BILLION dollars per week since the begining of the Iraq war?

End of rant.
