Shell says ethanol knocks down CO2 big time

Dunno, haven't really studied it. But if you've got a bunch of wind turbines running at night, producing more than you can use, is catalyzing hydrogen that much less efficient than charging batteries, pushing water uphill or spinning a massive flywheel to try to store the energy for the next day? If "all the wind is concentrated in the flyover states," as the anti-AE crowd says, then rather than trying to transmit it thousands of miles across wires, why not make a liquid fuel that can be used in local transportation?

Even those who suggest population control agree that with wealth and choice comes a reduced level of population growth.

Because to make a liquid fuel out of hydrogen, you have to cool it to -423F? See Liquid hydrogen - Wikipedia, the free encyclopedia
