A friend of mine sent me an invitation to a webinar called the “Roadmap to a Hydrogen Economy and Review of Alternative Energy Technologies.” I hope he doesn’t regard my response as indelicate or ungracious:
Thanks! I’ll try to check this out, even though I’m in complete disagreement with the thesis, for two reasons:
1) The idea that “The planetary fossil fuel system will be replaced by a transition to a hydrogen based system” is false. We’re going to retrofit our 3.5 million square miles (of the continental U.S.) with a delivery system for hydrogen? Not in a million years.
2) That the idea is impractical is only part of the problem; it doesn’t make any sense. It’s like saying “we’re replacing gasoline with steam or compressed air.” OK, there is chemical energy in gasoline that can be released, but there isn’t in water or air. Where’s the energy going to come from to evaporate the water or compress the air? If you want hydrogen, where’s the energy going to come from to, e.g., electrolyze water?
