There are catylists that look promising for separating hydrogen from methane. LNG looks like it's to be the preferred source.
We should probably start with diesel-electric hybrids. That plan could be widley implemented in as little as five to seven years using the existing fuel delivery infrastructure.
The other major energy solution is trip reduction through broadband. The first step there is eliminating the Post Office. Homes would then purchase one daily delivery of mail, food, library books...
I think it's doable. Screw your damned trains.
That's a wasteful use of natural gas when there are so many other applications dependent on it's availability. And stripping the hydrogen catalyticly to oxidize it alone loses all the exothermic energy that's released when the carbon is oxidized. Heck, you couldn't possibly find enough methane to substitute for the petroleum we currently import.
Screw your damned trains.
You and Dubya are the ones who are out in the Twilight Zone with Ozone Algore as far as coming up with a sensible alternative.
