Huck,
In my humble opinion, Flex-fuel or H2 are the growing technologies of the next 10-15 years. Flex-fuel or bio-diesel are the only two oil alternatives that are going to work short-term, as H2 is going to be a long, long way from anything like a HUMMER (unless you don't mind filling up every 100 miles). Gas will likely go up as China, India, and other countries expand, and as the oil-wealthy nations continue to be unfriendly. Some of the only near term solutions are:
1. Discover more oil domestically (highly expensive)
2. Blow the bits out of those countries and set up our own infrastructure (highly expensive and slow)
3. Grow our own fuel (Think Brazil; very possible as the distribution networks are there, and we're familiar with liquid fuels)
4. Stop driving
It's not really an environmental issue (though there are environmental benefits when using switchgrass or sugar cane), but simply (I think) the changing nature of our world and economy. Personally, whatever I drive next I want to have flex capability because it's coming, even if it's not here today. Though corn has to go away as the production source.
Anyway, back to the gloriousness of the H3 ALPHA!
