Hydrogen powered Shelby Cobra

Although its usually the last place to get good info, I saw an article in the LA Times this mornign that Shelby, while building his new line of Cobras (the AC kind, yes he's remaking them too, yes he's a money grubbing whore, thats beside the point) which retail in the 80-100k range, he's also making a hydrogen powered version that will retail int he 150-170k range. The article said the top of the line hydrogen car would have 400 hp, and that they were all V8s, they just ran on hydrogen instead of gasoline. It would also get 25 mpg, albeit only having a 4 gallon tank.

I, looking beyond the price, realized that if they can stuff a hydrogen V8 in an original style Cobra, they can definitely do this to Mustangs... so in 10 years when we all run out of gas and hydrogen engines aren't so outrageous and probably will make more power, I can just drop a hydrogen V8 in my car... yes, i'd rather drive a gas powered, original style v8, but... at least my car wouldn't have to rot away...

Another factor is that Shelby automobiles, though they might have had help from other companies, is a small companyw ith limited R&D capability.. if they could do it, a major company could do it much cheaper...
Thoughts?

thats what the times said... and while i was sorta exagerrating with the 10 year claim, most estimates i see are in the 30-50 year range, and with the newfound love for SUVs and performance and the fact that we are just now starting to tap the massive asian market, i don't really think that the number will be growing..
