Sorry, this is more like a comment.

Good point Pup and Ko on both fronts. Something else to consider...fuel cell technology.... Research aside, why hasn't this taken off yet? The SUV is such a marketable commodity for all...car companies, insurance companies, oil companies, finance institutions, etc. Yet there is no more research to be done on the damn thing. So why not stunt our growth in science and technology so we can all be placated by our gas guzzling Explorers?

Sure, several automobile companies have developed concept cars relying on alternative energy sources but at what economic risk? Auto researchers aren't given a blank check. Instead they're told to volunteer. Oh, there's funding, but W will be sure nothing’s happening to oil companies no time soon... The $720 million proposal is to develop an alternative fuel that still relies on oil...WTF? Spare me the charity.

As is always the case progressive thinkers are reduced to beggars...
