Dutch, you might want to look at how the government works and how taxes are spent. You can't simply divert money for the military to other things. Also the 'free fill-ups' don't answer one MAJOR problem... How will we pay for road repair and construction? Tax money from fueling your car (be it with gasoline, ethanol, whatever) is taxed and that money goes to paying to fix the roads we all drive on. Eliminate that tax and you have a major problem with roads. Also, last time I checked (about 4 years ago while I was taking classes in alternative energy) solar energy still isn't that efficient. I will admit I think its a great idea, but there are many problems with saying that they expect to have 98% of the US covered by 2015. First and foremost, less sun = less power, meaning that on cloudy days and in the winter you won't be able to drive as much. Also, for those that live in states that get a lot of frost, this means daily scraping frost off your car windows and solar panels, since to maximize the amount of sun you get you wouldn't want to park your car in a garage. As of right now, on half charge, I believe you can get maybe 60 miles... Know any good landmarks you want to visit within an hour drive of your home? Also, 20-30 minute charge would be more like 1/4 to 1/8 charge at current technology, not 1/2.
As I said, they have a great idea, but for right now their ideas are far outstripping the science they need to make it real. I'd love to see solar cars (if we could find a way to maintain roads without raising taxes on other things to pay for them), but I don't see it truly happening before 2020 at the very least.
