Foolish comments eh? Lets look at solar tech first. Solar as we are doing it now won't work for one very simple reason, the weather. In order to run a large energy grid you need one thing, consistency. Without it, you get brownouts and blackouts. We may incorporate solar someday, but it won't be based upon any ground level collectors. There is only one place where you are guaranteed constant access to sunlight, and that is outside of the atmosphere. At that point, in order to transfer the energy to the ground, you would have to convert to microwave tech or something like it that isn't affected by weather. in order to do that in a cost effective way, you need limited targets, such as existing energy plants. As long as we can convert them so that microwaves produce the steam that turn the turbines, it's possible and in my humble opinion likely. Another alternative is tidal generators, but that probably won't fly for political reasons. In order to place the generators so that they can turn 24/7, you would have to be in International waters. Not likely to happen, what with the save the whales crap the UN believes in. Electric cars will never happen, so put it out of your mind now. Diesel is much more likely to become the standard. Diesel engines are more efficient than gasoline engines, and since the delivery infrastructure already exists, don't hold your breath waiting for anything else anytime soon. In addition, no matter how efficient electric cars become, we still can't use them on a wide scale because most of them would be recharged at night. Our energy grids recharge at night. If everyone bought an electric car and recharged it at night, we'd crash our grids. I'd like to reduce our dependence on foreign oil as much as the next guy, but cutting off your nose to spite your face is ridiculous.
