Cowboydoc, it's very seldom I disagree with you. There are renewable, environmentally friendly fuels out there but I can't think of one that is a "cheap" alternative to oil. If oil hits a $100/bbl then they will become much more viable but in that case who do you think will control them ... the oil companies. Most of the research into alternative fuels, fuel cells, solar, etc., is funded, one way or another, by the major oil companies or the government and we all know that the government doesn't do much. When this country and the world changes from their hydrocarbon based economies it'll most likely be to some system and technology developed, owned and controlled by the oil companies. They're not going to be like the horse drawn carriage maker, sitting by the side of the road watching the Model "T" driving by. They're a lot smarter than that. Back in the 50's, 60's and '70's, when it looked as if nuclear was the way of the future who do you think was the largest producer of uranium in the country, if not the world .... Mobil Oil. If anything does threaten the position of oil that they haven't had a hand in developing, they'll simply buy it and take it over because they can't afford to be left behind and they have the resources to do it. They don't have to suppress it either. They'll run it in addition to their oil business. As the reliance on oil decreases, the reliance on the alternative energy will increase. Either way, they'll maintain their position in the pecking order. I'm sorry, but whatever form of energy we use going forward, we'll still be dealing with the ExxonMobil's, Shell's, Chevron's and BP's of this world. I just don't see any way round it but I would like to see control of our energy supply and use come back to this country. It'll be interesting going forward but OPEC isn't stupid either. I can't see them allowing the price of oil to rise to such an extent that any alternative fuel will become too big a threat. They have to walk a thin line between raising the cost of crude to such an extent that the Western economies go into recession leading to reduced demand and falling prices and raising it so high that alternative fuel become vaible. Now that they've seen that $60+ a barrel oil hasn't hurt the major economies, don't expect any sharp drop in prices in the near future.
