The electric car and all other powered things that don't depend on foreign oil are the hope of the future. If you like the idea of having to kneel down on a prayer rug 5 times a day to worship a false god and those who control the worship, keep preaching that gas and oil will never be replaced. My main concern is lower costs and independence from the Arabs. Although your comment about battery production might be a valid point, when compared to the alternative, oil refining, it's lame.
Every time someone posts a thread about alternative energy sources, the same crowd shows up to throw rocks. What are you afraid of?
