At Winds of Change, they've posted an extensive series of links about advances in alternative energy. Lots of good stuff over there, you should check it out. Especially interesting to me is the piece about plasma energy experiments at Sandia National Labs, which (IIRC) I've mentioned here in the past. Also interesting is that Honda is apparently researching home cogeneration units, including one that can refine hydrogen. Honda is perhaps interested in establishing a market for hydro-cars, whether the infrastructure is in place or not. Good for them.
My general optimism about our energy problems continues unabated. The trick is getting people to take the initiative in using all this good stuff.
