Alternative fuels: I meant to post this earlier today and Eno's post about the cost of gasoline reminded me. It's a review of the various types of alternative fuels by Popular Mechanics. Ethanol, Methanol, Biodiesel, Hydrogen, Electric. Pros and cons of each and their outlook. It's a good, unbiased look at each, though it's not exactly in depth on each.
