Alternate Fuels

Great article (from Popular Mechanics) covering the various alt fuels, their pros and cons, and the likelihood of wide-scale development. While I'd like to see additional domestic production and refining capacity built, some of these ideas have had, and will continue to have, an impact on the nations' energy needs, particularly biodiesel and ethanol. I'd like to see a similiar articles on tar sand/oil shale developments and methane hydrate nodules. Of course, I'd like to see some new pebble-bed nuclear reactors built in this country, too, but I'm not holding my breath.
