Sorry dcb,
"Here is a site which suggests that roughly 1/5 as much land is needed to power a car with Algae vs Solar panels: Fat Knowledge: Algae Biodiesel vs. Solar Panels"
I got excited when I saw this because I am a big proponent for bio/diesel aero transportation. It takes 5x the land to power the econo biodiesel versus the sports car EV.
I still think biodiesel is one of the best ways to go. Batteries are heavy, have little range, and are not environmentally friendly (disposal).
