Hybrids 2.0.

The "Alt Car Expo" is this weekend in Santa Monica. Billed as "The largest presenation ever of electric, hydrogen, natural gas, biodiesel, ethanol, and high MPG cars," the show will feature some models that make the Prius look like a 1972 Chevy.

The agenda is heavy on policy discussion too, with presenations by Terry Tamminen, Ed Begley, JR., former CIA boss James Woolsey and Fran Pavley. Topics will include "alternative fuel technologies, tax credits, transportation solutions and more..."

Admission is free so if you're in LA this weekend and already have your Christmas shopping done, you might check it out.
