Actor Dennis Weaver, environmentalist founder of The Institute of Ecolonomics, puts the pedal to the metal to lead a convoy of hybrid and alternative-fueled vehicles on a cross-country journey from Los Angeles to Washington, D.C., to promote clean-burning, renewable energies that could promote a decrease in U.S. dependence on fossil fuels.

Today, it’s about cutting-edge vehicles powered by hydrogen, electricity, compressed natural gas, biodiesel, methanol, and ethanol. For information, log on to www.drivetosurvive.info.
