The Power of One

The Power of One is a solar powered car setting a new distance record for solar powered cars. I don't know what the new record is, because the car has not stopped yet, but it's already well over the old record. On August 2/09 I learned that Marcelo has returned to Inuvik, NW Territories and has driven 22,151 miles on solar power alone, so far. He's looking for a sponsor so he can drive to the southern tip of South America! Let's hope he makes it.

Power of One has arrived in Alberta (6/26/09), and has driven over 18,000 miles using only sunshine as fuel, never being plugged into the grid, crossed the continental divide 8 or more times, driven on over 1200 miles of gravel roads, taken on snow, ice, and the low angle of the Northern hemisphere during the wettest summer of the past 30 years in the region.

From Toronto to the Artic circle and then to California, Florida, DC and back to Canada, an incredible adventure. A true demonstration of the power of solar energy.

Dream of Marcelo da Luz of Toronto, Canada, the Power of One has rolled a long way. The top of the car can be raised and tilted to point at the sun when stopped.
