The Solar Black Bear - Performance Highlights

From June 3 to November 3, 1999, the SSB traveled a total of 2446 miles on $75.60 worth of electricity (based on the utility @ $.14/KW, 414.7KWh). Assuming the price of gasoline to be $1.40 per gallon, a gas-powered car would have to get about 45.3 miles per gallon to compare, or operate at a cost of 3.1 cents per mile of travel.

From June to November 2000, 2001 and 2002 the SBB traveled an average of 50-80 miles per week using only energy gained directly from the sun (about 10-15 miles of free driving per day). It cost literally nothing to drive and produced virtually no air pollution for a period of six months each year.
