Solar-Powered Biodiesel Pump
07 June 2005
The Santa Cruz Sentinel reports on the opening of a solar-powered biodiesel filling station in Santa Cruz County, California.
Both graduates of Soquel High School, Roussopoulos and Rubalcaba restored a red, 1939 gas pump with new measuring equipment, solar panel, hand-painted sign and 1,000-gallon fuel tub that looks like a giant whiskey barrel.
An old airplane propeller keeps the fuel from frosting at night.
Roussopoulos assembled it all himself, he said, for between $5,000 and $6,000.
The new pump at Mountain Feed and Farm Supply sells B100 for $3.71 per gallon.
