Garage Invention Turns Restaurants Into Power Plants

Would you like power with those fries?
A new garage-engineered generator burns the waste oil from restaurants' deep fryers to generate electricity and hot water. Put 80 gallons of grease into the Vegawatt each week, and its creators promise it will generate about 5 kilowatts of power.
That's about 10 percent of the total energy needs of Finz, a seafood restaurant in Dedham, Massachusetts, where the first Vegawatt is being tested. At New England electricity rates, the system offsets about $2.50 worth of electricity with each gallon of waste oil poured into it.
Vegawatt's founder and inventor, James Peret, estimates that restaurants purchasing the $22,000 machine will save about $1,000 per month in electricity costs, for a payback time of two years.
"You take this waste resource and make it a profit center," said Peret, who spent four long years cooking up the project in his garage. "When I started telling people, they said, 'Someone's gotta have done this.' I'd run into more people. They'd say, 'Why hasn't anyone done this?' My only response was, 'I don't know; it seems like a good idea.'"
