Toyota Prius As A Generator

June 12, 2007

“The Prius, unlike the generator, also has a battery that provides instant, UPS-like power, to your house.  Careful research has shown that most* people would prefer not to go outside to manually pull a cord in the case of a power failure.  The same independent research foundation,** using accepted methods of sampling and polling***, determined that most* people would prefer not to spend money on a big, expensive generator, even if they don’t have to pull on the cord.”

Power via Wireless

June 7, 2007

“Massachusetts Institute of Technology researchers made a 60-watt light bulb glow by sending it energy wirelessly – from a device 7 feet away – potentially heralding a future in which cell phones and other gadgets get juice without having to be plugged in.The breakthrough, disclosed Thursday in Science Express, the online publication of the journal Science, is being called “WiTricity” by the scientists.

The concept of sending power wirelessly isn’t new, but its wide-scale use has been dismissed as inefficient because electromagnetic energy generated by the charging device would radiate in all directions.”

Turn Waste Heat Into Electricity Using Sound

June 4, 2007

“University of Utah physicists developed small devices that turn heat into sound and then into electricity. The technology holds promise for changing waste heat into electricity, harnessing solar energy and cooling computers and radars.”We are converting waste heat to electricity in an efficient, simple way by using sound,” says Orest Symko, a University of Utah physics professor who leads the effort. “It is a new source of renewable energy from waste heat.””
