It's no wonder inventors are racing to develop the best type of engine to power tomorrow's fleet of hybrids as automakers rush to get enviro-friendly cars on the road and consumers are tempted by a new $7,500 tax incentive being offered for buying one. But it's not only new inventions that are vying for a piece of the action: Microsoft co-founder Bill Gates, former Microsoft chief technology officer Nathan Myhrvold, and other entrepreneurs are attempting to put a new face on technology that's been kicking around for more than a century—an electromagnetic engine that turns mechanical into electrical energy.
The U.S. Patent and Trademark Office last week published a patent application describing an internal combustion engine that "converts mechanical energy of a piston to and from electrical energy during each piston cycle" submitted in October 2007 by Searette LLC, part of Intellectual Ventures, a Bellevue, Wash., company launched in 2000 to buy and license patents. Gates, who was still Microsoft's chief software architect at the time the patent was filed, is listed as one of 10 inventors on the application.
