Forget hydrogen. The car of the future has an extension cord and a great big laptop battery. The next evolution of the automobile will be plug-in hybrids that get their juice from a household electrical outlet. They'll start rolling into showrooms within in 18 months. Experts say plug-in hybrids could account for about 20 percent of vehicle sales within a decade -- and half of all sales by 2050.
"It all boils down to the three ways electricity is better than gasoline," says Felix Kramer of Cal Cars, a plug-in advocacy group. "It's cleaner, it's cheaper and it's domestic."
Advocates say plug-in hybrids are the best chance to address global warming and wean the nation from oil. Consumers remain unsure about electric vehicles. Ethanol's a shaky proposition because of the food-for-fuel debate. And it'll be decades before hydrogen is a viable option. That, advocates say, leaves plug-ins as the best option. They'll go up to 40 miles on a charge; but they'll also have a gas engine to keep you going beyond that at 80 to 100 mpg or more.
