Global Milestones
  • It may be years before you can buy a Chevy powered by hydrogen fuel cells. Tired of waiting?, Shanghai-based Horizon Fuel Cell Technologies decided to design and market the H-racer, a 6-in.-long toy car that does what Detroit still can't. It runs on hydrogen extracted from plain tap water using the solar-powered Hydrogen Station, and can travel more than 300 ft. in a single fuel-up. The car's miniature scale gives it one advantage over full-size prototypes: since it uses only a trace amount of flammable hydrogen, there's no risk of it pulling a Hindenburg in your living room.
  • Today's hybrids are all basically the same: they're powered by a conventional gasoline engine and drivetrain, or they're running on electric power. The car's computer brain decides which, depending on driving conditions and how much charge you have in your batteries. The Chevy Volt, a concept car, is an aggressive-looking four-door sedan running on what Chevrolet calls its E-Flex platform. The Volt has both a fuel-burning engine -- which can be configured to run on gasoline, E85 or biodiesel -- and an electric drive. But unlike the current hybrids, the internal combustion engine isn't connected to the drivetrain: it charges the batteries. It's a full-on electric vehicle with range-extending capabilities.
