It's in technologies like GE's low-cost electrolyzer that the automakers must be setting their highest hopes. The system, which will likely be christened with a catchy, techy name soon, used a high-tech plastic called Noryl to produce a kilogram of hydrogen for about $3 instead of the $6 or $8 it currently costs. The system's lead engineer, Richard Bourgeois, sees a time when hydrogen filling stations won't need a fuel delivery. They'll just make their own fuel.
Other transportation winners include the Gyro Bike and the Lexus LS 460's autopark feature (which to me gives a bad name to the other winners, considering what I've read on the feature being more hassle than it's worth).
