GM developing home hydrogen refueling device

General Motors is building a prototype for a home hydrogen refueling unit in hope of selling fuel-cell cars by 2011.
The unit, which would make hydrogen using either electricity or sunlight, would help sidestep one of the most vexing problems surrounding the creation of the pollution-free, alternative-power cars: how to persuade oil companies to invest in expensive new hydrogen stations that would compete with their core product, gasoline.
