General Motors is building a prototype for a home hydrogen refueling unit in hope of selling fuel-cell cars by 2011. According to USA Today, 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."
