skyhawker writes "Yahoo! News is running an article about a New Jersey home that uses solar power to provide 100% of its energy needs, including fuel for the owner's hydrogen fuel cell-powered automobile. From the article: 'Strizki runs the 3,000-square-foot house with electricity generated by a 1,000-square-foot roof full of photovoltaic cells on a nearby building, an electrolyzer that uses the solar power to generate hydrogen from water, and a number of hydrogen tanks that store the gas until it is needed by the fuel cell. In the summer, the solar panels generate 60 percent more electricity than the super-insulated house needs. The excess is stored in the form of hydrogen which is used in the winter -- when the solar panels can't meet all the domestic demand -- to make electricity in the fuel cell.'"
