Wired News: The Hydrogen Gold Rush Is On: "Livingstone isn't the only person with a scheme to save the world through hydrogen. The last two years has seen a boom in hydrogen investment. In 2003, President Bush announced that the federal government would invest $1.2 billion into hydrogen over the next five years. General Motors has said it is spending at least a billion dollars on hydrogen and fuel-cell technologies, and companies like BP, Chevron and Shell are also making significant investments.
All that money has spawned a gold rush of inventors, all seeking the mother lode of cheap hydrogen. There's plenty of fool's gold in the dash for the moolah, and marvelous hydrogen inventions are shaping up as the perpetual-motion machines of a new age."
