I found this interesting article today about an electric car manufactured by Tesla Motors Inc. They already have a car on the market, but their next model, called the Modesl S, is supposed to go on sale in the third quarter or 2011, and can go about 260 km on one charge.
It looks like electric cars are going to be more economically viable than hydrogen, at least for the time being. The Tesla Motors website also has a nice mix of English and (sometimes incorrectly labeled) metric units. When they list power in kilowatts, it's sometimes abbreviated "kw," and on the performance specifications page "newton-meters" is abbreviated "nm" and "foot-pound" is abbreviated "ft/lb."
