"A concept car that attempts to sidestep the three main hurdles to the dream of hydrogen-fuelled highways was unveiled in London, UK, today. Like other hydrogen cars, the Riversimple Urban Car (RUC) is powered by a fuel cell that combines hydrogen with oxygen from the air to release energy and nothing more toxic than water. Its makers claim that by starting from scratch to build a small, efficient car they can make it commercially viable more quickly than the major auto manufacturers experimenting with adapting more conventional cars to hydrogen. Honda predicts its FCX Clarity hydrogen car will enter mass production in 2018, but Riversimple is aiming to lease its first fleet in 2011 and mass produce in 2013." - Steven Perez from Bookmarklet

Makes no sense. Why not just put a battery in there and skip out on all the hydrogen stupidity? - Wirehead

Electricity still needs to come from something else. Hydrogen is an abundant source in itself. Yes, there are complications, but it's the same as the search for cold fusion. The potential gains in clean and cheap energy are too good not keep trying. - Michael W. May

Where are the hydrogen mines? Hydrogen either is manufactured from water at a net energy loss from centralized generation or from existing fossil fuels. It is not an abundant source. For the most part, you might as well just leave the carbon on the natural gas and charge a battery. - Wirehead
