LONDON, Jun 07, 2010 (BUSINESS WIRE) -- Intelligent Energy, Lotus Engineering, LTI Vehicles and TRW Conekt, with funding from the UK Government's Technology Strategy Board, today unveiled a full performance, zero-emissions Fuel Cell Hybrid London taxi. While the taxi looks and drives like an iconic London black cab, the Fuel Cell Black Cab is powered by an Intelligent Energy hydrogen fuel cell system hybridised with lithium polymer batteries; allowing the vehicle to operate for a full day without the need for refuelling. Capable of achieving a top speed of over 80 mph, it has a range of more than 250...

A new catalyst that generates hydrogen from sea water has been developed by scientists in the US. This new metal-oxo complex displays high catalytic activity and stability, whilst being low cost, the researchers say.Hydrogen is very attractive as a clean source of power. Currently, it is produced by natural gas reforming - where steam is reacted with methane in the presence of a nickel catalyst to form hydrogen - but this method produces the greenhouse gas carbon dioxide.Jeffrey Long and colleagues from the University of California, Berkeley, prepared a simple molybdenum-oxo complex that can serve as an electrocatalyst, reducing the energy required to generate hydrogen...

Hydrogen fuel-cell technology has made significant progress, but it will still be some time before cars fuelled by hydrogen will be affordable, Arturo Elias, president of General Motors of Canada Ltd. told reporters Wednesday. GM -- which was showcasing its fleet of eight hydrogen-fuelled cars the company is using during the Olympics -- has said in the past it hoped to commercialize a fuel-cell vehicle by 2015. "But there are some challenges," Elias said. Those challenges include ensuring the infrastructure for refuelling is in place and lowering costs. Hydrogen-fuelled cars are electric cars that get their power from hydrogen rather...

Science fiction writers may have to rethink how their starship crews survive travel near or beyond the speed of light. Even the occasional hydrogen atom floating in the interstellar void would become a lethal radiation beam that would kill human crews in mere seconds and destroy a spacecraft's electronics, New Scientist reports. Just a few stray wisps of hydrogen gas -- fewer than two hydrogen atoms per cubic centimeter on average -- would translate into 7 teraelectron volts for a starship crew traveling at 99.999998 percent of the speed of light. That's as much fun for humans as standing in...
