IT'S ONLY A matter of time before we start seeing hydrogen-powered bikes on our roads and here's the latest thinking of the concept from France.Design students at International School of Design (ISD) at Valenciennes have concocted a machine using

INTELLIGENT ENERGY, the British-based technology company, and Suzuki have unveiled the Crosscage - a hydrogen-powered motorcycle. The bike is virtually silent and emits pure water, rather than noxious exhaust gasses associated with internal

OXFORDSHIRE-based company Cella Energy is developing a fuel that could be used instead of petrol and would cost just 19 pence per litre.The fuel uses hydrogen and is described by Cella energy as 'the perfect fuel' as it produces three times as much

Suzuki's hydrogen-powered Burgman scooter has become the world's first fuel-cell vehicle – regardless of the number of wheels – to pass European Whole Vehicle Type Approval tests.Developed in the UK with British firm Intelligent Energy, the fuel

, Mr Honda San, argues that this would have compromised the scooter's practicality in terms of weight, bulk and storage. Hydrogen fuel cells were discounted because they just aren't small enough yet.Back in an hour or two with some whisper-quiet video...

or precious little anyway. Forget the alternatives as well. We don't have a hydrogen fuel distribution system in place. Bio-Ethanol is a touchy subject, too, especially bearing in mind rocketing global food prices. It takes land to grow the crops to produce
