A CRUSADE for cleaner air is to see the world's first emission-free taxi take to the streets of London at the end of this month. And its fuel running costs are boasted to be almost a third of the price of rival diesel black cabs.
Space-age alternative fuel technology is the secret behind the revolutionary hydrogen-powered vehicle costing £27,500. The Zevco Millennium cab looks like many other black taxis in the capital, but rather than throwing out choking fumes the only thing the vehicle will produce is water vapour.
Under the bonnet is an alkaline fuel cell generating electricity to drive the cab. The fuel cells breathe in oxygen from the atmosphere and combine it with hydrogen gas carried in a tank under the floor. Cobalt and platinum catalysts within the cell react with the gas to produce electricity.
Zevco says the cab will cost about £6 a day to run, compared to the £15 a day diesel bill and £12 a day gas power needsThe taxi, which has a range of 300 miles and a top speed of 60mph, will be taking to the streets of Westminster on July 30.
