Bid for world land-speed record | |
(about 3 hours later) | |
Two British men are preparing an attempt on the world land-speed record for a wind-powered vehicle. | |
Eco-entrepreneur Dale Vince and engineer Richard Jenkins will try to beat the record of 116mph (187kmph) at Lake LeFroy in Western Australia. | |
Their British-designed and built craft, named Greenbird, is carbon-neutral. | |
Gloucester-based Mr Vince said they were following in the footsteps of Donald Campbell whose Bluebird they drew inspiration from for the name. | |
"Campbell did it with the prevalent fuel of the day - we're doing it with the prevalent fuel of tomorrow," he said. | |
"Donald Campbell had his massive cubic capacity engines and energy dense fossil fuels - we have just the wind. | "Donald Campbell had his massive cubic capacity engines and energy dense fossil fuels - we have just the wind. |
"But the wind will still be here in 50 or 100 years time - the age of renewables has been a long time coming (back) but will endure." | "But the wind will still be here in 50 or 100 years time - the age of renewables has been a long time coming (back) but will endure." |
The Greenbird relies on solid sails like an aircraft wing. | The Greenbird relies on solid sails like an aircraft wing. |
'Wind window' | |
In the same way that air flows over an aircraft's horizontal wing and pushes the aircraft up, the flow of air over the Greenbird's vertical sail pushes the vehicle forward. | |
This force enables the craft to travel between four to six times the real wind speed, depending on the surface traction. | |
Mr Vince who will co-pilot Greenbird said he was "eight out of 10 confident" of breaking the record. | |
"We need the weather to come right, the lake is wet at the moment and it should be dry this time of year and we need the wind window which is coming any day now," he said. | |
"The lake is 500 sq km and is a salt lake so it's very flat and we can sail in any direction. It has some good wind as well but it's really the space we need." | |
The team also plans to make a challenge on the Ice World Speed Record, again using wind power alone. |
