Two British men are preparing to break the world land-speed record for a wind-powered vehicle. Two British men are preparing an attempt on the world land-speed record for a wind-powered vehicle.
Eco-entrepreneur Dale Vince OBE and engineer Richard Jenkins will try to beat the current record of 116mph at Lake LeFroy in Western Australia. Eco-entrepreneur Dale Vince and engineer Richard Jenkins will try to beat the record of 116mph (187kmph) at Lake LeFroy in Western Australia.

Gloucester-based Vince said they were following in the footsteps of Donald Campbell whose Bluebird they drew inspiration from for the name. Gloucester-based Mr Vince said they were following in the footsteps of Donald Campbell whose Bluebird they drew inspiration from for the name.
The founder of Stroud-based renewable energy supplier Eco-Tricity said: "Campbell did it with the prevalent fuel of the day - we're doing it with the prevalent fuel of tomorrow. "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."

In the same way that airflow over an aircraft's horizontal wing pushes the aircraft up, the flow of air over The Greenbird's vertical sail pushes the vehicle forward. 'Wind window'
This force, combined with exceptional efficiency, enables the land craft to travel between four to six times the real wind speed, depending on the surface traction.

The team will also make a challenge on the Ice World Speed Record, again using wind power alone. 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."
