KEY POINTS:
Two British alternative energy enthusiasts are waiting for a West Australian lake bed to dry out as they prepare for an attempt on the world speed record for a wind-powered vehicle.
Company director Dale Vince and engineer Richard Jenkins hope to beat the current record of 187.77 km/h with their craft, Greenbird, on the salt flats of WA's Lake Lefroy, about 50km south of Kalgoorlie.
The record has stood since March 1999 when Bob Schumacher reached 187.81km/h mark on a dry desert lakebed at Prim, Nevada.
