It’s taken 10 years, but Richard Jenkins has at long last achieved his dream of setting the land speed record for a wind-powered vehicle. The British engineer climbed into the land yacht he calls the Ecotricity Greenbird and peeled off a 126.1-mph run across a California desert Thursday to take his place in the record books.

Instead of a conventional sail, Greenbird uses a rigid wing that produces thrust in much the same way an airplane wing produces lift. The vehicle is made entirely of carbon composite materials, and the only metal parts are the bearings for the wing and the wheels. Jenkins says the aerodynamic design and light weight lets Greenbird achieve vehicle speeds three to five times greater than the wind speed. An earlier prototype once hit 90 mph in a 25 mph wind…
