Last week, in the post "Six (Or 7) Ways To Power A Vehicle With Wind" I left out a super-fast land yacht now waiting for perfect weather in Perth to try to set a world record in wind-powered land-yacht speed (didn't even know there was one of those, did you?)
Ride Like The Wind, Greenbird
Engineer Richard Jenkins has built the Jetson's/Forumula 1 version of those wind-powered vehicles right now racing the beaches at Race Aeolus 2008 in the Netherlands. Jenkins' craft, named Greenbird, now has a sponsorship deal with U.K.-based Ecotricity and sports its logo, and Ecotricity's managing director will ride along when the wind and the weather gets good enough near Perth for the record-breaking attempt (the previous 1999 record is 116.7 miles per hour).
Vertical sailing wing, rather than a turbine
Instead of a turbine, either vertical or horitzontal, Jenkins' craft has a rigid vertical wing like an aircraft's wing, which theoretically allows it to travel at six times the speed of the wind. Jenkins told the Guardian:
"Top speed is actually quite scary. The structure and tyre grip is all at the limit, so keeping it in a straight line under full control takes full concentration."
Jenkins has a quest to become the fastest naturally-propelled human, which may not help those of us just wanting a reliable vehicle that uses a sustainable, renewable source of power, but it is still a bit thrilling. Jenkins will also pursue a naturally-propelled ice speed record in Montana this winter. Via ::The Greenbird Project
