The vehicle that finally proved it's possible to sail downwind faster than the wind is up for auction on Ebay.
It may lack the looks of a Lamborghini or the sophistication of a Bentley, but for pure eccentric wackiness the Blackbird can't be beaten.
Travelling faster than the wind powered only by the wind sounds like it should break an intuitive understanding of physics.
Rick Cavallaro and John Borton of Sportvision along with the San Jose State University got around the issue by building a super-light main structure topped with a massive propellor attached to the wheels.
The wind blows the vehicle forward and as the wheels turn it powers the propellor that provides the extra thrust.
The ad reads: "This vehicle is used (and wasn't all that pretty even when it was new). Low miles :)"
Using this system the team managed to travel at 2.86 times the speed of the wind powering it.
Not content with that they also set a record for travelling upwind 2.01 times faster.
Bidding is currently at $1,575 (£1,030), a bargain when you consider it cost $20,000 (£13,080) to develop.
