Directly Downwind Faster than the Wind (improved audio)

Actually, you just proved it, or well, the other guy did. He just invented a way to harness wind in such a way that it's possible to make the device go faster than wind. All it requires is a vehicle with low aerodynamics such as... all the ones used, and that design where the wheels power the fan.
A hint. Try to create a device that uses gears to make the fan spin faster, and use a fan that's better designed to shoot a 'jet' of air instead of just... well, fanning air backwards. It'll go, fast!

well, this is better sitting around hang gliding and nothing better to do in the mountains

Great compilation gentlemen. Having tried to get this simple concept through thick heads I appreciate this contribution.
I made a very simple vehicle that I have posted as DDWFTTW_Analogy that shows how a vehicle can move ahead of the media being used to push it along.
It is nothing earth shattering but it shows the importance of gearing.
JB - None of these machines have been particularly optimised. If you want to do some proper design I can help. One little tool that is very useful is a prop design program that can be run from explorer. Google JavaProp and then run the Applet there.

Thanks Rick.
If we were trying to find the top speed of one of these then optimizing would be critical, as it is we only wished to prove that a speed greater than TWS was possible.
Thanks for the great geared cart example. Very nice.
