This Wind-Powered Cart Is Actually Faster Than The Wind

This wind-powered cart breaks the rules of science because it's actually faster than the wind itself. When the wind was only blowing at 32km.h, the cart managed to hit speeds of 80km/h. Here's how it works.

Of course, the cart, called DWFTTW, is ultra-lightweight and super aerodynamic. That's a given. But the science (or magic) lies in how its propeller and wheels interact: the 5m propeller is driven by the cart's wheels.

It's sort of confusing to think that the wheels turn the propeller, since the propeller also turns the wheels, but thanks to a very capable of transmission and the wind being an external power source, it manages to go faster than the wind.

Maybe these guys can cook up a solar panel that can give more power than the sun next. [Faster Than The Wind via Wired]
