What you have to notice is that the turbine is not moving the wheels, but the wheels are moving the turbine, this means that the turbine is blowing in the direction that the wind is coming from. The wind pushes the cart forward, this sets the wheels in motion, which in turn sets the turbine in motion, which generates extra trust. Really cool and at first contra-intuitive.
