Thas so cool I want one for commuting down the Thames LOL. But how does it work does that pipe just trail in the water and the motor is attached to his back and the pipe just sucks up and uses the water around it or is it attached to summit else.
They did something very similar on 'Bang Goes the Theory' and the hose will be a water feed as it uses an incredible amount of water and power to get any lift.This explains all http://www.youtube.com/watch?v=ZFjih5bFfK8
The pipe is attached to pump that is towed behind it. Looks like a small boat. Due to teh weight of the boat/pump that it drags behind it stops you lifting any higher than 35 feet.
