Ah , but lift a BOAT PROPELLER up out of the water and see how fast the boat will go , by forcing the air backwards.

its basicaly a fan in water.

the boat did move as rapidly or more as a standard motorised boat would , momentarily.

and then as soon as the water moved under the boat , the boat lifted , and the rear of the boats bottom could be seen as in the below image.

and the pipe could be seen above water.

causing its momentum to decreased.



the mythbusters dishonestly busted this as the compressed air from the pipe is supposed to react against the water.

notice in the above image the boat propeller is still under the water , you cant even see it.

how many BOATS have you seen with propellers placed above the BOTTOM of the boat?

if the above moving boat were the boat that mythbusters used
the pipe that released the compressed air would be located at a height apx 2 inches above the water level seen at the rear of the boat in the above image.

But its a energy thing , they probably got a few bucks for this one.
