A simple water pumpgreenspun.com : LUSENET : Junkyard Wars : One Thread |
No motors for this one, all human power.Archimedes screw vs a centrifugal vs a piston style pump or anything else the teams can come up with.
First team to pump a certain amount of water wins.

the only problem with an archimedes screw is that its only a low level lift, no pressure pump..it could almost be considered a water elevator!

How about a water ram. A device that uses the energy of falling water to pump water.
