[Fwd: Re: Rougtero Water Screw]

[Joe Gregorovich <delmar@ameritech.net>]

Dusk has a ~250 met an hour jet boat that works on the dervish
principle, can't make 'em like that again, so I keep it in hiding like
his submarine.

Rick, Difuge made her own bag, and Orion's character cast the adamant
spell.

To fly you have to move a lot of air (very compressible stuff) at a
pretty good clip. To pump water (to either move the water or, in the
case of screw powered boats and subs, move the pump) is much easier
since water is not compressible. Dervish powered screws are where its
at :)

Using the screw pump you can change the tubing diameters to get
pressure variences to force better speed than just moving water.

Using an inverted screw could be even more successful...
