Idea for Bilge Pump requiring no power

[Tom G.]

FYI - See below for idea that might be helpful in your inventing. Good
Luck!

There are powered bilge pumps for boats but do not seem to be a passive
bilge pump that requires no external power - only forward motion of the
boat. Think of a long hose or tube with one end on the bottom of the boat
and the other end is hanging outside the boat. As the boat moves through
the water, the moving water over the end of the tube would suck the water
from the bottom out of the boat. A one-way valve would only allow the water
to be sucked out and not into the boat. This concept is similar to smoke
being sucked out of an open car window, when the car is moving.

Possible Start Building Blocks -
* Existing concepts for carburetor venturi, airplane wing lift, vehicle
air flow analysis, siphons, snorkels, vacuum cleaners, etc.
* USPTO Class/Subclasses for "How-To" ideas - 114/183A, 114/183R, 114/197
