I imagine power generated is proportional to current velocity and diameter 
of the turbine. I can't imagine anchoring in any more than a 4 knot current, 
nor dealing with or throwing overboard a turbine any more than one or two 
feet in diameter.

I wonder what kind of electrical power that would generate?
