It might be fun, but I really can't take up that project now. I would think that a company like RotorSwing could easily test the approach. There is one other refinement to throw out. If the cylinder is a permanent magnet, in salt water there may be a little bit more water entrained, improving...

Think of a flat plate of steel on a slippery surface. If you lift an edge of the plate, the plate slides forward. Just as the development of a bow wave impedes forward motion, and a stern wave boosts forward motion, the lift ends up as propulsion.

Has anyone investigated the use of a Magnus rotor placed horizontally in the water? When heading into a current, if a Magnus rotor is affixed to the stern, it will create a lift at the stern which will end up giving forward propulsion. The Magnus effect is 830 times stronger in water than air...
