nice

I see a lot of potential in these systems:
- The large diameter of the motor will produce a lot of torque.
- Potential for max efficiency with the direct drive (no gearing or gearbox).
- Minimal profile in water, the benefit of ducting (efficiency and build-in rudder function).
- The rim-mounting of the blades (no center hub) should make them much less sensitive to damage.
With somewhat flexible blades (less pressure on the blades in the center),
they could survive chewing on fishing nets, logs, big fish, terrorist divers and pirates etc.

The big question now is longevity, effectiveness, availability, and prize.

Any risk of a galvanic corrosion problem on metal ships with the Carbon/plastic?
