I'm thinking elaborate gimmick   or at least a cavitation mess.

I am not sure I believe their claims regarding fuel savings. That being said the cost of their propellers would by a lot of fuel. Way out of my price range.

Boat test has a youtube showing the difference between a regular prop and a toroidal prop. Big difference in efficiency.

But at $5k per prop.... I'll have to pass...
