Something that disappoints me about the comments to this story is no mention of engineering optimization. The marketing shows it outperforms at very high power level at very high speed. Then the message veers off into ultra low speed modest power level applications like bulk cargo hauling, and fairly generic greenwashing, we can save the earth with this one nifty techno trick. A better application would seem to be unlimited-class racing boat props or military-industrial complex torpedo propellers. They have infinite money, which makes the situation interesting. There's an old joke that an engineer and an economist see a nickel on the ground and the economist tells the engineer not to bother trying to pick it up because the efficient marketplace theory proves there can't be nickels laying around ready to pick up, therefore it can't be there, must be an illusion. However, in the context of people with large amounts of money willing to pay anything for higher performance, it seems odd that a mere propeller shape could exist that nobody is already paying for, that nobody has been paying for over the last century. My theory would be there's something about this prop that nobody is talking about. Most boats most of the time are not full throttle. WRT durability I wonder what its cavitation behavior is like.
