@mtyka fancy! The article mentions aircraft and vessels, but could that new shape also be beneficial for wind turbines? Smaller, more efficient and quieter - that's also a topic for wind power plants. No expert re that, though.

@xela That's a very cool question and I got curious too. As it has been a year since the original article and the toroidal propeller has received some attention during the year, I was hoping someone would have looked into the reverse case, and they have!
A couple of proper papers out there, but I settled for this chatty fellow who just took a propeller, put it in some wind and wrote down the numbers.
It doesn't actually fare that well, and the comments speculate that this is because the toroidal propeller primarily addresses cavitation, which occurs when it's (1) in a liquid (2) propelling.
I would still be interested to know if this or another wind turbine design could reduce noise compared to current designs!

This article makes the fair counterpoint that just taking a thing and throwing it into a random test doesn't make for very informative data.

A propeller or turbine will be optimized for specific circumstances and to say if toroidal design is better in some way to classic design, you'd have to build an optimized model of each for some specific scenario of whether it's pushing or being pushed, what the medium is, what the load is and what the speed is.
So maybe I'll have to read those papers after all. 😊
