I Turned MIT Award Winning Toroidal Propeller Into A PC Fan
| Fan Showdown S5 Special - YouTube

<https://www.youtube.com/watch?v=4ImeOKgD_Dw>

"MIT has just been awarded an R&D 100 award for the work they did on
toroidal propellers. MIT set out to create a drone propeller with
similar performance to standard propellers but while being much quieter.
Well spoiler alert they nailed it, demonstrating a Toroidal propeller
on a consumer drone that seemed to check all the boxes."
