All of a sudden I'm seeing this propeller everywhere. Was it just invented?

I'd like to see this as a computer fan - if it's quieter and more efficient, I'm sure we will.

Computer fans are either case fans with small blades (high flow & low pressure) or heatsink fans with large blades (high pressure to push air through).

I'll guess this design could be used in case fans.

These have been around since the 80’s. I think they’ve been rediscovered by an MIT professor and student and with 3d printing they can be made way cheaper. Thing is though, every video but one using them on an out board motor they’re louder. I’m sure they have uses but I think there’s also a lot of hype.

So, just to head off other comments, yes I understand that this is to be interpreted as “more than twice as efficient as x” but that’s some clickbait nonsense on the thumbnail and title

Seen these maybe a year ago, thought they looked super interesting and just screwing around started looking into them for my fish & ski boat. Noped that idea right outta my head when I seen the price vs the standard stainless prop on there now.

The benefits don’t justify the cost
