Your Questions About Wind Turbine Manufacturers

Heard of new wind turbine with no blades?

I heard from my biology professor about a new type of wind turbine that was designed in Michigan that doesn’t have any blades, so it doesn’t effect birds & bats. Instead it has this circle thing at the top that twirls around.

Has anybody heard of it? I’m trying to find an article on it so I can add it to my wind turbine paper but I can’t find a thing.
