Fuller
The "Fuller" wind turbine is a fully enclosed wind turbine which uses boundary layers instead of blades. Much like a Tesla turbine.
Imagine a stack of CDs on a central shaft with a small air gap in between, the surface tension of moving air as it passes through the small gaps creates friction and using this energy causes the CDs to rotate around the shaft. The Fuller has addition vanes to help direct the air for improved performance, hence it isn't totally bladeless, as has been suggested.

“You’re in a hopped-up, show-off stage. Get off it! Don’t be Moses leading your lunatics to the Pulitzer Prize!”
—Samuel Fuller (b. 1911)
“Fame sometimes hath created something out of nothing. She hath made whole countries more than nature ever did, especially near the poles, and then hath peopled them likewise with inhabitants of her own invention, pigmies, giants, and amazons: yea, fame is sometimes like unto a mushroom, which Pliny recounts to be the greatest miracle in nature, because growing and having no root, as fame no ground of her reports.”
—Thomas Fuller (1608–1661)
“With foxes we must play the fox.”
—Thomas Fuller (1654–1734)
