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.
