Actually, it looks kinda like a design for a Biefeld-Brown field generator. At least 2 charged electric plates, one larger than the other, that rotate. This one would be a stack of them, slightly offset with the angles representing a rotation. It creates a propulsion effect that has been explained away as being a kind of ion drive. But in the UFO community is believed to be an advanced propulsion system used in UFOs that creates a gravity distortion. Word is that Brown's research and working models were confiscated by the military and nothing more was heard about it.
Or it could be a kind of clutch plate for manual transmissions and aliens are making fun of people who can only drive an automatic.
