How can a turbine run at MPH?

wind speed, presumably

One of my dislike about these contraptions is the amount of gubbins to
run before anything useful comes out.

None produce useful amounts of energy without decent wind...

This one is pretty well a wind-driven electric motor:

A motor converts energy into motion of some sort. Have you thought this
one through?
