An engineer did the rundown on a list I was on.
It basically amounted to having to use about six times the normal amount of
wood to get the draft necessary to turn the blades.

It seems that most people who start with this idea end up with a simple
weighted jack or clock jack due to size and weight restrictions.

I am NOT saying don't try.   I'd love to see one of these in action. Later
today I'll see if I can find the engineers notes.
