I've never understood why there is not a prop shaft the length of
those towers and then any old (heavy) generator at ground/sea level.


Think about it for a while.
Hints;a 160 ft long shaft,torquing in the wind,and needing bearing support.
then there's the mass of the shaft that has to be started and stopped with
shifts in wind velocity. Cost of the shaft,too. I'm sure there's more.
