-> The problem with using a crank at the bottom to convert back to rotary is
-> what happens if the wind dies down and the windmill stops with the crank at
-> either TDC or BDC. When it tried to move again it would either be pulling
-> straight up or pushing straight down and with no sideways force to get the
-> bottom crank turning again it would try to hold the windmill blades still
-> which could break something if the wind got strong enough.

Put a weight on the bottom crank so the system won't stop at TDC or
BDC.
