Saves me saying it.

3/8th sphere produces lift. You have to strap them down so they don't blow away. 5/8th sphere has more frontal area but proportionately less lift so IDK.

The zenith of the dome has the fastest local air. So, a vertical axis windmill there. Follow Julian Edgar's article on Autospeed on vibration damping for the mount.

Fan above and generator below the mounting point in counterbalance.
