alt Hacker NewsThe biggest problem is it's spin rate: a Venus day is 116 days Earth days or so.
Being completely tidally locked would be better because near the transition zones the permanent sun would make solar power and plants quite productive.
But an ecosystem where the planet spends most of the year in darkness or dim light?
Basically it's relatively easy to redirect comets to provide gas and liquids for the surface of Mars: that's technically demonstrated technology now.
There's almost no plausible way we could add momentum to Venus to give it a more reasonable day night cycle (I have seen some suggestion that shearing asteroids into it might be possible, but just the magnitude of momentum you're trying to add is staggering).

If you're floating you don't have to track the ground.
The atmosphere has a perfectly reasonable 110 hour day/night cycle.

How would that work? Averaged over the planet, you get half the year in darkness and half the year in light. There's no other option.
We have that same ecosystem on Earth.
If I remember correctly, the habitable-ish cloud layers have super-fast winds that circle the planet once every 4 days or so. [0]
