That fog would absorb heat radiated by the sun and then pass on the
heat to the surroundings. You would need something to reflect as much
radiation as possible, rather than absorb it.

I'm imagining a large gas or dust cloud assembled and held
electrostatically in space above Venus to block the sunlight. You'd
maybe have a large grid-array of cables generating electrostatic
fields to hold the dust or ionized gas in place.

Nah, I don't see that enough miracle nano-stuff could be made to
achieve this. I'd say that people would have to live underground on
the Moon.
