This topic came up a few years ago. I think I may know a way to speed
it up.
The biggest problem we face is heat. How do we get rid of it?
Build self replicating balloons with on board solar powered dry ice
machine machines. Build enough to completely obliterate the sky. Once
this is done, the balloons start manufacturing dry ice chunks and
shoots them deep into the Venusian crust. Once Venus is cooled, the
balloons could convert the excess CO2 to lime and bury it in the
crust. They could also break down the sulfuric acid and use the
hydrogen in it to make water.
Could this work? |

How do you suggest that we make self-replicating balloons? Balloons
are typically a rubbery, filmy substance, so I suspect that it might
not be too hard to manufacture on the spot, especially if the life of
each balloon doesn't have to be too long (circulate some hydrogen,
don't worry too much about hydrogen loss, etc.). Thoughts?

My first response was 'Parasol satellite', an started to imagine how
one could be made, -but then I wondered- what is the main source of
that heat? Solar or Planetary?

The one thing I wonder is that in the making of dry-ice the machines
will warm up due to the work involved.
If they are in the planets atmosphere this will add to the air.
Should you leave a fridge on and open in a closed room it will warm up
the room, as cooling is gained at the cost of making a larger amount
of heat than would have happened naturally.
So Id say that it would eventually do the opposite of your
intentions.
Sorry.
But maybe a trick with colour changing balloons could.
Have them black on the nightside and silver on the day.
Can anyone spot a flaw with this?

Okay... What if these balloons were operating at an extremely high
altitude where the air temperature was well below zero?
I just had another thought. What if we turned the CO2 into diamonds
and dropped them on the surface? Venus isn't hot enough to burn
diamonds, so they should do fine. Would that be enough to start a
cooling trend? |

With assemblers, using solar energy and carbon extracted from the
abundant CO2. |

If you have those, why would you need balloons to do your
terraforming? Why would you bother with crude disposal methods for
the CO2? (A lot of this is like using your brand new immensely high
tensile strength materials to make better bridles for horses...)
In any case, if you just want to cool the planet in initial stages,
shading it from space seems much more efficient, and I'm not sure why
you would bother with specifying nanotubes...
