How to make Venus habitable
« on: May 06, 2017, 10:58:06 am »



Is it possible to synchronize a dispersion lens in an orbit closer to the sun, with the orbit of Venus, like in the illustration?

With gigantic engines, yes.

Get closer to Venus, build a large solar panel conglomeration there, and you'll have energy for many projects too, and much easier to keep in relative station too. But would still be horribly expensive.
Or build several that circle Venus, so that always one or two cast their shadows on Venus. More energy, less stationkeeping, likel overal more efficient.
Cheapest solution is building a large shadowing sail that you keep over Venus.

 but the atmosphere itself is toxic too. Not just the temperature.
You'd need some thousands of years of bioforming the planet before seeded bacteria, algae, and later plants would make ot breathable.

This actually sounds like a good idea. We could build a solar panel conglomeration there to block sunlight from reaching Venus, and use it to power a laser that is used to increase the temperature on Mars. Or put a huge mirror with a lens near Venus, which is used to redirect sunlight to Mars.

Nevertheless, getting a colder Venus and a warmer Mars from the same project sounds like a good idea.

but the atmosphere itself is toxic too. Not just the temperature.

Some types of bacteria and archaea can live in highly toxic environments. My avatar, the tardigrade ( https://en.wikipedia.org/wiki/Tardigrade ), can also survive in harsh environments.

Btw, the clouds of sulfuric acid will condense if you make Venus colder. The boiling point of sulfuric acid is 337 C.

We did. You did. Yes we can. No.

You could put Pluto (other out-system destination)'s light collection thing (mirror or PV array with transmitter) around Venus's L1 point. That would help both of them.

Also, Venus has a ~1 atm, room temperature band in its atmosphere. Sitll a bit on the acidic side.
