# Terraforming Venus with the Bosch reaction, using hydrogen from Jupiter [closed]

OK, so chemistry and physics are not my strong suit, so this idea is just cobbled together from stuff I've heard can be done. But I'd be curious if it is at all plausible, and what the most likely pitfalls would be.

## Procedure:

1. Set up a hydrogen mining platform on Jupiter.
2. Harvest iron from as near as possible (not sure if there is enough iron dust around Jupiter, or if it would have to come from further afield. I suppose there is no practical way to get iron and nickel from the core with the crazy pressures down there).
3. Get the iron/iron ore to the $$\require{mhchem}\ce{H2}$$ mining platform.
4. Fabricate $$\ce{H2}$$ filled iron spheres.
5. Use a rail gun to shoot them out of Jupiter's gravity, on a trajectory to intersect with Venus.

## Expected results:

1. The iron spheres would burn up or react with $$\ce{H2SO4}$$ in the Venusian atmosphere.
2. The temperature will be high enough for the $$\ce{H2}$$ and $$\ce{CO2}$$ to react, and the disintegrating iron from the sphere would catalyze a Bosch reaction, producing $$\ce{H2O}$$ and graphite.

## Reasons why this might be a good idea:

1. Scalable. Experimental $$\ce{H2 - Fe}$$ spheres could be made near Earth, shot at Venus, and the effect measured, so the reaction could be tested and optimized.
2. Swarm based. The fate of any individual sphere matters little, making the system more resilient to space debris.
3. The magnetic properties of the spheres could be harnessed to minimize the cost of propelling the spheres to Venus.
4. Could probably be fully automated.

## Reasons why this might be a bad idea.

1. The magnetic launch of the spheres might not practical. This plan depends on it being feasible and cost effective to hurl the spheres at Venus such that they do not need propulsion systems of their own. I imagine a hose $$\ce{H_2 - Fe}$$ bubbles squirting Venus from across the Solar System, but it is late at night and my imagination may be getting the better of me.
2. It might be too hard to target the spheres, even if they could be shot across the Solar System at low cost. Too many might miss. What would happen if some rained on Earth?
3. The $$\ce{Fe}$$ could be eaten up by the $$\ce{H2SO4}$$ in the upper atmosphere of Venus, preventing it from acting as a catalyst.

3. What would be the optimal ratio of $$\ce{H2}$$ pressure inside to thickness of the iron sphere?
4. Would an $$\ce{Fe}$$ sphere filled with $$\ce{H2}$$ falling into the Venusian atmosphere as a meteor be expected to produce a Bosch reaction?
