I wonder what level of hydrogen production is needed to set up a colony on Venus (airships are very necessary on Venus to stay up and away from the heat, and hydrogen seems like a good buoyancy gas for Venusian airships).
A colony on the surface of Venus would have other (more pressing) limiting factors than hydrogen production.
Among them, cooling - as far as we know, it’s almost hot enough to melt aluminum on the surface, and the pressure is 93 Earth atmospheres, giving the highly corrosive Venusian atmosphere excellent thermal conductivity to quickly cook any human despite passive and active protection.
A colony could perhaps exist floating in the clouds, but Mars and the asteroids are generally considered better candidates for space colonization.
Thus, I think the foremost application of this technology will be on Earth. :)
None. There is a practical temperate and pressure high in the atmosphere there, but it’s an incredibly difficult place for a person. Using electricity to generate hydrogen from water doesn’t really make it meaningfully easier
None, earths air would be a lifting gas in Venus atmosphere, so that would be the obvious choice.
