So, I read on the net the other day that one method of delivering water while terraforming Venus (this is assuming the problems of day length and sun exposure are sorted out) is to bombard the planet with hydrogen which reacts with the co2 atmosphere to produce water and graphite.

The article I read this on suggested using hydrogen from Jupiter, but in my project Jupiter has already been claimed by another state looking to terraform Ganymede, so the Venus terraformers use a Bussard ramjet field to “harvest” hydrogen from the atmosphere of the sun, where it is then delivered to Venus. The problem of getting the ramjet close enough to the sun is, I figured, not an issue since it can be placed at a distance and the electromagnetic field is extended for the rest of the way.

Is this plausible? I can’t find a problem with it myself, but I want to be sure.
