Funneling Protium to Venus to be used to make light water. My idea is a sort of lense with a focal point within the Venusian atmosphere. If my thinking is right it should produce Methane and Water when reacting with the C02. If it is collectible only a few gallons a day would be needed to cover the needs of a cloud settlement as it would be recycled vigorously.
Well you're in luck! Venus has no magnetosphere to deflect the solar wind, only an induced ionopause. The solar wind is full of H+ ions, so I think that what you're trying to do is actually already happening to a degree (physics pun!). My guess is that the H+ recombines with solar wind electrons before it has enough interaction with the CO2 to tear it apart. You're really keen on that Venus colony, huh? Myself, I don't find the idea too feasible, but I hope I'm wrong.
They blow in then out with a net loss.
I just want a bunch of em in the same place. Terraforming is a fools errand I just want to see a permanent cloud colony that grows its own food and does science. [edit added phrase "and does science" there at the end]
