ToughSF links Jakub Grygier on the stellar lifting concept. Get something into a low orbit around the Sun as to extract its hydrogen and helium.
For helium, starlifting involves lasers and/or magnets to speed up stellar fusion at local points on the Sun's surface - basically inducing flares. The helium would be condensed. Into liquid helium. Which is a superfluid. Er.
I think gathering hydrogen into hydrates or even soot would be better. They stay bound with their molecules at high temperatures. Anyway the cost of hydrogen storage and transport seems like it's getting lower.
Where do we transport this stuff...? I'm thinking any of our hydrogen-poor planets, asteroids, and of course our own Moon. Probably not Venus; the acid has sufficient hydrogen at cloud-level, and statites can gather hydrogen in orbit.
Overall I rate this whole scheme as "silly".
