Capability of producing He3 in gas giants? (article below)

According to the article еhe lunar regolith contains up to 15.1 parts per billion He3, while Uranus' atmosphere has 15,000 parts per billion He3. It is proposed to process  atmospheric gases in a flying factory, obtaining  Helium-3 from them. The cargoes will be lifted into space by a direct-flow shuttle, the construction of which I don't really understand.

I know that flying colonies are not in priority until maybe 1.0 release, but it is very interesting and extraordinary way to use gas giants, as Jool and others in different star systems
