Could an airship or similar (maybe over an ocean) capture atmospheric helium?
There is a shortage of Helium (and 3He and 4He for fusion), which the sun makes out of Hydrogen with heat and radiation from fusion and fission.

Our helium supplies come from natural gas wells. In some areas the natural gas contains enough helium to be worth separating and storing.
