That's what first came to my mind. Water from air to hydrogen from water. Would need to do r&d tho to see if it's possible.
Pretty sure the only R&D you need to do is thermodynamics 101.
Is the energy from the sun that could be harvested from a blimp sized footprint enough to convert enough hydrogen to account for the leaks in a blimp and to power propellers to keep it in one spot.
I don't know those numbers.
