Japanese telecom NTT, suggests high-altitude solar-powered drones could be 5G base stations in Africa. With coverage of 200 sq km per drone, approx 150,000 of them could blanket the continent with 5G (interestingengineering.com)

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.
