Everyone does harp on about domestic infra and, to a certain extent, you're right. But at the end of the day, the entire country is already wired for and produces natively electricity. So yes, charging points are required for out and about. But if you're a car park owner or a service station owner and the money is right, market forces will make it happen. There's enough chickens out and about already to rapidly increase the number of eggs, so it's only a matter of time.
Military wise though, the high altitude pseudo satellite application is where it's at I'd say. Definitely a market there, both disaster relieve and permissive air environment conflicts.
