so obviously they will have to deal with rain, fog, flies, mosquitoes and bird crap in order to be usable. Weather forecasting is good but not that good.
that your observations are incorrect, which leaves the plane facing a considerable challenge.

t viable. Maybe if you get one big enough to be useful everybody around wil l be brown.
d drones. I expect this would be right up their alley.
era. Being ultralight it's not going to be picked up on radar, but would ha ve to transmit to be useful. A very slow moving fragile transmitting target ... probably would work over friendly civilian areas, not so sure about any where else. Which might make it more interest to police, if it ever gets ro bust enough to cope with wind. No way will it fly high, it's real windy up there.
bout the wind itself unless it is tethered or is taking off/landing.
At the risk of stating the obvious now, when there's wind there's turbulenc e, so wind is an issue. And yes, the plane will take off & land routinely, if it ever ends up in use.

This is the biggest problem they will need to solve. With an external PSU that's nothing new, already done and flown:

Well, book a flight with a decent airline...
Interesting, clean frozen water between the the electrodes, conductivity? Or acid rain:-) better conductivity?
FAA experimental ? ;-)
Be careful OK?

Not necessarily a self-contradictory statement. Flying an atomic PSU, of betavoltaic type maybe? ;-)

So which space shuttle was it that was destroyed by storms? I can't recall.
Yes, thank you for your valued input.

So, what happened to Wilbur? :-)

They could just connect roughly the number of 16850 cells in a Tesla- maybe double the number- in series and get 40kV directly from 3.7V cells. Balancing the charge might be .. interesting.

easy - once fully charged that group of cells arcs over :) Now put spark gaps from cell 1 to 991, 2 to 992, 3 to 993 etc all the way through the pack. Not explaining it well am I. If you had 20 cells and a SG for every 10 you'd fit spark gaps to the 20 cells: cell 1 to 11, 2 to 12, 3 to 13 etc. Too tired to work out if that'd really work.

Clearly too tired to think about what he's proposing either.
Spark gaps are arcing devices, so once the spark has set up the arc, the voltage drop across the spark drops to something like 20V and all the cells get drained very rapidly.
This isn't a charge balancing scheme, it's a battery discharging scheme.
