Solar powered permanent data relay installation ~1km from me:

Well, that is even better  :-+ , but for the sake of argument, say its not for permanent, still a balloon is much-much cheaper and reliable for hanging those electronics way above there, right ?

The HW doesn't weigh much, say 40kg tops but the batteries and solar panels are an entirely different matter.
This is a point to point backhaul link of some 400MB/s capability consuming 25-30W.
Want some decent data throughput only cell towers connected to fiber can offer that and with your proposed balloon how on earth do you keep your HW orientated correctly ?  :-//

At least a GPS capable drone has a chance of keeping HW pointing in the right direction

I thought Google use this balloon tech ?  :-//
Cyberdragon:
You can still have horizontal propellers on a ballon for orientation (basically like a powered hot air ballon but on all sides) that would be a lot less power than using them for lift and stability.
shakalnokturn:
Drones would have to spend a lot of energy just to keep aloft a big part of which because of the on-board backup battery.
Balloons obviously need less energy to stay up but could need quite a lot more energy than drones for position compensation when there's wind.
How about inflatable pylons? They would still need some active compensation to keep the long distance radio link aligned.
james_s:
A balloon doesn't have to be expensive.

It is idiotic to waste precious helium in unmanned balloons. Hydrogen is cheap, widely available, renewable and offers greater lifting capacity than helium. The flammability limits its use in manned vehicles but the small risk of a mini-Hindenberg disaster is not an issue for a payload of commodity electronics.
