why tether? why not let the balloon charge a battery, and have drones carry the battery back to earth when full, and vice versa...

- Jedd 11y agoGood question. The winds up there are really strong. Tethering also lets you wind the appliance back to the ground even when (especially when) it's faulty. Tethering also lets you obtain power throughout the 12+ hours of power generation per day.
- djKianoosh 11y agoMaybe the balloons could be autonomous as well, rising/falling depending on conditions, and also falling to an acceptable elevation for the drones to reach them efficiently :)
- shkkmo 11y agoBatteries are heavy, lifting them with aircraft is significantly inefficient.
