Overview of the stratospheric communications satellite. Assuming it is 15km above the ground, a 20m diameter parabolic antenna will generate 70kW of power. The battery weight required for nighttime use is 1.8 tons. The water required for power generation does not decrease because it is circulated. In principle, it moves at the mercy of the wind, but it sometimes moves sideways, so it uses a steam jet at this time, which requires water. It also has a small propeller, but this is only used for fine adjustments when landing on cloudy days. At this height, the buoyancy of one hydrogen balloon with a diameter of 10m and a length of 100m is 1.4 tons, so four balloons would be 5.6 tons. This should be enough. The buoyancy decreases significantly as the altitude increases, so it was lowered. Hydrogen loss due to seepage is constantly replenished through electrolysis, and some is released during descent. Water can be easily replenished by descending to the ground, but it can also be collected in the air. Hundreds of these will be launched all over the Earth and managed by AI like a drone.
