| 摘要 |
The present invention is realized by apparatus and methods for placing a large rigid buoyant platform in the low stratosphere of earth's atmosphere at an altitude of about 20km, above clouds, moisture, dust, and wind. The platform can serve several uses, either individually or in any combination. These uses include uninterrupted radio and light communications, radar and optical observation including very powerful radars and solar power electricity generation. Long, strong and light tethers connect the buoyant structure to the ground which hold it in position against wind forces. The electricity output from a photovoltaic array is used to power platform uses and can also be coupled to high voltage transmission lines which connect from the platform to the earth's surface. The electricity can be transmitted through the high voltage transmission lines to the earth's surface during daylight hours. |
