Power plant for space immigrants

Some countries are brewing a plan to solve the earth's energy crisis: building space power plants. The space power station consists of two parts: the space part-solar power generation satellite, and the ground part-receiving power station. Solar power generation satellites are launched into space orbit by rockets. In space, power generation satellites convert solar energy into electric energy, which is transmitted to ground receiving power stations through microwaves, and then supplies power to users.

The sun is a huge energy pool, and solar radiation releases huge energy. Because the earth has a "thick coat", most of the solar energy emitted to the earth is absorbed. Therefore, only by launching the power generation satellite into the outer space orbit with thin air can the solar energy be fully converted into electric energy.

1992, Japan Cosmological Research Institute manufactured a small solar power generation satellite with a triangular prism shape, designed output power of 1000 kW and satellite orbital height of 1000 km. The power generation satellite is equipped with a transmission antenna and a plate-shaped solar cell array made of amorphous silicon, and it orbits the earth once every two hours. When the satellite runs close to the ground receiving antenna, it immediately emits microwaves with a frequency of 2450 MHz and integrates the microwaves into the ground receiving antenna.

According to the Defense Advanced Technology Research Projects Agency of the US Department of Defense, the United States intends to launch 5 ~ 16 100 kW small nuclear power plants into space around 2000, and further develop large nuclear power plants to provide energy for space bases.
