China is looking for the greatest efficiency to generate clean energy, and this project looks like science fiction. It is a solar station that will not be subjected to atmospheric interference since it will be located thirty-six thousand kilometers from Earth and will even be used to explore other planets.

China has announced a project to build a solar photovoltaic station that will be 36,000 kilometers from Earth. The idea is that it can capture the sun’s rays without interference from the atmosphere, generating energy twenty-four hours a day.

Since it has no interference from the atmosphere, it is much more efficient, it improves up to six times more energy capture compared to a conventional photovoltaic system located on the ground.

Solar energy is would send to earth via microwave or laser beam, once on land, it would be converted into electricity for consumption on the conventional power grid.

How will a solar power plant be built in the stratosphere?

In Chongqing City, construction of an experimental space power plant has started. The first step is to design and implement small solar space power plants, between 2021 and 2025. Once ready, they will be sent into space.

Based on the test results, a large-scale solar power plant would be designed; should weigh approx 1000 tons, built by robots and 3D printing technology. It should be ready in 2030.

The solar station requires the construction of a base of operations on land. It will be ready in about two years. Once operational, they will be built globes equipped with solar panels to be used for checking microwave transmission technology.

Four to six balloons are expected to be launched from the test base to link them together. Being interconnected, a network is configured at an altitude of approximately 1000 meters.

Some aspects require further research and development. The long-term impact of microwave radiation from a special station on the atmosphere.

China’s intention is to offer another solution for the decarbonization of its economy. In addition, by having a power plant in space, they will have more facilities for the exploring other planets.
