Expert predicts China's gigawatt-level space power station construction.

China is planning to build a gigawatt-level space-based power station, according to the Chinese Society of Astronautics space solar power commission. The project will possess power capability of 1 billion watts and will be operational for commercial use. The future space power station will likely have a scale of more than 10,000 tons, and to reach that goal, China needs to grasp the capability of wireless power transmission technology, which is a must and the greatest challenge in the process. The US, UK, the European Space Agency, Japan, and South Korea are also exploring the field.
