Scientists in China are constructing a large-scale, space-based solar power station, which they claim could generate more energy annually than all the oil on Earth combined. The proposed structure will be over half a mile long, and located approximately 22,236 miles above Earth, transmitting power back to the planet via microwaves.
This endeavor aims to address limitations of terrestrial solar power infrastructure, including disruptions caused by cloud cover and atmospheric absorption. Solar energy in space is reportedly 10 times more intense than at Earth’s surface, offering significant potential for continuous energy collection.
Historically, large-scale, space-based solar power systems have faced challenges due to the need for multiple rocket launches. To overcome this, Chinese scientists are developing reusable heavy-lift rockets, capable of carrying at least 150 tons into orbit. These rockets are intended to reduce the number of launches required to assemble the solar array.
The project’s lead scientist has compared the endeavor to the Three Gorges Dam, a landmark hydropower project in central China. The dam, the world’s largest hydroelectric facility, generates enough energy to power nearly 9.5 million homes annually.
