With the acceleration of the green energy transition, solar farms have become a familiar sight across the nation and around the world. But China is taking solar energy to a whole new level. The nation has announced plans to put a solar power plant into orbit by 2050, a feat that would make it the first nation to harness solar energy in space and shine it to Earth.

As the sun always shines in outer space, in space solar power is regarded as a uniquely reliable source of renewable energy.

"You do not have to deal with the day and night cycle and you do not have to deal with clouds or seasons. You have eight to nine times more power available," says Ali Hajimiri, a professor of electrical engineering at the California Institute of Technology and Director of the Space Solar Power Project of the University.

Of course, the development of hardware that is available for detecting and transmitting solar energy and launching the system into space is difficult and costly, but China is on the rise: The nation is building a test facility in the southwestern city of Chongqing to determine the best way to transfer solar energy from orbit to the ground, the China Daily reported.

An old idea picked up again

The idea of ​​space-based solar energy Being a reliable source of renewable energy is not new, it started in the 1

970s Years, however, the research largely remained, because the technological requirements were considered too complex. However, with the advances in wireless transmission and the improvements in the design and efficiency of photovoltaic cells, this seems to be changing.

"We're seeing a bit of resurgence now, and that's probably because this is possible thanks to new technologies," said John Mankins, a physicist who led NASA's efforts in this area in the 1990s before the space agency

Population growth may be another reason for Mankin's renewed interest in space-based solar power, with the world's population expected to grow to 9 billion by 2050, experts might say that this could become an important path to cover the world's energy needs – especially in Japan, Northern Europe and other parts of the world that are not particularly sunny.
