China Successfully Tests Solar Energy Collection Tower

True, while it is capable of transmitting only within 55 meters - instead of the necessary 36,000.
Chinese scientists successfully tested one of the key systems of the tower for collecting solar energy in space with its subsequent transmission to Earth. It is being built on the basis of Xi'an University of Electronic Science and Technology.
This is the world's first unified system covering the entire spectrum of functions from tracking the Sun and concentration of light before converting it into electricity, transmission in microwave form and reception on a separate channel.
The construction of the 75-meter installation began in 2018. She will remain on Earth and will receive energy with a plate of rectenna and transform it for further use. The second part of the installation will consist of several dishes that receive sunlight, concentrate it and transmit it to the Earth, to the tower.
According to a press release from Xi'an University, the installation was tested by a group of 9 independent experts who confirmed the correct operation of the wireless system. microwave power transmission at a distance of 55 m. It is noted that the development is going faster than planned: it was originally assumed that these tests would be carried out only in 2025 year.
However, the project is still far from complete: increasing the power transmission distance from 55 to 36,000 meters is a task that scientists say will take generations to complete. It will be a long time before such installations become more efficient than installing conventional solar panels on the Earth's surface.
The Chinese authorities expect to launch the first 1 MW power plant into orbit by 2030. By 2049, it is planned to increase the total capacity of such stations to 1 GW.
