Nuclear fusion milestone: China’s BEST reactor prepares for first electricity tests

China's advanced nuclear fusion reactor BEST reached a major construction milestone with the installation of its massive Dewar base, a 400-tonne vacuum-insulated vessel that will house the device's superconducting magnets at extremely cold temperatures. The reactor aims to become the first fusion device to generate electricity by 2030, initially targeting enough power to light a bulb. This would mark a significant breakthrough in fusion research, which has historically focused on creating plasma conditions rather than converting fusion reactions into usable electricity.
