China can successfully build the artificial Sun.

Chinese scientists can produce three times more hot hydrogen gas than the Sun's core by using nuclear fusion and maintaining this temperature for 102 seconds.

This groundbreaking success helped China step ahead in a global race to harness artificial solar power , South China Morning Post reported on February 5. Artificial solar is thought to be cleaner and almost endless, while Earth's natural energy reserves are rapidly depleting.

According to the Institute of Physical Sciences in Hefei, China, an experiment was conducted in early February on the Tokamak superconducting experimental reactor (EAST), heating hydrogen gas in the form of plasma to heat. At 49,999,000 degrees Celsius, the Sun core is estimated to have a temperature of only about 15 million degrees Kelvin. This super high temperature can be maintained for 102 seconds.

The temperature that Chinese scientists have achieved is almost the same as a medium-sized thermonuclear explosion. The purpose of the experiment is to repeat the conditions for nuclear fusion occurring deep within the Sun.

Another experiment conducted in the last decade created temperatures higher than this number, but it did not last as long as the results just announced in China, and people could not repeat the experiment. That experience.

Meanwhile, physicists in Japan and Europe have reached the same temperature as the research team in China, but the time to control this temperature lasts no more than a minute due to concerns about the furnace crisis. react.

EAST reactor invented by Soviet scientists to control nuclear fusion in electricity production. The EAST reactor uses a strong magnetic field to confine plasma gases in a toroidal vacuum chamber. Inside, gas atoms are controlled by a superconducting magnet.

However, controlling hydrogen gas in plasma state is not easy. During the past 60 years, no EAST reactor has been able to maintain hydrogen gas in plasma state for more than 20 seconds. At ultra-high temperatures, nuclear reactions must occur correctly and must not be in direct contact with plasma, otherwise it will melt or evaporate immediately.

With this result, Chinese scientists need a few more years to successfully build an artificial Sun that can operate stably for decades.
