"Artificial Sun" China is ready to launch a thermonuclear reaction

The experimental superconducting tokamak version reached a new temperature record at the Institute of Physical Sciences at the Chinese Academy of Sciences in Hefei. Scientists have heated plasma up to 100 million degrees. This means that the equipment known as the "Artificial Sun" informally produces 6 times more heat than the Sun's core, which gushes only at 15 million Kelvin.

The dream of a nuclear physics scientist – to achieve a controlled thermonuclear reaction and create an endless source of energy – has gone further. There may not be a record of higher temperatures – the current indicator is enough to start trying to connect the hydrogen atom's nucleus and trigger a chain reaction. In particular, this is a minimum number – and now, beyond that limit, you can start the boldest experiment.

This device uses more than 10 MW of power, and when researchers optimized the theoretical calculations and simulated different heating techniques and continued plasma control, plasma energy increased to 300 kJ. The temperature of electrons in plasma has increased by more than 100 million degrees. Dozens of factors limit the reoccurrence of thermonuclear reactions in the sun's core on Earth. Because we cannot restore all conditions in a star, we have to find another way. Tokamak is designed to curb the greatest energy in plasma which is controlled by a magnetic field, much higher than in the Sun. Only under such conditions here, on Earth, can a controlled thermonuclear reaction be controlled by itself.
