Artificial sun made by China will ready to shine on this year


IllustrationIllustration - After announcing the plan to make an artificial moon/sun, China recently confirmed that its artificial solar project will be ready to shine on this year. In November, China announced an artificial solar project called Experimental Advanced Superconducting Tokamak (EAST). This project is designed to mimic the nuclear fusion process used by the sun to produce energy.

The sun made in China is targeted to be completed this year and has produced an electron temperature of 100 million Celsius in the trial process. This number is the temperature needed to maintain the fusion reaction. Official from China's National Nuclear Company, Duan Xuru, said the engineering team will complete the construction of Tokamak HL-2M in 2019.

"Artificial solar plasmas consist of electrons and ions. Tokamak has reached an electron temperature of more than 100 million degrees Celsius in the core plasma and the temperature of the ion reaches 50 million degrees Celsius" Xuru explained as quoted by the Global Times. He said if the device developed could record seven times hotter than the temperature of the original Sun ion.

Quoting Science and Technology Daily, the temperature of electrons and ions is only one of three challenges for utilizing nuclear fusion. Two other challenges are related to fusion in limited space in the long term and a high level of density. "To increase the temperature of ions to more than 100 million degrees Celsius, we need higher device parameters to inject and absorb more energy" he explained.
