China builds an 'artificial sun' thats temperatures of 180 MILLION degrees Fahrenheit & China creates artificial star 8,600 times hotter than sun’s Surface Area

The state-of-the-art reactor is designed to replicate the processes of the sun as part of a project to turn hydrogen into cost-effective green energy.It reached a key milestone this week when it hit 180 million F (100 million C) for the first time, which is believed to be the temperature at which nuclear fusion occurs.Scientists across the globe are locked in a race to build the world's first operational nuclear fusion reactor.The victor will unlock a source of near-limitless clean energy worth billions that some believe could save the planet from the climate change crisis.

Scientists at the China's Hefei Institutes of Physical Science announced their fusion machine reached hit 180 million F (100 million C) on Tuesday.This is more than six times hotter than the core of the sun, which peaks at around 27 million F (15 million C).Scientists believe that nuclear fusion occurs at 180 million F - causing  charged deuterium and tritium particles join together in a huge burst of energy.These particles normally repel each other, and enormous temperatures are required to overcome their opposing forces.The goal of the team's Experimental Advanced Superconducting Tokamak (EAST) is to better understand the process of fusion ahead of building a full reactor.Nuclear fusion reactors work differently to fission reactors because they fuse two nuclei, rather than splitting them.

Chinese scientists were able to create an artificial sun for 102 seconds at the Institute of Physical Science in Hefei.
Chinese scientists at the Institute of Physical Science in Hefei achieved something spectacular on Monday: the creation of a temporary artificial star three times hotter than the core of our sun.The artificial star was maintained for 102 seconds before the 49.999 million degree Celsius mass melted the core of the nuclear fusion chamber.The Experimental Advanced Superconducting Tokamak (East) project is part of global efforts in figuring out how to create a viable source of energy from nuclear fusion reactors, so as to provide a more efficient alternative to our current systems, which are heavily reliant on the use of fossil fuels.The project, which cost 300 million yuan (approximately $37 million), is attempting to solve a fundamental problem that scientists have had since the Industrial Revolution; that of creating more energy from machines than the initial input.Nuclear fusion works on heating a combination of two types of hydrogen gas - deuterium and tritium - to around 100 million degrees Celsius in order to create energy from the plasma that subsequently forms. This particular type of power has fascinated scientists since the early 1940s, and, with a planet rapidly depleting its fossil fuels, is increasingly being seen as best alternative power source for the future.Fusion reactors, and the energy they produce, have many benefits compared to their fossil fuel-based counterparts; they are carbon free, produce no nuclear waste, and cannot constitute a safety hazard. Most importantly, they are extremely efficient: 1 kilogram of fuel produced in this manner is equivalent to 100 million kilograms of fossil fuels, according to the Culham Centre for Fusion Energy.Monday’s experiment was a huge step forward in understanding how nuclear fusion works, as Chinese scientists were able to create an energy source for 102 seconds that was 49.999 million degrees Celsius.For context, that is 8,600 times hotter than our planet’s core.“The East project research results will be significant for the International Thermonuclear Experiment Reactor, in terms of basic research both in engineering technology and physics,” said Wan Yuanxi, the project head, in a press statement.Soviet technology, Chinese intuitionCreated in the 1950s by Soviet scientists Igor Tamm and Andrei Sakharov, a Tokamak (the “t” in “East” project) refers to a mass of plasma in the shape of a torus. To generate it, one needs a toroidal magnetic chamber; essentially a massive metallic doughnut-shaped chamber.An inside look into the toroidal magnetic chamber that was used to create the artificial star.

Most attempts to create nuclear fusion follow these lines, as plasma’s natural electrical conductivity can be used to theoretically contain it with magnetic fields.It does work; but currently no core has been created which can withstand such an awesome temperature for more than a few minutes.
So the challenge that faces the scientific community is how to sustain a temperature three times that of the core of the sun for long enough to be a viable source of power. And with our global deposits of fossil fuel rapidly dwindling away, it’s a problem that requires a solution soon.
