Physicists have engineered a way to make hydrogen gas that heats up to a whopping 50 million C. And crucially, they've been able to maintain that temperature for a record 102 seconds. While it might not sound hugely impressive, the only other attempt to reach this high a temperature was done by German scientists, who managed 80 million C - but only for a fraction of a second. Physicists believe this new discovery could mean the end of relying on fossil fuels. This is because scientists can harbour nuclear energy from the gas, providing unlimited clean energy. The tests were carried out using a machine called the Experimental Advanced Superconducting Tokamak (EAST) - the reactor that produces the high temperature substance - at the Institute of Physical Science in Hefei, China. It reached highs of 50 million Kelvins - this is compared to the surface of the sun, which comes in at around 15 million Kelvins. The gas was kept in the nuclear chamber for well over a minute, helped along by creating a magnetic field to keep it suspended in the doughnut-shaped contraption. This magnetism appears when scientists superconducted the coils surrounding the structure at the same time as driving an electrical current through the plasma. Their goal was to reach highs of 100 million Kelvins for 1,000 seconds, which is around 17 minutes. But even though they didn't achieve their target, this latest feat is hugely significant in ridding the world of fossil fuels. Earlier this month, researchers found that burning fossils such as petrol and coal has meant the Atlantic Ocean has soaked up 50 percent more carbon dioxide than normal in the past decade.
