Germany's massive nuclear fusion machine just produced its first hydrogen plasma This is huge. German scientists have just switched on the Wendelstein 7-X (W7X) stellarator - the largest nuclear fusion machine of its kind - to successfully produce and sustain hydrogen plasma for the first time. Why is this such a big deal? The production of hydrogen plasma is key to harnessing the clean, limitless energy of nuclear fusion - the process that powers our Sun. If we can achieve controlled nuclear fusion, it would quite literally change the world, because it would replace fossil fuels and nuclear fission facilities as a cheaper, more efficient, and more sustainable source of energy. "It’s a very clean source of power, the cleanest you could possibly wish for. We’re not doing this for us, but for our children and grandchildren," one of the team, physicist John Jelonnek from the Karlsruhe Institute of Technology, told the Associated Press . Nuclear fission...
