Germany is getting closer to nuclear fusion—the long-held dream of unlimited clean energy

 

German scientists today will set about the first steps towards what has become the Holy Grail of energy—nuclear fusion, which has the potential for unlimited amounts of clean power. There are a number of challenges to harnessing this power—researchers need to build a device that can heat atoms to temperatures of more than 100 million °C (180 million °F).

After almost nine years of construction work and more than a million assembly hours, researchers from the Max Planck Institute in Greifswald are set to do just that by heating a tiny amount of hydrogen until it becomes as hot, hopefully, as the center of the Sun. Continue reading
