I think it's both terrifying and exciting that we're re-creating the core of the Sun in a machine in Germany.
This November, the experimental fusion reactor W7-X will be starting its engines. This is the first viable fusion reactor that can actually produce energy. Fusion is what happens inside the Sun, where the temperature of the core is about 15 million degrees Celsius. But W7-X will need to generate temperatures of about 100 million degrees.
Fusion reactors will be a cleaner and more efficient source of energy.
