German lab takes further step closer to nuclear fusion
Following nine years of construction and testing, researchers at the Max Planck Institute for Plasma Physics in Greifswald injected a tiny amount of hydrogen into a doughnut-shaped device — then zapped it with the equivalent of 6,000 microwave ovens.
The resulting super-hot gas, known as plasma, lasted just a fraction of a second before cooling down again, long enough for scientists to declare the start of their experiment a success.
