In a large complex located at Greifswald in the north-east corner of Germany, sits a new and unusual nuclear fusion reactor awaiting a few final tests before being powered-up for the very first time.

On May 22, researchers achieved a major milestone in the pursuit of clean, limitless energy. At the Wendelstein 7-X facility in Germany, scientists set a world record for sustaining a fusion-grade ...

Germany's Wendelstein 7-X - the world's largest stellarator-type fusion device - has achieved a world record in a key parameter of fusion physics: the triple product. This value now exceeds previous ...

Scientists in Germany began an experiment which (they hope) will bring us closer to the dream of nuclear fusion power—a safer, cleaner form of nuclear energy. Nuclear fusion is, after all, what powers ...

Scientists in Germany fired up a doughnut-shaped reactor to heat hydrogen to the point of becoming plasma, which lasted for just a split second. The successful “Wendelstein 7-X” stellarator experiment ...

The Wendelstein 7-X stellarator has successfully completed its first stages of research, heating plasmas to temperatures of 100 million degrees Celsius and achieving pulse lengths of six seconds.

If there is a holy grail of humankind’s quest for clean and limitless energy, it is to replicate the process that has been powering our sun for the past 4.5 billion years. Unlike nuclear fission — the ...

On May 22, the latest experimental campaign concluded at the world's most powerful nuclear fusion device of the stellarator type. Through collaboration between researchers from Europe and the U.S., ...
