Germany is about to start up a mons­ter machine that could revo­lu­tio­nize the way we use energy

For more than 60 years, scien­tists have drea­med of a clean, inex­haus­tible energy source in the form of nuclear fusion.

[…] Last year, after 1.1 million construc­tion hours, the Insti­tute comple­ted the world’s largest nuclear fusion machine of its kind, called a stel­la­ra­tor.

They call it this 52-foot wide machine the W7-X.

And follo­wing more than a year of tests, engi­neers are finally ready to fire up the $1.1 billion machine for the first time, and it could happen before the end of this month, Science repor­ted.
