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.
