The colossal ITER fusion power facility is halfway finished

From Engadget - December 6, 2017

ITER is the logical production of "what if we threw a bunch of money and scientists from all over the world at the fusion problem." It's funded by seven bodies: Primarily the EU, with small stakes from the US, India, China, Russia, Japan and South Korea. Construction began in 2013, but delays have led to a rough road for the massive project, leading to an inflated $22 billion price tag, ITER estimated back in March. But given that the project will attempt to replicate the energy reactions found in the sun and hydrogen bombs, complexity is expected.

Now ITER is halfway built and expected to finish construction in 2021. The installation aims to start experiments to produce fusion reactions in 2025. ITER will use a method called hydrogen fusion, The New York Times' report on the facility describes: Deuterium and tritium nuclei fuse to form helium, which will release a lot of energy that bounces around the reactor chamber and strikes its walls, which makes heat. But since the installation will only prove the concept, it wo not turn it into energy.
