Huge, costly, enormous effort, ITER nuclear fusion far from ready

France’s global nuclear fusion device a puzzle of huge parts, AP, By ELAINE GANLEY. 29 Jul 20,
“…….. Billed as the world’s largest science project, ITER is gigantic. The circular device, called a tokamak, has a 30-meter circumference, stands 30 meters (100 feet) high, and is made up of more than a million parts constructed in numerous countries. ………Some pieces transported to France weigh several hundred tons. Tools to put the reactor together match that size, with giant lifts that must transfer components over the walls and down into “the pit.” A key component being built by the U.S., the Central Solenoid, is the most powerful of ITER’s numerous magnets. Together, they will be strong enough to lift an aircraft carrier. The project begun in 2006 is far from over. The experimental reactor is to head for another landmark moment in five years, described as a “trial run” when scientists launch what is called “First Plasma” showing that the machine functions, including magnetic fields and other operations……
The project’s estimated cost just for the EU was about 20 billion euros ($23.5 billion), Bigot told reporters. He said a full price tag was difficult to estimate because participating countries make their own contributions. https://apnews.com/c9e1780864431c3edcd1cc2c17568c54
