The World's Largest Nuclear Fusion Reactor Is Finally Being Built

After 35 years of preparation and delays, scientists have finally started to assemble the world’s largest nuclear fusion reactor in France. Funded by six nations, including the US, Russia, China, India, Japan, and South Korea, ITER will be the world's largest tokamak fusion device with an estimated cost of ~$24 billion and capable of generating about 500 MW of thermal fusion energy as early as 2025.
