ITER is one of the most ambitious scientific in the world. It is being built in south of France and involves the cooperation of countries, including the European Union, the United States, , India, Japan, Russia, and South Korea. The goal ITER is to show that nuclear fusion can used as a safe and powerful source of energy.

Nuclear fusion is the process that powers sun and stars. It happens when two light , like hydrogen, join together to form a heavier . When this happens, a huge amount of energy released. Unlike nuclear fission, which is used in nuclear power plants, fusion does not produce dangerous waste or risk of explosion. It also uses that can be made from seawater, which means could provide almost unlimited energy for the future.

ITER reactor is a giant machine called a . It is shaped like a doughnut and uses magnetic fields to hold extremely hot plasma inside. plasma can reach temperatures of over 150 million Celsius, about ten times hotter than the center the sun. Scientists will try to keep this stable long enough to produce more energy than needed to heat it.

When ITER begins operation the 2030s, it will not generate electricity yet, it will be a major step toward future power plants. The success of ITER could change world's energy future by giving us a clean, , and almost endless energy source. This international project how countries can work together to solve global for the good of all humanity.
