To prepare for the future, China is experimenting with a prototype “artificial sun,” called Experiential Advanced Superconducting Tokamak (EAST). In a recent test, a fusion reactor ran for almost 20 minutes at 70 million degrees Celsius. However, the core of the Sun reaches a temperature of 15 million degrees Celsius. It uses nuclear fusion, a less explored method of harnessing nuclear energy.
The setup simulates the nuclear reactions occurring inside the sun, using hydrogen and deuterium gas as fuel. These experiments (artificial sun) might lead to a “never-ending supply of clean energy.”
