Scientists have successfully tested a world-first concept that could clear one of the major hurdles in developing fusion energy. Initial results from the UK Atomic Energy Authority’s (UKAEA) MAST Upgrade experiment indicate the effectiveness of an innovative exhaust system designed to make compact fusion power plants commercially viable. Experts say that with no greenhouse gas emissions and abundant fuels, fusion can be a safe and sustainable part of the world’s future energy supply. Fusion energy is based on the same principle by which stars create heat and light. The reactor superheats a gas, which forces electrons out of the atoms within the gas and creates a plasma. This plasma is contained by a powerful magnetic field created by a device called a tokamak.
