Nuclear fusion has been achieved using a new projectile technique that accelerates fuel to 200 times the speed of sound. First Light Fusion, a UK based start-up, used a hyper-velocity gas gun to launch a projectile at a specially designed target. This in focuses the energy, accelerating fusion fuels, such as deuterium, to over 70 km per second, starting the fusion reaction. Fusion is a process where two light atomic nuclei combine to form a single heavier one while releasing massive amounts of energy. The team behind the method hopes to create a power plant that could generate around 150 megawatts of electricity by the 2030s.
