The problem of finding a clean source of power supply is trying to be solved by using cleaner wind, wave, solar, hydro and nuclear power. But the power generation system capable of producing the highest power with clean side effects is nuclear fusion. Nuclear fusion as if occurring on the surface of the sun is being reproduced in humans using a tokamak machine.
Tokamak EAST in China now holds the world record of operating for 1056 seconds (17.6 minutes) at a temperature of 70 million degrees Celsius which is much hotter than 15 million Celsius on the surface of the sun. In May last year, EAST reached a temperature of 120 million degrees Celsius for 101 seconds which is also a world record.
There is still a lot of research to be done before nuclear fusion power plants will become a reality because it is difficult to maintain the plasma at a high temperature and the energy consumption to produce it is very high. But if it becomes a reality, the issue of coal use, nuclear materials and hydro dams drowning habitats will be a thing of the past.
