British scientists announced that they had broken the previous record for creating fusion energy, hailing the feat as a “landmark” on the long road to generating a power source that is both cheap and clean. Nuclear fusion is the same technique that the sun uses to generate heat. researchers believe that it can one day aid in the fight against global warming by providing a copious, safe, and ecologically beneficial source of energy.
In January According to the atomic energy authority, During an experiment scientists produced 59 megajoules of sustained energy, more than doubling the previous high of 1997. The observation is the surest sign of fusion energy’s ability to create safe and sound low-carbon electricity everywhere in the world.
A tokamak is a donut-shaped apparatus used for experiments and the JET site is the world’s largest functioning one. Inside the machine, a small amount of fuel made up of deuterium and tritium (both hydrogen isotopes) is heated to temperatures 10 times higher than the sun’s core to form plasma. As it spins around, fuses and releases massive energy in the form of heat. it is held in superconducting electromagnets. Fusion is essentially safe since it does not cause a chain reaction. It produces roughly four million times more energy per pound (grams) than coal, oil, or gas and produces essentially no waste.
The results of the experiment show that fusion can be created for five seconds but lengthier durations are needed before the process can be used as a traditional power source. British researchers stated that If we can keep fusion going for five seconds then we may keep it going for five minutes, then definitely five hours as we ramp up our operations in future machines.
ITER, a bigger and more complex version of JET, is now being built in southern France, and the British researcher’s data will be crucial once it is operational as soon as 2025. Every year, about 350 scientists from European nations and others from across the world take part in JET experiments. Meanwhile, alongside researching devices like JET and ITER, so-called DEMO fusion power reactors to generate electricity to the grid are being constructed.
Global cooperation on nuclear fusion has traditionally been close because of deposited nuclear fission which is used in atomic power plants, the technology cannot be weaponized. Although dozens of fusion reactors have been created since they were initially invented in Soviet Russia in the 1950s none has yet produced more energy than has been put in. The milestone results were also lauded by British Scientific researchers
