For the first time in history, scientists have achieved the impossible: creating a positive energy yield from nuclear fusion – the same energy that powers the sun.
Announced by the US Department of Energy this week, the breakthrough of nuclear fusion brings humanity a step towards unlimited, carbon-free and clean renewable energy that could “revolutionize the world”.
“Simply put, this is one of the most impressive scientific feats of the 21st century,” said US Energy Secretary Jennifer Granholm about the achievement by scientists at the Lawrence Livermore National Laboratory in California.
“This enhances our national security and the ignition allows us to replicate certain conditions found only in the stars and the sun.”
Star power
The “ignition” of fusion is described by Lawrence Livermore as “the moment when the energy from a controlled fusion reaction exceeds the rate at which the loss of x-ray radiation and the conduction of -electrons cool the implosion” – or as much or more energy flows “out” than “in”.

A positive energy gain means that the fusion reaction achieved by the scientists generated more energy than was input to trigger that reaction.
The researchers had been working on the technology for decades, Granholm said – adding that the impact of their work would help US industries nationwide.
Fusion versus fission
Nuclear fusion is considered by some to be the energy of the future because it produces no greenhouse gases, leaves little waste and has no risk of nuclear accidents. Read also : Politics.
It differs from fission, the technique used in nuclear power plants, because it fuses two atomic nuclei together instead of splitting one.
Scientists at Lawrence Livermore focused a laser on a target to combine two light hydrogen atoms into one denser one.
When the two light atoms collide at very high speeds, they fuse together into one heavier element, helium, releasing energy in the process.
“Controlling the energy source of the stars is the greatest technological challenge humanity has ever taken on,” tweeted physicist Arthur Turrell, author of The Star Builders.
Big job ahead
However, scientists also say there is much more work to be done. This may interest you : UW Health experts recommend stress management. Producing fusion reactions is only possible by heating matter to over 100 million degrees Celsius.
“So we have to find ways to isolate this extremely hot matter from anything that could cool it,” said Erik Lefebvre, project leader at the French Atomic Energy Commission.
“This is the problem of restraint.”
Fusing atoms together also takes an enormous amount of energy, both in seeking to achieve a reaction and in suppressing it.
