For several years now, researchers at Livermore National Laboratory in California have been trying to recreate nuclear fusion, the process by which the sun generates energy. Since 2010, there have been not so many results, but recently scientists have done the impossible.
Professor Omar Harikane published a report in which he said that his team was able to carry out an artificial nuclear fusion reaction with a positive efficiency. Moreover, the synthesis did not turn into a hydrogen bomb - which is very good, because otherwise the laboratory would simply be wiped off the face of the Earth. Harnessing such destructive power as a green energy source is one of the most challenging tasks of science.
Dr. Harikein and his colleagues succeeded in achieving a positive result thanks to an array of 192 powerful lasers with a power of 500 trillion watts. Laser energy was focused on a tiny sphere filled with a mixture of deuterium and tritium. As a result of the impact on a droplet of cryogenic fuel with an energy of 1, 9 MJ, a nuclear fusion reaction arose with the release of more energy than was expended - for the first time in the history of mankind.
While it sounds like scientists have found the Holy Grail of inexhaustible energy, it is not entirely true. It would be more correct to say that an important checkpoint was passed. One step is missing in which the fusion reaction would actually generate enough energy to compensate for the operation of the lasers. Now the reaction only generates more energy than it absorbs.
So, if you were waiting for the emergence of a pure source of infinite energy from laboratory stars, you will have to wait a little longer. Nevertheless, scientists are one step closer to the final goal and are full of optimism.
