Scientists They confirmed that on August 8, 2021, they were able to ignite the same chemical reaction that powers the Sun by pumping out more energy than the entirety of it. we The electrical network in a small capsule of gold.
For a split second, the power of 192 laser beams equals the same energy as thermonuclear fire the sun It ignited, which is really amazing.
The breakthrough in fusion energy means we are now closer than ever to being able to harness chemical reactions with enough gravity to power the Sun, which generates energy by throwing hydrogen atoms together, thus producing helium.
It is also worth noting that the fusion reaction created by the scientists was autogenous, which means that it did not immediately fade away.
Nuclear fusion occurs when two atoms combine, forming a heavier atom and unleashing a massive energy explosion. This process is common in nature, but it’s really hard to replicate in labs – mainly because an incredibly high-energy environment is needed to ensure the reaction continues.
The experiment was conducted by the National Ignition Facility at Lawrence Livermore National Laboratory in California and detailed in three newly published papers—one in physical review messages and two in physical review.
While the papers argue that researchers have achieved “ignition” – indicating the possibility of nuclear fusion – a practical fusion reactor remains elusive.
If scientists are able to develop fully functional fusion power plants, the sites will produce dozens of energy using hydrogen from water as fuel.
This means that the only waste generated will be helium and the radiation hazard will be eliminated.
By comparison, contemporary nuclear power plants use nuclear fission to generate energy, which is done by splitting the nuclei of heavy elements such as uranium.
Last year’s experiment used more than a quadrillion watts of power, a massive amount of power released for just a split second.
Of the groundbreaking experiment, Omar Assar—the chief scientist of the self-confinement fusion program at Lawrence Livermore National Laboratory—said: “The record shot was a major scientific advance in fusion research, proving that in vitro fusion ignition is possible in NIF.”
He added, “Achieving the necessary conditions for ignition has been a long-standing goal of all self-confinement fusion research and opens up access to a new experimental system where the self-heating of alpha particles bypasses all cooling mechanisms in fusion plasmas.”
