2nd Nuclear Fusion Breakthrough

Please refer to the previous post on the first fusion breakthrough...

This is the second time that the core of a fusion reactor has given out more energy than it has taken in, but significant challenges remain, yet it could be just a tiny step towards the goal of limitless energy.

By firing the world's most energetic laser beam to briefly transform a pellet of hydrogen isotopes into a fiery plasma, the physicists produced a higher net-energy gain than they did on their first attempt last year.

"Since demonstrating fusion ignition for the first time at the National Ignition Facility in December 2022, we have continued to perform experiments to study this exciting new scientific regime. In an experiment conducted on July 30, we repeated ignition at NIF," the researchers said in an emailed statement. "As is our standard practice, we plan on reporting those results at upcoming scientific conferences and in peer-reviewed publications."

Scientists have warned that getting more energy out from the entire reactor than was put in could take several decades, so advancements likely won’t arrive in time to help humanity fight climate change. These experiments do, however, provide compelling evidence that the power of stars could one day be used to power human life on Earth.

US scientists achieve net energy gain in fusion reaction for second time​

Scientists work to develop fusion reaction as they look for limitless clean and safe source of power to help curb climate change.

This illustration provided by the National Ignition Facility at the Lawrence Livermore National Laboratory depicts a target pellet inside a hohlraum capsule with laser beams entering through openings on either end. The beams compress and heat the target to the necessary conditions for nuclear fusion
Scientists in the United States have achieved net energy gain in a fusion reaction for the second time since December in efforts to find a clean source of energy, according to the Lawrence Livermore National Laboratory.
Scientists at the California-based lab repeated the fusion ignition breakthrough in an experiment in the National Ignition Facility (NIF) on July 30 that produced a higher energy yield than in December, a Lawrence Livermore spokesperson said on Sunday.
Final results are still being analysed, the spokesperson added.

Nuclear fusion reaction involves combining two atomic nuclei to form a single heavier one, releasing an enormous amount of energy. Scientists have known for about a century that fusion powers the sun and have pursued developing fusion on Earth for decades, as they look for limitless clean and safe source of power to help curb climate change.
If technology around fusion reaction is further advanced, it can be used to produce power at an industrial scale.
The US Energy Department called it “a major scientific breakthrough decades in the making that will pave the way for advancements in national defence and the future of clean power”.

The scientists focused a laser on a target of fuel to fuse two light atoms into a denser one, releasing the energy.
That experiment briefly achieved what is known as fusion ignition by generating 3.15 megajoules of energy output after the laser delivered 2.05 megajoules to the target, the Energy Department said.
In other words, it produced more energy from fusion than the laser energy used to drive it, the department said.
Nuclear scientists outside the lab said the achievement will be a major stepping stone, but there is much more science to be done before fusion becomes commercially viable

True... But you never know. Just 10 years ago this was impossible. Now someone demonstrated at least it's not impossible. No one can expect anything for the next two or three decades. Scientists are aware of it.
A competing fusion reactor design is under construction. The International Thermonuclear Experimental Reactor (ITER) is under construction in France. The ITER reactor uses a Tokamak reactor design, whose main distinction is the use of a magnetic field to constrain hydrogen into a very concentrated space, while heating up that hydrogen to insanely high temperatures. The ITER reactor is slated to be "switched on" in 2025. The engineering lift for this is immense. The project uses 3,000 tons of superconducting magnets, connected by 200 kilometers of superconducting cables, all kept at minus-269 degrees C by the world’s largest cryogenic plant. The temperature needed to get the hydrogen atoms to fuse is thought to be about 150 million degrees C, or 10 times hotter than the sun.
