According to a government official, scientists at a federal nuclear weapon facility have made potential breakthroughs on fusion research that could provide abundant energy in the future.
The Energy Department is expected to announce Tuesday the progress, stating that a “major technological breakthrough” was made at California’s Lawrence Livermore National Laboratory. Jennifer Granholm (the Secretary of Energy), along with other DOE officials, are expected to attend. The The Financial Times reported on SundayThe National Ignition Facility, also known as NIF, is a scientific breakthrough that uses giant lasers to simulate nuclear weapon blasts.
An anonymous government official spoke out to discuss results not yet made public. He said that the NIF fusion experiment achieved ignition. In this case, the fusion energy generated equals that of the laser that initiated the reaction. One energy gain is also known as ignition.
Another scientist who was familiar with the results and spoke anonymously to confirm that NIF had achieved ignition.
This development would increase the United States’ capability to keep its nuclear weapons in use without having to conduct nuclear tests. It could also open the door to future advancements that could lead to laser fusion being a carbon-free energy source.
Although it was not yet publicized, the news quickly spread to physicists, and other scientists who study fusion.
Stephen Bodner, a retired plasma scientist and critic of NIF, wrote, “Yesterday, a scientist friend sent a me a note stating that Livermore had exceeded Energy Gain by one just last Week. I will announce the result on Tuesday.” Email Monday morning. “They deserve praises for reaching their goal.”
Fusion energy: Hope for the future
The possibility of a solution to the world’s energy crisis is nuclear fusion. It replicates the sun’s process.
What is Fusion?
The thermonuclear reactions that power the sun, moon and other stars is called “fusion”. It’s the fusion between hydrogen atoms to create helium. The mass of the helium is slightly lower than that of the original hydrogenatoms. Thus, through Einstein’s iconic equation E = mc², this difference in mass is converted into a blast of energy.
A fusion that can safely be produced on Earth could indicate an energy source that doesn’t emit greenhouse gases such as oil and carbon dioxide, or dangerous radioactive waste that is long-lived, like current nuclear power plants.
How can you create a merger with no star?
Tokamak are donut-shaped reactors that have been used in most fusion efforts. Inside the reactors, hydrogen gas is heated to temperatures high enough that electrons are stripped from the hydrogen nuclei, creating what is known as a plasma — clouds of positively charged nuclei and negatively charged electrons. The plasma is trapped within the circular shape by magnetic fields, and the nuclei fuse together to release energy in the form neutrons.
Tuesday’s announcement however suggests a new approach. NIF is composed of 192 giant Lasers, which simultaneously fire an iron cylinder the same size as a pencil eraser. The cylinder heats to 5.4 million Fahrenheit. Once it vaporizes, an X-ray explosion triggers. Fusion occurs when hydrogen is fused to helium by the implosion.
What are the latest developments in laser fusion?
NIF was created at a cost $3.5 billion to conduct experiments that will help the United States keep its nuclear weapons safe from nuclear test explosions. It could also boost fusion research, which could lead to commercially viable power plants, according to supporters.
NIF was not initially able to create any mergers. In 2014, Livermore Scholars I finally reported successHowever, the power generated at the time was negligible. It was equivalent to what a 60-watt lightbulb would use in five minutes.
Livermore scientists reported last year a dramatic power jump of 10 quadrillion watts. This was 70% of the power of laser light hitting hydrogen targets.
The explosion, which was essentially a miniature hydrogen-bomb, lasted only 100 trillionthsof a second.
According to the Financial Times report, Livermore will report Sunday that the fusion energy generated in the latest experiment was greater than the amount of laser energy hitting the hydrogen target.
To make this happen, the fusion reaction has to be self-sustaining. This means that the flow from the hotspot in center of the pellet heats the surrounding hydrogen molecules and causes them to fuse.
What are the main obstacles to integration power
Important caveat: the claim only focuses on laser energy hitting an hydrogen target. NIF lasers have very low efficiency, meaning that only a small portion of the energy used to power them actually makes it into their beams.
Modern technologies, such as solid-state lasers, may be more efficient, but they are still far from 100% Fusion. To make this practical, the fusion energy output must at least be several times greater that the incoming laser.
Is Tuesday’s announcement a sign that we will soon have cheap fusion fuel?
number.
Even if scientists can generate more fusion bursts, there will still be huge engineering hurdles.
The NIF experiments were examined one at a time.
This concept is needed to build a practical fusion powerplant. It requires a high frequency of laser bursts, with new hydrogen targets being placed for each blast. The fusion reactions’ torrents of neutrons must be converted to electricity.
The laser complex fills the building with a footprint equal to three football fields—too big, too expensive, and too inefficient for a commercial power plant.
To mass-produce precision hydrogen targets, a manufacturing process must also be developed.
