Nuclear fusion: Has there been a breakthrough and what will it mean?
A nuclear fusion reactor has reportedly created more energy than was put into it, for the first time ever. If the experimental results are confirmed, it will prove that fusion is a viable way to meet the planet’s growing energy demands by replicating the reaction that has been occurring at the heart of our sun for billions of years – with some caveats.

Ignition confirmed in a nuclear fusion experiment for the first time
We have ignition. An analysis has confirmed that an experiment conducted in 2021 created a fusion reaction energetic enough to be self-sustaining, which brings it one step closer to being useful as a source of energy.

Scientists propose a novel method for controlling fusion reactions
Scientists have found a novel way to prevent pesky magnetic bubbles in plasma from interfering with fusion reactions—delivering a potential way to improve the performance of fusion energy devices. And it comes from managing radio frequency (RF) waves to stabilize the magnetic bubbles, which can expand and create disruptions that can limit the performance of ITER, the international facility under construction in France to demonstrate the feasibility of fusion power.

Scientists have a new idea to make a fusion reactor practical
Scientists are hoping a new upgrade at U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) could finally make fusion power a reality — by harnessing the power of a silvery metal called lithium. As part of the Lithium Tokamak Experiment, a team of researchers are coating the inside walls of the reactor with lithium, the same stuff in the batteries in a wide range of electronics, to ensure that plasma remains super hot and highly pressurized inside the reactor — important conditions to get a shot at generating power from the reaction.

China targets nuclear fusion power generation by 2040
China aims to complete and start generating power from an experimental nuclear fusion reactor by around 2040, a senior scientist involved in the project said, as it works to develop and commercialize a game-changing source of clean energy.

Artificial intelligence accelerates efforts to develop clean, virtually limitless fusion energy
Artificial intelligence (AI), a branch of computer science that is transforming scientific inquiry and industry, could now speed the development of safe, clean and virtually limitless fusion energy for generating electricity. A major step in this direction is under way at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and Princeton University, where a team of scientists working with a Harvard graduate student is for the first time applying deep learning — a powerful new version of the machine learning form of AI...

A Future Without Fossil Fuels?
“Kingsmill Bond” certainly sounds like a proper name for a City of London financial analyst. He looks the part, too: gray hair expertly trimmed, well-cut suit. He’s lived in Moscow and Hong Kong and worked for Deutsche Bank, the Russian financial firm Troika Dialog, and Citibank. He’s currently “new energy strategist” for a small British think tank called Carbon Tracker, and last fall he published a short paper called “2020 Vision: Why You Should See the Fossil Fuel Peak Coming.”

Researchers turn liquid metal into a plasma
Most laypersons are familiar with the three states of matter as solids, liquids, and gases. But there are other forms that exist. Plasmas, for example, are the most abundant form of matter in the universe, found throughout our solar system in the sun and other planetary bodies. Scientists are still working to understand the fundamentals of this state of matter, which is proving to be ever more significant, not only in explaining how the universe works but in harnessing material for alternative forms of energy.

Can AI help crack the code of fusion power?
With the click of a mouse and a loud bang, I blasted jets of super-hot, ionized gas called plasma into one another at hundreds of miles per second. I was sitting in the control room of a fusion energy startup called TAE Technologies, and I’d just fired its $150 million plasma collider. That shot was a tiny part of the company’s long pursuit of a notoriously elusive power source. I was at the company’s headquarters to talk to them about the latest phase of their hunt that involves an algorithm called the Optometrist.

MIT is pouring resources into commercializing fusion power
A collaboration between the Massachusetts Institute of Technology and two energy companies is encouraging interdisciplinary research to fast-track the development of practical fusion power. Mechanical engineer Caroline Sorensen told an MIT blogger about her work on a “liquid immersion blanket,” which is a pool of molten salt that converts fusion reactions into heat and protects the rest of the reactor from damage.

Researchers just overcame a key barrier to fusion power
One promising approach to nuclear power is a type of reactor called a tokamak, which uses powerful magnetic fields to trap super-heated plasma in a bagel-shaped torus. An obstacle to making tokamak reactors viable is that the plasma gets extremely hot, reaching temperatures of up to 100 million degrees Celsius — as hot as the Sun. But according to Reuters, U.K. researchers say they’ve finally found a way to vent that heat safely.

Why nuclear fusion is gaining steam – again
Back when I studied geology in grad school, the long-term future of energy had a single name: nuclear fusion. It was the 1970s. The physicists I studied with predicted that tapping this clean new source of electric power by forcing two nuclei of hydrogen to combine and release massive amounts of energy, might be 50 years off.

Nuclear fusion on brink of being realised, say MIT scientists
The dream of nuclear fusion is on the brink of being realised, according to a major new US initiative that says it will put fusion power on the grid within 15 years. The project, a collaboration between scientists at MIT and a private company, will take a radically different approach to other efforts to transform fusion from an expensive science experiment into a viable commercial energy source. The team intend to use a new class of high-temperature superconductors they predict will allow them to create the world’s first fusion reactor that produces more energy than needs to be put in to get the fusion reaction going.

We Were Promised Fusion Energy
For the entirety of recorded history, humans have worshipped nuclear fusion. It's gone by different names over the millennia, of course: the Egyptians called it Ra, the Greeks called it Helios, and the Aztecs knew it as Tonatiuh. Today, most of us know it as the Sun, but leading physicists around the world regard it with the same sense of awe as our ancient ancestors. This is not because these physicists believe the Sun rides across the sky in a giant reed boat...

Scientists Are Getting Close To Controlling Fusion Power With Particle Beams
New research suggests scientists are getting close to using magnetic fields and powerful particle beams to control fusion reactions. Scientists say they’ve found a way to put sensors inside a fusion reactor and link them to a computer algorithm capable of directly controlling particle beams to regulate the reaction. Controlling the reaction with particle beams means physicists can prevent instabilities from degrading a magnetic field and ultimately shutting down a fusion reaction.
