Researchers at Tokamak Energy have captured for the first time a real-time, high-speed video of plasma behaviour inside their ST40 spherical tokamak, tracking visible green and red light emissions as the fusion process occurs. This visual insight comes via a camera operating at thousands of frames per second, offering unprecedented detail of how the plasma evolves, interacts with the surrounding lithium blanket and outer regions, and ultimately radiates energy. The imaging enables scientists to observe how the ultra-hot core transitions outward into cooler zones, how magnetic confinement shapes the plasma behaviour, and how impurities or outer-region interactions influence the process. By giving a ‘star-in-a-donut’ view of fusion in action, this breakthrough adds a new diagnostic tool to the development of fusion energy, helping engineers refine the magnetic confinement, optimise plasma stability and better understand the heat and light flows at play. It was slowed down by 100x. All this was for 0.3s A tokamak is one of the most advanced devices ever created to achieve controlled nuclear fusion, the same process that powers the Sun. Its goal is simple in principle but incredibly challenging in practice: heat a gas until it becomes plasma, raise that plasma to over 100 million degrees, and confine it long enough for hydrogen nuclei to fuse and release energy. Because no material container can survive such temperatures, a tokamak uses powerful magnetic fields to hold and shape the plasma like an invisible cage. The device has a distinctive doughnut-shaped (toroidal) chamber surrounded by magnetic coils. When the machine is switched on, electric currents and external magnets work together to create helical magnetic fields that trap the plasma and keep it away from the walls. As the plasma spirals around these magnetic lines, it heats up dramatically. Additional heating comes from methods like radio-frequency waves and neutral-beam injection, pushing the plasma toward the extreme temperatures needed for fusion. Inside this tightly controlled environment, hydrogen isotopes such as deuterium and tritium can collide and fuse, releasing fast neutrons and a burst of energy. The goal of tokamak research is to reach a point where the fusion reactions produce more energy than the system consumes, a milestone known as “net energy gain.” Modern machines like ITER, JET, and Tokamak Energy’s ST40 are bringing this vision closer, using advanced diagnostics, superconducting magnets, and increasingly stable plasma control. 👉

Here we go… This is the moment our ST40 centre column is lifted out. A bit like open-heart surgery on a tokamak. It’s a delicate operation, and a huge milestone for ST40. The centre column has had a tough life, acting as the core of the toroidal magnetic field coil in the world’s highest-field spherical tokamak. After more than 5,000 plasma pulses, it has helped generate magnetic fields above 2 Tesla at the plasma core, confining plasma at temperatures of more than 100 million °C, the threshold for #fusion. Next up, we install the new and improved centre column built by our partners at The Rockwood Group. This is all part of ST40’s major upgrade programme with U.S. Department of Energy and Department for Energy Security and Net Zero, helping transform it into one of the most reactor-relevant fusion devices in the world. What began as an experimental tokamak is becoming something much bigger: a customer testbed for the technologies and expertise needed to put #fusionenergy onto the grid⚡ And for anyone wondering what the centre column actually does… 👇 It forms the inner limb of each turn of the toroidal field coil. Its 24 wedges each carry up to 200 kA of current, generating the powerful magnetic fields needed to confine the plasma. Wrapped around the wedges, a 192-turn central solenoid helps drive and sustain the plasma current, after merging-compression start-up. An impressive piece of equipment with an equally impressive track record! #Fusion #FusionEnergy #Innovation

Taming the Edge: How lithium could help us control #fusion plasmas. This video captures the first flashes of lithium being injected into the #plasma of our ST40 tokamak, marking the start of our exploration into its effects. Why lithium? In fusion research, we aim for H-mode, a high-performance state with improved plasma confinement. Future fusion power plants are expected to operate in this mode. But H-mode brings a challenge: ELMs (Edge Localised Modes) are bursts of energy at the plasma edge, similar to mini solar flares. These can reduce plasma temperature and damage the divertor with intense heat and particles. Pioneering work by PPPL and others has shown that lithium can suppress ELMs and increase energy confinement time, leading to higher temperatures. On ST40, we’re currently injecting lithium powder during plasma shots to explore its effects. As part of our upcoming ST40 LEAPS upgrade – in partnership with the U.S. Department of Energy and Department for Energy Security and Net Zero – we’ll go further, coating plasma-facing components with solid lithium using the ‘lithium evaporation’ technique. We’ll be experimentally testing several mechanisms. One key focus is how lithium absorbs hydrogen isotopes and reduces their recycling back into the plasma, lowering the density at the plasma edge, leading to a more stable edge pressure gradient. We’re starting to understand more about lithium’s effect on plasma performance, and early results show lithium isn't getting into the plasma core, which is good news for avoiding diluting the fusion fuel in future plants. The physics is complex, and we’re still learning. But each step brings us closer to fusion energy. By incorporating lithium into ST40, the world’s highest field spherical tokamak, we’re advancing our understanding of this critical enabling technology. #Fusion #FusionEnergy #Innovation #Limitless #EnergyTransition

Helion energy is building what will be the world’s first commercial fusion power plant, scheduled to be finished in 3 years. Great interview by Lex Fridman with David Kirtley (CEO of Helion). Most power plants are heat engines. You burn fuel or run fission, boil water, spin a turbine, and get about 35% electricity while the rest leaves as waste heat. Helion flips the flow. The fusion reaction makes charged particles that push back on a magnetic field tied to a capacitor bank, so you get direct electricity instead of a steam loop. That path can reach about 85% efficiency from fusion energy to electrical output, which means less conversion gear and tighter control over power delivery. 🧪 How the machine works A giant capacitor bank drives coils that both accelerate and squeeze plasma. Two plasmas, deuterium plus helium‑3, are launched from opposite sides and collide in the center. By rapidly reversing the magnetic field in about 1 microsecond, the plasma self-organizes into a field‑reversed configuration that traps itself. Then the machine compresses it hard. Fusion happens, new charged particles appear, and their pressure pushes the magnetic field so the system dumps energy back into the capacitors. It is pulsed, up to 100Hz in tests, so each shot is a clean measure of input versus recovered electricity. 🛡️ Safety and waste There is no chain reaction. The device only holds about 1 second of fuel at any time, so stopping the drive stops fusion. X‑rays and some neutrons exist during operation, so you use shielding and standard controls, similar to particle‑accelerator facilities. When the pulse stops, the radiation source stops. 🖥️ Why data centers care The output is high‑voltage DC sitting on capacitors. You can invert to AC for the grid, or route DC with fewer conversions into rectifier buses for racks. That cuts losses and simplifies backup. The company is targeting 2028 for a first grid-tied plant for a large buyer, which lines up with growing AI power needs. 🧩 What is still hard Helium‑3 is scarce on Earth, so you must produce it or source it. This fuel also likes higher temperatures, roughly 200M-300M degrees, so the pulsed magnets and power electronics must be very fast and very tough. Stability is managed by giving the plasma enough “spin” and length so it behaves like a fast top that stays upright, plus thousands of synchronized switches that fire with microsecond timing. If this architecture keeps showing pulse gain and high‑efficiency recovery, you get a compact generator that skips steam, feeds a capacitor, and delivers clean power in the exact format modern compute wants.

My conversation with John Arnold (John Arnold). Few people I've spoken with have as wide a view of the global system as John. He was one of the most successful energy traders of all time, and after stepping away from markets he built a foundation devoted to solving America's most critical systemic problems in a principled way. John's recent trip to China was the catalyst for this conversation, and I feel lucky we all get to learn from him. We discuss: - His trip to China and what it taught him about robotics, AI, and EVs - What it takes to be the best (and what it costs) - Building the best seat in the market - The state of energy markets today - NIMBYism as the impediment to progress - What he thinks about the wave of nuclear startups - Fixing America's broken systems: healthcare, criminal justice, education, and journalism Enjoy!

A PhD student built a working nuclear fusion reactor in his garage, let an AI run it, and 400 thousand dollars later he works for Elon Musk. he posted it once. that single post ended with a grant in his account and a job offer from the most powerful man on earth. not a simulation. not a school project. an actual device that fuses atoms, sitting where his car used to be. fusion is the thing governments have been chasing for 70 years with billion dollar labs. the hard part was never the reactor itself. it was the control. the plasma inside has to be held at conditions hotter than the core of the sun, and it shifts and collapses in milliseconds. no human can react fast enough to keep it stable. so he stopped trying to do it himself. he handed the control loop to an AI. the model reads the sensor data hundreds of times a second, predicts how the plasma is about to move, and adjusts the magnetic fields before it ever drifts out of line. it does not wait for the plasma to misbehave. it sees it coming and corrects it before it happens. the same reaction-before-the-event speed no person could ever match. this is the exact kind of build people are tearing apart inside Neuro Club. not to make reactors, but because the workflow is identical for anything hard. let the AI run the loop, predict the problem, fix it before it breaks. same playbook whether it is plasma or a business. then the post went out. within days Elon's fusion team reached out. they did not ask him to interview for an entry role. they handed him a 400 thousand dollar grant and pulled him onto the team building this at scale. one garage build turned a PhD student into an operator for the most ambitious man alive. here is the part that should stop you. he was one guy with a PhD, a garage, and an AI model doing the job that entire teams of physicists used to fail at. the AI was not assisting him. it was the operator. he built the hardware. the machine ran it. and that was enough to get noticed at the very top. most people think AI writes emails and makes pictures. meanwhile someone pointed it at one of the hardest physics problems on earth, held the plasma steady, and got paid by Elon Musk for it. the gap is not between humans and AI anymore. it is between the people who realize what this thing can already do and the people still using it to summarize their inbox.

Nuno F. Gomes Loureiro, who was a world-renowned MIT professor and fusion-energy physicist, was shot and killed inside his home earlier this week and now they're saying he was murdered by the Brown University shooter, who was found conveniently suicided. He just so happened to be an expert in several fundamental aspects of magnetized plasma dynamics, such as magnetic reconnection, magnetic field generation and amplification, confinement and transport in fusion plasmas, and turbulence in strongly magnetized, weakly collisional plasma fields. We've seen this COUNTLESS times throughout history - Assassinations hidden inside Mass Casualty Events, similar to the Titanic scenerio regarding Nikola Tesla's largest donor who was aboard the ship when it was sunk by Big Bankers fighting to enslave us all. Cabal assets generally stopped murdering people like this out in the open who were inventing clean energy solutions, since the birth of the internet caused too many wet-works to become mass publicized for exposure. Now they hide these asassinations inside Mass Casualty Events and hope no one notices. We notice. This exact scenerio happened just a few years ago too with Aaron Salter. Stanley Meyer also created a torodial hydrogen fuel cell engine that magnetically shredded water to strip oxygen from the hydrogen & use that hydrogen as fuel. They murdered him in 1998. Metaphysics - ignored, dismissed and lied about by mainstream $cience - is the most fascinating and second most important subject for humanity to learn, behind the Bible.
