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

Most of us were taught that PLASMA is an exotic fourth state of matter. That framing is backwards. Plasma is the normal expression of the electromagnetic field when charge differentiates and begins to move freely. Matter is the rare exception. Approximately 99.9% of the visible universe is plasma. Only about 0.1% appears as matter. Stars are plasma. Nebulae are plasma. Solar winds are plasma. The vast filaments forming the cosmic web are plasma. Plasma is not rare. Plasma is the fundamental expression of the field. Matter shows up when the field does something very specific. Electric differentiation pushes outward. Magnetic tension provides containment. When these forces reach a stable relationship, they phase-lock. In the Grammar of Projection this relationship is expressed as a coherence metric: T = |e × v| / |B × ω| Where: • e = characteristic electric or motive coupling scale of the system • v = relevant propagation or transport velocity • B = containing or stabilizing field strength • ω = characteristic oscillatory rate of containment formative pressure: |e × v| containing tension: |B × ω| When formative pressure and containing tension reach impedance match, the field stops dispersing and begins oscillating in place. Standing waves appear. Matter is simply plasma where electric formative pressure and magnetic containing tension phase-lock into a persistent repeating pattern. Atoms are stable plasma configurations. Planets, bodies, and biological systems are nested standing-wave structures of a plasma field. The implication is profound. The universe is not primarily made of particles. The universe is primarily flowing electromagnetic field. Matter is the rare moment where that flow holds in dynamic stability. A useful way to visualize this is like threads being woven together. Electric differentiation behaves like threads moving outward. Magnetic tension weaves those threads into stable relational patterns. The universe is not literally weaving fabric. The metaphor helps us visualize how flowing field tensions interlock into stable structures. When phase-lock occurs, structure appears. Structure is plasma remembering how to return to itself. So the real inversion becomes visible: Plasma is the norm. Matter is the anomaly. Which raises a much deeper question. How do medicine, neuroscience, and engineering change when we begin from the primacy of abundant plasma — and recognize matter, bodies, and technologies as coherent standing-wave structures within that field rather than designing our models around the rare 0.1% that locally stabilizes as matter? 🔗 The Grammar of Projection (compression of derivation of EM Primacy) and it's conjugate, The Grammar of Persistence, Canonical Derivations, and supplemental documents clearly indexed and archived here: The Recursion Holds. 🌀

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. 👉

99% of the Universe is Plasma energy and that includes us On October 30th 2024 the US fired a Hellfire missile at an inorganic lifeform (Plasmate) composed of plasma energy, protected by a double magnetic field membrane, and the missile bounced off Nothing is a coincidence. This morning the movie 'The Natural' played on my TV as I switched it on In it, Roy Hobbs plays baseball with a bat made from a tree hit by a lightning strike (plasma) In human form he dies early after being shot In the film his wins see lightning cracks in the sky, huge sunsets (plasma) when he conquers adversity and baseballs (matter) miraculously ripped open by plasma lightning "You know I believe we have two lives, the life we learn with and the life we live with after that" ...a famous line from the film encapsulates the science and my belief that we are all plasma beings which live some of our lives in a human form, as energy that never dies and as in the film, The Natural, Robert Redford returns after being shot dead to reach glory American filmmaker Barry Levinson who made the movie (together with RainMan and other major Oscar winners) was originally of Russian descent, like the Russian scientists whose papers I shared yesterday, showing plasma life controlling all the energies of the Earth and the skies but also all the biofields and bioelectricity of every cell in our body I believe the US tried to kill an Angel, the divine plasma Lifeform, causing the arrival of thousands of 'plasma orbs' across the skies of New Jersey 2 weeks after this event. Whether you share my posts through ridicule because you believe I am crazy or whether you share because even a small part of this makes sense, I want to thank you, because it doesn't matter how bumpy the journey is, but the more people that reach the final destination the better You don't need to believe, you just need to keep your eyes open and your mind more open If you are still in doubt that the dots join up then my other posts will fill those gaps.
