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

Elon Musk just exposed the most catastrophic energy blindspot in the entire AI arms race. The West is still debating which twigs to burn. China is capturing the sun. Musk: “People just don’t understand how solar is everything. Compared to the sun, all other energy sources are like cavemen throwing some twigs into a fire.” Every natural gas plant. Every nuclear reactor. Every experimental fusion project being debated in Washington right now. Twigs. Musk: “We have a giant free fusion reactor that shows up every day. It’s farcical for us to create little fusion reactors.” And then he gave the most clarifying statistic in the entire energy debate. Musk: “The sun is over 99.8% of all mass in the solar system. Jupiter is around 0.1%. So even if you burnt Jupiter, the energy produced by the sun would still round up to 100%.” Musk: “And then if you teleported three more Jupiters into our solar system and burnt them too, it would still round up.” The sun is not an energy source. It is the only energy source. Everything else is rounding error. China already knows this. While American tech executives beg for permits to build natural gas plants, China crossed 1,000 gigawatts of installed solar capacity in 2025. More than the rest of the world combined. They are not holding summits about it. They are not commissioning reports about it. They are building it. Harvesting the free fusion reactor that arrives every morning at zero cost and feeding it directly into their AI data centers. The AI race is not an algorithm race. It is an electro-industrial race. You cannot build superintelligence without infinite compute. You cannot have infinite compute without infinite energy. And right now, the United States is losing the energy war while holding committee meetings about which twigs to burn next. China built the energy-compute flywheel. Cheap, scalable, infinite solar power feeding AI models at a fraction of the cost. Compounding every single day. The nation that captures the sun’s output will hold a permanent monopoly on global intelligence. The nation that doesn’t will spend the next decade trying to understand how it lost. Everyone else gets left holding the twigs.
