US tool to recreate deep-earth conditions to unlock 'superhot' power
Oregon State University (OSU) has received a $750,000 donation from Quaise Energy to advance research on superhot rock (SHR) geothermal energy, a promising resource estimated to have the potential to generate 63 terawatts of power—over eight times the current global electricity output—by exploiting just 1% of SHR resources located 2 to 12 miles beneath the Earth's surface. The funding supports OSU’s Experimental Deep Geothermal Energy (EDGE) lab in simulating extreme deep-earth conditions, specifically studying water at supercritical temperatures (374°C) and pressures (up to 500 atmospheres), where water can transport up to five times more energy than standard hot water. This research is crucial as existing geothermal models do not accurately predict behaviors in such superhot regimes. The EDGE lab, led by Assistant Professor Brian Tattitch, uses a custom flow-through reactor to observe real-time chemical interactions between rock and fluids under these conditions, aiming to overcome challenges such as mineral

Aiden MacMillan, a 12-year-old seventh grader from Dallas, claims to have built a nuclear fusion reactor at a makerspace called Launchpad, where he developed prototypes over two years. His device reportedly generated neutrons, indicating that fusion occurred, making him potentially the youngest person to achieve this feat. MacMillan’s interest in fusion began during the COVID-19 lockdowns, driven by his belief that fusion is the future of energy. He now aims to break the Guinness World Record previously held by Jackson Oswalt, who built a fusion reactor at age 12 in 2020. While MacMillan’s accomplishment is impressive for his age and dedication, experts emphasize that such achievements do not advance nuclear fusion science in a practical sense. The main challenge in fusion energy research lies in creating a commercially viable process that can generate large-scale, cost-competitive power. Current efforts by research institutes and startups focus on making fusion energy a feasible alternative to fossil fuels and renewable sources like wind and solar.

Engineers at the U.S. Department of Energy’s Argonne National Laboratory are proactively testing how insider threats could compromise passive safety systems in next-generation nuclear reactors before these designs are finalized and licensed. Passive safety systems, which rely on natural physical processes rather than active controls, are widely used and trusted in current reactors, but future designs like small modular reactors depend even more heavily on them. Argonne’s research focuses on realistic sabotage scenarios involving insiders with authorized access, such as leaving access points open or blocking cooling pathways, to identify vulnerabilities that could cause system failures. Using the Natural Convection Shutdown Heat Removal Test Facility, Argonne and collaborating national labs have simulated these sabotage scenarios to observe system responses under stress. Their findings, compiled in a report for the International Atomic Energy Agency, confirm that while multiple layers of protection—such as controlled access, alarms, and redundancy—make successful sabotage difficult, some vulnerabilities remain and should be addressed early in the design process. The goal is to guide reactor developers in strengthening

The Tennessee Valley Authority’s Bull Run Energy Complex in Tennessee is preparing to host a new high-heat flux (HHF) testing facility, a collaborative project involving the Department of Energy’s Oak Ridge National Laboratory (ORNL), Type One Energy, and the University of Tennessee, Knoxville (UT). Scheduled for completion by the end of 2027, the facility will simulate the extreme heat flux conditions found in fusion reactors—targeting steady-state heat loads exceeding 10 megawatts per square meter—to test plasma-facing components (PFCs) that must endure intense operational stresses. This will be the second such facility in the U.S. and the most powerful, uniquely featuring pressurized helium gas cooling, which is favored in several domestic fusion reactor designs due to helium’s chemical stability under fusion conditions. The Bull Run site, already home to Type One Energy’s Infinity One stellarator testbed, is envisioned as a fusion development campus integrating research from ORNL, UT, and industry partners. ORNL

Researchers at Japan’s National Institute for Fusion Science (NIFS) have solved a longstanding puzzle in fusion reactor physics regarding the rapid heat loss from the plasma core to the edge, which occurs much faster than conventional diffusion theory predicts. Using the Large Helical Device (LHD), the team discovered that plasma turbulence operates in two modes: a slow, local “running game” and a fast, long-range “passing game.” The latter, described as a mediator turbulence, enables heat to leap across distant regions of the reactor almost instantly—within a ten-thousandth of a second—bypassing the space in between and undermining magnetic confinement. To capture this rapid phenomenon, the researchers applied short, intense heating pulses and employed high-precision diagnostics capable of microsecond resolution. Their data confirmed that shorter heating pulses amplify the mediator turbulence, accelerating heat loss. This insight transforms the understanding of plasma turbulence from a chaotic process to a complex system with dual roles in heat transport. Crucially, identifying this mediator

A team of researchers from Lawrence Berkeley National Laboratory and the University of California, Berkeley, has successfully simulated a next-generation quantum microchip using nearly 7,200 NVIDIA GPUs on the Perlmutter supercomputer at the National Energy Research Scientific Computing Center. This full-scale physical simulation, conducted over 24 hours, represents a significant advancement in quantum hardware design by enabling scientists to predict chip performance, identify potential issues, and reduce errors before fabrication. The simulation utilized the exascale modeling tool ARTEMIS to capture detailed electromagnetic wave propagation and interactions within the chip, which measures just 10 millimeters square and 0.3 millimeters thick with micron-scale features. The simulation was unprecedented in scale and complexity, discretizing the chip into 11 billion grid cells and running over a million time steps in seven hours, allowing testing of multiple circuit configurations daily. Unlike typical simulations, this approach modeled the chip’s material composition, wiring, resonator geometry, and electromagnetic interactions in full-wave physical detail, including

UK-based fusion company Tokamak Energy has unveiled the first high-speed color footage capturing plasma behavior inside its ST40 spherical tokamak, marking a significant advancement in visualizing fusion processes. Using a camera that records at 16,000 frames per second, researchers observed how deuterium gas fuels the plasma, visible as a bright pink glow, and how lithium granules interact with the plasma. The lithium initially emits a crimson-red light in the cooler outer plasma regions and then glows greenish-yellow as it ionizes in the hotter core, tracing magnetic field lines that confine the plasma. This visual data complements spectroscopy measurements and enhances understanding of plasma fueling and control at temperatures of tens of millions of degrees. These experiments are part of a $52 million upgrade program called LEAPS (Lithium Evaporations to Advance PFCs in ST40), conducted in partnership with the US Department of Energy and the UK’s Department for Energy Security and Net Zero.

A recent study led by researchers from the National Renewable Energy Laboratory (NREL) and collaborators worldwide has revealed that hybrid plasmon-polaritons (HPPs)—waves formed by the coupling of plasmons and light—can persist for an exceptionally long time in strongly correlated materials known as "bad" metals. These materials, characterized by intense electron interactions and incoherent electron motion, were previously thought to be unfavorable for sustaining such collective charge waves. The team focused on molybdenum dichloride dioxide (MoOCl2), a bad metal where electron behavior is chaotic, and discovered that HPPs remain stable and propagate effectively even at room temperature, surviving for up to 10 oscillation cycles—longer than in any known crystal. This finding challenges conventional understanding by demonstrating that coherent plasmonic excitations can exist in systems with high resistance and electron incoherence. The research utilized advanced imaging techniques and theoretical models to explain the dielectric response responsible for plasmon creation and longevity. Unlike
