US companies help build 60-foot-tall magnet that could revolutionize energy: 'A major engineering challenge'
Eight suppliers from six states have contributed to an astounding 60-foot-tall superconducting magnet crucial to a fusion experiment in France, according to the Oak Ridge National Laboratory, the agency overseeing the project. U.S. ITER shipped the unit for the central solenoid early this year. It's made of more than 9,000 parts that were developed during a decade of work by numerous companies. It joined other high-tech components at the International Thermonuclear Experimental Reactor, commonly called ITER, in Europe. The machine reportedly cost more than $22 billion, per Euronews. "Designing and manufacturing the first-of-a kind superconducting central solenoid is a major engineering challenge," Oak Ridge senior project engineer David Vandergriff said in a news release. ITER is being built as part of a seven-nation partnership to prove that fusion reactions can be sustained at scale, harnessing the same energy source that powers the sun. The goal is to maintain a reaction for hundreds of seconds, per Oak Ridge. Fission reactions already power 54 plants in the U.S. that produce about 19% of America's electricity, according to government data. But the atom-splitting process results in long-lasting nuclear waste. The byproduct is in the form of ceramic pellets, not green ooze, which is a common misconception. Rare, yet disastrous nuclear accidents are also a risk. Fusion reactions, in comparison, slam atoms together to form a new one, producing energy without lingering radioactive waste. The hurdle has been creating a chamber that produces more power than it takes to make it, per the U.S. Department of Energy. Both forms eliminate heat-trapping air pollution caused by the burning of dirty fossil fuels that increases the risk of severe weather, according to NASA. The extreme storms can cause blackouts, heat waves, and even higher insurance premiums. But activists such as Jane Fonda have been outspoken against efforts to expand fission projects, including the reopening of Three Mile Island in Pennsylvania. The site of an accident decades ago, it's now being tabbed by Microsoft to help power growing data center demand. Colorado-based clean energy think tank RMI co-founder Amory Lovins told The Cool Down that nuclear power is increasingly expensive and slow to develop, touting solar and wind as better options. Abundant, cleaner fusion energy could provide a game-changing answer to fission's problems with the potential to lower utility bills. And it will likely take a worldwide effort to unlock. Experiments are happening in China and elsewhere, as well. U.S. ITER's contribution is crucial to producing the magnetic flux needed to generate and maintain plasma current, according to Oak Ridge. Should we be digging into the ground to find new energy sources? Definitely No way As long as it's not near me As long as it's clean energy Click your choice to see results and speak your mind. The setup must be able to withstand massive force, which is partly why the reactions that involve swirling plasma in an environment heated to hundreds of millions of degrees are so tough to accommodate. The team developed strong support components to bolster the unit during the operational rigors. "At key times, the resultant vertical force on the module stack is up to 60 meganewtons — more than twice the force of a space rocket at blast off," U.S. ITER engineering technical director Kevin Freudenberg said in the release. There are also ways other than fusion to tap sun-related energy. Solar panels capture radiation directly from the sun, converting it to electricity with improved efficiency. You can reduce or eliminate your utility bill with the right setup. EnergySage is a free online tool that can help you leverage available tax breaks and find the best installer, resulting in thousands in savings with cleaner electricity. Palmetto's LightReach is a leasing option that can help you realize solar's cost savings without the upfront expenses, making the tech available to more people.

Every fusion startup that has raised over $100M
Over the last several years, fusion power has gone from the butt of jokes — always a decade away! — to an increasingly tangible and tantalizing technology that has drawn investors off the sidelines. The technology may be challenging to master and expensive to build today, but fusion promises to harness the nuclear reaction that powers the sun to generate nearly limitless energy here on Earth. If startups are able to complete commercially viable fusion power plants, then they have the potential to upend trillion-dollar markets. The bullish wave buoying the fusion industry has been driven by three advances: more powerful computer chips, more sophisticated AI, and powerful high-temperature superconducting magnets. Together, they have helped deliver more sophisticated reactor designs, better simulations, and more complex control schemes. It doesn't hurt that, at the end of 2022, a U.S. Department of Energy lab announced that it had produced a controlled fusion reaction that produced more power than the lasers had imparted to the fuel pellet. The experiment had crossed what's known as scientific breakeven, and while it's still a long ways from commercial breakeven, where the reaction produces more than the entire facility consumes, it was a long-awaited step that proved the underlying science was sound. Founders have built on that momentum in recent years, pushing the private fusion industry forward at a rapid pace. Commonwealth Fusion Systems With a $1.8 billion Series B, Commonwealth Fusion Systems catapulted itself into the pole position in 2021. Since then, the company has been quiet on the fundraising front (no surprise), but it has been hard at work in Massachusetts building Sparc, its first-of-a-kind power plant intended to produce power at what it calls 'commercially relevant' levels. Sparc's reactor uses a tokamak design, which resembles a doughnut. The D-shaped cross section is wound with high-temperature superconducting tape, which when energized, generates a powerful magnetic field that will contain and compress the superheated plasma. In Sparc's successor, the commercial-scale Arc, heat generated from the reaction is converted to steam to power a turbine. CFS designed its magnets in collaboration with MIT, where co-founder and CEO Bob Mumgaard worked as a researcher on fusion reactor designs and high-temperature superconductors.

Join visionaries from Precursor Ventures, NEA, Index Ventures, Underscore VC, and beyond for a day packed with strategies, workshops, and meaningful connections. Boston, MA | REGISTER NOW Backed by Breakthrough Energy Ventures, The Engine, Bill Gates, and others, Devens, Massachusetts-based CFS expects to have Arc operational in the early 2030s. The company has raised a total of $2 billion, according to PitchBook. TAE Founded in 1998, TAE Technologies (formerly known as Tri Alpha Energy) was spun out of the University of California, Irvine by Norman Rostoker. It uses a field-reversed configuration, but with a twist: after the two plasma shots collide in the middle of the reactor, the company bombards the plasma with particle beams to keep it spinning in a cigar shape. That improves the stability of the plasma, allowing more time for fusion to occur and for more heat to be extracted to spin a turbine. The company raised $150 million in June from existing investors, including Google, Chevron, and New Enterprise. TAE has raised $1.79 billion in total, according to PitchBook. Helion Of all fusion startups, Helion has the most aggressive timeline. The company plans to produce electricity from its reactor in 2028. Its first customer? Microsoft. Helion, based in Everett, Washington, uses a type of reactor called a field-reversed configuration, where magnets surround a reaction chamber that looks like an hourglass with a bulge at the point where the two sides come together. At each end of the hourglass, they spin the plasma into doughnut shapes that are shot toward each other at more than 1 million mph. When they collide in the middle, additional magnets help induce fusion. When fusion occurs, it boosts the plasma's own magnetic field, which induces an electrical current inside the reactor's magnetic coils. That electricity is then harvested directly from the machine. The company raised $425 million in January 2025, around the same time that it turned on Polaris, a prototype reactor. Helion has raised $1.03 billion, according to PitchBook. Investors include Sam Altman, Reid Hoffman, KKR, BlackRock, Peter Thiel's Mithril Capital Management, and Capricorn Investment Group. Pacific Fusion Pacific Fusion burst out of the gate with a $900 million Series A, a whopping sum even among well-funded fusion startups. The company will use inertial confinement to achieve fusion, but instead of lasers compressing the fuel, it will use coordinated electromagnetic pulses. The trick is in the timing: All 156 impedance-matched Marx generators need to produce 2 terawatts for 100 nanoseconds, and those pulses need to simultaneously converge on the target. The company is led by CEO Eric Lander, the scientist who led the Human Genome Project, and president Will Regan. Pacific Fusion's funding might be massive, but the startup hasn't gotten it all at once. Rather, its investors will pay out in tranches when the company achieves specified milestones, an approach that's common in biotech. Shine Technologies Shine Technologies is taking a cautious — and possibly pragmatic — approach to generating fusion power. Selling electrons from a fusion power plant is years off, so instead, it's starting by selling neutron testing and medical isotopes. More recently, it has been developing a way to recycle radioactive waste. Shine hasn't picked an approach for a future fusion reactor, instead saying that it's developing necessary skills for when that time comes. The company has raised a total of $778 million, according to PitchBook. Investors include Energy Ventures Group, Koch Disruptive Technologies, Nucleation Capital, and the Wisconsin Alumni Research Foundation. General Fusion Now its third-decade, General Fusion has raised $440.53 million, according to PitchBook. The Richmond, British Columbia-based company was founded in 2002 by physicist Michel Laberge, who wanted to prove a different approach to fusion known as magnetized target fusion (MTF). Investors include Jeff Bezos, Temasek, BDC Capital, and Chrysalix Venture Capital. In an General Fusion's reactor, a liquid metal wall surrounds a chamber in which plasma is injected. Pistons surrounding the wall push it inward, compressing the plasma inside and sparking a fusion reaction. The resulting neutrons heat the liquid metal, which can be circulated through a heat exchanger to generate steam to spin a turbine. General Fusion hit a rough patch in spring 2025. The company ran short of cash as it was building LM26, its latest device that it hoped would hit breakeven in 2026. Just days after hitting a key milestone, it laid off 25% of its staff. Tokamak Energy Tokamak Energy takes the usual tokamak design — the doughnut shape — and squeezes it, reducing its aspect ratio to the point where the outer bounds start resembling a sphere. Like many other tokamak-based startups, the company uses high-temperature superconducting magnets (of the rare earth barium copper oxide, or REBCO, variety). Since its design is more compact than a traditional tokamak, it requires less in the way of magnets, which should reduce costs. The Oxfordshire, UK-based startup's ST40 prototype, which looks like a large, steampunk Fabergé egg, generated an ultra-hot, 100 million degree C plasma in 2022. Its next generation, Demo 4, is currently under construction and is intended to test the company's magnets in 'fusion power plant-relevant scenarios.' Tokamak Energy raised $125 million in November 2024 to continue its reactor design efforts and expand its magnet business. In total, the company has raised $336 million from investors including Future Planet Capital, In-Q-Tel, Midven, and Capri-Sun founder Hans-Peter Wild, according to PitchBook. Zap Energy Zap Energy isn't using high-temperature superconducting magnets or super-powerful lasers to keep its plasma confined. Rather, it zaps the plasma (get it?) with an electric current, which then generates its own magnetic field. The magnetic field compresses the plasma about 1 millimeter, at which point ignition occurs. The neutrons released by the fusion reaction bombard a liquid metal blanket that surrounds the reactor, heating it up. The liquid metal is then cycled through a heat exchanger, where it produces steam to drive a turbine. Like Helion, Zap Energy is based in Everett, Washington, and the company has raised $327 million, according to PitchBook. Backers include Bill Gates' Breakthrough Energy Ventures, DCVC, Lowercarbon, Energy Impact Partners, Chevron Technology Ventures, and Bill Gates as an angel. Proxima Fusion Most investors have favored large startups that are pursuing tokamak designs or some flavor of inertial confinement. But stellarators have shown great promise in scientific experiments, including the Wendelstein 7-X reactor in Germany. Proxima Fusion is bucking the trend, though, having attracted a €130 million Series A that brings its total raised to more than €185 million. Investors include Balderton Capital and Cherry Ventures. Stellarators are similar to tokamaks in that they confine plasma in a ring-like shape using powerful magnets. But they do it with a twist — literally. Rather than force plasma into a human-designed ring, stellarators twist and bulge to accommodate the plasma's quirks. The result should be a plasma that remains stable for longer, increasing the chances of fusion reactions. Marvel Fusion Marvel Fusion follows the inertial confinement approach, the same basic technique that the National Ignition Facility used to prove that controlled nuclear fusion reactions could produce more power than was needed to kick them off. Marvel fires powerful lasers at a target embedded with silicon nanostructures that cascade under the bombardment, compressing the fuel to the point of ignition. Because the target is made using silicon, it should be relatively simple to manufacture, leaning on the semiconductor manufacturing industry's decades of experience. The inertial confinement fusion startup is building a demonstration facility in collaboration with Colorado State University, which it expects to have operational by 2027. Munich-based Marvel has raised a total of $161 million from investors including b2venture, Deutsche Telekom, Earlybird, HV Capital, and Taavet Hinrikus and Albert Wenger as angels. First Light First Light dropped its pursuit of fusion power in March 2025, pivoting instead to become a technology supplier to fusion startups and other companies. The startup had previously followed an approach known as inertial confinement, in which fusion fuel pellets are compressed until they ignite. First Light, which is based in Oxfordshire, U.K., has raised $140 million, according to PitchBook, from investors including Invesco, IP Group, and Tencent. Xcimer Though nothing about fusion can be described as simple, Xcimer takes a relatively straightforward approach: follow the basic science that's behind the National Ignition Facility's breakthrough net-positive experiment, and redesign the technology that underpins it from the ground up. The Colorado-based startup is aiming for a 10-megajoule laser system, five times more powerful than NIF's setup that made history. Molten salt walls surround the reaction chamber, absorbing heat and protecting the first solid wall from damage. Founded in January 2022, Xcimer has already raised $109 million, according to PitchBook, from investors including Hedosophia, Breakthrough Energy Ventures, Emerson Collective, Gigascale Capital, and Lowercarbon Capital.

Proxima will also finalize a site for Alpha, its demonstration stellarator, for which it is in talks with several European governments already. Alpha is scheduled to begin operations in 2031, and is the key step to demonstrating Q>1 (net energy gain) and moving towards a first-of-a-kind fusion power plant. The company will continue to grow its 80+-strong team across three offices: at the headquarters in Munich, at the Paul Scherrer Institute near Zurich (Switzerland), and at the Culham fusion campus near Oxford (UK). "Fusion energy is entering a new era—moving from lab-based science to industrial-scale engineering," said Dr. Francesco Sciortino. "This investment validates our approach and gives us the resources to deliver hardware that is essential to make clean fusion power a reality." Ian Hogarth, Partner at Plural said: "Proxima Fusion exemplifies a new kind of European ambition - a full force effort to develop the world's first fusion power plant. Since their first round of funding two years ago, Francesco and the team have hit extremely challenging milestones ahead of schedule and hired a team that spans plasma physics, advanced magnet design and computer simulation. Their peer-reviewed stellarator power plant design concept confirms that fusion really can be commercially viable, and creates an opportunity for Europe to be first to the target."

'Fusion Reactors Were About to Explode': This Insane X-Point Radiator Hack Is Saving the Planet in Real Time
IN A NUTSHELL 🔥 Swiss researchers have developed an innovative method to prevent tokamak reactors from overheating, enhancing efficiency. have developed an innovative method to prevent tokamak reactors from overheating, enhancing efficiency. 🔬 The discovery, known as the X-point target radiator (XPTR) , effectively dissipates excess heat in fusion reactors. , effectively dissipates excess heat in fusion reactors. 🌀 By introducing a secondary X-point, the design optimizes heat radiation and maintains plasma stability in the reactor. 🔋 This advancement brings the dream of clean fusion energy closer to reality, potentially transforming future power generation. Swiss researchers at the École Polytechnique Fédérale de Lausanne (EPFL) have made an exciting breakthrough that could revolutionize the future of energy production. They have discovered a novel way to prevent tokamak fusion reactors from overheating, thereby making them more efficient and reliable. This advancement, known as the X-point target radiator (XPTR), not only controls excess heat but also promises to improve reactor performance over time. With the potential to solve one of fusion's most significant challenges, this discovery might be a pivotal step towards achieving sustainable and clean energy through nuclear fusion. Understanding the Tokamak Reactor Tokamak reactors represent one of the most promising avenues for achieving nuclear fusion on Earth, a process that mimics the energy production of the Sun. These reactors utilize powerful magnetic fields, arranged in a doughnut shape, to contain and heat a gas known as plasma. As this plasma becomes exceedingly hot, it behaves like an electrically charged fluid, setting the stage for nuclear fusion to occur. The fusion process generates immense heat, some of which escapes and impacts the reactor's internal surfaces, particularly in an area called the divertor. The divertor is crucial because it channels away excess plasma and heat, preventing damage to the reactor. However, the continuous heat exposure poses a significant challenge, as it can degrade the reactor's components over time. The EPFL team's innovative approach to reducing the heat load on a tokamak's inner walls could address this issue effectively. By introducing a secondary X-point further down the divertor channel, their design aims to dissipate heat more evenly and enhance the reactor's operational stability and longevity. 'Airplanes Are the New Wind Farms': This Astonishing Breakthrough Turns Jet Turbine Gusts Into Tomorrow's Green Energy Revolution Fusion: The Energy Holy Grail Nuclear fusion is often heralded as the holy grail of energy due to its potential to provide a virtually limitless, clean source of electricity. Unlike traditional nuclear power, which relies on fission and generates radioactive waste, fusion merges light atoms like hydrogen to form a heavier one, such as helium, releasing massive energy without harmful emissions. Scientists have long sought to harness this reaction on Earth, with tokamak reactors being a leading contender in this quest. However, achieving controlled fusion is fraught with challenges, primarily due to the intense heat generated during the process. This heat, if not managed properly, can damage reactor components, making sustained fusion reactions difficult to maintain. The EPFL team's discovery of the XPTR could be a game-changer, offering a viable solution to controlling and utilizing this heat effectively. By reducing the heat load on critical reactor areas, the XPTR makes the dream of practical fusion energy more attainable. 'China Risks $117 Billion Collapse': This Scientist's Rare-Earth-Free Super Magnet Could Wreck an Entire National Industry Cooler, More Efficient Tokamaks The introduction of a secondary X-point in the tokamak design is a significant advancement in fusion technology. This additional X-point allows heat to be radiated away more uniformly, reducing damage to the reactor's vulnerable parts while maintaining plasma stability. Importantly, this design does not interfere with the central plasma, which is essential for sustained fusion reactions. The innovation also proves versatile, functioning across a wide range of conditions and adding to its reliability and scalability. MIT and Commonwealth Fusion Systems plan to incorporate this design into SPARC, their upcoming major fusion project. Ongoing experiments and simulations aim to refine this technology further, preparing it for application in future power plants. The XPTR's ability to manage heat safely without compromising the reactor's integrity addresses one of the most significant obstacles to fusion energy, inching closer to making fusion a practical energy solution. 'U.S. Delivers a Monster': 60-Foot Superconducting Magnet Sent to France to Power the Heart of the ITER Fusion Reactor The Path Forward: Challenges and Opportunities While the discovery of the XPTR marks a significant milestone in fusion research, several challenges remain. Engineering a reactor that can sustain fusion reactions over extended periods requires meticulous design and innovation. The scalability of the XPTR and its integration into existing and future reactor designs will be critical in determining its success. Additionally, ongoing research and development will be necessary to adapt this technology to various reactor configurations and operational conditions. Nonetheless, the potential benefits of mastering fusion energy are immense. By providing a clean, sustainable, and virtually limitless energy source, fusion could play a crucial role in combating climate change and reducing reliance on fossil fuels. As researchers continue to refine these technologies, the question remains: how soon can we expect to see fusion energy become a staple of our power grid, transforming the way we generate and consume energy?
