Nuclear fusion originates in our sun and other stars. Immense pressure and high temperatures in the core create a reaction, ultimately preventing it from collapsing under the force of gravity. "The ...

For decades, the dream of a virtually limitless, clean energy source has hovered just out of reach, more science fiction than reality. Now, a new “volume burn” breakthrough in nuclear fusion research ...

Energy is not great for peace. Countries go to war over fossil fuels, argue over nuclear power and commit some of the worst atrocities of human slavery to mine the materials we need to power our world ...

Workers wear protective equipment in a cavernous hall that contains industrial equipment. The tokamak hall at Commonwealth Fusion Systems’ fusion energy facility in Devens, Massachusetts, will house ...

Net power through nuclear fusion, a long dreamed-of goal, may finally be within reach. Fusion technology is moving out of the lab and many companies, including recently-founded ones, are striving to ...

Nuclear fusion research has achieved net positive energy, but it is still a net energy drain due to the high energy cost of the laser. Cost is the main obstacle to commercializing nuclear fusion, and ...

Helion Energy wants to produce large amounts of electricity through fusion by 2028. Microsoft has agreed to buy 50 megawatts of electricity from Helion, which can power 40,000 homes. Helion's chief ...
