Seattle startup Avalanche Energy has raised new funding to develop its compact fusion energy devices. A filing puts the ...

Scientists developing a compact version of a nuclear fusion reactor have shown in a series of research papers that it should work, renewing hopes that the long-elusive goal of mimicking the way the ...

A France-based company is using stellarator technology to accelerate fusion research in Europe. Renaissance Fusion is building stellarators that it claims could be the most efficient, steady, and ...

For seventy years, one stubborn physics problem has stood between fusion’s promise and practical reactors. That puzzle, how ...

Scientists at the DIII-D National Fusion Facility have released a new design for a compact fusion reactor that can generate electricity and help define the technology necessary for commercial fusion ...

First tokamak plasma at the SMall Aspect Ratio Tokamak – SMART – recorded with a fast-framing camera in the visible spectral range. In a pioneering approach to achieve fusion energy, the SMART device ...

The Navy just patented a major potential breakthrough on compact fusion reactors, but the patent is long on claims and short on implementation specifics. Share on Facebook (opens in a new window) ...

The X-point radiator emits not only UV light but also visible blue light in a ring-shaped area above the divertor. The left picture shows a camera image (below the normal red glow of the cold plasma ...

Research done by nT-Tao and Ben-Gurion University of the Negev introduces a new “nonlinear controller” that keeps power flowing smoothly even as the plasma inside the reactor changes rapidly. Israeli ...

For decades, nuclear fusion has been viewed as the ultimate energy source—clean, powerful, and practically limitless. Most approaches to fusion involve enormous machines designed to squeeze plasma ...

Startup company Tokamak Energy has published three papers showing size is not an important factor in fusion reactors and proving that a compact spherical tokamak reactor can produce high power. This ...

A team of researchers at MIT and other institutions say their “SPARC” compact fusion reactor should actually work — at least in theory, as they argue in a series of recently released research papers.
