Energy is the lever that moves the world.

Achieving humanity’s potential requires generating more energy, not less. But today’s energy sources are holding us back.

Our mission is to free humanity from fossil fuels, save the planet from climate change and unlock a new era of progress, prosperity and safety for all.

Energy is the lever that moves the world.

We're harnessing clean, safe, and abundant energy from fusion to power the next generation of human progress.

Fossil fuels powered the industrial revolution, the space age, and much of what we now consider modern society. But they've also harmed people and the planet.

We believe a new source of abundant energy - without those externalities - will once again transform the course of human civilization. It will free us from our dependence on fossil fuels, and allow us to dream again about what humanity can achieve without limits, propelling us in ways we've yet to imagine.

THE CHANGE WE WANT TO DELIVER

Safe

Inertial fusion fuel requires precise control to ignite and burns only for a few billionths of a second. There is no chance of an uncontrolled or unexpected energy release.

  • Safe

    Each fuel capsule contains just a few milligrams of hydrogen fuel.

  • Safe

    Only one fuel capsule is in the chamber at a time, with no chance of accidental energy release.

Reliable

Fusion is always available and can run reliably 24/7, 365 days per year, regardless of weather, temperature, rainfall, or season. Fusion is a source of energy humanity can depend on.

  • Reliable
  • Reliable

Approximation based on Geophysical constraints on the reliability of solar and wind power worldwide

Abundant

The fuel for fusion comes from seawater and lithium, and humanity has enough of these to last for millions of years.

  • Abundant

    Chematall Foote lithium operation in Nevada has a current capacity of 14,500 tons per year

  • Abundant

    The oceans are an abundant resource for deriving hydrogen isotopes

Inexpensive

Xcimer inertial fusion will be economically competitive with fossil fuels and superior to renewables, enabling use cases we haven’t yet thought possible.

Inexpensive

Carbon-free

Inertial fusion is clean and does not release pollutants, including carbon.

  • Carbon-free

    Globally, fossil fuel plants emitted 36 billion tons of carbon in 2023

  • Carbon-free

    Inertial fusion will deliver power to the grid at zero carbon emissions

Unlimited

Per capita energy consumption in the United States stopped growing in the 1970s. Fusion will return us to the path of technological growth, progress and optimism that we were on before we learned of the damage fossil fuels were doing to the environment.
