Slashing CO2Plasma-taming fusion magnets.
Big Picture
Fusion, the power of the stars, is the holy grail of clean energy: limitless, dispatchable, concentrated, and carbon-free. Unlike conventional nuclear, there is inherently no risk of meltdown, proliferation, or waste. Since the dawn of the nuclear age, scientists have sought to harness fusion, yet achieving net energy gain—where the reactor puts out more energy than it needs to run it—has proven elusive.
How It Works
Fission splits atoms, whereas fusion joins them. However, the immense pressure and energy needed to generate a 100m°C plasma – superheated matter composed of atoms so hot, they’ve lost their electrons – for fusion to occur is extremely difficult to sustain. While others seek to make bigger magnets, CFS has made the most powerful magnets, that can confine plasma long enough to harness its power.
Unfair Advantage
What gives CFS the surest path to commercial fusion is the combination of proven tokamak physics with breakthrough magnet technology. They have developed new, high-temperature superconducting tape to build the world’s most powerful magnets. This enables 60x smaller, more affordable reactors that accelerate the path to commercial fusion energy in time and on a scale to make a difference.
