Ultra-hot, superconducting magnets to enable fusion power.
Fusion, the power of the stars, is the holy grail of clean energy: limitless, dispatchable, concentrated, and carbon-free. Unlike convention 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 breakeven—where the reactor gives off more energy than it takes in—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 where these reactions occur are extremely difficult to sustain. Whereas some other efforts seek to produce the conditions for fusion by building bigger magnets, CFS is making far more powerful ones that will confine this star-like plasma and harness its power.
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.
