Handheld fusion reactors.

Big Picture

Fusion has always aimed big: mammoth reactors, colossal construction, and behemoth budgets. The physics of most confinement schemes demand large scales. Yet, if you could pull it off, small reactors would enable rapid R&D iteration and mass manufacturing. If reactors could scale down far enough, fusion might one day power our planes, ships, and trucks with safe, carbon-free, virtually inexhaustible energy. 

How It Works

Avalanche’s modular reactors combine de-risked and already commercialized technologies in novel ways to produce proton-boron fusion. The devices will stack like battery packs, enabling fusion power that scales up to megawatts and down to kilowatts. The size enables rapid build, test, and iterate cycles, as well as high-speed, high-volume production lines using conventional manufacturing techniques.

Unfair Advantage

This approach to fusion is so far outside the conventionally recognized paths to plasma confinement because it was developed by rocket scientists with no business working in plasma physics. The reactor measures about the size of a microwave, a form factor that could unlock decarbonization of some of the hardest-to-clean sectors of the global economy, from aviation and maritime to truck freight and off-grid power.
