First Light Fusion

Solving fusion power with the simplest means possible - powering a world worth inheriting

First Light Fusion is the world's leading inertial fusion company. Inertial fusion has been proven to achieve gain (more power out than in) using laser technology at the National Ignition Facility - the physics works. Projectile fusion is a new approach to inertial fusion that is simpler, more energy efficient, and has lower physics risk. Inertial fusion is a pulsed process, where, like an internal combustion engine, a small amount of fuel is injected and sparked to make it burn. The main existing approach to inertial fusion uses a large laser as the "spark plug", triggering the reaction. We use a high velocity projectile and amplifier technology instead. Our in-house simulations allow us to simulate experiments before using our pulsed power machines to test them, which has allowed speed. We continue to successfully demonstrate fusion while we develop the amplifier technology.
