British Fusion Startup Pursues New Approach

The UK company First Light Fusion has published a plan for a new nuclear fusion concept called FLARE. It’s a two-step approach to inertial confinement. First, they want to squeeze the fuel slowly with an electrical pulse, then ignite it quickly with a small burst – for example, a short laser pulse. All this happens in a big pool of liquid lithium that soaks up heat, generates power, and also breeds tritium as a new fuel.

They say the gain (meaning energy from fusion divided by energy delivered to the fuel) could reach a stunning 200 to 1,000. About the timeline, they vaguely say they hope to have a “commercial demonstration potentially by the mid-thirties.” First Light Fusion has previously used solid projectiles to shoot at fuel targets and was aiming at commercialisation in the early 2030s.

The full concept plan is available here: https://t.co/EAs67ghbZB

First Light Fusion has presented what it says is the first commercially viable, reactor-compatible path to 'high gain' fusion, which it says would drastically reduce the cost of what the company says is a limitless clean energy source.
