Pacific Fusion

Pacific Fusion is developing high-gain pulsed magnetic fusion technology to produce clean energy. The company's approach involves using fast-rising, high-current pulses to magnetically squeeze and heat small containers of deuterium-tritium fuel to achieve fusion conditions. Pacific Fusion's technology builds on inertial fusion concepts demonstrated at US National Laboratories. The company's system consists of three main components: pulser modules, a meter-scale fusion chamber, and centimeter-scale fuel containers. The pulser modules store electricity in capacitors and release it in fast pulses through metallic tubes that implode towards the fusion chamber, where energy from multiple transmission lines is coupled into electrodes to compress the target and cause fusion.

The company's design uses mass-manufacturable units called "bricks", each containing two capacitors and a switch, which are assembled into modules that fit into shipping containers. The fusion chamber is compact and cylindrical, allowing for low-cost maintenance and the use of widely available materials. Pacific Fusion aims to achieve a 'net facility gain' - producing more fusion energy output than the total stored energy input. The company claims its fuel costs will be lower than fossil fuels, even taking into account consumables such as fuel containers. 

As of November 2024, the company was yet to commercialize its pulse magnetic fusion technology.
