# General Fusion says metal compression heated plasma to 12 million degrees Celsius

General Fusion says it heated plasma to 12 million degrees Celsius by compressing it with a rapidly imploding metal wall, demonstrating a core part of its approach to fusion power.

The Canadian company's Magnetized Target Fusion method combines magnetic confinement with mechanical compression. Pistons compress a liquid metal liner around magnetized plasma, raising its density and temperature. The liquid metal can also absorb fusion neutrons and carry heat away for electricity generation.

The reported temperature falls short of ignition, which the article says requires hundreds of millions of degrees.
