The world is about to gain its first publicly traded ‘pure-play’ fusion company, and it's determined to deliver energy from nuclear fusion with an innovative model that uses neither magnets nor lasers, the most common components of leading fusion experiments. Instead, the model being piloted by the fusion-exclusive startup General Fusion uses mechanical pistons to contain plasma within a liquid lithium shell. Interesting Engineering reports that the technology has been described as a “practical, mechanical approach to fusion,…
