A New Way to Achieve Nuclear Fusion: Helion

Real Engineering · explainer · Watch on YouTube

What it is

Real Engineering's Brian McManus explains Helion's approach to nuclear fusion: colliding two plasma rings, compressing them magnetically, and capturing energy directly from the changing magnetic flux rather than boiling water. It covers why this pulsed design sidesteps problems of tokamaks and laser fusion.
