Stunning video footage shows plasma swirling in fusion reactor

British fusion company Tokamak Energy released stunning high-speed footage showing hydrogen plasma swirling in their donut-shaped reactor at temperatures hotter than the Sun's core. The video captures the plasma's pink glow and lithium grains changing from brilliant red to bright green as they're injected into the chamber. While fusion energy remains impractical since it requires more energy input than output, the colorful footage helps scientists identify gaseous impurities and track material penetration.
