The US National Ignition Facility at Lawrence Livermore National Laboratory (LLNL) in California recently announced an inertial confinement fusion energy gain of 50%, attracting considerable public press. LLNL is a weapons lab interested in fusion study rather than commercial applications, and the lasers they used to create light energy input to these events are well under 1% efficient, so other approaches (most famously magnetic confinement via tokamaks and toroids) might be used for commercially developed fusion power. Several other innovative commercial R&D efforts are under way, like that of Helion Energy’s pulsed plasma compression scheme (modified magnetic confinement), with details in “Real Engineering” videos also addressing concerns for “potentially practical fusion.” Sabine H. also mentions First Light Fusion from Oxford University, who are using an extremely high-velocity gas gun in their inertial confinement approach.
