TAE Technologies just took a giant leap toward aneutronic fusion using hydrogen–boron (p–11B). While most fusion projects chase the easier deuterium–tritium fuel cycle, TAE is pursuing something cleaner, harder, and far more disruptive. In April 2025, they published a breakthrough showing they can form a stable FRC plasma without their massive 100-GW starter system — simplifying the reactor, cutting costs, and improving performance.
