Can Aneutronic Fusion Compete? A 2026 Reality Check on p-B11 and D–He³ Concepts
When most articles talk about fusion energy, they focus on the deuterium-tritium (D-T) reaction — the near-term workhorse everyone expects. But there’s a quieter, more ambitious conversation taking place: aneutronic fusion. This refers to fuel cycles (like proton-boron-11, p-B¹¹, or deuterium-helium-3, D–He³) where the fusion products are mostly charged particles rather than neutrons. That means […]
