Abstract: This corpus provides the complete case for accelerating fusion development — from plasma physics and engineering specification through environmental imperative to geopolitical urgency — across five coordinated papers.The technical foundation rests on a single validated principle: allowing plasma to self-organize into convection cells enables sustained confinement, continuous helium ash removal, and stable high-density operation. China’s EAST tokamak confirmed this empirically — 1066 seconds sustained H-mode in January 2025 (2.6× world record), followed by achievement of the “density-free regime” in January 2026 (Science Advances, DOI: 10.1126/sciadv.adz3040), demonstrating stable plasma at 1.3–1.65× traditional density limits through plasma-wall self-organization rather than suppression.The engineering specification (PMPS-LA v5.2.0) translates this physics into deployable hardware: a two-layer magnetic architecture with 288 binary-polarity coils at 10 µs response time, directly retrofittable to existing tokamaks (EAST/KSTAR/DIII-D/MAST-U). Two operational modes share identical hardware — slow burn (poloidal cells, 85–95% duty cycle, baseload electricity + byproduct He-4 at 20–50 kg/yr) and hot burn (radial cells, 10–20% duty cycle, medical isotopes and rare-earth transmutation products). Binary IGBT switching eliminates mutual inductance losses, reducing steady-state power consumption to <300 kW versus conventional RMP at 1.5–3 MW. Laser topological seeding (1–10 J, 1–5 ms pulses) nucleates flow 3–5× faster than natural self-organization. Phase 1 validation cost: £7M single-sector, 18-month path to full-array commissioning. Batch production by 2030 at ≤$300M/unit.The environmental paper establishes that accelerating ocean anoxia — driven in part by thermal pollution from AI and industrial infrastructure concentrated near coastal waters — is degrading Atlantic Meridional Overturning Circulation toward collapse. The AMOC collapse window is assessed at 2028–2035, consistent with Van Westen et al. (2025) and Van Westen & Dijkstra (2026), who identified abrupt Gulf Stream path changes as a precursor signal. The only mitigation strategy operating at the required scale — engineered cold-water injection via the Hawaiian pump concept (Mauna Kea/Haleakalā elevation to deep-ocean gravity feed) — demands continuous power output of hundreds of megawatts sustained over decades. Only fusion can deliver this economically. The coupling is direct: if fusion arrives before AMOC collapse, intervention is possible; after collapse, restoration may not be.The geopolitical capstone paper (March 2026) argues that the fusion timeline is not an abstract R&D question but the most consequential strategic variable in the current global order. Three dynamics are converging simultaneously: great-power consolidation into three defended spheres (China, Russia, United States), critical resource chokepoint vulnerability exposed by the February 2026 Iran conflict and effective closure of the Strait of Hormuz, and the AMOC destabilization described above. Each is driven by energy scarcity. Each is resolved by energy abundance. The paper provides timestamped, falsifiable predictions across geopolitics, trade, and alliance structures — including peaceful Taiwan reunification (2026–2030), Chinese fusion primacy (2030–2035), post-fusion global realignment cascades, and the structural trajectories of Japan, the Philippines, South Korea, Australia, Poland, the Baltic states, and Africa under tripolar competition. The analysis demonstrates that the nation achieving fusion first inherits not merely an energy advantage but the gravitational center of the next century’s global order.Across all five papers, the argument is unified: seventy years of plasma suppression failed; organized convection is validated; the engineering specification exists; the environmental and geopolitical clocks are running. Risk lies not in technology but in delay.Keywords: fusion energy; tokamak edge control; organized convection; pixelated magnets; binary polarity switching; laser topological seeding; helium economy; medical isotopes; energy sovereignty; AMOC collapse; ocean anoxia; geopolitical analysis; tripolar consolidation; energy scarcity; post-fusion civilization; China fusion race; PMPS-LA; EAST tokamak; Belt and Road Initiative
