Version 3.0 resolves four gaps from Version 2.0 and adds a new analysis of Earth's magnetic field as analternative MHD source. The Earth field analysis produces an important honest finding: at 50 microtesla,Earth's field is 6,000 times weaker than NdFeB permanent magnets, and power scales as B-squared —making Earth's field 36 million times weaker per unit volume than permanent magnets. Direct substitutionof Earth's field for permanent magnets in cable-mounted MHD modules is not viable. The analysisidentifies two unconventional paths with genuine potential: superconducting rotating loops (13.5 kW at100m radius, 1000 turns, 1 rpm) and continental-scale ocean electrode arrays (2.0 kW from a 10km ×10km × 200m array). Both require enabling technologies not yet at commercial readiness. Additionally,V2.0 MHD power figures are corrected: the stated 60-90 kW per module was overstated by approximately150x. Verified correct output for a realistic 20m × 3m × 2m ocean module is 437 W (0.44 kW). MHDhybrid generation remains a valid supplementary system but contributes approximately 22 kW total from50 modules — 0.13% of total system output — rather than the previously stated 2.4-5.4 MW. Chaostheory quantification establishes Lyapunov exponents of 0.10–0.30 per hour with predictability horizons of7.7–23.0 hours. Jensen wake model analysis revises turbine spacing to 30D (600m) improving MHDplacement efficiency. A fourth AI control loop for MHD power conditioning is specified at 30-secondupdate cycles.
