Most fusion concepts end in a boiler. MetroVolt's D-³He cycle delivers the majority of its power in charged particles and radiation, so the plant harvests through a multi-modal train: direct electrostatic conversion, radiation-to-electric surfaces, and a compact bottoming cycle.
The deposited Table-22 power ledger runs the plant end-to-end. At the Mode-D operating point (exhaust-honest, f_exh = 0.18 honored by construction): 1,221 MW fusion yields 652 MW gross and 486 MW net electric, Q_eng = 3.9 — with the photon channel (876 MW of radiation at η_γ = 0.20, ≈175 MWe) as the direct train's largest working line. The Mode-C hot-ion columns (0.61 / 0.84 GWe) are retained as the labeled ceiling record. Every intermediate line is printed and reproducible.
Direct conversion of charged-particle streams at high efficiency has experimental heritage in plasma direct converters; MetroVolt's contribution is an integrated, gated design that never books credit beyond what its own exhaust-physics analysis (S51/S65) supports.
Skipping the full steam detour raises plant efficiency and deletes cost: less turbine hall, less cooling infrastructure, faster load response. The two-posture ledger gives buyers a floor and an upside on the same machine — with the operating floor stated first and the ceiling explicitly gated.
