Microwave-Sintered Regolith Bricks Assembled into a Shielding Vault

This study sizes microwave-sintered regolith brick production for a hemispherical shielding vault of 4 metre radius: each brick needs 18.3 megajoules at the stated coupling efficiency, the vault needs 1257 bricks, and total production energy is 23.0 gigajoules, about 128 hours at 50 kilowatts of microwave power. Brick mass is 12.0 kilograms. Sizing follows from computed thermal and regolith budgets derived in the study. This is a computed study with no targeting or weapon application. The work is simulated and computed from stated assumptions, not measured.
