Design Blueprint: Microwave-Sintered Regolith Bricks Assembled into a Shielding Vault

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24189082): 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. Status: DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. All numbers are simulated values from the source paper's computation, deposited with this blueprint as compute.py and results.json.
