Mass. Every kilogram you send to the lunar surface costs a fortune to lift, and a reactor’s shielding and foundation are the heaviest, dumbest mass in the whole system - dense material whose only job is to sit there.

So we don’t send it. We make it.

Autonomous laser sintering fuses lunar regolith into the dense, structural mass a fission reactor needs - shielding, foundations, containment - using the material that’s already underfoot. You launch the smart parts. You build the heavy parts on site.

That inversion is the whole thesis: stop treating the Moon as a place you ship infrastructure to, and start treating it as a place you manufacture infrastructure from.
