This episode covers GRU Space building the first lunar hotel and the US government's controversial block of Anthropic's advanced AI models.

Geopolymer Binders Offer an Energy-Efficient Alternative to Sintering for Lunar Construction

Instead of energy-intensive methods like laser sintering, GRU Space uses a geopolymer brought from Earth to bind lunar regolith into bricks. This approach is more feasible given the significant power constraints on the moon.
