Mass Driver on the Moon

… Elon Musk shares a 41-second video clip from a presentation envisioning "Moonbase Alpha," featuring a mass driver launching AI satellites into deep space at 1,000 TW/year, as the first step toward self-sustaining lunar cities and interplanetary exploration.

The concept draws from Robert Heinlein's 1966 novel The Moon Is a Harsh Mistress, where lunar mass drivers enable resource exports; real-world feasibility is supported by NASA's electromagnetic launch studies, leveraging the Moon's 1/6th Earth gravity for fuel-free payload acceleration up to escape velocity.

This ties into Musk's multiplanetary vision via SpaceX and xAI, potentially enabling scalable AI deployment across the solar system, though challenges like lunar power infrastructure (e.g., solar arrays) remain, per peer-reviewed analyses in Acta Astronautica estimating multi-gigawatt requirements for initial prototypes.
