Elon Musk teases 'cannon-like' mass drivers for launches from moon

Elon Musk has unveiled an ambitious plan called Project TERAFAB to build massive AI data centers on the Moon, leveraging its unique environment to overcome Earth’s energy and space limitations. The concept centers on constructing electromagnetic mass drivers—large “cannon-like” tracks that use magnetic fields to launch AI satellites directly into lunar orbit without relying on chemical rockets. This approach takes advantage of the Moon’s vacuum, low gravity, and abundant solar energy, which is about five times more efficient than on Earth, enabling petawatt-scale AI computing far beyond current terrestrial capabilities. The plan envisions a lunar factory using robotics to manufacture solar-powered AI satellites, which would then be accelerated into orbit via either railgun or coilgun mass drivers, with coilguns preferred for their controlled acceleration suitable for sensitive payloads. While the idea of magnetic space launchers dates back to 1937, it remains theoretical and would require enormous logistical efforts, including potentially 135 Starship launches daily to transport the needed materials.
