How to build a lunar mass driver
Elon Musk has proposed building a lunar mass driver to facilitate the launch of AI components from Moon factories. This concept leverages the Moon's low gravity and aims to enhance the profitability of space-based data services. However, the economic viability of such a project remains uncertain due to high launch costs and limited market demand for lunar materials.
- ▪Elon Musk has been discussing the construction of a lunar mass driver to launch components from Moon factories.
- ▪The Moon's low gravity and lack of atmosphere make it a suitable location for such a project.
- ▪The economic feasibility of launching materials from the Moon is challenged by high costs and limited demand.

Elon has recently (late 2025, early 2026) been talking about building many terawatts of orbital AI compute and launching some components from Moon factories with a mass driver. This is an old idea, enabled by the Moon’s relatively low gravity and lack of an atmosphere. See, for example, The Moon is a Harsh Mistress and The High Frontier.
