Summary
A detailed engineering analysis outlines the fastest physically plausible disassembly of Mercury into Dyson swarm components using current materials and manufacturing techniques. The process starts with a 1,000-tonne self-replicating industrial seed and grows through approximately 58 doublings, achieving a Mercury-local industrial economy that maximizes intercepted sunlight.
Key Takeaways
- A 1,000-tonne self-replicating industrial seed on Mercury can grow through approximately 58 doublings to reach a mass of 3.3 × 10²³ kg.
- Mercury's intercepted sunlight limits its local industrial economy to about low-30s doublings before requiring additional power sources.
- Waste heat management is a critical engineering constraint for industrial operations on Mercury, necessitating off-planet thermal processing.
- The total solar power intercepted by Mercury is approximately 1.7 x 10¹⁷ watts, establishing a geometric ceiling for solar-based energy strategies.

Concerns
- The proposal overlooks the significant challenge of Mercury's deep gravitational well, suggesting that the mass alone does not justify the project's feasibility.
- The idea of bootstrapping an electronics supply chain on another planet appears overly optimistic, potentially complicating the implementation of the Dyson swarm.
