Guided Self Replicating Factory for Colonization of Solar System

TL;DR

This paper proposes the concept of a guided self-replicating factory (GSFR) on celestial bodies that can grow exponentially, eventually forming a Dyson Sphere civilization capable of supporting trillions of people.

Contribution

It introduces the design and growth model of GSFR, detailing its components and potential to evolve into a Dyson Sphere civilization using in situ materials.

Findings

GSFR can double its mass and power output approximately every 50 doubling periods.

After about 50 doubling periods, GSFR could support a Dyson Sphere civilization with trillions of inhabitants.

The system includes power generation, material production, shaping, assembly, and space transportation components.

Abstract

In this work we present the concept of guided self-replicating factory (GSFR). This factory would be established as a colony on the Moon, Mercury, Mars, or Asteroid Belt. GSFR would grow by using in situ materials in order to manufacture machines. The time it takes for GSFR to double it's mass and electric power output is called a doubling period. After about 50 doubling periods, GSFR would become a Dyson Sphere civilization, which can house $10^{16}$ people, $10^{19}\ tons$ of structure and machinery and have a gross electric power of $3 \cdot 10^{24}\ W$. GSRF would contain four parts. Electric power station would generate electricity for all other parts. Material production system would gather ores or native metals and produce metals, plastic, and propellant. Material shaping and assembly system would shape metal and plastic into details. These details would be assembled into machines. These machines would be added to all four parts of GSFR. Space transportation system would use fuel manufactured in situ manufactured in situ in order to facilitate transportation of machinery and astronauts from Lower Earth Orbit (LEO) to the colony. During later stages, space transportation system would also use spaceships fully or partially manufactured from space colony material.
