Design of a Space-Faring Self-Sufficient UFO City for 30,000 People

Design Overview of a Self-Sufficient UFO City for 30,000 People

To enable 30,000 people to live self-sufficiently inside a massive UFO structure with a diameter of 2 to 4 km—while also surviving in outer space (e.g., between Earth and the Moon or Earth and Mars)—the following structural, ecological, and technological components are required.

1. Required Area and Structural Design

Population Basis: Approximately 30,000 people

• Living space: 25㎡ per person → 750,000㎡ total

• Food production space: 50㎡ per person → 1,500,000㎡ total

• Public facilities (schools, hospitals, shops): 10㎡ per person → 300,000㎡ total

• Infrastructure and mechanical systems: 15㎡ per person → 450,000㎡ total

• Total Required Area: Approximately 3,000,000㎡ (3㎢)

Structure Type: Circular UFO with a diameter of 2 to 4 km.
A diameter of at least 2.5 to 3 km is sufficient for self-sufficiency for 30,000 people.

2. Essential Functional Zones

A. Residential Zone

• High-density multi-story structures

• Mixed layout: private, family, and shared units

• Noise, vibration, and temperature control systems included

B. Food Production Zone

• Multi-layer vertical farms with LED lighting

• Insect protein and cultured meat systems

• Automated waste-to-fertilizer recycling loop

C. Water and Waste Recycling

• 100% wastewater purification and reuse

• Air purification using plant-based systems and nano-filters

• CO₂ capture and conversion via plants

D. Energy Independence

• Fusion reactor or high-efficiency solar panels

• Power storage systems (e.g., superconducting batteries)

• Backup bio-gas and hydrogen fuel cells

E. Medical and Regenerative Technology

• Hospitals, clinics, pharmaceutical production

• 3D printing of artificial organs and tissues

• Space medicine and radiation countermeasures

F. Education, Culture, and Mental Health

• Schools, libraries, spaces for arts and therapy

• Areas for religion, meditation, and personal reflection

G. Propulsion and Navigation Systems

• Anti-gravity, ion, or nuclear propulsion engines

• Automatic and manual navigation systems

• Drones, exploration pods, and shuttlecraft

3. Required Technologies

4. Crew and Social Structure

• About 10–15% of the population are core specialists
  (doctors, biologists, engineers, AI operators, ecological designers)

• The rest are engaged in farming, security, education, services, welfare, and production

• Self-governance: hybrid of AI-assisted and democratic decision-making

• Internal economy: credit or token system based on labor and energy

5. Space Survival Conditions

• Rotational or artificial gravity system

• High-efficiency radiation shielding

• Long-term closed-loop food production

• Real-time communication relayed via Earth–Mars satellites

• Emergency modules and detachable survival capsules

Summary

• Population: Approximately 30,000 people

• UFO Diameter: Minimum 2.5–3 km, ideally 3.5–4 km

• Living Zones: Residential, food production, medical, energy, culture

• Core Technologies: Energy independence, full ecological recycling, artificial gravity, radiation shielding
