Fiber Optic Waveguide for Solar Concentrator Power Transfer

Lunar In-Situ Resource Utilization

Lunar Resource Utilization

Initial Application Target: O₂ from Regolith

PSI has developed an optical waveguide transmission cable to collect high quality mirror-focused solar power and relay it using fiber optic cables to processes needing efficient power for heat generation. The system concentrates solar flux ~1000x (1.3 kW/m2 to 1.3 MW/m2. The cable was developed to support the NASA Carbothermal Reduction Demonstration (CaRD) for oxygen production from Lunar regolith simulant.

Key Features

  • High concentration ratio ~1000x solar power collection
  • Wide input angle: NA ~0.32
  • Designed to provide >1.3 kW of solar power in a <3.8 cm diameter illumination spot
  • Leverages abundant Lunar South Pole ISRU energy source, solar power
  • Enables processing of Lunar regolith for a variety of uses, including oxygen production, sintering and melting for construction materials
Optical Waveguide Inlet Design and as-Built Cable for Solar Concentrator Power Transmission Applications.

Benefit to Customer

Efficient optical waveguide-based solar power transmission tool for Lunar ISRU heating applications: e.g. O₂ from regolith
