Potential NASA Commercial Applications: The proposed Solar Plant Growth System for Food Production is for application to: 1) onboard a crewed spacecraft such as the Deep Space Habitat or ISS where compact and efficient solar photosynthetic life support is required; and 2) a Lunar, NEO or Mars base where large scale food production and life support are implemented. The conventional concept for plant lighting is to employ electric lamps such as fluorescent, or high-pressure sodium (HPS) lamps or light emitting diodes (LED). With this conventional system concept, it is difficult to achieve high photosynthetic food production without causing unmanageable parasitic heat loading. For the proposed system, only the PAR spectra are delivered to the plant growth chamber by a compact flat lighting panel, thereby reducing most of the parasitic heat generation in the habitat. The proposed solar lighting system can also be utilized to supply solar thermal power to the habitat by changing the PAR mirror to the full spectral reflective mirror. Thermal power delivered to the habitat can be used for: habitat thermal control; manufacturing; and material processing. PSI has demonstrated such applications of the solar power system in our previous NASA program related to ISRU. The system concept discussed in this proposal has many other NASA applications such as material recycling such as nutrient re-use, and pollution removal from water (rhizofiltration) in human habitat.
