Described herein are embodiments directed to collecting vaporize gas via a CPC arrangement. The CPC arrangement generally comprises a transporter that carries around a cover with one or more cryogenically cooled plates (or some other cryogenically cooled surface) therein. A plurality of CPCs dispersed on the transporter each have a concave reflective bowl that captures and directs sunlight through a fiberoptic cable where the sunlight is focused on regolith in an internal environment defined within the cover when resting atop the regolith. The focused sunlight heats the regolith and liberates the gas from the regolith, which is trapped in the internal environment. The gas in the internal environment condenses on the cooled plates where it can be collected and processed.

A self-sustaining farming system includes a building with aperture(s) in a side of the building. Reflected sunlight from heliostats adjacent the building is directed to and passes through the aperture(s) and through light tube(s) that direct light onto plants disposed inside the building proximate the light tube(s). A portion of the reflected sunlight is directed to a photovoltaic panel for generating electricity that is used by components and electronics in the building. A portion of the reflected sunlight can be converted to heat that can be stored in a heat storage unit for use in maintaining the internals of the building at a controlled temperature and/or to generate water from air, the water used to irrigate the plants in the building. The system utilizes all of the spectrum of sunlight to provide a self-sustaining farming environment that can operate in remote locations (e.g., desert) using only sunlight to grow plants.
