Producing electricity on the Moon at night

System for producing electricity on the Moon. Fresnel reflectors (dark blue and grey mirrors) will concentrate solar rays into the elongated collector above. Beneath, there is a tube filled with fluid that transforms into a gas when heated. This heats the thermal mass or reservoir (grey box), which can transfer it to a Stirling engine (cross-shaped object) to produce electricity. The radiator (green) can heat rovers and crew. The yellow cover prevents the heat from rapidly dissipating. (Credit: Blai Climent et al.)
