Passive radiative cooling structures and apparatus manufactured with such cooling structures conserve energy needs. A flexible film transparent to visible light incorporates particles at a volume percentage larger than 25% so as to absorb and emit infrared radiation at wavelengths where Earth's atmosphere is transparent. Another film transparent to visible light is thin and flexible and configured to absorb and emit infrared radiation at wavelengths where Earth's atmosphere is transparent, wherein etchings or depositions are present on one or both surfaces. A high efficiency cooling structure has an emissive layer sandwiched between a waveguide layer and a thermal conductive layer. A solar cell panel is covered by a transparent passive radiative cooling film. A container housing an active cooling unit incorporates passive radiative cooling structures on one or more exterior surfaces.

Methods and systems for circulating hot air in a solar desalination system include a desalination structure having an air flow path defined between an external surface layer and an internal surface layer. A return flow conduit has a fan, a check valve, and a control valve. Saline water is delivered through a nozzle to provide a mist. An air flow within the air flow path is heated to form a hot air supply. The mist is heated with the hot air supply to form an evaporated fluid. The fan is operated to divert a diverted portion of the hot air supply into the return flow conduit to be mixed with an ambient air to form and heat the air flow. The volume of the diverted portion can be controlled with the control valve. The check valve prevents ambient air from entering the return flow conduit at a base end.
