Devices and methods for concentrated radiative cooling using radiative cooling coatings in combination with mid-infrared reflectors. Concentrated radiative cooling (CRC) devices include an object to be cooled that is coated with a radiative cooling material and a mid-infrared (mid-IR) reflector configured to reflect thermal energy radiated from a surface of the object to deep space. The object may be nested in a mid-IR reflective trough such that substantially an entirety of the object's surface area contributes to radiative cooling. The radiative cooling material may be a coating such as a paint or film that is applied directly to the object's exterior surfaces to reduce thermal resistances. The radiative cooling coating is configured to lose thermal energy from the object by means of exhibiting high emissivity for wavelengths of 8 to 13 micrometers, and in some arrangements of 5 to 30 micrometers.

A solar thermal collector and an accessory structure of a building are provided. The solar thermal collector includes at least one heat absorbing plate and at least one heat insulating plate. Each of the heat absorbing plate includes at least one first slab and first engaging parts connected with the first slab. Each of the heat insulating plate includes at least one second slab and second engaging parts connected with the second slab. The first engaging parts are respectively engaged with the second engaging parts, and a gap is maintained between the first slab and the second slab to define a heat collecting channel, through which a heat transfer fluid flows between the heat absorbing plate and the heat insulating plate. A heat conductivity of the heat absorbing plate is at least 30 times greater than a heat conductivity of the heat insulating plate.

Solar energy is collected and used for various industrial processes, such as oilfield applications, e.g. generating steam that is injected downhole, enabling enhanced oil recovery. Solar energy is indirectly collected using a heat transfer fluid in a solar collector, delivering heat to a heat exchanger that in turn delivers heat into oilfield feedwater, producing hotter water or steam. Solar energy is directly collected by directly generating steam with solar collectors, and then injecting the steam downhole. Solar energy is collected to preheat water that is then fed into fuel-fired steam generators that in turn produce steam for downhole injection. Solar energy is collected to produce electricity via a Rankine cycle turbine generator, and rejected heat warms feedwater for fuel-fired steam generators. Solar energy is collected (directly or indirectly) to deliver heat to a heater-treater, with optional fuel-fired additional heat generation.
