The solar receiver comprises a housing (2) and a window (3) disposed in or on a wall (4) of the housing (2), wherein the window (3) comprises vitreous silica having an OH content of 30 ppm or more by weight.

The solar receiver of this application addresses the problem of the limited efficiency of the prior art receivers by using a window comprising vitreous silica having a relatively high OH content of 30 ppm or more by weight.

Abstract: A water vapor ejector comprises a desiccant disposed in a communication path to a green house enclosure. In the day time and under sunlight exposure, the green house enclosure heats up, which dries the desiccant and generates a flow to the outside ambient through a pressure difference. The moisture trapped in the desiccant is then released to the outside ambient. In the night time, the green house enclosure cools, which generates a flow to the inside of the enclosure. The desiccant traps the moisture within the flow, ensuring a moisture-free enclosure. The cycle re-starts in the next morning when the enclosure heats up. The diurnal cycle removes the water vapor present in the enclosure and delivered to the exterior of the enclosure.
