In cold countries, greenhouses, hothouses and greenhouses are built to artificially create a warmer environment plant organisms. In hot countries - the opposite. The Orangery - saving acts screen protecting plants from the hot and dry air. Evaporating moisture remains in a closed system greenhouse.
Currently at the design stage is an ambitious project for planting Sahara. Water is needed for watering plants and humidification "greenhouses" creators of the project are going to get through the distillation of sea water. Distillation will occur due to the energy of the sun. These greenhouses are already operating in Tenerife, Oman and the United Arab Emirates.
