The Greening Of The Sahara
The intent of the inventors is surprising: they propose to establish in the Sahara, extensive greenhouses, which would use several innovative technologies. Combining solar thermal power plants of the type and original of desalination plants would allow the Sahara Forest literally out of thin air to produce food, fuel, electricity and drinking water that would have transformed the entire region.
Solar thermal power plant needs to concentrate light on a boiler, which boils water and the resulting steam drives the turbine generator. The resulting electricity will be used on special “greenhouses that use sea water — Seawater Greenhouse located around.
Fresh sketch demonstration phase of the "Sahara Forest". Probably, and will look to pilot complex in Aqaba. In the near term – the administrative and technical buildings. A little further is solar thermal power plant (in this case, it is built on the basis of horizontal parabolic troughs, although in theory it could be a small tower with a field of heliostats), followed by three bars of greenhouses. Closer to the sea and around the exposed planting grain. On the shore of the sea of the Gulf desalination plant (illustration of the Sahara Forest Project Foundation/Screenergy).
And Seawater Greenhouse reduces water consumption for irrigation. The relatively cool air with a relative humidity of 90% under the unusual roof greenhouses, reduces water evaporation from the leaves.So, for example, in Tenerife, where one of these buildings, the owners spend on watering 1.2 liters per square meter per day, while the farmers who grow culture according to the traditional scheme, as much as 8 liters.
Authors calculated that a large-scale system of the "Forest of the Sahara" may be cost-effective. And most importantly, both key technology has long been tested separately. In the world there are already several solar "concentrating" power plants at industrial scale. Greenhouses with sea water is also tested in a number of countries, at least as experiments.
