Water desalination. Water desalination plant of the type comprising a distiller 13, a pump 14 for drawing in the water to be desalinated and to deliver it in the form of rain into the distiller 13, a vacuum pump 26, a pump 23 for drawing in the distilled water and delivering it towards a storage tank 30. Means 34 for discharging the unevaporated salty water from the distiller 13 and at least one air generator 1, characterised in that it comprises a battery of electrical storage batteries inserted between the air generator 1 and a panel 8 of photovoltaic cells so as to be capable selectively of being charged by either or both of these generators and connected electrically to the supply of the vacuum pump 26 with interposition of means for controlling the supply to the said vacuum pump from the battery 7 if the wind speed falls below a determined threshold. <IMAGE>
