The Quest For Clean Drinkable Water,

has taken another turn,

if this solution to providing it by a UK group Seawater Greenhouse Ltd. really takes hold, it has developed greenhouses that provide fresh drinking water and can grow plants in areas that are as dry as a desert, they are already installed in places like Tenerife, Qatar, Abu Dhabi, Oman and Australia, but unlike a normal desalinization plant that uses large amounts of energy, this plant takes a different approach, by using an evaporative process to remove the salt, ventilation air that is driven by wind is cooled, cleaned, sterilized and humidified by seawater evaporators, only the pure water evaporates and is then collected, the initial cost of installation is high, but then so is a normal desalinization plant, but once installed the company claims that the running costs becomes far more reasonable than the alternative, a great idea that seems to work.
