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.
