Low-Energy Water Desalination From Seawater Greenhouse
In these times where climate chaos has caused more frequent severe droughts, and our population continues to grow (read: consume water) at an awesome rate, people are becoming more and more concerned with water conservation. Humanity finds itself increasingly at a loss for freshwater while roughly 315 million trillion gallons of unusable seawater taunts us from our shores.
Sure, desalination plants are becoming more common. They are very expensive, however, and so energy intensive that they only further contribute to the climate change they are attempting remedy (thereby, joining corn-based ethanol as the two largest non-solutions to our climate problems).
Fear not my fellow water-loving earthlings! There is an even better way to remove the salt from salt water: a Seawater Greenhouse! This UK-based company explains the process as one that:
uses seawater to cool and humidify the air that ventilates the greenhouse and sunlight to distill fresh water from seawater. This enables the year round cultivation of high value crops that would otherwise be difficult or impossible to grow in hot, arid (conditions).
