​Multi-Technology Synergy to Grow Food in the Desert

June 20, 2013 · Print This Article

A project in Qatar is putting together a number of different systems in a complex project intended to “produce food, fresh water and clean energy in deserts using seawater.” The Sahara Forest Project uses a number of different systems where the waste by-products from one process are used as feedstock for another. It began by focusing on what was readily abundant: seawater, sun, and desert sand, and looking to what was

needed: food, energy, and clean water.

“The seawater, pumped from the nearby Persian Gulf, is the system’s lifeblood. It’s used to cool and humidify the greenhouses. It’s plus used to grow algae to produce biofuel, with the leftovers from that process going to prepare animal feed. Some of it is transformed into fresh water by a solar-powered desalination unit. Some of it may even be used down the road to raise […]
