The sun and the sea—both abundant and free—are being harnessed in a unique project to create vertical sea farms floating on the ocean that can produce fresh water for drinking and agriculture.
Freshwater accounts for just 2.5% of the world’s water and most of this is not accessible because it’s trapped in glaciers, ice caps or is deep underground,” Dr. Owens says. “It’s not that freshwater is dwindling either, but the small amount that exists is in ever increasing demand due to population growth and climate change.
“The fact that 97.5% of the world’s water is in our oceans—and freely available—it is an obvious solution to harness the sea and sun to address growing global shortages of water, food, and agricultural land. Adopting this technology could improve the health and welfare of billions of people globally.”
