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.
In what is believed to be a world first, University of South Australia researchers have designed a self-sustaining solar-driven system that evaporates seawater and recycles it into freshwater, growing crops without any human involvement.
It could help address looming global shortages of freshwater and food in the decades ahead, with the world’s population expected to reach 10 billion by 2050.
Professor Haolan Xu and Dr Gary Owens from UniSA’s Future Industries Institute have developed the vertical floating sea farm which is made up of two chambers: an upper layer similar to a glasshouse and a lower water harvest chamber.
