A new invention from Dalhousie University could provide a sustainable solution to global water scarcity.
A team of scientists at Dalhousie University in Halifax, Nova Scotia, has developed a groundbreaking device that could revolutionize water desalination . The device, a floating solar still , harnesses the sun's energy to purify seawater. It minimizes thermal losses, prevents salt buildup and can withstand harsh maritime conditions.
The solar still operates through a simple process: ocean water is drawn up to the device's foam surface, evaporated by solar-heated plasmonic materials, and then condensed on a clear plastic dome. The purified water is collected in a sealed bag. This device uses unconventional materials, such as recycled tires, transformed into a crucial component of the desalination unit through pyrolysis. It can simultaneously desalinate, disinfect and decontaminate water at a remarkably low cost and also generate a small amount of thermoelectricity. The team's next step is to conduct further testing in South Asia, with the ultimate goal of making the device available worldwide
