But in a groundbreaking mission to mitigate the global water crisis without further contributing to carbon emissions, a Canadian company, Oneka Technologies, is pioneering an innovative approach to desalination. The Quebec-based startup has developed an avant-garde solution that harnesses the boundless energy of the ocean waves to convert saltwater into fresh, drinkable water. Oneka Technologies’ floating desalination units, anchored securely to the ocean floor, utilize a membrane-based system, known as reverse osmosis, to purify seawater. The process is elegantly simple: wave energy is converted into mechanical energy, powering pumps that draw in seawater and push a portion through a semipermeable membrane to filter out the salt. The result is clean, potable water delivered to shore through pipelines, propelled by the very force that generated it: the undulating waves of the sea. “Oneka's technology is 100% mechanically driven," Hunt told the BBC, underscoring the zero-electricity operation of their machines. Such innovation represents a seismic shift towards sustainability in desalination practices.
