Desalination is seen as a path forward to ensuring coastal communities have a steady supply of clean drinking water as populations expand. Historically, desalination projects have struggled to scale widely, as the high amount of energy required to remove salt from ocean water creates costs and damages sustainability. A Quebec, Canada firm has developed a product to address the energy and environmental concerns of desalination by making a modular, floating buoy that harnesses the power of the sun and waves to turn ocean water into drinkable water. Oneka builds a self-contained, solar-topped device that also harnesses tidal power. The two energy sources allow the buoy to draw ocean water in through reverse osmosis, and then convert it to drinkable water.
