Waste water to clean energy: Japanese engineers harness the power of osmosis

Fukuoka, Japan (AFP) April 3, 2026 A Japanese water plant is harnessing the natural process of osmosis to generate renewable energy that could one day become a common power source. The possibility of generating power from osmosis - when water molecules pass from a less salty solution to a more salty one - has long been known. But actually generating energy from that has proved more complicated, in part due the difficult
