Aus Abwasser saubere Energie: Japanische Ingenieure nutzen die Kraft der Osmose

> 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 difficulty of designing the membrane through which the molecules pass.

> Engineers in the city of Fukuoka and their private partners think they might have cracked it, and have opened what is only the world’s second osmotic power plant.
