The largest dam-removal project in history reached completion last fall, when excavators dredged the final tons of pulverized concrete from the Elwha River channel in Western Washington. Native fish, banished for 100 years from their historic spawning habitat, already were rediscovering the Elwha’s newly accessible upper stretches. Within weeks of the final explosion in August, threatened bull trout and chinook salmon were spotted migrating beyond the rubble.
A workable wave power unit using hydraulics. They are pressurising sea water to drive land-based hydroelectric power generation or reverse osmosis desalination…

A new irrigation system takes saltwater and transforms it into pure water vapor to grow crops.
