Australia to open first wave power plant

Australia's first commercial wave-generated power station will in weeks begin supplying homes south of Sydney with electricity and fresh drinking water, courtesy of the sea.
Electricity is generated when waves wash into a funnel facing the ocean, driving air through a pipe and into a turbine capable of pumping 500kw of clean power each day into the local grid.
The $6m floating plant, built to withstand a one in 100-year storm, can also desalinate 2000 litres of drinking water each day for almost as many homes as it powers.
