Poseidon Floating Power - Poseidon 37

Poseidon is a concept for a floating power plant invented by the Danish company Floating Power Plant AS (formerly Poseidon Floating Power). The plant is a hybrid design consisting of a wave energy converter that also acts as a floating foundation for three wind turbines. The plant transforms wave energy into electricity through hinged floats, piston pumps and a water turbine. The Poseidon 37, or P37, was demonstration and test plant in scale 1:4 that was launched in the autumn of 2008 and was moored within an existing wind turbine farm in Denmark. The plant consisted of 33 kW of installed wind power capacity and 50 kW of installed wave power capacity (only the wave power capacity is noted on this project page) .
