US Patent 7444811 Wave power device

Wave-power device, with a plurality of floating bodies (12) arranged in at least two parallel rows for vertical movement caused by wave movements. Each floating body is connected to a generator (22) for the generating of electrical energy during the vertical movement. The floating bodies are jointed to a raft (11) which can be relocated on the water and can be moored at an arbitrary place of use. The floating bodies (12) are connected to vertical supporting bars (14), which are held between an upper lattice-like structure (15, 16) and a lower lattice-like structure (17, 18), and each of the vertical supporting bars (14) is connected to an electric generator (22).
