Abstract
Water movement in shallow waters is used to obtain electrical energy. Some systems use panels (4) that are pivotally mounted (13) near the sea floor in shallow water and that extend up to the sea surface, or that are pivotally mounted above the sea surface and extend down into the sea. Electricity is obtained by stretching and relaxing capacitor devices that each has a sheet (188) of elastomeric material and has electrodes (184, 186) at the sheet opposite faces. In one system, a pair of capacitor devices (180, 182) lie in a cylinder (152) that holds a piston head (160) and the cylinder or the piston head is attached to a float and the other is fixed on the sea floor. Upper and lower ends (190, 194, 197, 199) of the devices are mounted so when one capacitor device is stretched (180B) the other is relaxed (182B).
