Linear dual EAP generator

摘要

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).

主权项

1. Apparatus for generating electricity from motion of a sea, by converting repetitive motion of a first part relative to a second part into electrical energy, comprising:
first and second capacitor devices that each comprises a stretched sheet of elastomeric material with opposite ends, and electrodes at opposite faces of the sheet, with the electrodes carrying a voltage between them that varies as the devise is stretched and relaxed; means for connecting said ends of said capacitor devices to said first and second part in an arrangement wherein when one of said parts moves relative to the other part, one of said capacitor devices undergoes increased stretching and the other of said capacitor devices undergoes a reduction of stretching.
