GB1580805A – Water Wave Energy Conversion Device Using A Flexible Walled Enclosure – Google Patents

Lifting facial con acupuntura - Alma Belleza y Salud The invention also provides a device for conversion of energy from water waves comprising an elongated flexible enclosure of impermeable material divided into compartments each containing gas, a high pressure gas conduit and a low pressure gas conduit, each compartment being connected to the gas conduits via non return valves arranged to permit one way passage of gas from the compartment into the high pressure gas conduit and to permit one way passage of gas from the low pressure gas conduit into the compartment, a rigid elongated support structure to which the flexible enclosure material is attached with the enclosure extending upwards in operation from its line of attachment to the rigid support with at least one side wall of the enclosure free to flex laterally, the device being located for operation in water with the top of the flexible enclosure approximately at or just below the surface so that as water waves pass along the device each compartment is subjected in turn to an external pressure alternation, gas being pumped when the external pressure is high from the compartment into the high pressure gas conduit and gas returning, when the external pressure is low, from the low pressure gas conduit into the compartment.
