Abstract

Moving fluid energy conversion device (90) converts mechanical energy contained in moving fluid (16) to electrical energy. Moving fluid energy conversion device (90) comprises one or more transducers (10), a charge exchange means (600), a charge element (62) and a recovery element (65). Transducer (10) is comprised of one or polymer spacers (502) sandwiched between one or more top electrodes (504) and bottom electrode (506) pairs. Moving fluid energy conversion device (90) produces electrical energy by transferring electric charge from charge element (62), through charge exchange means (600) to transducer (10) in stretched state (6). Transducer (10) is then allowed to return to relaxed state (8). The charge in transducer (10) increases in energy when the transducer (10) returns to relaxed state (8). The increased energy electric charge flows to recovery element (65) through charge exchange means (600).

Dependent claims

A moving fluid energy conversion device for converting mechanical energy contained in a moving fluid, to electrical energy, said energy conversion device wherein the improvement comprises:

a. one or more transducers, each transducer comprising one or more pairs of electrodes and one or more polymer spacers with the one or more spacers sandwiched between said one or more pairs of electrodes in a configuration that causes a change in electric field in response to deflection of a portion of said one or more polymer spacers;
and
b. one or more charge elements designed or configured to transfer electrical energy to said one or more pairs of electrodes when said portion of the spacer is deflected to a first position;
and
c. one or more recovery elements designed or configured to transfer electrical energy from said one or more pair of electrodes when said portion of the spacer is deflected to a second position;
and
d. one or more means for impinging said one or more transducers with said moving fluid causing said one or more polymer spacers to stretch from a relaxed state to a stretched state;
