Patent ID: 8689556

Claim:
An energy producing device, comprising: an energy producing device vessel; a temperature-responsive material adapted to undergo density changes in response to temperature changes; a hydraulic fluid operatively associated with the temperature-responsive material, the hydraulic fluid adapted to be controlled within the energy producing device in accordance with the density changes of the temperature-responsive material; a first pressurized storage compartment configured to store the hydraulic fluid upon the density change of the temperature-responsive material; a hydraulic motor body fluidically connected with the first pressurized storage compartment, the hydraulic motor body being a rotating hydraulic motor body converting hydraulic pressure and fluid flow into torque and angular displacement of a rotating member of the hydraulic motor body; a first valve adapted to allow hydraulic fluid passage from the first pressurized storage compartment into the hydraulic motor body; an energy storage component connected with the hydraulic motor body, the energy storage component being chargeable by the hydraulic motor body upon passage of the hydraulic fluid through the hydraulic motor body thus obtaining conversion of hydraulic energy to electrical energy; and a second pressurized storage compartment configured to store the hydraulic fluid after passage of the hydraulic fluid inside the hydraulic motor body, wherein said first pressurized storage compartment, said hydraulic motor body, said second pressurized storage compartment and said energy storage component are located inside the energy producing device vessel.
