Title:
GRAVITY-OPERATED WATER ENGINE
Document Type and Number:
WIPO Patent Application WO2005091706
Kind Code:
A3
Abstract:
A method of producing energy comprises buoyantly raising a hollow air container (15) made of a material whose specific weight is much heavier than 1 in a vertical well housing (5) by delivering water to successively higher levels of the well housing (5); allowing the water to pass from the well housing (5) to successively lower levels to empty the well housing; and using the potential energy of the air container (15) by lowering the air container, after it has been buoyantly raised and the well housing (5) has been emptied. In a gravity driven water engine for performing the method, the water is transferred between the well housing and a space-water room (8) contiguous with the well housing (5), the water room having many levels of water reservoirs (80). Each reservoir (80) has an upper water inlet (10) with a water inlet valve (10A) and a lower water outlet (11) with a water outlet valve (11) that deliver water in succession from the well housing (5) to successively lower reservoirs (80) to progressively empty the well housing and from successively higher reservoirs (80) to the well housing (5) to progressively fill the well housing.
