Abstract:
A system for generating electricity by gravity comprising:an upper water reservoir; a lower water reservoir; a conduit connecting said reservoirs; a pump connected to said conduit for pumping water from said lower reservoir to said upper reservoir; an electric generator for generating electricity; a plurality of containers positioned side-by-side and mounted for up and down travel between said upper and lower reservoirs; filler means for filing said containers with water from said upper reservoir when said containers are at an upper-most position adjacent said upper reservoir; drain means for draining water from said containers into said lower reservoir when said containers are at a lower-most position adjacent said lower reservoir; guide means for guiding the up and down travel of said containers between said upper-most and lower-most positions; motor means connected for driving said drained containers from said lower-most position to said upper-most position; upper limit switch means for retaining and filling said containers with water from said upper reservoir when said containers attain said upper-most position and for releasing said containers when filled for downwardly guided gravity travel; lower limit switch means for retaining and draining said containers into said lower reservoir when said containers attain said lower-most position and for releasing said drained containers and energizing said motor means for upwardly travel of said containers when drained; and said containers connected in driving engagement with said electric generator when said filled containers are traveling downward for driving said electrical generator to generate electricity.
