A hydroelectric generator comprises a header tank 1, a pipe 2 leading to a turbine 3, and a generator 4 powered by the turbine. Water 20 passes from the header tank 1 to a second tank 5via the turbine 3, thus causing generator 5 to generate electricity. Water is returned to the header tank through pipe 14 via pump 13. Pump 13 is preferably powered via solar panel 16. Alternatively water is returned using a wind powered pump 6, or by capillary action via pipes 15, 17. The header tank may initially be filled by water via mains 8, by rainfall 10, or from a water course or bore hole or other means. A venturi 21 may provided in pipe 2 leading to the turbine to modify fluid flow and/or head. The apparatus may be provided in a housing, and may be located at or in a building, a tower or underground. |
