20120274070 | METHOD AND AN INSTALLATION FOR PRODUCTION SUPPLEMENTARY ELECTRICAL ENERGY - An installation for producing supplementary electrical energy for an electricity network includes at least first and second water reservoirs, the first water reservoir being situated at a first level and the second water reservoir being situated at a second level lower than the first level, a communicating pipe between the first water reservoir and the second water reservoir being provided with a remote-controlled valve, and a hydro-electric generating system being provided with a pumping installation. The first and/or second water reservoir is integrated in the foundations in the lower portion of an artificial building that needs to be built for a primary function independently of a secondary function of producing electricity. The first water reservoir or the second water reservoir may constitute a common body of water in the vicinity of ground level. The water reservoirs integrated in foundations of buildings may in particular cooperate with installations for air-conditioning or heating the buildings at the base of which they are constructed, or associated buildings. | 11-01-2012 |
