| 20110131972 | Acoustic Turbine - A method and apparatus generates kinetic and electrical energy using sound waves and is believed to be particularly useful in high efficiency motors and electrical generators. In particular, the method and apparatus uses sound waves as a catalyst to convert ambient heat energy into kinetic and/or electrical energy. In one embodiment, sound waves at particular frequencies are propagated across one side of a plate or other barrier element, causing flow of fluid (e.g. air) across the surface of the plate which, in turn, causes a reduction in the ambient fluid (air) pressure near the surface of the plate. The difference in fluid pressure on opposite sides of the plate results in net positive thrust on the plate, thereby causing movement of the plate. This movement can be harnessed using, for example, a windmill type of rotor and stator arrangement to generate useful kinetic and electrical energy. | 06-09-2011 |
