ACOUSTIC PRODUCTION OF USEFUL WORK INCLUDING PROPULSION, LEVITATION AND GENERATION OF ELECTRICITY

摘要

Apparatuses and methods are disclosed for utilizing low frequency acoustic waves to extract energy from ambient air surrounding and object. The disclosed methods and apparatuses can be used for levitation of an object or to impose thrust on an object such as a rotor of an electrical generator, a passenger car, an aircraft, a marine vessel, a railroad car, etc. The disclosed techniques include attaching a low frequency sonic oscillator to a body to be moved or whose location is to be controlled. The oscillators create vacuums or low energy wells into which the objects are moved or levitated. Alternatively, the oscillators may be used to concentrate gas particles on a portion of a closed container, thereby causing a net force to be applied against the container wall and moving the container. The disclosed low frequency acoustic oscillators can also be used for levitation purposes.
