摘要： A method for generating acoustic waves under water includes actuating first and second pistons with an actuator system provided inside an enclosure of a source element, to generate a wave having a first frequency, and actuating the first and second pistons with a pressure mechanism attached to the enclosure, to control a pressure of a fluid inside the enclosure such that a pressure of the fluid is substantially equal to an ambient pressure of the enclosure. The enclosure has first and second openings and the first and second pistons are configured to close the first and second openings.

摘要： An air, fuel, and water mixture is injected into a resonance chamber forming micro-packets. The micro-packets are ignited forming micro-explosions in a combustion chamber containing a central resonance chamber creating a standing wave interfering with a standing wave in the resonance chamber generating the micro-packets. The interfering waves are in phase aiding in the disassociation of molecules, including hydrogen and oxygen, in the air, fuel and water mixture. Efficient combustion is achieved with a nearly zero carbon emissions. The heat generated from the combustion may be used to produce work by any conventional device, such as a steam engine or turbine or generate heat for a building.
