Electricity generator operating from fluid flow - uses oscillatory system and has mechanical resonators amplifying oscillation fed to oscillatory alternator

摘要

The oscillatory system uses fluid and/or solid masses and mechanical resonators. The system is subjected to alternate excitations amplified by the mechanical resonators and transmitted to an oscillating electrical alternator. The system may exhibit circular or longitudinal oscillation. The generator may be driven by a natural water flow and have a barrier plate followed by an initial turbine stage, an oscillatory rotor, a resonator and an oscillating electrical alternator, all of which are housed in a water-tight unit. Alternatively the electricity generator (28) is used in a vehicle in combination with a starting battery (32) and an electric motor (30) directly driving the wheels (31). The generator in this case has a number of oscillating pistons coupled to an oscillating linear resonator using a series of masses and springs, with the alternator employing piezo-electric elements. The generator is used to conserve fuel or to allow small hydraulic flows to be utilised.
