A system and method for producing electrical energy utilizing horizontal axis water turbine assemblies, completely submerged and secured to a foundation on the seafloor beneath ocean surface waves in water depths corresponding to a nominal range of 1/30th to 1/10th of the wave lengths of prevailing waves. The water turbine assembly captures kinetic energy of vertically compressed elliptical orbital water particle motion having accentuated horizontal velocity for production of electrical power delivered to an onshore terminal. A group of multiple water turbine assemblies may be disposed at selected distances apart relative to one another and at selected distances from the coastline to form an array spanning a range of surface wave lengths in the shallow water depth to reduce temporal variability and collectively amplify and optimize the electrical power produced by the facility ashore.

Ocean wave kinetic energy conversion method and system

A Savonius rotor wind power generator system and method utilizes a large diameter rotor increased in sized to produce a proportional decrease of the rotation rate while the peripheral speed remains constant. The large diameter rotor operating at low rotation rates (less than 10 rpm) produces high torque, and electrical power is generated by means of a multiplicity of generators positioned around its periphery that are sized and have gear ratios matched to selectable ranges of wind speed to allow efficient automated electrical power generation over a range of wind speeds from about three meters per second to more than 40 meters per second. The arrangement, sizing, and control of these generators enable production of synchronous AC power generation over a much larger range of wind speeds than can be achieved with conventional horizontal axis turbines.

The invention is directed to a system and method for non-invasive pipeline inspection. According to one embodiment, the system includes a processor, an analyzer, and a wave launcher. The wave launcher is adapted to transmit an input wideband waveform having a selected input energy into the pipeline along a longitudinal axis, and to receive from the pipeline a reflected component of the input waveform having a reflected energy. The analyzer is adapted to generate the input waveform, and to receive the reflected component of the input waveform from the wave launcher. The processor is adapted to compare the input waveform with the reflected component of the input waveform to determine characteristics.
