Hydrovolts Inc. new generation hydroelectricity

Seattle-based Hydrovolts Inc. has discovered a breakthrough new way of tapping our waterways for hydroelectricity without being quite so invasive. Instead of damming up mighty rivers or installing turbines in the middle of strong ocean currents, Hydrovolts has developed technology which can glean power from placid canals and other managed-flow waterways. Unlike conventional hydroelectricity, which generates power from water pressure, Hydrovolts' unique Flip-wing Turbine technology relies on kinetic energy generated from an ambient current. Power can even be developed from sewage treatment plants or food processors.
