XCT-1
The kinetic energy in river, tidal and ocean currents is an abundant resource that could support a potential $20 billion global market. However, an estimated 80% or more of this potential is locked up in relatively slow-moving waters where currents flow at 2 m/s or less for most of the year. The central idea of the LPS “cross-cutting” (XCT) current energy conversion device is to efficiently convert modest velocity flows into electrical power. The XCT trades swept area for localized velocity, by moving small, inexpensive turbines through the water rapidly. It eliminates gearboxes. Intended to fun fully flooded, it is anticipated to reduce maintenance costs. The estimated cut-in speed is 0.35 m/s per flume tests conducted in 2020 – to be confirmed in open water
