Columbia Power a finalist in defense clean tech challenge

Columbia Power Technologies, an Oregon-based wave energy developer, has been chosen as one the finalists in the 2015 Defense Energy Technology Challenge.

The Challenge is part of the annual Asia Pacific Clean Energy Summit that will be held at the Hawaii Convention Center in Honolulu, Hawaii, on August 24-26, 2015.

Energy security and independence are two goals at the heart of the US Military’s investment in clean energy technologies and the Challenge identifies top defense-targeted clean energy solutions, according to Columbia Power.

The company is competing with their StingRAY wave energy device that uses the floats and spar that independently react to the shape of the passing ocean wave.

Each float is directly coupled by a drive shaft to its own rotary generator.

The two generators are located inside the nacelle near the top of the vertical spars.

As each float rotates, so does its generator, which creates electricity.
