The Wave Swell Energy (WSE) technology was recently tested comprehensively at the Australian Maritime College in Tasmania. The purpose was to quantify the effect of the company’s innovative new features when combined as part of a single holistic device. Earlier testing indicated each of these individual innovations led to an improvement in performance, the sum of which resulted in a combined 60% increase in output compared to other OWCs. When each innovation is incorporated into a combined device, however, the “whole is greater than the sum of the parts”. This was revealed during the latest testing, with a total increase in output of 97% over the previous best known OWC results. In other words, the WSE technology now produces more than double the electrical output of any other OWC device, when compared like for like. This result is fundamental to the cost competitiveness of the WSE technology.
