WaveRoller : An Invention to Harness Underwater Wave Energy
It was a Eureka moment for Rauno Koivusaari, and he started to work on harnessing the powerful motion for generating underwater wave power.Now, fifteen years later, the EU is funding the WaveRoller invented by that former diver, with $4.4 million,for his company AW-Energy to build the first full scale demo of his invention.
Each one at full size weighs 20 tons and produces 300 KW.Each 20 ton WaveRoller “door” can be connected together in threes to make up a nearly 1 MW unit. Obviously you can make a modular farm of any size under the ocean of these three-packed units, so the output can be as much as you can build tons-worth of “doors”.
AW-Energy’s WaveRoller uses the roiling currents under the sea to make energy from the repetitive surge motion at the sea floor in what Koivusaari calls the surge zone. The kinetic energy produced is collected by a piston pump. This energy can be converted to electricity by a closed hydraulic system in combination with a hydraulic motor/generator system.This year the company will get the results of a full scale demo built off the coast of Portugal.
