Wave Energy in the North Sea


An open flow of water, be it a current or wave, will choose the path of lowest resistance. This makes it hard to move along in the same direction as the flow and extract a good deal of energy out of it. The Slow Mill has a unique system of blades that changes the direction of flow temporarily to optimise the angle of attack, enabling more energy to be extracted from the current. As shown in the lab tests at TUD, high resistance to open flow and high efficiency can be observed in the models. The prototype will be made from ffibreglass composites that have no corrosion nor fatigue and thus a long lifetime without much maintenance. It's also light weight so that the machine is sensitive to moderate forces as well.
