One of the Holy Grails of green power is hydroelectricity, and we've certainly seen our fair share
in that department. The newest guy on the scene is called Oyster, a collaborative effort between Queen's University in Belfast and Aquamarine Power Limited that sees something called an Oscillating Wave Surge Converter placed offshore (in depths around 10-12 meters). When moved by waves, the device's double acting pistons push seawater ashore via high pressure flow lines, where it is converted to power using tried and true hydroelectric generators. Since the hydroelectric plant is located onshore, it is accessible for maintenance 24-7. According to the company, peak power should be around 300-600 kw, depending on the unit's configuration and location. The first prototype is to be deployed off the coast of Orkney this summer, where we'll see if it can transform high tides and abnormal weather patterns into juice for your Xbox. One more pic for you after the break.
