Wave Power is one of our largest renewable energy sources, but until very recently we have lacked the technologies to harness such raw energy. There are now thousands of patents describing potential wave energy devices, but very few have been translated into working prototypes, and even less in to devices with the survivability needed. However, as the feed in tariffs for energy derived from marine sources are increased by certain governments, many new designs are sure to leave the drawing board or CAD file - only time will tell which ones will form the backbone of the future industry.
