Tidal turbines harness the power of the sea

Just as there were once 10 000 windmills across Europe, countless water mills helped power the rural economy and then the industrial revolution. And, just as reinforced plastics have supported the 21st century reincarnation of windmills as wind turbines, so they are beginning to contribute to the next likely large-scale commercial renewable energy source – water current power.

Great article on the turbines. I'm wondering what surface protection will be used on the composites to keep them free from barnacles and other sealife that wants to cling to the surface of the blades. Additionally they will need to be coated with a protectant that is not toxic to the marine environment. http://buildsitepro.com/
