WaveSwimmer attaches to the ocean floor via cables and cable tension mechanisms. The mechanisms can keep WaveSwimmer at the optimal height during tides and as sea levels rise. WaveSwimmer could also be pulled down beneath the waves in order to protect it from being thrown around during violent storms. Designed to not be an eyesore, WaveSwimmer could be located close to the shore, with minimal visual impact.
The available energy in ocean waves is tremendous. According to the US Energy Information Administration (EIA.gov), the theoretical annual energy potential of ocean waves off the coast of the United States is about 2.64 trillion kilowatthours, or roughly 64% of all US utility-scale energy generation. Due to this, ocean wave energy could produce much, if not all, of our country's energy needs, especially with conservation.
