Several good articles. Things of interest I read were:
Waves along the US coast can produce 2.64 trillion kilowatt hours of electricity.
Oceans produce twice the power of wind.
Tidal energy converts 80% of the kinetic energy to electricity in comparison to 30% for coal.
Tidal and wave are much more expensive currently to develop than wind, but the energy production is much greater.
Canada has greater ability to produce tidal and wind power than almost everywhere else in the world. Think Bay of Fundy.
Four early feasibility studies for large-scale tidal power plants were conducted in the United States and Canada between 1924 and 1977 by the U.S. Power Commission, Nova Scotia Light and Power, and the U.S. and Canadian governments, respectively. All were focused on specific geographic locations around border areas between Maine and Canada. While conclusions varied regarding economic feasibility, they did not yield significant progress.
A large tidal barrage was built in La Rance, France in 1966 and still operates today with 240 megawatts (MW) of electricity generation capacity, the largest in the world until 2011, when an array with 254 MW capacity opened in South Korea.
In the past two decades, the industry has turned toward in-stream tidal energy generation, where a single device or groups (or arrays) of devices are placed within the tidal stream. The European Marine Energy Centre, established in 2003, is the world’s largest facility for testing and demonstrating wave and tidal technologies in real sea conditions. The facility, which has grid-connected test sites for larger prototypes and scale test sites for smaller devices, has facilitated testing of more tidal energy devices than any other site in the world.
I am continuing to read to see if the construction being used for wind turbines could ultimately be used for the facilities needed for waves and tidal power.
It also looks like the process needed to build wind turbines would also happen to build tidal and wave facilities- that is sonar mapping of the ocean floor.
If my father-in-law was still alive, I would be on the phone with him now because I am certain he would have researched this and could "dumb it down" for me. He would have been thrilled to get on the ground floor of designing and building anything new and challenging.
