There have been several european companies that have built wave powered generators however it faces many challanges including corrosion, and high tides. I'm sure I'm missing alot of info but it is an intriguing idea.
All one ever hears about is how screwed up the ocean is...how about this for a change?!

The floor of the Gulf of Mexico off the coast of Alabama is primarily flat and sandy with no natural reefs or structures to break the terrain (just like Monterey Bay from Capitola to Sand City). However, in the aquatic environment, almost any material that adds topographical relief will attract fish and increase catch rates. This concept has been applied extensively in coastal Alabama with the placement of more than 14,000 artificial reefs. AAES research is helping define the uses and implications of these reefs and how and why they affect fish populations…all (studies) suggest that the artificial reef system off Alabama has an important production component (as opposed to being just a fish attracting device).
according to Jack Spey, Reef Coordinator for Florida's Okaloosa County, "Man doesn't create artificial reefs -- Mother Nature does. Man can only place vertical structures offshore, which are needed in the Gulf of Mexico so that Mother Nature can take over, and organisms can attach and prosper.
"By placing artificial reefs, man is increasing the capacity of nature to create habitat. Nature is then able to procreate at an increased rate," said Spey.
My ultimate dream for our State…Fishing reefs increase bio-density, the ocean is a 24/7/365 energy machine and Coastal California has erosion problems…the highest engineering prize ever should go to brains behind a wave blunting fish reef that produces renewable electricity from wave energy.
Wind may blow, sun may shine, but the Ocean is eroding our coasts 24/7/365 with wave energy that could (long term) solve three BIG problems.
They put turbines in the Hudson River recently and they provide enough power to run a local grocery store on the river bank. They had some problems initially, but got them worked out. It could work further up and down the river and in other locations as well, but the companies need funding to get them going and that is always in short supply. We seem to have plenty of money for leveraged buyouts, hedge funds and sub prime mortgages, but never enough for innovative new companies.
