Setback for Oregon coast wave power project

REEDSPORT, Ore. (AP) — The company planning a wave energy installation off Reedsport won't have its first buoy in the water this year as planned.
Ocean Power Technologies says it managed to put one of three anchors in place, but the remaining two anchors will spend the winter in Reedsport while the power generation buoy is stored in Portland.
Marketing director Greg Lennon told The World the company encountered a number of challenges, mainly the weather.
The Pennington, N.J., company eventually plans to have 10 buoys about 3 miles off Reedsport. They would use the motion of waves to generate enough electricity for about 1,000 homes.

So there will be three navigational hazards to supply electricity for 1000 homes.  I also wonder if this is a worth while project once the cost of the equipment, instillation and maintenance and how long the buoys will last before replacement are taken into consideration. Then I ask myself ..WHY?  Oregon is blessed to have an abundance of inexpensive Hydro power, and these alternate sources are not necessary.. Why again are we doing this wave project?
Keep us posted KVAL..I want to know if these things are waste of money...it seems like a good idea
