Ocean Power

Here is a post from ecogeek showing two different products which develop energy from either wave or tidal processes. I am not sure how cost effective these types of technologies are, but there should be a tremendous future energy source for many coastal communities. I love these types of technologies, but I do not have enough expertise in this area to make an intelligent prediction on when (or if) they will be competitive energy options. It seems like an intelligent energy policy would be able to take advantage of local and regional environmental conditions such as abundant wind, geo-thermal, or solar energy. In some areas you would think that wave and tidal energy would be one such option.
