We have not covered wave power for a while and the reason is pretty apparent when you read this recent item. A giant wind turbine in the same location can produce twice the power of the planned $60 million investment and it will not sink. In the open seas, the intermittent aspect of the winds is better described as intermittently missing. We have already learned to live with that.
Wave power is in the early engineering development stage. It can surely be improved.. However, gigantism is not likely a benefit as in wind power. The buoys have to generate power over a wide range of wave generated power strokes. There will likely be modalities in which they will perform poorly. So wind is not the only power source that suffers from intermittent drops in production.
Exposure to the sea itself is hardly minor. The devices will have a life span comparable to an ordinary ship whereas a wind turbine is exposed only in its static foundation structure. We may eventually go for floating structures but with so much available shallow coast it is rather pointless.
The energy itself is quite real but the ability to tap it is a very expensive exercise in marine engineering.
