Wave Energy Converter - why not more of these?
(OP)
Pelamis Wave Energy Converter generating electricity into the Portuguese grid off the coast of Aguçadoura, Portugal, October 2008. Can anyone tell me why we do not do more of these projects?

For another, it's got a lot of mechanical parts moving in seawater continuously, and just as many popping in and out of the water, which is probably worse.
For another, it's going to attract idiots, who will inevitably be maimed in one of the many pinch points.
The idiots will arrive in their boats, sometimes the hard way, e.g. at night, steering between the navigation lights at full speed. Don't tell me it won't happen; it happens to submarines, which have lights on the sail and the fin, and non- navigable water between them.

Another thing to think about is the energy density, by which I mean the size of machine you need to get a certain power output.
The sea is a pretty tough environment.
You often need a rectifier which is either inefficient or expensive.
Finally you are generating power in the wrong place, so you have transmission losses.
I think tidal barrage or tidal current systems make far more sense.

Gotta disagree with it being in the wrong place. Population centers tend to lie along the coasts.
As far as energy density, like wind it is a nice concentrated form of solar; using the whole area of the ocean for collection. It is more steady and dispatchable than wind, since there are existing bouys to let you know what is coming. Best for winter peaking areas.

I'm sure the skippers will be able to avoid well marked and charted wave parks. The largest concerns are coming from crab fishermen and surfers.

Perhaps we can eventually reduce the number of petroleum carrying tankers with technologies like the one under discussion.

Do you have any good references on what is the cost/MW for these renewable energy sources. Not only asset installation, but also life cycle cost. I think that the incinerator/generators need "costly" garbage, no? (Meaning that they do not burn just anything).
Thank you for the post.
