  •  Unintended Consequences / Unexpected Benefits (10+ / 0-)

    The Wave-Technology is not a new thing, and in the 1970's there were already several very promising studies done in the Netherlands. However, the fishing industry was less than sanguine on the topic of anything that could potentially put limitations on fishing operations.
    Now almost 40 years later, the result is that the North Sea and the North Atlantic are at the point of being dangerously overfished and depleted of commercially viable species.
    The unintended consequence of deploying Wave Power technology is that it effectively makes it impossible to fish with anything more elaborate than a line-and-hook system. You can forget about trough, float and drag-nets.
    The Unexpected benefit that rises out of this, is that it creates de-facto protected fish hatcheries and sanctuaries were presently depleted species may get a chance to recover to a certain extent.

      concluded that there would be only a benefit to sea life including mammals and cetaceans?

        the design I based my diary on happens to do without turbine blades so the environmental risk on sea life is likely lower, not sure if there is a definitive evaluation of this though.

        However, compared to the relative impact of nuclear, coal, gas...I think the benefit/risk ratio looks good on this one.

          In addition, Wavegen has continued to refine the turbine design through a programme of testing and modelling. An environmental assessment of the site and surrounding area is nearing completion. The work undertaken has been carried out by independent specialists so that SWEP can be designed with minimal effect on its surroundings. Work undertaken includes:

             * Landscape and visual assessments
             * On shore noise assessments
             * Marine habitats and ecology assessments
             * Archaeology studies
             * Transport and route access assessments

          They are designing with minimum effect in mind which one would expect.

          I appreciate your diary. May I suggest that you keep posting on this subject and please include the environmental assessments.

            Last April, ministers refused an application for 181 giant wind turbines at Barvas Moor on Lewis. The proposal had bitterly divided the island with the communities near Siadar being among those most strongly opposed.

            "We have always taken the view that the Outer Hebrides has a wide range of potential opportunities in the production, storage and use of renewable energy and wave power is certainly an exciting prospect for the future."

            Environmentalists were also positive. RSPB Scotland, which opposed the giant wind farm, welcomed the new wave energy farm.

              People don't like the sight of them, which, pardon me the pun, is teh short sightedness :P

                located in deeper water and over the horizon offer real potential.

                Stronger more consistent wind means more power generated and out of sight of land means less NIMBY opposition. Also deeper waters are sometimes further from bird migration routes.

                The technology to deploy turbines in deeper water isn't quite there yet but its coming, or so I read.

                There are land use and shore use conflicts. There is the damage to raptors and bats which then increases rodents and insects on the ground. But that's another issue.

                This wave action technology looks promising.

      related, it's no wonder the GOP and big business are trying to deny having destroyed both at the same time.

      So, let's do it.

      F#@k this Congress and the limos they rode in on!
