Thanks for the link Bagpuss. Mick Sagrillo seems to have done his homework in the study of wind farming & makes a good bit of sense. After all he is owner of Michigan Wind & Sun, LTD & in being involved from that end of the industry I have to read what he says with that in mind, even still he does make sense & has made some very reasonable statements. His mention of the Altamont Pass Wind Farms near San Francisco & its bad siting in the local ecosystem is pretty much the same as Nantucket. Granted that's only one of the reasons that Altamont's faulted but it's one of the reasons that Cape people want a study and/or a report on.
The reef growth that MMario mentions might work better in deeper water, not in the area where they're considering which is 13 to 40 feet deep. The problem is that the owners want to place the turbines close in shore. On-shore they have to pay by either buying the land or renting it. Far off shore where the wind is better for their purposes is costlier to build & maintain & farther from electric & power source lines, again an additional cost. The placement in shore is their choice. Since when do private developers & builders tell the public where, how & why they will do as they please when they don't own the public resource they're planning on disturbing & when they haven't studied all the options. This type of technology used on our coastal waters isn't even covered by any capable authority. The US Army Corps of Engineers is the best so far by a law passed in the 1800's & that was given to them because of "Hazards to Navigation" which in this case goes way beyond.
How about a little bit of research & sudy & some org with the athority & intellegance to over see this from the debate process to the construction process to the stages of going on-line to the maintaince. So far there is no regulartory board (as in the nuclar industry) that I know of to yet govern this type of "off/in-shore" power industry
