Supporters of the MAV floating wind turbines plan have yet to take seriously (let alone discuss) the predicted effects of the project on the hydrodynamics of the Gulf of Maine off Penobscot Bay.

Yet the scientific consensus is that the wind shadow of reduced wind velocity (-25%) immediately downwind of an ocean windbturbine continues well into the water column below. The reduced velocity of those waters, compared to the water outside the windfarm's shadow, results in creation of an upwelling of waters from the lower water column to the surface.
As Norwegian expert Goran Brostrom, who's familiar with Maine's offshore wind plans, puts it, a wind decrease of 25% corresponds to a 50% decrease in wind stress at the surface. By the time 20 years have blown past, the two floating turbines chugging away will have earned hundreds of million dollars or more selling electricity. This money will then be used to set up more of them further offshore Focusing on whether the project saves carbon providing provide electricity for Monheganians

I don't like the pinwheel design as it is too noisy and more maintenance costs compared to VAWT. I never saw a reason to put them at sea except that they were out of hearing range of people. VAWTS are silent so put them anywhere the wind blows.
