To the editor:
All wind turbines are not the same. The Boston Herald has made much of the noise problems with the older turbines in Falmouth whose rotational speed is controlled with a braking mechanism and gear box at their hubs. The Falmouth turbines did not employ the latest technology — even in 2006 when they were installed. We have learned from Falmouth.
Newer models such as the Hull 2 turbine, sited within 500-600 feet of homes, cause no such problems. The Hull 2 turbine relies on individual blade rotation (pitch) to control rotor speed, in addition to a braking cuff on the hub. Think of a fan in which each individual blade can rotate to make more or less of a breeze. This design is more efficient and quieter. There is less mechanical energy being converted into sound waves.
As a Salem Willows resident who potentially could be within earshot of the proposed turbine at Winter Island, I support an aesthetically beautiful turbine such as Hull 2 or the 1.6 MW turbine on Town Farm Road in Ipswich. Visit either of these turbines and hear for yourself.
Thankfully the most polluting of the fossil fuel era in Salem is coming to a close. Our energy must come from somewhere. I'm for having some of it come from a turbine that will generate clean renewable energy and consistent money for Salem. The sound of money rolling in, that's a sound I'd like to become accustomed to. KA CHING!
