The new turbine could be 70 feet higher than the old one with longer blades ! http://portsmouth.patch.com/announcements/win...
Wind Turbine Executive Session Meeting Feb 25
Posted by Bill Carson
February 23, 2013
The Town Council will be meeting in Executive Session on February 25 at 7 PM. The wind turbine agenda for that executive session meeting refers to possible investment of public funds where the premature disclosure would adversely affect the public interest.
The wind turbine executive session refers to two Rhode Island General Laws, RIGL 42-46-5 (a)(5) and RIGL 42-46-5 (a)(5) http://www.portsmouthri.com/Old%20Site%20File...

Public safety the first question or is it the wind turbine finances.
The Portsmouth Gearbox Failure Investigation October 14, 2012 on page twenty reveals the set back failure issues with the current wind turbine.
"The recommended ice throw calculation, 1.5 *(hub height + rotor diameter), indicates a minimum safe distance of 213 meters (699 feet). Per Figure 6, Highway 24, portions of the High School and several houses fall within this distance." http://www.portsmouthri.com/documents/Turbine...
Portsmouth had gear box issues. Today the wind industry has switched to a direct drive system. These new drive transmissions avoid the mechanical problems associated with a gearbox, but require extremely heavy and expensive generators.The direct drive gets Portsmouth involved with more new technology.
Monday night we'll find out if Portsmouth will use a single 2 megawatt wind turbine or larger in a public-private partnership ?
The first issue should be public safety,setbacks ,ice throw,shadow flicker,low frequency noise and a review of the setbacks to the town water tank.
