A British firm called quietrevolution
will begin installing 6-kilowatt vertical-axis wind turbines this year. The turbines are much smaller than typical designs, and can be installed discreetly in urban and suburban areas. The quietrevolution design is also "virtually silent and vibration free," designed for maximum reliability and minimal maintenance.
The quietrevolution design solves some of the problems typically associated with wind turbines... namely that they require lots of open space to operate, and are accused of being eyesores.
