The turbines

The turbines seen from Lights Beach, 3.5km west of the windfarm. Wind velocity increases as it moves up the cliffs, and the turbines benefit from this enhanced windspeed.

Cutaway of a typical direct-drive wind turbine. These machines have no gearbox, which is a source of heat and energy losses through friction, and was a common failpoint in earlier machines. —netzeroguide.com
