Sway Wind Turbines Head For Open Water (green tech gazette)
25. February 2008
Norwegian wind turbine manufacturer Sway has decided to test its sea legs and put its product many miles offshore. The problem with wind turbines has been traditionally, the “not in my backyard” syndrome, where people may like the idea of them for generating renewable energy, but they don’t want to have to look at them.
Sway is addressing this “out of sight, out of mind” issue by developing wind turbines, that can be hauled many miles offshore into deep water, tether them there while sending the electricity back to shore via a 20 mile or so umbilical cable. Sway has just gotten an infusion of $30 million from Norwegian energy giant StatoilHydro to develop the offshore wind turbines.
The 275-foot tall wind turbines will be placed in deep water locations mainly in northern regions with sustainable winds. Below the floating turbines will be 300-ft of counterbalance along with a tether and ballast so that the structures don’t float away even during storms.
