How Does a Wind Turbine Work? With GE’s New ecoROTR, Better than Ever

GE calls the experimental design the ecoROTR and the company started testing it here last month. If the experiments confirm wind tunnel data, the 20,000-pound dome could lead to larger and more efficient turbines for windy locations that are currently too hard to reach for the industry. “As far as I know, there’s nothing like this in the world,” Bowman says. “This could be a game changer.”

“When we crunched the numbers, we saw up to a 3 percent increase in performance,” Bowman says. “It doesn’t seem like much, but it’s potentially a lot when you apply the savings across an entire wind farm with dozens of turbines.”

The team attached the experimental dome, which is 60 feet in diameter, to a 1.7-megawatt wind turbine, one of GE’s most powerful machines, sitting on top of a 300-foot tower. Like the dome, the tower is also a prototype. Instead of traditional steel tubes, its “space-frame” design uses metal latticework wrapped in a polyester weave coat. The girders can be loaded inside shipping containers and onto ordinary trucks, and bolted together in places that were previously hard to reach.
