A new dome-shaped add-on to wind turbines may help them generate more power and bring construction costs down in the process. GE has installed its experimental new cleantech, called the EcoROTR, on a wind turbine in the California desert outside the city of Tehachapi.
GE says its â€œUFO-looking technologyâ€ (the companyâ€™s words) will increase the amount of electricity generated by a turbine itâ€™s installed on by 3 percent. More importantly, perhaps, it will allow giant wind turbines to be built with significantly shorter blades, and cut costs by up to 25 percent.
Itâ€™s still an experimental project in the R&D stages, but GE assures me that it will be cost-effective, and holds major promise for commercial energy production. Plus, the company is right; the thing sits squarely in the tradition of space-age tech
