The Nature Conservancy Installs Bird Safe Wind Power
SheerWind's wind power funnel is generating on bird sanctuary, Palmyra Atoll
MINNEAPOLIS, July 21, 2015 -- The Nature Conservancy has completed its first phase of installation of SheerWind's INVELOX funnel-based wind power technology. Because Palmyra is home to a national wildlife refuge and more than a million nesting seabirds, conventional wind turbines were not an option due to the risk of bird strikes. What's more, the low wind speeds on the island would provide little to no energy production with traditional turbines.
The Conservancy turned to the Minnesota firm SheerWind to design the system resembling an hourglass turned on its side. Extending 83 feet horizontally with a big wind scoop at one end, an exhaust on the other, a Venturi section in the middle increases wind speed potentially three to six times. Nets over the intake and enclosed blades keep it bird friendly. The first phase of the installation includes a single turbine inside the Venturi, allowing for two additional to be installed in the near future.
The first phase of the INVELOX project is successfully charging batteries at night and on cloudy days to supplement the photovoltaic system also installed on Palmyra.
"With a goal to reduce dependence on fossil fuels, SheerWind's INVELOX was the only viable solution for the multiple restrictions including height, wind speeds, and of course bird populations. This solution works and helped bring the goal to reduce fossil fuel use a reality," said The Nature Conservancy's David Sellers, who is the driving force behind the design solution and details of the INVELOX installation.
Palmyra Atoll is located 1,000 miles south of Hawaii in the vast equatorial Pacific, and hosts spectacular coral reef and tropical island ecosystems, but is a challenge for humans to inhabit. There are no commercial flights to this remote outpost, which is co-owned and managed as a scientific research station and national wildlife refuge by The Nature Conservancy and The U.S. Fish and Wildlife Service. Until the recent installation of wind and solar, Palmyra was run on diesel fuel generators. These installations reduced its dependence on fossil fuels by 95%.
"We are grateful for David Sellers and The Nature Conservancy's commitment to installing the first commercial system in an extremely challenging location. We are pleased we were able to contribute to this important achievement and hope this is an example to be duplicated globally," said Dr. Daryoush Allaei, founder and CTO of SheerWind.
SheerWind has developed a new-aged wind power generation system that produces more electrical energy efficiency at roughly 75 percent of the cost of traditional turbines. The technology is safe for humans and wildlife, requires less maintenance than conventional wind systems, and produces more electricity per dollar invested than conventional systems. The funnel-driven system captures the wind and brings it to ground-level turbines and blades for safer, easier and cheaper operation and maintenance.
