Rogue River Wind and Portland State University Maseeh College of Engineering and Computer Science, have joined forces to optimize power generation from a high efficiency wind turbine suitable for rooftop mounting. Pictured here, this twelve foot, self indexing turbine can produce 3Kw at 15mph winds. The turbine is unaffected by air turbulence that can adversely affect most open bladed designs allowing rooftop mounting without tall towers. 
The turbine is silent, vibration free and can be screened to prevent harm to birds and other wildlife. The turbine can be used in both rural and urban locations with good wind resource.
The high bandwidth generator is housed in the outer rim of the fan and power output can reach double digits. PSU will be assisting in the design and optimization of the production level generator. Testing will also be conducted by PSU and is expected to begin this fall once testing protocols are established.
Production costs are yet to be determined however I can tell you that the turbine will be highly competitive with systems capable of achieving like power output.
Specs will be posted here and on Rogue River Wind shortly
Re; Rogue River Wind/PSU project;
Do you have any idea what kind of price the units(Wind Turbines) might sell for? I see from a previous posting they might be available sometime next spring. I there any kind of spec. sheet available?
Thanks,
Night Train
Hmmm, let me see…. Spring
Wow, this sounds terrific. When will theses be on the market?
