Alaskan Wind Industries - Gaia Wind
Gaia-Wind turbines are developed and manufactured in Denmark. 
They incorporate more than 20 years of Danish wind industry design experience, which is the design basis for most commercial wind turbines in the market. Because of our modular manufacturing approach they are able to use components that are carefully selected to ensure the highest quality, maximum reliability and low maintenance requirements.
The Gaia-Wind turbine is in the "small wind turbine category" and has a peak rated output of 11kW. It produces an energy yield that is practical for supplying electricity to properties such as farms, large residences, offices, small businesses and public buildings where the primary goal is to reduce the amount of electricity imported rather than generate specifically for export. The turbine has been developed according to 'Danish design'; the design basis for most of the large commercial turbines used today. Like its bigger relatives, it has a slow rotational speed (61RPM) which remains constant regardless of the wind speed. It also incorporates many of the control and safety features found in larger utility-scale turbines.
The Gaia-Wind turbine is configured to give an optimal yield in moderate wind speed sites i.e. those with an annual average wind speed in the range of 4.5-7.5 m/s (10-12mph).

Online Performance Monitoring
You will also have real-time continual monitoring of the performance of your wind turbine through Gaia's unique web-based solution:
Safety and Control
The control system has been developed from the controllers of large turbines. It contains multiple sensors which continuously monitor the status and performance of the turbine. The internet connection for the controller means the wind turbine can be monitored online.You will also be able to view historical production overviews. With this particular function, a grey windy day becomes a bit more enjoyable when you can monitor the amount of energy being produced by your own wind turbine.

Certification
Gaia-Wind is the only small wind turbine manufacturer to have achieved the Danish HB Standards. These certify compliance with rigorous quality, safety and performance requirements.
Gaia-Wind is also participating in an independent testing program conducted by the National Renewable Energy Laboratory (NREL) in Colorado, where one of our turbines is undergoing five IEC-compliant tests. These tests have shown that this turbine not only performs like it is shown, but out performs at a lower rated wind speed of 21mph. NREL is also testing independently audited performance, noise, and duration data which we will add to our existing technical databases. Ongoing test results from NREL can be found by clicking here.
