Each VAWT offers a high survival wind speed capability and towers from the standard 5.5 meters to 11 meters in height- capable of being lowered to 90 degrees angle when incorporating an innovative hydraulic system. These windmills are considered lift-type, with several patents registered in countries throughout the world. In addition, the wind turbine and wind controller are signed off to CSA standards enabling on-grid connections in Canada. Our basic models include the 1KW, 3KW, 5KW, 10KW, with the 50KW and 500KW in development.
The innovative design follows the principle of flight, where the blades generate lift, causing rotation, thus generating electricity.
One impressive aspect is the “active real-time pitch attack angle regulation” initially designed by the Talos engineers in 2005. In 2006, the first international patent was issued to this technology, followed by a US patent issuance in 2010. Once the wind speed begins to approach 12 m/s, the five blades start to change their angle of attack as centrifugal force increases. This angle range 0 -16 degrees is controlled by ten springs, causing the windmill to slow in the more substantial winds and to continue to generate electricity.
Once this passive braking system reaches complete deflection and max voltage, a secondary automatic brake is activated.
