The first major advancement in wind turbine design since 1931, the TR-10 represents a new sub-class of wind turbine and a significant evolution in wind energy systems technology.  A simple mechanical device that performs complex physical functions based on helicopter rotor design theory.  U. S. Patent Pending, the TR-10 VAWT introduces a new direction for wind energy R & D.

(Vertical Axis Wind Turbines)

• Much quieter
• Bird friendly
• Easier to place aesthetically
• Constant blade exposure efficiency
• Lower RPM/longer bearing life
• No wire twisting or power transfer brushes
• Not damaged by variable wind conditions
• Not dependent on exotic airfoil designs
• Not dependent on non-standard manufacturing
• Potentially lower $/watt
