powAIR Sail

Vertical Axis Wind Turbine

powAIR Sail is a revolutionary turbine is a vertical axis windmill that employs a patent pending axial flux generator. With its innovative design and features, it converts the kinetic energy natural wind flow into electricity for immediate use. Our exclusive vertical axis windmill is the most efficient on the market, boasting the lowest startup winds speeds available.

Vertical Axis Windmill Design

The advantages of our vertical axis windmill include:

• Utilizes wind from all directions, eliminating the need to constantly reorient the machine to the direction of the wind and therefore increasing efficiency
• The sails are designed with aerodynamic geometry that catch wind on one side of the sail and slice through on the other side
• Starts up speeds are only 1-4 mph
• Spins at low rpm’s, which reduces harmonic vibration
• Light weight design, starting at under 300 lbs, making installation on all types of structures possible
• Ability to harness turbulent winds, making it possible to deploy in urban areas and areas of manmade kinetic energy, such as airports
• The life expectancy of the unit is over 20 years with proper maintenance

Axial Flux Generator

This patent pending generator ensures peak efficiency at low wind speeds. This generator was designed to be utilized in conjunction our vertical axis wind turbine, where energy from the turbine is delivered directly to the axial flux generator at the base of the unit. The use of an axial flux generator eliminates the need for gears and pulleys to increase the RPM’s, thereby producing torque at low RPM’s. Our patent pending generator has many benefits that include:

• Most efficient generator available through all wind conditions
• Able to generate continuous energy from winds as low as 1-4 mph
• The use of axial flux generator eliminates the need for gears and pulley, which decreases the number of parts that can fail
• Having the generator at the base reduces the need for a large tower, provides the unit is structurally sound, and makes servicing the unit much easier
• With the unit running on low RPM’s, the life of the generator is enhanced by reducing the amount of ware and harmonic vibrations
