Key Dynamic: Leverages Current Platform Design; Upgrade Annual Energy Production! Low Wind – 8ft Diameter Rotor

• Doubles Swept Area from 80 Sq. Ft to 160 Sq. Ft. • Larger Airfoils and Struts• Upgraded Generator: Tighter Windings to Get Higher Voltage• New Diameter Will Lower Rotor RPMs and Provide More Torque• Preliminary Analysis: 4,000 kWh’s in a Class 2 Wind ; 5,000 kWh’s in a Class 3 Wind• Potential Upgrade Solution for Current 1.2kW; Opens New Market in Class 2 Wind

3kW• Preliminary Rotor Analysis is Complete• Design for New Generator and Inverter are in Process• New Foundation, Pole, and Bearings Require Further Analysis• People are Willing to Pay for Solution to Power 80 – 100% of Annual Electrical Usage!
