  2. Agenda • The benefits of wind power • Wind power challenges • WindCube solution • Questions/Answers 2

  3. Wind Power: A Practical Solution • Renewable • Clean (no emissions) • Plentiful • Derived from free wind • Safe • Reliable 3

  4. Community Benefits

  5. Competitive Landscape 5

  6. Challenges for Wind Power • Distance between user and source • Height • Permitting issues • Cut-in speed • Scalability 6

  7. Advantages of the WindCube • Can be installed and operational quickly • Scalability (install one now and others later) • Easier to maintain than large wind turbines (all components easily accessible) • Unique design increases power generation • Smaller footprint • No land needed 7

  8. Fundamentals of the Technology • Power output increases rapidly with increase in wind velocity at the blades. • P = 0.5 (air density) (area) (air velocity)3 • WindCube amplification factor : 2 8

  9. WindCube Amplifies Air Velocity Creating Much More Power! Power Output With Shroud Power Generated (KW) Power Output Without Shroud Wind Speed (m/s and mph) 9

  10. WindCube Components • Shroud • Blades (5) • Nacelle • Generator • Gear Box • Brake System • Controls • Yaw Bearing • Base 10

  11. WindCube Technology Evolution • Inspired by: • R&D of Dr. David Spera, retired Exec. Dir. Wind Tunnel Program, NASA Research Ctr., Cleveland, OH • Marc Cironi – CEO Green Energy Technologies • John Fedor – Designer and manufacturer of specialty machines. • Blades designed by NREL (National Renewable Energy Lab) • Patent application # 60/871,135 filed in Dec. 2006 11

  12. Factors That Enhance the Value of WindCube • High average wind velocity • Consistent wind • Expensive local power supply • Locations far from the local power supply • Buildings that can support load • Users looking to enhance “Green” image 12

  13. WindCube Sample Applications • Urban Rooftops • Integration in New Construction • Exhaust Systems (e.g. Mining) • Grain Elevators • Rest Areas on Highway • Barge Ship Mounting • Off-shore Oil Rigs • Remote Locations

  14. Project Process • Application Feasibility • Local Wind Data • Present and projected power needs • Technical Feasibility • Structural Assessment • Environmental compliance • Economic Feasibility • Cost of installed WindCube • Investment and production incentives • Financing 14

  15. Moving Forward with WindCube • Find ideal market for cost competition (i.e., other green technologies or conventional) • Determine ideal delivery method • Supply • Design/Build • Power Purchase Agreement (PPA) • Decrease cost to market and install cost • Develop long-term financial analysis 15

  16. Questions and Answers • Now that we have identified a new solution to the challenges associated with wind power, what would you like to know? 16
