Problem Definition

• Due to the increasing cost of energy in the
  United States, Progressive Energy Inc. has
  decided to design an optimal wind turbine for use
  in homes instead of large businesses.

3
Constraints

• Dependant on only wind energy
• Harnessing other renewable sources adds cost and
  impracticality
• Self supporting Structure
• Decreases risks if failure
• Makes optimum performance of turbine

4
Constraints (cont)

• At least 30 feet high
• Wind more continuous and consistent
• Reduced dependency on other sources
• Turbines must generate electricity
• Marketable in Rural areas
• Iowa Average Wind speed is 11 mph
• More land available

5
Criteria

• Safety
• Ensure that adverse effects will not be caused
• Cost
• Expense to build
• Return Produced

• Appearance
• Visually Appealing
• Service
• Cost of maintenance and repair

Design 7 - Multiple Turbines
7
Design 6 -Tesla Turbine
Design 6 -Tesla Turbine

• Advantages
• Keeps efficiency at high wind speeds
• Fairly inexpensive
• Disadvantages
• Maintenance difficult
• More Prone to failure

8
Design 5 - Spiral Gutter

• Advantages
• Spiraled Blades
• Twisted Gutter
• Disadvantages
• Relative Instability
• Shorter Blades

9
Design 4 - Traditional Windmill

• Advantages
• Great for low wind speeds
• Time tested design
• Disadvantages
• Inefficient for medium and high speed winds
• More moving parts

10
Design 3 Industry Standard

• Advantages
• Very durable
• Very Safe
• Generates enormous amounts of electricity
• Disadvantages
• Very Expensive
• Hard to Maintain
• Noisy
• Visual Pollution

11
Design 2 - The Rotor

• Advantages
• Simple
• Rotates on Vertical Axis
• Disadvantages
• Low Power Output
• Large Forces on Rotor

12
Decision Matrix
13
Solution Vertical Spiral

• How it works
• Vertical Axis
• Works with any direction of wind
• What it made out of
• Base/Cap
• Blades
• Generator
• Support poles

14
Solution (cont)

• Advantages
• Withstands harsh weather
• Up to 50 more energy
• Cheap to construct
• Low maintenance
• Reliable
• Generator Located closer to ground

15
Conclusion

• Vertical Spiral best fits the criteria
• Vertical Spiral is a new, unique way to harness
  energy in rural areas
• A new futuristic look to wind turbines
