  1. Multidirectional Renewable Power Station James Marvin E-Design 100 Matt Quaglia Section 13 Daniel Rieman Alan Wisniewski

  2. Problem Statement • Certain regions around the world do not have reliable power grids which can support cell phone use or reception • Design an alternative energy telecom cell phone base station that can power a cell phone network, charging station, and limit the use of power diesel generator by incorporating GE’s new NaMx battery as a power storing system for the unit Mission Statement

  3. Requirements • Design an off-the-grid power source for a cell tower in a country with an unreliable power grid • Use NaMx battery to store excess energy • Output of constant 1.2-kW load • Cost under $500,000 Specifications • Use renewable power sources • Maximize power output of components • Use inexpensive materials which meet structural and insulation needs • Minimize the environmental footprint

  4. Location • Natural resources to support the telecom station • Economic potential • Ormara, Pakistan • Average wind speed: 6 -7 m/s • Average Daily Radiation for a Tilted Solar Panel: 6-6.5 Kwh/m^2/day • Along the Coast

  5. Design Features • Wind Turbine • Solar Array • Temperature Management • 20’ x 20’ base

  6. Wind Turbine • Funnels air • Receives 6 -7 m/s wind speed in Ormara • Utilizes air flow from multiple wind directions • Innovative turbine blade design maximizes potential for wind energy

  7. Wind Turbine Power Analysis

  8. Solar Array • Four 24”x48” GE CdTe Thin Film Solar Modules • Allows rotation through 360o • Rail System • Solar Array tracks sun across the sky to maximize hours of direct sunlight

  9. Sky Coverage of Solar Array Raises to 90o Closes to 0o

  10. Solar Array Power Analysis

  11. Temperature Management • Vents positioned along the base of the structure • Air flowing across the opening to the wind turbine creates an updraft • Concrete serves as a thermal mass which resists temperature exchanges between the inside and outside temperatures

  12. Energy Flow Chart

  13. Materials • Needs • Availability to builders • Provides structural support needed • Aids in insulation • Can be formed into different shapes • Keeps cost low • Steel reinforced concrete

  14. Cost • Initial Cost: $277,500 • Maintenance Cost over 15 years: $18,000 • Total Cost over 15 years: $303,00 • Initial Cost: $10,000 for a 30 kW generator • Operational: $3.20 per gallon of diesel fuel in 2010 • To run base station per year: $11,000 • Total Cost after 15 years: • $373,000 Our Building Diesel Generator

  15. Conclusion • Design meets all of the required specifications • Has a large safety factor greater than the 1.2 kW load • Design features innovative renewable energy sources • Wind funneling vertical turbine • Rotational and hydraulic solar panel • More cost efficient than a diesel generator over time • Payoff period is 12 years, and in 25 years diesel cost is double that of the MRPS design • Design is very versatile and can be used in many areas around the world
