 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

 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  Use renewable power sources  Maximize power output of components  Use inexpensive materials which meet structural and insulation needs  Minimize the environmental footprint

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

 Wind Turbine  Solar Array  Temperature Management  20’ x 20’ base

 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

 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

 Needs ◦ Availability to builders ◦ Provides structural support needed ◦ Aids in insulation ◦ Can be formed into different shapes ◦ Keeps cost low  Steel reinforced concrete

Our BuildingDiesel Generator  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

 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
