11.  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

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

14. 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

16.  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
