Multidirectional Renewable Power Station
James Marvin E-Design 100Matt Quaglia Section 13Daniel RiemanAlan Wisniewski
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
Problem Statement
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
Requirements
Specifications Use renewable power sources Maximize power output of components Use inexpensive materials which meet
structural and insulation needs Minimize the environmental footprint

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

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
