Problem Statement • Third world nations often lack a reliable grid where the majority of the population is living under the poverty line. • Hence, we need to find a design that will create a self-sustaining operating system for a cell phone tower to be placed in a location with unreliable access to the mobile network.
Our Mission: • Our mission is to design a sustainable energy system for a region without access to the grid which will provide reliable power to a cell phone tower that operates with minimal costs and maximum profit.
Southeast Kenya • Economy: • Finance • Investment • Tourism • Agriculture flat landscape • Politics: • Very politically stable compared to other African nations • Mombasa’s Landscape • Flat • Very little rain • Rarely Windy • Sunlight • Customers • Potential network of 326,080 mobile subscribers • Phone Service Providers: • Zain and Safaricom
Wind Power • Propeller generates power from wind • Effective over time, but not consistent from day to day due to fluctuating wind speeds in Kenya.
Hydroelectric Power • Propeller is placed underwater in a river to generate electricity reliably and consistently. • Disadvantage: not many rivers in Tanzania, so not very practical.
Diesel Power • A reliable source of energy, but uses fuel to run it which is not a renewable resource.
Solar Power • Solar panels generate enough power to run the station and store extra energy into a battery for use at night or on overcast days.
Our Selection: • Power the tower primarily with solar energy. • Store extra solar power in battery. • Use a diesel generator as a back-up.
System Features • Main Hut: • Cinder block walls • Wooden framed roof • Six 5’ by 4’ solar panels on roof • GE’s Durathon battery • Base Transmitter system • Air conditioning • Lighting system • Cell Phone Tower: • Guyed tower
Team Seven would like to thank GE for sponsoring this cell phone tower design project.
