Design a phone tower and hut that uses sustainable energy sources (e.g., solar panels, a small wind turbine, geothermal, etc.), a diesel generator system, and sodium metal halide (NaMx) battery to optimize green power used to run the station. The system should optimize available power in areas with either no/unreliable energy. The design should be feasible and use minimal resources and be reusable across developing regions.
The cell phone tower will run completely off of renewable energy and will have a backup diesel generator to power it if the renewable energy stored in the battery is depleted. The hut will shelter all of the equipment from any possible weather abuse.
This proved to be less then optimal for multiple reasons. In Chad there is no a surplus of
running water. There is, however, Lake Chad, which unfortunately has been gradually shrinking overtime
due to drought. Another issue is that this lake is located on the western side of the
country which limits where this cell phone tower can be built.
Due to research for wind statistics in Chad, it would prove to be ineffective to build Wind
Turbines as an optimal energy source. There is just not a sufficient enough amount of wind to
generate the minimal amount of power that is need to run the cell tower.
This proved to be the most optimal type of alternate energy to provide the power
needed to run the cell tower. The length of the day and amount of sun per year prove to
provide the solar panels with more then enough sunlight. Another important aspect is
due to how power is generated, there is no limitations of where these solar panels can
