Group 7

Needs Expressed

No grid or unreliable grid – need for an alternate source of energy

Protection for the electronics Positive social implications in the chosen country

Requirements in Product Design Alternate energy source 1.2 kW load, BTS DC Equipment operates at -48 VDC

Incorporation of sodium metal halide batteries for energy storage

Hut equipment to protect electronics

Semi-presidential republic Official language- Swahili, English Total GDP(PPP)- $65.059 billion Climate- tropical Hot and humid near the coast Dry inland to the North and Northeast

Kenya

Market-based economy Tourism accounts for 63% of income. Agriculture accounts for 24% of income. Industry such as food production accounts

for 14% of income. The majority of Kenya’s energy comes from

hydroelectric dams along the Tana River. The rest of their energy comes from

petroleum plants, geothermal plants and some is imported from Uganda.

Kenyan Income and Energy

Why is cell phone service relevant?◦ Kenya has a goal to become a technological society.◦ In order to do this, availability of cell phone signal is key.

Why use an alternative energy source?◦ The majority of Kenya’s electricity comes from alternative

energy sources.◦ Nonrenewable resources (oil and natural gas) are rare in

Kenya – would need to be imported. What would be the effects on Kenyan society?

◦ Bring technological advances into a country that is continuing to grow.

◦ Would not greatly alter the current lifestyle of Kenyan citizens.

High cost to implement

Low cost to maintain Only 10-23%

efficient

Geothermal Power

Creates power by using flowing water.

Expensive to implement

Low maintenance costs

Creates high amounts of power

Hydroelectric Power

Only takes up a small plot of land for base of turbine

Moderately Inexpensive

Available in a range of sizes

However, wind is not always available

Wind Power

Low startup cost Low maintenance

cost Panels can last a

long time However, sunlight

is not always available

Solar Power

Mini wind turbines combined with solar arrays

Add a large amount of reliability to the system◦ In such weather conditions

where sunlight is not available, wind often is

Wind greatly improves the effectiveness of off-the-grid systems, especially in winter

Cost efficient

Wind and Solar Combination

Energy Flow Chart

Implement GE Solar Panels Solar panel will be set at an 85˚ angle

◦ Optimum angle to attract the most sunlight, especially during the winter months

For the sake of cost efficiency, the panel will remain at the 85˚ angle throughout the year◦ Will keep maintenance costs low

Solar Component

System will incorporate a smaller wind turbine model◦ Minimize costs◦ Minimize wasted energy
