2. BACKGROUND
Electricity is a major determinant of a country’s economic prosperity.
Uganda has hydrological and other renewable energy resources, yet
there is widespread energy poverty throughout the country.
Government’s attempt to ensure energy easy access of energy to most
Ugandans has not yielded much fruits.
High charges on electricity units make it expensive to most people.
Climatic change do affect hydropower generation.
The prolonged hours of power cuts and rapidly growing population
raises demand for energy, time after time.
Alternative power generation methods need to come into play.

3. PROBLEM STATEMENT
Energy usage is at all-time high and as nonrenewable energy
such as fossil fuels dwindle, alternatives need to be considered. A
mechanical footstep power generator provides this alternative as
it is a renewable source of energy that is passively human
powered.

4. OBJECTIVES
MAIN OBJECTIVE
• To develop a cost effective footstep power generator, which in
turn helps to reduce energy poverty in Uganda.
SPECIFIC OBJECTIVES
To design a footstep power generator.
To simulate a footstep power generator.
To analyze the effectiveness of a footstep power generator.

5. RESEARCH QUESTIONS
To what extent has the exploitation of nonrenewable sources of
energy reduced the energy poverty in Uganda?
To what extent has the exploitation of natural resources in search
for energy affected the environment?
How will the adoption of a footstep power generator reduce the
energy poverty in Uganda?
How can the energy tapped be stored for use?

6. JUSTIFICATION OF THE STUDY
Many households have experienced prolonged hours of power cuts,
most especially in rural areas where the demand for electricity
outweighs the increase in electricity generation due to the rapid
population growth.
High charges on electricity bill make it expensive.
This project will provide cheap and affordable electricity that will
solve the problem of frequent power cuts.

7. SIGNIFICANCE OF THE STUDY
This project is to develop a new source of renewable energy with
low-cost budget.
Footstep power generation method is a simple, since it involves
just stepping which do not require any special training.

8. SCOPE AND LIMITATION OF THE STUDY
This project only seek to harness the energy generated by the
impact of the foot on the floor during the gait cycle.
This project is limited to electricity generation for domestic
application using rack and pinion arrangement along with the
gears, shaft, battery and dynamo.

9. METHODOLOGY
Data was obtained mainly through research and literature review
of related projects.
Simulation was done using solid works.
Results were obtained through analysis of the simulation.

footstep power generator
Energy stored in flywheel
= 23.58watts
The result therefore
exceeded the theoretical
results on the table to the
left.
Theoretical power
• The simulated model can
therefore be used to generate
power for lighting purposes.

13. CONCLUSIONS & RECOMMENDATIONS
Conclusions
Conversion is considered
renewable energy.
Energy is generated by
making use of flywheel.
With the simulation and
experimental analysis of
work of previous researchers,
footstep power generator is a
reliable source of energy.
Recommendations
Use of a ratchet.
Modify the system to be used
in a staircase.
Modify the system to handle
the weight of moving
vehicles.
