The document summarizes a student project to design and build a solar Stirling engine with solar tracker. It includes sections on background, methodology, components, preliminary results showing 520 RPM generation, features such as being environmentally friendly and cheap electricity production, applications, and a conclusion that increasing the size could generate up to 5kw of electricity at low cost. It is presented by 6 students to their internal and external advisors.

3. Introduction
Global warming has increased the demand
for green energy production by renewable
sources such as solar power.
The power shortage in Pakistan increasing
day by day, and there is no short term and
long term plan available to overcome this
problem in this scenario.
Technology is vastly being cultured and
embedded in our day-to-day activities.
To overcome this situation, solar energy is
the most efficient way to generate
electricity, but solar panels are much
expensive and our country is also facing
financial crisis now-a-days.
Best way to generate electricity is through
heat energy, and our project depends on the
heat energy. The Solar Stirling Engine that
we are designing is the optimum and
convenient solution for power generation.
4. Background
The Stirling engine was invented by Robert
Stirling in1816. At that time, the Stirling
engines were recognized as a safe engine
that could not explode like steam engines.
But the Stirling engine had been made a
poor production, in comparison to Otto
engine and Diesel engine.
The Stirling engine had been started to
develop rapidly in 1973.
Still more, energy and environment problems
have become one of the most important
social problems at present.
Then the Stirling engine is being noticed
now. The reasons are
High thermal efficiency
A great variety of the fuel
Low emission and low pollution
5. Methodology
The basic idea is to convert heat energy into
mechanical energy and then mechanical
energy into electrical energy. And to utilize
more and more sun energy, the solar tracker
can makes our work easy.
11. Features
The features of our project are given below:
Environment friendly
Cheap electricity generation
Less maintenance
Digital display
More reflection of sunlight due to shiny
aluminum sheets
Light weight due to aluminum
Effective and efficient
Easy to implement
More utilization of sunlight due to the solar
tracker
12. Application
The applications of our project are given
below:
Refineries
Domestic use
Commercial buildings
Bill Boards
Traffic signals
Street lights
Space research
13. Time and Cost
analysis
This entire project has a maximum
completion period of about 7 to 8 months.
The purchasing of the required necessities
and the designing of the hardware model
have been completed during the first few
weeks of the project initiation.
Placement of orders for the implementation
and manufacturing of engine’s design
Manufacturing period of engine – 1 month
In the mid of November, the project will be in
its final phase of completion and will almost
be ready to be presented to the final year
committee with the documentation. We
therefore hope to complete our entire project
latest by the end of November.
The entire project is liable to change but the
estimated project cost is around Rs. 70, 000
– 100, 000, depending on the equipment
cost fluctuation and the cost spent in testing
and implementation.
14. Conclusion
After discussing our project we concluded
that if we increase the size of the parabolic
surface and placing the powerful Stirling
Engine, we can easily increase our
generating capacity upto 5kw.
Hence it can be the milestone for generating
electricity at lower cost in our beloved
country Pakistan.
