2. INTRODUCTION
This project discusses the design and development
of a hybrid micro thermo-electric and Stirling
engine for power generation
This design of power generation is combination
between two types of source that are the thermo-
electric and Stirling engine.
The purpose of this project is the development of
a micro thermo-electric and Stirling engine that
capable of operating on a variety of heat sources,
specifically on waste heat. 2
3. PROBLEM STATEMENT
3
Efficiency of the Stirling engine drops if the
temperature difference between the hot and
cold ends decreases.
Efficiency of the thermoelectric drops if the
temperature difference between the hot and
cold ends decreases.
4. OBJECTIVE PROJECT
To design the hybrid of micro
thermoelectric and Stirling engine for
power generation.
To optimize the output power of the
hybrid system.

Design and a prototype
implementation of a maximum
power point tracker (MPPT) for a
thermoelectric (TE) module aiming
to improve energy conversion
efficiency in battery charging. This
system uses TE devices that
directly convert heat energy from a

Title Description Citation
Modelling of
thermoelectric
devices for electric
power generation
The steam-Rankine cycle is the
principle exploited for producing
electric power from high
temperature fluid streams. Gas and
steam cogeneration and combined
heat and power technologies (CHP)
help to improve the electrical and
total efficiencies of modern power
plants from 35% to about 60%.

Stirling Engine –
Bringing Electricity to
Remote Locations
The alpha configuration locates the
piston and the displacer in separate
cylinders, and attaches the heater
and the cold sink to either cylinder.
Alpha engines have good reliability
and efficiency. It used MATLAB to
simulate data collection
