INTRODUCTION
Today Nigeria faces a destabilizing dependency on irreplaceable fossil fuels which
are also rapidly dwindling. As shortages of oil and natural gas occur with more
frequency, i.e “New Energy Crisis and removal of the oil subsidy” is now allover the
nations.
The global consumption of energy is growing and there is need for new renewable
energy sources. Among the following energy sources that could be free from carbon
dioxide are wind, wave and tidal of photovoltaic and osmotic power.
Therefore, in order to find other ways of producing energy, a number of alternatives
have been considered. One of these alternatives is the generation of electricity from
a fuelless engine in an isolated power generation system with low maintenance cost.

A fuel-less engine is an engine that produces electricity 24/7 without fuel (petrol,
diesel, oil, grease, gas, wind energy). Fuel-less engine can replace any of these
engines types. Fuel-less engine has very little impact on the environment, noiseless,
pollution free, self-dependent. It can be built to the capacity of the load you want it
to carry. The driving mechanism is the DC motor, which is driven by a battery (12V
or more). The battery drives the DC motor, which in turn spins the alternator to
produce electricity and at the same time, with the help of the rectifier, it recharges
back the battery. The fuelless engine usually runs very smooth and quiet and the
best part of the design is that it is free from air pollution, since there is no
emission of dangerous gas like Carbon monoxide (CO), carbon-dioxide (CO2)
The speed is adjustable or can be built to run a tone speed with engine which
does not run on any type of gasoline, oil or other combustible fuel.

INTRODUCTION
Once the rate of discharging the batteries is equal to the rate of charging the
batteries then the output voltage remains constant and the fuelless engine could
operate 365 days without any interruption. This is an ideal renewable energy
source. The source of energy comes from within the realm of physics but there is
an opposing challenge to the 1st law of thermodynamics which is generally
referred to as principle or law of conservation of energy. The technique to
generate electricity out of this fuelless engine has been tested and proved reliable
and steady.

STATEMENT OF PROBLEM
The Engineering challenge of generating energy from a fuel-less generator or engine
for useful work is, at the turn of this century, plagued by ignorance, prejudice and
disbelief. The power engineers’ community does not in general acknowledge the
emerging opportunities from fundamental discoveries of fuelless energy. Instead, there
are many expositions from prominent sources against it.

AIMS AND OBJECTIVES THE STUDY
 Aim
The aim of this study is to design and fabricate a 1KVA fuel-less generator that is
efficient and less energy consuming.
 Its specific objectives are:
1. To provide an alternative to high cost of fuel and for the normal generators which is
not environmental friendly.
2. To design a portable fuel-less generator that can be very affordable.
3. To determine the efficiency of the designed generator
4. To analyze the input and output characteristics of the designed generator.

SCOPE AND LIMITATION
Scope
The project covers the design and fabrication of a 1 KVA fuel-less generator. The
raw materials required for the fabrication will be sourced for locally.
Limitation
The limitation of this project is that the design and construction of this fuelless
generator is limited to a maximum output 1KVA of electric power. This means that
the generator can only be put to use in areas that do not demand more than 1KVA of
power.

LITERATURE REVIEW
AUTHOR TITLE FINDINGS LIMITATION
Azeez N. A1 et.al DESIGN AND
CONSTRUCTION OF A
FUEL LESS
GENERATOR
It can be deduced that the
machine (fuel-less power
generating set) had the peak
efficiency of 89.5% at a load of
180W and the lowest efficiency
of 68.7% at a load of 720W.It was
also revealed that there is a
decrease in the output of the
machine when there is a high
increase in the load. After proper
statistical analysis, the machine is
said to have an average efficiency
of 56.4%. The input voltage
which is usually supplied by the
battery ranges from 11.68V at
load of 900W to 12.67 at 0W.
The project setup cannot
operate over a long period of
time, because of the over
heating of the D.C (opposing
force) which ocour due to
applied of load. It is also not
self sustainable. Finally, the
whole system is subjected to
many losses such as losses due
to air friction and mechanical
losses from the mechanical
bearings, which in turn
reduces its efficiency

PERFORMANCE
EVALUATION
The fuelless generator has an
average efficiency of 56.43% at
load of 600W for continuous
operation.
The peak efficiency of the
constructed fuel-less power
generating set was 89.1% at load
of 100W.
The fuelless generator is
limited to a maximum output
1KVA of electric power. This
means that the generator can
only be put to use in areas that
do not demand more than
1KVA of power.

LITERATURE REVIEW
Empirical Review
The exert nature of electricity is not known but investigation indicate that it consist of small
negative charge called Electron, when this electron are standing still we have static electricity”
and when they are forced to traveled a movement of electron they are called “Dynamic
electricity.” Power generation and distribution has been an indispensable factor in the
progress of an economy, ranging from manufacturing, banking, media, health care, aviation,
etc. (Ulaby, 1999).
Gap in Literature
An exhaustive literature review has revealed that the project works on the fuel-less generator
has been efficacious; enough electrical power output has been obtained in every case, which
can decipher a solution to electric power instability in the country. However, the past work
have not laid much emphasis on the cost reduction factor in producing the fuel-less generator,
and the performance parameters to enhance the efficiency of the fuel-less generator, hence the
focus of this project work is to explore the fundamental performance parameters affecting the
performance of the fuel-less generators and a new approach for obtaining zenith efficiency
from the generator.

MATERIALS AND METHOD
The design constraints were all analysed by studying the literature survey carefully and choosing the best
possible design for the most efficient outcomes in order to enhance workability of the project.
Direct current generators DC (DC Motor) :
 Alternator:
 Battery: 12v 62
 Rectifier/Diode:
 The crankshaft:
 Cables:
 Frame and casing
 Switch:
 Capacitor:

Construction/Design Procedures
In the design of the fuel-less generating set, the following procedural steps are used
to achieve the aims and objectives of the construction work.
 Step 1: Fabricated crankshaft with a bore-hole that conveniently fit in to the DC
motor with thread-hole that bolt the motor to the crankshaft.
 Step 2: Fitted the fabricated crankshaft in to the DC motor
 Step 3: Inserted the DC motor with crankshaft into the crank casing of the alternator.
Step 4: Fit the armature of the alternator into the casing.
 Step 5: Dropping the stator core of the alternator into the armature

 Step 6: Inserted a long bolt through the bearing end of the stator and tighten firmly
to connect the motor and the alternator together.
 Step 7: Replaced the cover of the alternator and fasten both the cover and the
crankcase together.
 Step 8: Constructed a frame for the generator to provide support and rigidity
 Step 9: Connected the diode to green cables and capacitor to the yellow ones.
Step 10: Connected the terminals of the DC motor to equivalent terminals of the
battery
Step 11: Connected the red cables to the mains as output.

EXPECTED RESULT
The evaluation of the machine will be calculated using the formula below as stated
by Akintunde et al (2004);
Efficiency = output power x 100
𝑖𝑛𝑝𝑢𝑡𝑝𝑜𝑤𝑒𝑟
This evaluation is intended to establish the conversion efficiency between the fuel-
less D.C source (Battery) input and the AC output.
Load capacity expect from this research work ranges from 0 watt to1000 watts; that
is from 0% to 100% loading. The speed of the motor used was 9000rpmwhile that of
the alternator was 6000rpm. This simply means that there is direct coupling of the
motor and the alternator.

CONCLUSION
The need for new energy sources had led to a number of alternatives with their
attendant teething high cost problems. However, in the future, if the technology is
further developed and embraced the costs will reduce to compete reasonably with
those of generators. Fuelless engine is a renewable energy source with insignificant or
no CO2 emissions when sparking occur at the batteries terminals as a result of partial
contact when wiring. Mostly, the fuelless engine potentials can be utilized by merely
replacing all the generating sets electric or fuel powered motors, with dc motors and
adequate chargers.
