DESIGN AND CONSTRUCTION OF A PORTABLE SOLAR WATER HEATER
ABSTRACT
The technology of solar water heating is an emerging field in Nigeria. Due to the epileptic power supply in Nigeria, other energy sources are being sought. This project involves the design and fabrication of a portable solar water heater. The design of the solar water heater was done using relevant equations to size the major components of the system. The materials for the components were then selected with consideration to the design calculations, machinability, market availability and cost of the materials. The system was then constructed using the selected materials. The system consists of a buffer tank, an insulated storage tank of 36 litres capacity, a flat-plate collector with a single layer of glass on top, and a flow channel arranged in a serpentine manner. The thermosyphon principle was applied to the system and an average flow rate of 0.15 litres /min was recorded. The system was tested for six days, the first three days of testing were during the late raining season and the last three days within the dry season. From the first three days of testing during the late raining season, the highest outlet temperature recorded was 650C. For the last three days of testing during the dry season, the highest outlet temperature recorded was 79.3 0C. This difference clearly shows that the system performs better during the dry season when the irradiance levels are higher. The highest irradiance recorded was 940 W/m2 on the sixth day of testing. The highest efficiency recorded from the system was 68.19% on the fourth day of testing.

WIND ENERGY POTENTIAL ASSESSMENT IN SOUTHWEST REGION NIGERIA
Abstract:
The assessment of wind energy potential is crucial for diversifying energy sources and promoting sustainable development, particularly in regions with abundant wind resources. This study investigates the wind energy potential in the Southwest region of Nigeria, an area known for its varied climate and topographical features. Using wind data collected from multiple meteorological stations within the region over a 12-month period, this research evaluates key parameters such as wind speed, direction, and frequency of occurrence. The study employs mathematical models, including the Weibull distribution, to analyze wind speed variations and estimate the energy potential across different locations within the Southwest region. The results indicate that the Southwest region of Nigeria has significant wind energy potential, with certain areas showing promising wind speeds that can support the installation of wind turbines for electricity generation. The findings suggest that harnessing wind energy could play a vital role in enhancing the energy mix in Nigeria, reducing dependence on fossil fuels, and mitigating the environmental impact of energy production. However, challenges such as high initial capital costs, infrastructural limitations, and land availability need to be addressed for effective implementation. This study provides a foundational framework for policymakers, energy developers, and researchers to further explore the integration of wind energy solutions in Southwest Nigeria.

DESIGN AND IMPLEMENTATION OF A MOBILE PHONE DETECTOR
ABSTRACT
This work involves the design and development of a mobile phone detector which is capable of detecting incoming and outgoing signals from mobile phones. The presence of an activated mobile phone can be detected by this handy, pocket-size mobile signal detector from a distance of one and a half meters, which could be used in preventing the use of mobile phones in examination halls, confidential rooms etc. It is also suitable for detecting the use of mobile phone for spying and unauthorized video transmission. The circuit can detect the incoming and outing calls, text messages, and video transmission even if the mobile is kept in the silent mode. The moment the gadget detects Radio Frequency (RF) transmission signal from an activated mobile phone, it starts sounding a beep alarm and the Light Emitting Diode (LED) blinks. The alarm continues until the signal transmission ceases. The circuit is assembled on a general purpose PCB as compact as possible and enclosed in a small box.
CHAPTER ONE
1.1 Background of the study
In recent years, there has been increasing focus on issues relating to the use of mobile phones in restricted, prohibited, and unauthorized areas. The reason for this increased interest is largely due to disturbance, as well as wrong and inappropriate usage of mobile phones by the owners and users alike. Other areas like churches, mosques, offices, and prisons, just to mention a few, are not left out. There is need for the detection of mobile phone signals in areas like these.
Efforts have been put in place in tackling this issue but they all have their own shortcomings, one of which is the mobile phone jammer. A mobile phone jammer is an instrument used to prevent cellular phones from receiving signals from base stations. When used, the jammer effectively disables cellular phones. These devices can be used in practically any location, but are found primarily in places where a phone call would be particularly disruptive because silence is expected. The shortcoming of such a technology is the inability to make calls especially in cases of emergencies. However, this mobile signal detector has the feature of receiving and making calls during emergencies, except that the alarm and the LED will keep beeping and blinking respectively. Mobile phones uses RF with a wavelength of 30cm at 872 to 2170 MHz that is, the signal is high frequency with huge energy. When the mobile phone is active, it transmits the signal in the form of sine wave which passes through the space. The encoded audio/video signal contains electromagnetic radiation which is picked up by the receiver in the base station.
1.2 Statement of the problem
The existing technology currently available in the open market utilizes mostly discrete components, and a design approach using a down converter in conjunction with a band pass filter. These technologies are not adequate because they are inaccurate and expensive.
1.3 Design procedure
An ordinary RF detector using tuned LC circuits is not suitable for detecting signals in the GHz frequency band used in mobile phones due to the high frequency at which it transmit and huge energy that it gives out.
Figure 1:
Block Diagram. The construction of this pocket size mobile phone signal detector is so simple and not expensive. For the construction to be understood and appreciated a more detailed description of the design is required using the block diagram. The design consists of four stages as shown in the block diagram. 1. The sensor stage 2. The power stage 3. Operational Amplifier (Op-Amp) stage 4. Response stage From the above block diagram, once the RF antenna receives wireless signal after the circuit has been powered by a 9 Volts dc battery, the operational Amplifier LM358AN amplifies the received signal which is turn triggers the buzzer and makes the LED to flicker when signal is detected.
1.4 Purpose of the study
To construct a mobile phone detector capable of effectively detecting signals from mobile phones
1.5 Limitations of the study
There was limited time and finance in the course of the study
1.6 Definition of terms
Mobile phone:
A mobile phone (also known as a cellular phone, cell phone, hand phone, or simply a phone) is a phone that can make and receive telephone calls over a radio link while moving around a wide geographic area. It does so by connecting to a cellular network provided by a mobile phone operator, allowing access to the public telephone network

DESIGN AND CONSTRUCTION OF A D.C TO A.C INVERTER SYSTEM
ABSTRACT
Power inverter is a device that converts DC power (also known as direct current), to standard AC power (alternating current). Inverters are used to operate electrical equipment from the power produced by a car or boat battery or renewable energy sources, like solar panels or wind turbines. DC power is what batteries store, while AC power is what most electrical appliances need to run so an inverter is necessary to convert the power into a usable form.
It is designed to meet up with the power demand in the offices and in homes in the absence of power supply from the national supply authority, NEPA. In order words the device / item serves as a substitute for NEPA which almost monopolises the power supply to people.
The level of the needed input voltage depends entirely on the design and purpose of the inverter. In many smaller consumer and commercial inverters a 12V DC input is popular because of the wide availability of powerful rechargeable 12V lead acid batteries which can be used as the DC power source
It is designed in such a way that it will take up 12v DC from battery and inverts it to an output of 220v, 50H2 AC. It makes no noise during operation and no hazardous carbon monoxide is generated in the surrounding. And this inverter delivers a power of 1KVA to a load, and for this reason it emits high current and requires thick wiring.

1.0 INTRODUCTION
A power inverter is a device that converts DC power (also known as direct current), to standard AC power (alternating current). Inverters are used to operate electrical equipment from the power produced by a car or boat battery or renewable energy sources, like solar panels or wind turbines. DC power is what batteries store, while AC power is what most electrical appliances need to run so an inverter is necessary to convert the power into a usable form. For example, when a cell phone is plugged into a car cigarette lighter to recharge, it supplies DC power; this must be converted to the required AC power by a power inverter to charge the phone.
In modified sine wave, The waveform in commercially available modified-sine-wave inverters is a square wave with a pause before the polarity transition, which only needs to cycle through a three-position switch that outputs forward, off, and reverse output at the pre-determined frequency. The peak voltage to RMS voltage does not maintain the same relationship as for a sine wave. The DC bus voltage may be actively regulated or the “on” and “off” times can be modified to maintain the same RMS value output up to the DC bus voltage to compensate for DC bus voltage variation.
The ratio of on to off time can be adjusted to vary the RMS voltage while maintaining a constant frequency with a technique called PWM. Harmonic spectrum in the output depends on the width of the pulses and the modulation frequency. When operating induction motors, voltage harmonics is not of great concern, however harmonic distortion in the current waveform introduces additional heating, and can produce pulsating torques.
Most AC motors will run on MSW inverters with an efficiency reduction of about 20% due to the harmonic content….READ MORE
1.1 OBJECTIVE OF THE STUDY
This inverter is capable of operating a wide variety of loads; electronic and household items including but not limited to TV, VCR, and satellite receiver, computers, and printers.
The objective of this project is to design and construct a modified sine wave inverter which is rated 1KW which can be powered from the source of 12V battery…READ MORE
1.2 LIMITATION OF THE PROJECT
This device is a modified sine wave inverter, which is designed to be powered with 12v battery. It will work effectively and produce direct current only when the battery is charged.
It is a 2.4 kva inverter which means that load equal or above the power rating should for no reason loaded to this device in order to avoid overload which can result system breakdown. Initially you need to shell out a lot of money for buying an inverter.
1.3 APPLICATION OF THE PROJECT
This study exposes me the applications and uses of a modified sine wave inverter which are as follows:
DC power source utilization
Inverter designed to provide 240 VAC from the 12 VDC source provided in an automobile.
An inverter converts the DC electricity from sources such as batteries, solar panels, or fuel cells to AC electricity. The electricity can be at any required voltage; in particular it can operate AC equipment designed for mains operation, or rectified to produce DC at any desired voltage.
Uninterruptible power supplies
An uninterruptible power supply (UPS) uses batteries and an inverter to supply AC power when main power is not available. When main power is restored, a rectifier supplies DC power to recharge the batteries.
Induction heating
Modified Sine wave Inverters convert low frequency main AC power to higher frequency for use in induction heating. To do this, AC power is first rectified to provide DC power. The inverter then changes the DC power to high frequency AC power.
HVDC power transmission
With HVDC power transmission, AC power is rectified and high voltage DC power is transmitted to another location. At the receiving location, an inverter in a static inverter plant converts the power back to AC. The inverter must be synchronized with grid frequency and phase and minimize harmonic generation.
Variable-frequency drives
A variable-frequency drive controls the operating speed of an AC motor by controlling the frequency and voltage of the power supplied to the motor. An inverter provides the controlled power. In most cases, the variable-frequency drive includes a rectifier so that DC power for the inverter can be provided from main AC power. Since an inverter is the key component, variable-frequency drives are sometimes called inverter drives or just inverters.
VFDs that operate directly from an AC source without first converting it to DC are called cyclo-converters. They are now commonly used on large ships to drive the propulsion motors.
Electric vehicle drives
Adjustable speed motor control inverters are currently used to power the traction motors in some electric and diesel-electric rail vehicles as well as some battery electric vehicles and hybrid electric highway vehicles such as the Toyota Prius, BYD e6 and Fisker Karma. Various improvements in inverter technology are being developed specifically for electric vehicle applications.In vehicles with regenerative braking, the inverter also takes power from the motor (now acting as a generator) and stores it in the batteries.
Air conditioning
An inverter air conditioner uses a variable-frequency drive to control the speed of the motor and thus the compressor.
Electroshock weapons
Electroshock weapons and tasters have a DC/AC inverter to generate several tens of thousands of V AC out of a small 9 V DC battery. First the 9VDC is converted to 400–2000V AC with a compact high frequency transformer, which is then rectified and temporarily stored in a high voltage capacitor until a pre-set threshold voltage is reached. When the threshold (set by way of an air gap or TRIAC) is reached, the capacitor dumps its entire load into a pulse transformer which then steps it up to its final output voltage of 20–60 kV. A variant of the principle is also used in electronic flash and bug zappers, though they rely on a capacitor-based voltage multiplier to achieve their high voltage.
1.4 INVERTER RATINGS
The ratings that you should look at when buying an inverter (depending on the type) are:
Continuous Rating: This is the amount of power you could expect to use continuously without the inverter overheating and shutting down.
Half Hour Rating: This is handy as the continuous rating may be too low to run a high energy consumption power tool or appliance, however if the appliance was only to be used occasionally then the half hour rating may well suffice.
Surge Rating: A high surge is required to start some appliances and once running they may need considerably less power to keep functioning. The inverter must be able to hold its surge rating for at least 5 seconds. TVs and refrigerators are examples of items that require only relatively low power once running, but require a high surge to start.
IP rating – defines the ability of the inverter seals to prevent water and dust ingress. Although some inverter manufacturers claim high IP ratings suitable for outdoor installation, the quality and location of the seals and ventilation will greatly affect the ability of the inverter to outlast the many years solar installations are expected to work.
Peak efficiency – represents the highest efficiency that the inverter can achieve.
1.5 WHY CHOOSE A MODIFIED SINE WAVE INVERTER?
For running typical resistive loads like lights and appliances, a modified sine wave inverter is a reliable, cost-effective choice. Though modified sine wave inverters do not produce a perfect replica of AC true sine wave power, they do provide an affordable option that for many mobile power applications is perfectly adequate. Some devices, however, may not recognize the modified sine wave and may run poorly or not at all. The solution to these issues is to purchase a Go Power! pure sine wave inverter. For most applications though, a Go Power modified sine wave inverter is a reliable and cost-effective mobile-power solution. See our Inverter Comparison for details.
Some of our most popular modified sine wave inverters are from our Heavy-Duty line up. These are excellent solutions for fleet, utility trucks and vans looking for a powerful and economical alternative to a pure sine wave product.
1.6 TYPES OF INVERTER
There are different types of inverters for home and industries available which can suit your various electricity needs. Following are the two basic types of inverters.
Modified Sine Wave Inverters
This type of home inverter obtains power from a battery of 12 volts and must be recharged using a generator or a solar panel. Appliances like microwave ovens, light bulbs, etc. Can be run using these types of inverter.
They can be rightly held as the best inverters for homes as they are efficient enough to provide power to the normal home requirement.
They are the home inverters that are most affordable too.
You can run the daily used home appliances using the modified sine wave home inverters.
The electric appliances that involve motor speed controls or timers are not to be run using these types of home inverters.
The wave form of a modified sine wave inverter is as below:
modified sine-wave
2. True sine wave inverters
This is one of the better types of inverters as they provide better power as compared to the modified sine wave inverters for homes. These types of home inverter are also run using a battery of a larger capacity.
Technically speaking, the sine waves they produce are purer, thus the efficiency.
They are best inverters employed for the power sensitive appliances like refrigerators, televisions, air conditioners, washing machines, etc.
These types of inverters are extremely reliable. The only drawback is that they are a bit expensive and cannot be afforded by the common man.
There are various models available based on the electricity requirement of the house.
The wave form of a sine wave inverter is as below:
pure sine-wave
3. Square wave inverter
This is the simplest form of output wave available in the cheapest form of inverters. They can run simple appliances without problem but much else. Square wave voltage can be easily generated using a simple oscillator. With the help of a transformer, the generated square wave voltage can be transformed into a value of 240VAC or higher.
The wave form of a square wave inverter is a below:

1.8 IMPORTANT CONSIDERATION FOR INVERTERS
Before going into construction of an inverter, students must know the following:
OUTPUT FREQUENCY
The AC output frequency of a power inverter device is usually the same as standard power line frequency, 50 or 60 hertz
If the output of the device or circuit is to be further conditioned (for example stepped up) then the frequency may be much higher for good transformer efficiency.
OUTPUT VOLTAGE
The AC output voltage of a power inverter is often regulated to be the same as the grid line voltage, typically 240 VAC, even when there are changes in the load that the inverter is driving. This allows the inverter to power numerous devices designed for standard line power.
Some inverters also allow selectable or continuously variable output voltages.
OUTPUT POWER
A power inverter will often have an overall power rating expressed in watts or kilowatts. This describes the power that will be available to the device the inverter is driving and, indirectly, the power that will be needed from the DC source. Smaller popular consumer and commercial devices designed to mimic line power typically range from 150 to 3000 watts.
Not all inverter applications are solely or primarily concerned with power delivery; in some cases the frequency and or waveform properties are used by the follow-on circuit or device.
BATTERIES
The runtime of an inverter is dependent on the battery power and the amount of power being drawn from the inverter at a given time. As the amount of equipment using the inverter increases, the runtime will decrease. In order to prolong the runtime of an inverter, additional batteries can be added to the inverter.
When attempting to add more batteries to an inverter, there are two basic options for installation: Series Configuration and Parallel Configuration.
Series configuration
If the goal is to increase the overall voltage of the inverter, one can daisy chain batteries in a Series Configuration. In a Series Configuration, if a single battery dies, the other batteries will not be able to power the load.
Parallel configuration
If the goal is to increase capacity and prolong the runtime of the inverter, batteries can be connected in parallel. This increases the overall Ampere-hour(Ah) rating of the battery set.
If a single battery is discharged though, the other batteries will then discharge through it. This can lead to rapid discharge of the entire pack, or even an over-current and possible fire. To avoid this, large paralleled batteries may be connected via diodes or intelligent monitoring with automatic switching to isolate an under-voltage battery from the others

DESIGN AND CONSTRUCTION OF A BATTERY CHARGER
ABSTRACT
This project presents the design and construction of a battery charger. A battery charger is an electrical/electronic device used to put energy into a secondary cell or rechargeable battery by forcing an electric current through it. The system consists of a step down transformer, an AC to DC converter and a DC voltage regulator. The circuits are designed using copper wire, rectifier diodes, electrolytic capacitors, resistors with other passive and active component of electronics. A battery charger is an indispensible device for battery users because battery is an essential element that powers any electronic products like UPS inverters system, photographic equipments, hand-held lamps (flashlight or torch), computer-memory standby, toys, novelties and automobiles, etc. These products will become useless if there is no charger to refill their battery when it runs down. In this project, a sophisticated class of battery charger is designed not just to refill rechargeable batteries but to conserve the battery life because wronghandling and charging of a battery can permanently damage the battery even if is brand new. With this project, people can recharge both alkaline, NiCad and lead acid batteries by themselves and then save money on battery purchases.
CHAPTER ONE
INTRODUCTION
1.1 Background of Study
Few modern electrical appliances receive their power directly from the Utilitygrid like National Electricity Power Authority (NEPA) or Power Holding Company of Nigeria (PHCN), while a growing number of everyday electronic and electrical devices require electrical power from batteries in order to achieve greater mobility and convenience. Rechargeable batteries store electricity from the utility grid for later use and can be conveniently recharged when their energy has been drained. According to Woodbank Communications Ltd in their 2005 battery chargers and charging methods review inhttp://www.mpoweruk.com, battery charging involves three key functions: getting the charger into the battery (charging), optimizing the charging rate (stabilizing) and knowing when to stop (terminating). Appliances that use rechargeable batteries include everythingfrom low-power mobile cell phones to high-power industrial fork lifts. The sales volume of suchproducts has increased dramatically in the past decade. Hundreds of millions of theseproducts are sold annually to businesses and consumers, with close to a billion in U.S and Nigeria.
While designers of battery chargers often maximize the energy efficiency of their devices to ensure long operation times between charging. They often ignore how much energy is consumed in the process of converting ac electricity from the utility grid into dc electricity stored in the battery. In this project design, significant energy savings are possible by reducing the conversion losses associated with charging batteries in battery-powered products. We could save a lot of electric power using new electronic technology in our charging system and then highlight several design strategies for improving the efficiency of other chargers. We introduced a smart or intelligent battery charger that does not only recharge batteries but conserves AC electrical energy and as well save the battery life. Most battery chargers require human attention say Chu, Kim-Chiu the writer ‘development of intelligent battery charge’ (1989), from the University of Hong Kong, but in this project, an automatic battery monitor is used to reduce human attention to about 85 per cent to eliminate overcharging of batteries.
1.2 What is A Battery Charger?
A battery charger is a system that draws energy from the grid, store it in a battery, and release it to power a device is called a battery charger system.
A system designer in ADACC(Engr. A.A Ndubuisi) in his 1999article describes a battery charger is an electrical and electronic device that is used to put energy into a secondary cell or rechargeablebattery by forcing an electric current through it.The charging protocol of a battery charger depends on the size and type of the battery being charged. Some battery types have high tolerance for overcharging and can be recharged by connection to a constant voltage source or a constant current source; simple chargers of this type require manual disconnection at the end of the charge cycle, or may have a timer to cut off charging current at a fixed time. Other battery types cannot withstand long high-rate over-charging; the charger may have temperature or voltage sensing circuits and a microprocessor controller to adjust the charging current, and cut off at the end of charge. A trickle charger provides a relatively small amount of current, only enough to counteract self-discharge of a battery that is idle for a long time. Slow battery chargers may take several hours to complete a charge; high-rate chargers may restore most capacity within minutes or less than an hour, but generally require monitoring of the battery to protect it from overcharge.
Christine T. Bryant, (1990) say not all chargers can recharge alkaline batteries. It makes sense to use alkaline batteries while powering electronic systems even though they are difficult to recharge but they do not have a self-discharge. This is because alkaline batteries have long shelf lives and do not suffer the ‘memory effects’ of Nickel-cadmium batteries. The term ‘memory effects’ refers to the batteries becoming weaker with continued use, particularly when the batteries have seen light use and do not respond well to further charging. The problem stems from low battery currents which flow from only a small part of the active anode area of the battery. If higher current had been drawn or if the battery had been completely discharged, the whole active area of the anode would have been involved. The unused area essentially ‘films over’ and acts as a barrier to current flow. Further charging does not restore the active area. This is a chemical change causing the electrodes to degenerate in Nickel-metal hydride and Nickel-cadmium batteries. It is reversible by charging and discharging several times. Batteries that are not recharged before use will not supply the full amount of stored energy. None of the above happens with common alkaline batteries. The rate of self discharge in Nickel-cadmium is about 2% per week, in Nickel-metal hydride it is about 3% per week. At temperatures higher than room temperature, these rates increase. Using the wrong charger on alkaline batteries can be downright dangerous. If you read the warning labels printed on ordinary batteries, you will observe that a NiCad charger should never be used on alkaline batteries. Such a charger would supply currents in excess of safe values, would not turn off automatically when battery voltage exceeds safe limits, and would continue unchecked until the battery was damaged.In order to achieve ten times extension of the normal life of an everyday alkaline battery, you will have to recharge it frequently, many more times than ten. With this project it is possible to recharge both alkaline and NiCad batteries because the system has anautomatic battery monitor which monitor and adjust the charging rate of batteries. Charge rate is often denoted as C or C-rate and signifies a charge or discharge rate equal to the capacity of a battery in one hour. For a 1.6Ah battery, C = 1.6A. A charge rate of C/2 = 0.8A would need two hours, and a charge rate of 2C = 3.2A would need 30 minutes to fully charge the battery from an empty state, if supported by the battery. This also assumes that the battery is 100% efficient at absorbing the charge. A battery charger may be specified in terms of the battery capacity or C rate; a charger rated C/10 would return the battery capacity in 10 hours, a charger rated at 4C would charge the battery in 15 minutes. Very rapid charging rates, 1 hour or less, generally require the charger to carefully monitor battery parameters such as terminal voltage and temperature to prevent overcharging and damage to the cells.
1.3 Aims and Objective
The major aim and objective of this project is to design and construct a battery charger that can be use to charge any kind of 12v rechargeable batteries including alkaline, NiCad or lead acid batteries. With the lack of centralized power grids, car batteries have taken the place of oneof the main energy sources available in developing countries. With this in mind, ourobjective will be to design a cheap, versatile and efficient lead acid car battery charger which will interest and appeal to the “cost-minded” customer.One of our main incentives in developing this project is for a low-cost charger (affordable) to integrate or combine with otherdevice. After carrying out our project research on the targeted users, they have been able todevise a list of particular features that would be essential in the project, like designing battery charger to be universal. Using a standard AC power, ability to charge a typical 12 Volt lead-acid (automotive) battery.We used these requirements as guidelines to implementing our product as well as include additional features that we thought are important to the functionality.
1.4 Scope
The scope of this project is to have a direct current battery charger of 12 Volts and 10 Amp maximum which can be suitable for car batteries and electric vehicles. Electric vehicles need high-rate chargers for public access.
1.5 Significant of the Project
The significant of this project is not just to recharge batteries but it works as a D. C power adapter for experimentation. It may, however, require an externalcapacitor to be connected across its output terminals in order to “smooth” the voltage sufficiently, which may be thought of as a DC voltage plus a “ripple” voltage added to it. The project is also significant because children will be attracted to charging their own batteries in their toys and possessions. Managing their own batteries is fun, and they know it helps the environment by not having to throw batteries away when they can recycle them.
1.6 Limitations
The project is limited to 12V batteries. It is not advisable to use it on rechargeable batteries above 12V. Also there is no internal resistanceconnected in the battery charger to limit the short circuit current.
1.7 Constraints
The biggest setback experienced during the course of this project is financial difficulties in funding the design of the project. Secondly, sourcing of materials and components used was not easy. Finding the rectifier diode and DC regulator for this charger was not an easy task. We had to destroy many electronic devices for solution. Some of the components we used for this project were very difficult to find. Furthermore, we received a severe electric shock while trying to plug in the workbench power supply to test our design and that made us to almost give up.

DESIGN AND CONSTRUCTION OF A SOLAR WATER HEATER
ABSTRACT
The technology of solar water heating is an emerging field in Nigeria. Due to the epileptic power supply in Nigeria, other energy sources are being sought. This project involves the design and fabrication of a portable solar water heater. The design of the solar water heater was done using relevant equations to size the major components of the system. The materials for the components were then selected with consideration to the design calculations, machinability, market availability and cost of the materials. The system was then constructed using the selected materials. The system consists of a buffer tank, an insulated storage tank of 36 litres capacity, a flat-plate collector with a single layer of glass on top, and a flow channel arranged in a serpentine manner. The thermosyphon principle was applied to the system and an average flow rate of 0.15 litres /min was recorded. The system was tested for six days, the first three days of testing were during the late raining season and the last three days within the dry season. From the first three days of testing during the late raining season, the highest outlet temperature recorded was 650C. For the last three days of testing during the dry season, the highest outlet temperature recorded was 79.3 0C. This difference clearly shows that the system performs better during the dry season when the irradiance levels are higher. The highest irradiance recorded was 940 W/m2 on the sixth day of testing. The highest efficiency recorded from the system was 68.19% on the fourth day of testing.
CHAPTER ONE
INTRODUCTION
1.1 Background
The world relies heavily on fossil fuels for most of its energy demands, and this has caused a lot of harm to the Earth. The increase of green-house gas levels in the atmosphere is largely due to the combustion of fossil fuels as a source of energy. This has caused global warming which has led to climate change, floods, forest fires, rising sea levels and the melting of glaciers. These are just some consequences of the over-reliance on fossil fuels for our energy demands. Solar energy provides an alternative and environmentally friendly energy source to the fossil fuels used for our energy needs. Over the last few decades, solar energy systems have gained more recognition because they can provide energy at a low long-term cost and minimal environmental damage. Researchers have developed several techniques for harnessing solar energy, these techniques include applications for space heating, water heating, electricity generation and many others.
Solar energy is generated by the fusion reaction of hydrogen atoms in the sun. This fusion reaction results in the release of high-energy particles called gamma rays. Gamma rays are transmitted as electromagnetic radiation to the Earth, which is at about 150 million kilometres from the sun. Electromagnetic radiation comes in three forms: infrared rays, visible light, and ultraviolet rays. Solar energy reaching the Earth’s surface can be harnessed directly by using photovoltaics (solar cells) and solar concentrators. Photovoltaics are used for electricity generation, while solar concentrators are used as a source of thermal energy. The utilization of solar energy collectors (concentrators) to transform radiation into heat energy is the basis of the solar water heating technology. A simple solar water heater consists of a collector, a tank, and the flow channel through which the working fluid is transported.
Records show the solar water heater (SWH) was first invented in the Roman empire around 200 B.C.E (Gong & Sumathy, 2016). The Romans had a simple system, they used the solar heating concept to heat their public baths to enable a reduction in using coal and the labour required. These systems were not self-sufficient, but every innovative idea starts somewhere, and the solar water heating concept began here. After the Roman empire collapsed, humans forgot the concept of using the sun to heat water for over a millennium. It was in the late 18th century (1767) that a Swiss natural scientist, De Saussure, re-introduced the concept of using solar energy for water heating (Gong & Sumathy, 2016). He built an insulated box with two glass panes covering the surface, the bottom of the box was painted black to increase solar radiation absorption. This is the prototype for all solar water heaters. De Saussure found that whenever the insulated box was exposed to solar radiation, the insides reached temperatures greater than water’s boiling point. He had shown the green-house effect for the first time by doing this (Perlin, 2008). De Saussure hoped researchers would find his innovative device useful, but it took over a century for this to happen.
In 1891, Clarence Kemp, an American manufacturer, patented the world’s first commercial SWH called Climax (Gong & Sumathy, 2016). It was a simple system in which he put the black coated metal tank in an insulated box which had comparable designs to that of De Saussure’s. This metal tank served as both the solar energy collector and storage. The major issue with
Kemp’s invention was that the water was stored and heated in the same tank. Hence, when exposed at night and in poor weather, the water sometimes cooled down to an undesired temperature. William J. Bailey solved this drawback in 1909 by developing a system which had the collector and the tank separate from each other. The solar collector he built comprised fluid tubes connected to a black-coated metallic plate in a box with a transparent surface. The storage tank for the system was placed above the collector. It was the first system in history that transported the working fluid using the thermosyphon principle. This principle made it possible for water to circulate without the use of a mechanical pump. William Bailey’s company was called the Day and Night SWH Company, emphasizing the advantage his solar water heating system had over that of Clarence Kemp’s. By the 1920s, the discovery of natural gas and oil in southern California led to the emergence of gas water heaters. This crippled the solar water heating industry. Reductions in electricity cost and the copper scarcity during the second world war replaced whatever was left of the solar industry.
In the 1970s, about half a century later, the SWH got global attention again, revitalized by the OPEC embargo which caused a major oil crisis and a hike in oil prices. Ever since, the solar water heating industry has expanded all over the world. Growing concerns about the planet’s increasing carbon emissions, global warming and climate change have flared up interest in the solar water heating industry. As of 2018, the SWH market was valued at over a billion dollars, the yearly installation is expected to surpass three million units by 2025 (Gupta, 2019).
1.2 Problem Statement
Considering the epileptic nature of electric power supply in Nigeria, the reliance on solar applications for water heating will lead to better reliability of service for hot water needs and will have minimal negative impact on the environment. This would reduce the reliance on electric heaters, which have higher operational costs and depend on fossil fuels as a primary energy source.
1.3 Motivation for the Study
A lot of research has gone into the solar energy field over the past few decades. This is mostly because of the increased world-wide acknowledgement of the environmental effects that the use of fossil fuel as an energy source comes with. This current study would result in the design and construction of a portable solar water heating system which would provide hot water. The use of locally sourced materials would reduce the financial resources required compared to the importation of these materials. With Nigeria going through a recession and a pandemic which has further impacted the nation’s economy, the availability of locally made solar water heating systems would help boost the local economy and curb the rate of importation.
1.4 Scope of the Study
This study is limited to the design and construction of a portable flat-plate solar water heating system operating on the thermosyphon principle. The application of the thermosyphon principle eliminates the need for an electric pump, thereby reducing the cost of the SWH. The material resources required for the construction of a flat-plate collector operating on the thermosyphon principle are readily available in Nigeria.
1.5 Aim and Objectives
The aim of this project is to design and construct a portable solar water heater. The objectives are:
1. To design a portable solar water heater .
2. To construct the portable solar water heater.
3. To carry out the performance evaluation of the constructed solar water heater.
4. To obtain a baseline cost of a locally built solar water heater.

CONSTRUCTION OF AN AC TRANSFORMER 220_110V
ABSTRACT
A transformer is an electrical device that transfers energy between two or more circuits through electromagnetic induction. A varying current in the transformer’s primary winding creates a varying magnetic flux in the core and a varying magnetic field impinging on the secondary winding.
Step down transformer: is one whose secondary voltage is less than its primary voltage. It is designed to reduce the voltage from the primary winding to the secondary winding. This kind of transformer “steps down” the voltage applied to it.
As a step-down unit, the transformer converts high-voltage, low-current power into low-voltage, high-current power. The larger-gauge wire used in the secondary winding is necessary due to the increase in current. The primary winding, which doesn’t have to conduct as much current, may be made of smaller-gauge wire.
The aim of this work is to design and construct a step-down transformer with a primary voltage of 220V and a secondary voltage of 110V.
CHAPTER ONE
INTRODUCTION
1.1 BACKGROUND OF THE STUDY
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. Electromagnetic induction produces an electromotive force across a conductor which is exposed to time varying magnetic fields. Commonly, transformers are used to increase or decrease the voltages of alternating current in electric power applications.
A varying current in the transformer’s primary winding creates a varying magnetic flux in the transformer core and a varying magnetic field impinging on the transformer’s secondary winding. This varying magnetic field at the secondary winding induces a varying electromotive force (EMF) or voltage in the secondary winding due to electromagnetic induction. Making use of Faraday’s Law (discovered in 1831) in conjunction with high magnetic permeability core properties, transformers can thus be designed to efficiently change AC voltages from one voltage level to another within power networks.
For the course of this work, which is on step down transformer which is used when one travel from a 110V region with your 110V devices to a 220V region, you’ll need a Step Up Converter. And likewise, if you travel from a 220V country to say, America, a 110V country, you will need to convert down using a Step Down Converter.
A step down transformer: is one whose secondary voltage is less than its primary voltage. It is designed to reduce the voltage from the primary winding to the secondary winding. This kind of transformer “steps down” the voltage applied to it.
As a step-down unit, the transformer converts high-voltage, low-current power into low-voltage, high-current power. The larger-gauge wire used in the secondary winding is necessary due to the increase in current.
1.2 OBJECTIVE OF THE PROJECT
Step down transformer is designed to reduce the voltage from the primary winding to the secondary winding. This kind of transformer “steps down” the voltage applied to it. The aim of this work is to construct a transformer with a primary voltage of 220V and a secondary voltage of 110V. At the end of this work:
a transformer with primary voltage of 220V and a secondary voltage of 110V would be constructed.
Principle of operation of a transformer would be learned
Different types of transformer will be discussed
Different types of Cooling systems of a transformer will be discussed
1.3 SIGNIFICANCE OF THE PROJECT
A step down transformer is needed to decrease the incoming 220 Volt electricity found in most parts of the world to 110 Volts USA power. It can be safely used continuously for 110 volt American products in countries with 220 volt power supply.
1.4 APPLICATION OF THE PROJECT
Step down Transformers are also used extensively in electronic products to decrease (or step-down) the supply voltage to a level suitable for the low voltage circuits they contain. The transformer also electrically isolates the end user from contact with the supply voltage.
1.5 SCOPE OF THE PROJECT
This is a step-down transformer, as evidenced by the high turn count of the primary winding and the low turn count of the secondary. As a step-down unit, this transformer converts high-voltage, low-current power into low-voltage, high-current power. The larger-gauge wire used in the secondary winding is necessary due to the increase in current. The primary winding, which doesn’t have to conduct as much current, may be made of smaller-gauge wire.
In this work, it is possible to operate either of these transformer types backwards (powering the secondary winding with an AC source and letting the primary winding power a load) to perform the opposite function: a step-up can function as a step-down and visa-versa. However, as we saw in this work, efficient operation of a transformer requires that the individual winding inductances be engineered for specific operating ranges of voltage and current, so if a transformer is to be used “backwards” like this it must be employed within the original design parameters of voltage and current for each winding, lest it prove to be inefficient (or lest it be damaged by excessive voltage or current).
Transformers are often constructed in such a way that it is not obvious which wires lead to the primary winding and which lead to the secondary. One convention used in the electric power industry to help alleviate confusion is the use of “H” designations for the higher-voltage
