Revving the Electrical Engineer

---The Electrical Engineer Editorial Board

As we focus on the Filipino electrical practitioners’ skills and potentials traversing borders in the international market, the “Electrical Engineer” hopes to spread its reach, through a faster and readily available medium – the internet.

Started last year, the “Electrical Engineer” is now downloadable from the website. Technical information, the industry and the profession’s latest development, and the Institute’s news are made accessible just a click away.

Reaching our readers is not only a function of time but also of breadth. Hence, technical articles will mostly populate the content of the magazine, paving for more avenues of mutual learning and continuing education. Detailed IIEE Chapter activities will be posted on the website. Albeit reducing the cost of publication and mailing, the timeliness of delivering the information has not been compromised.

As we tread towards a fast, paperless and readily available medium of publication, the doors for contributions from members and non-members alike are open, as always have been.

1. Implementation of the Amended Constitution and By Laws

The Amended Constitution and By-Laws of the IIEE was already ratified during the 2011 National Mid-Year Convention and General Membership Meeting held last May 21, 2011 in Bacolod City.

While on its transitory period, the IIEE Board of Governors approved the appointment of Ad-Interim Governors for the newly created regions --- Metro Manila and Western Mindanao. The Ad Interim Regional Governors have the functions of identifying the territorial jurisdiction of the three (3) regions in Mindanao and the revision of the IIEE Manual of Operations, with the inclusion of the newly established regions.

2. Phase 1 of Construction of of the New Building

The phase 1 of Construction of the New Building Project is scheduled for completion this year. The single-floor annex of the existing IIEE Building will be converted into a four-storey building. This will provide the needed additional space to host the secretariat, document center, more library space, sleeping quarters for IIEE officers and members from the provinces, expanded laboratory, the Energy Efficiency Training Center and additional training/ conference rooms. The IIEE is continually pursuing a program to solicit donations from kind hearted individuals and corporations to fund the project, especially the Phase 2; 3. Improving Services to Members through the adoption of performance metrics of the Balanced Scorecard (BSC) and the empowerment and recognition of Chapters who have demonstrated excellent work of service, innovations and dedication for their members.

We believe in the saying that “What we cannot measure, cannot be improved”. The Balanced ScoreCard System, used by many corporations with good governance, is introduced to the IIEE to measure and continually improve its services.

BSC involves coming up with performance indicators which will allow the Institute to check and track its service performance and be able to adjust its systems, policies and procedures to meet the requirements of its members, officers, the community and the PRC. This system covers 4 perspectives – (1) financial, (2) members, (3) processes and (4) learning, growth and community. The BSC provides feedback to the very competent and dedicated incumbent members of the Board of Governors in its desire to continually improve the organization. This system is also an excellent guide for the IIEE secretariat for continual self improvement in their work of service.

A similar approach is used to empower and recognize chapters who have provided excellent and unselfish service, innovations and dedication to duty for their members and the community.

4. Improving IIEE Processes such as registrations, issuance of certificates, technical sessions and license renewals through effective use of technologies such as the Internet, E-IDs, accurate Membership Database, and trained in-house personnel;

Since we do not expect different results if we do the same things, we are moving forward using different and innovative ways. With the innovations in modern technology, the Institute aims to utilize a system that will fast-track the different processes of the Institute.

For this year, the IIEE will launch the IIEE E-ID Card which will fast tract Membership Data accuracy/update, convention and technical sessions registration, issuances of certificates of participation, membership renewals, certificate of good standing among others, for the benefit of the members. An accurate and user friendly database supports our program to increase membership involvement in the electoral process.

5. Expand Information Dissemination through the Effective use of the Internet and the IIEE Web Site and community works;

The IIEE aims to intensify its efforts to feature various activities conducted by our chapters in the IIEE website. The aim is for the sharing of knowledge through articles, technical questions and answers, positive experiences and activities of members and chapters with other IIEE members, chapters and the community.

Furthermore, the IIEE created an Ad Hoc Committee on Website Development. This is to come-up with strategies to further improve the IIEE website and its contents.

6. Promoting Safety, Energy Efficiency, Power Quality and other advocacies through joint efforts and cooperation with other organizations and groups such as the LGUs, the Board of Electrical Engineering, ICA, among others.

The Institute will continue to strengthen its partnership with different government, private and industry sectors. The new phase of programs in promoting awareness in electrical safety, energy efficiency and power quality will be launched this year. This includes Fun Run for electrical safety awareness and an international convention on Power Quality to be held here.

Also, the IIEE will intensify its efforts to enjoin the LGUs to hire registered electrical practitioners in their municipalities in order to ensure electrical safety in the residential and commercial establishments in their municipalities. For the same reasons, the IIEE will continue to cooperate with the BEE in seeing to it that commercial and industrial establishments are complying with the provisions of the New Electrical Engineering Law.

7. Enhancing the skills development program for IIEE Members and students through more extensive technical seminars and conferences.

With a commitment to provide career growth and continuing professional education, the IIEE will develop new strategies in formulating a series of both technical and management trainings for the members and officers and even extending such trainings to out-of-school youths, barangay electricians and students.

Furthermore, the IIEE is encouraging the chapters to train Barangay electricians to upgrade their careers to Registered Master Electricians. 8. Expanding the call for the electric industry to be prepared for the effects of climate change particularly typhoons and floods and to address carbon emissions;

The Institute has its initiative to serve the general public through its advocacy of a better disaster response. The aim is to mitigate the effects of disaster-inflicted calamities that claim thousands of lives and damages to properties. Also, the IIEE advocates the development of renewable energy as a means to address carbon emissions detrimental to the environment. IIEE is assisting the IFC and ICA for programs that promote energy efficiency.

The Mid Year Convention in Cagayan De Oro this May, 2012 highlights the effects of climate change and the ideal responses to these effects. CDO itself was a calamity area last December 2011 and thus sharing of the experiences and responses of the electrical practitioners in CDO and Iligan City to the disaster is part of the convention.

This year’s thrust is reflected in the theme, “Engineering A Safe and Better Nation Through Excellence in Electrical

Profession”. The IIEE will focus on developing strategies, plans and programs towards excellence in electrical profession and nation building. These programs are guided by the core values of integrity, innovation, empowerment, excellence, honor and duty (IIEE-HD). Thus, as the National President, I am presenting the 8 Point Agenda for 2012.

Thus, Asian countries focus their goals and strategies in achieving global c o m p e t i t i v e n e s s to cope with the requirements and demands of the modern world. Wikipedia defines c o m p e t i t i v e n e s s as “a comparative concept of the ability and performance of a firm, sub-sector or country to sell and supply goods and/or services in a given market.” While, the International Institute of Management Development defines Global competitiveness as “a field of economic knowledge which analyzes the facts and politics that shape the ability of a nation to create and maintain an environment that sustains more value creation for its enterprises and more prosperity for its people”.

In the article, ‘The Imperatives for Enhancing Global Competitiveness’ written by Mah Lok Abdullah, he cited that the following issues are vital in enhancing global competitiveness: (1) Macroeconomic policies; (2) Government Practices and Regulations; (3) The Cost of Doing Business; (4) Upgrading of Education and Skills; (5) Research and Development & Innovation; (6) Sustainable Environmental Management; (7) Conformity with International Standards; and (8) Total Factor Productivity.

Overseas Filipino Workers in Global Competition

According to the POEA 2010 Overseas Employment Statistics, about 280,000 composed of new hires and re-hires are being deployed in Asia alone. POEA 2010

data shows that 40% of the newly deployed OFW’s are categorized as “Professional, Technical and Related Workers” are composed of 3,486 are Engineering Technicians (Electrical and Electronics) and 1,290 full-fledged Engineers (Electrical and Electronics).

Human Resources as A Factor of Global Competitiveness

Enhancing the human resources and productivity is one of the issues that needs to be addressed for a developing country like the Philippines. Human resources are considered as an investment by companies that compete in the global market.

The government should focus on improving the quality of educational system prior to the working

stage of a person. The educational system should be in accordance with the requirements and needs of the modern industry in response to the changing economic situation.

According to the article, ‘The Crisis Public Education in the Philippines’ written by Ronald Meinardus, “The modern world in which we live is often termed a as"knowledge society"; education and information have become production factors potentially more valuable than labor and capital. Thus, in a globalized setting, investment in human capital has become a condition for international competitiveness.”

IIEE Towards Global Competitiveness of Filipino Electrical Practitioners

The Philippine government established different plans and program to improve the quality of the educational system in the country.

Filipino Electrical Practitioners in a Globally Competitive EnvironmentWith the fast-paced innovation in technology and advances in information and communication system, the competition in the global market continues to increase.

Cover Story

President Benigno Simeon C. Aquino’s administration prioritized basic to higher education, with a 17% allocation on the National Budget, an increase of 11.4% as compared to the 2010 education budget. (Department of Budget and Management and by the Presidential Communications Development and Strategic Planning Office November 2010).

This budget allocation is said to provide sufficient funds to the education sector, to deal with the recurring problems and concerns in education.

The Department of Education overhauls the educational system in the country through the K-12 Basic Education Program. The program includes Kindergarten, Grade 1 to 6 (Elementary Education), Grade 7 to 10 (Junior High School) and Grade 11 to 12 (Senior High School). The two years additional (Grade 11 to 12) will be an in-depth study in a field of specialization depending on the career path that a student aims to pursue.

Continuing Professional Education

While the government sector focuses their strategies in pre-employment stage of an individual, the Institute of Integrated Electrical Engineers of the Philippines, Inc. (IIEE) continues with its mission of “delivering high quality products and services in order to instill excellence in the Electrical Practitioner, and to enhance the technical profession to enable it to make positive contributions to National Development.

Under the RA 7920, known as the New Electrical Engineering Law, all licensed electrical practitioners should abide by the rules and regulations on the Continuing Professional Education (CPE).

The CPE has the following objectives:

1. To provide and ensure the continuous education of PEEs, REEs and RMEs with the latest trends in the Electrical Engineering profession brought about by the modernization and scientific and technological advancement. 2. To raise and maintain the PEEs, REEs and RMEs capability for delivering professional services; 3. To attain and maintain the highest standards and quality in the practice of Electrical Engineering; 4. To make Filipino PEEs, REEs and RMEs globally competitive; and 5. To promote the general welfare of the public.

The Institute conducts in-house training in the IIEE National Office for electrical practitioners, members and non-members alike.

A monthly regional conference is being held to provide professional development and to enhance the technical skills and in-depth technical knowledge of its members in the local Chapters.

The Institute has its Annual National Convention, held every November of each year that features different activities such as Plant Tour, Technical seminars, fora and academic research contests.

Establishment of Foreign Chapters

As of 2011, the Institute has eight (8) foreign Chapters composed of electrical practitioners abroad. These chapters formulate different activities, plans and programs that are inclined with the thrust of the IIEE National Office towards the professional development and career growth of its members abroad.

These Chapters include (1) Bahrain Chapter, (2) Brunei Chapter, (3) Central Region Chapter --- Saudi Arabia, (4) Eastern Region Chapter --- Saudi Arabia, (5) State of Qatar, (6) Southern Region Chapter---Saudi Arabia, (7) United Arab Emirates Chapter, (8) Western Region Chapter---Saudi Arabia.

Only last January, the IIEE Board of Governors approved the creation of Singapore Chapter. The first IIEE Chapter in Southeast Asia initiated by the 2011 Lady Governor of Eastern/Central Visayas Region, Engr. Lelanie T. Mirambel.

IIEE continuing to carry on equipping the young minds and promote continuing education in order to progress towards economic development.


Energy Contraption Design Using Playground Seesaw ForLighting Load Applications

22nd ASEMEP National Technical Symposium

ABSTRACTEnergy contraption is widely used to produce electricity by transforming different kinds of energy into electrical. One of the sources of energy contraption is from everyday human activities. The playground is used everyday by children and produces motion which can be converted toelectrical energy. This study is about conversion of motionby children playing seesaw and storing it to a battery for future use. Using pneumatic principle, the mechanical energy from the motion of the seesaw is converted using the pneumatic principles. With the utilization of the microcontroller, the energy collected will be stored in thebattery and will stop the charging once the battery is full.The energy that is stored in the battery will supply mainlylighting loads.

1. 0 INTRODUCTIONPeople are in search of renewable sources of energy nowadays. With increasing demand and decreasing resources, many seek new ways of converting different forms of energy to electrical energy. Contraption is a way in which a strange machine or apparatus is invented for aparticular purpose Energy contraption nowadays has many applications in small scale or large scale. With further studies, it may be used to create a major source of renewable energy.

By harnessing human power from the children playing inthe playground, energy contraption could be further applied specifically in seesaw, merry-go-round, and swing. The mechanical energy produced by children’s play can useful and harnessed resulting to significant energy storage.

According to Pandian(2004), the stored energy can be converted to electricity for powering basic, low-power appliances such a lights, fans and the like [1]. The conceptof this study is the creation of a prototype of a seesaw togenerate power through pneumatics.

This study aimed to:1. Design a prototype2. Test the speed of compression of air from the pneumatic cylinders.3. Determine the charging and discharging time of the battery4. Design a controller circuit for the state of change of the batteries.

The study aimed to provide free lighting to playgrounds, parks and rural areas. Using the energy generated by seesaw, the energy from children’s play will be convertedinto usable energy. If this will be implemented to many parks and playground there will be great power savings.This will introduce a new source of renewable energy especially in this country.

The scope of this study is the generation of DC power bymeans of mechanical motion by the use of pneumatic cylinder installed in the seesaw. It will produce a small amount of power due to limited motion of the seesaw that is intended to supply only small lighting loads, particularlyLED’s(Light Emitting Diodes). The study focused on the usage of seesaw as the medium of the pneumatic cylindersand not in other playground equipment such a merry-gorounds and swings. Battery will be used as a storage device and the amplification of the energy stored will not be covered by the study.

2. 0 REVIEW OF RELATED LITERATUREPandian (2004) conducted a study about Human Power Conversion System based on children’s play. It proposed amethod for harnessing human power based on children’s play in playground and public places, and on devices such as seesaw, merry-go-round, and swing [1].

When large number of children play in playground, part ofpower of their play can be usefully harnessed resulting significant energy storage. This stored energy can then beconverted to electricity for powering basic, low-power appliances such as lights, fans, communications equipment, so on. The method provides a low-cost, low-resource means of generation of electricity, especially for use in developing countries. The paper discussed the basic theory behind the method. Results of experiments on a laboratory prototype compressed air human power conversion system using a teeter totter (seesaw) are presented to illustrate the practical effectiveness of the method proposed by Pandian.

This is related to the present study because the design will make use of motor and generator to produce electricity.The concept of converting energy through motor and generator is important in this study.

2.3 Pneumatic CylinderPneumatic Cylinders offer a straight rectilinear motion tomechanical elements. Cylinders are classified as light, medium, and heavy duty with respect to their application.Selection of materials for cylinder components may depend greatly on this factor. Functionally, cylinders may be single acting and double acting. The piston rod of cylinders is given special treatment as it is a highly stressed part. For cylinder lubrication, mist lubrication is most common. To generate rotary motion, air motors may also be used. Vane type motors are more popular. Air motors have certain specific advantages over electrical motors. Proper maintenance of cylinders, motors, and various air-operated hand tools enhance their life expectancy to a great extent. The pneumatic power is converted to straight line reciprocating motions by pneumatic cylinders. A single acting cylinder, the compressed air is fed only in one side.Hence, this cylinder can produce work only in one direction. The return movement of the piston is affected by a built-in spring or by application of an external force. The spring is designed to return the piston to its initial position with a sufficiently high speed [4].

Figure 1. Parts of a Single Acting Pneumatic Cylinder. (1) Cylinder(tube); (2) End Cover; (3) Piston; (4) Piston rod; (5) U-cap seal; (6) O-ring; (7) Bush; and (8) Spring

The Pneumatic Cylinder will be used as the main component of collecting energy from the seesaw. A singleacting cylinder will be connected to the seesaw for the compressed air.

limited energy from ambient heat, light, or vibrations. Inmost of these conventional methods, users must focus their attention on power generation at the expense of other activities. However, for suitable electrical power generation, energy could be harvested from everyday activities such as walking, running or even dancing. In this paper, systems that use human power by walking and running are analysed, where an alternative system has been designed and implemented to generate energy from people dancing in a club environment. It shows that power from walking can be extracted using the ystem, i.e., maximum 80-100W to an average of 20-30 W over a period of 10 seconds. This previous study is related to the present study because it showed that normal human activities can be used to generate electricity. In here, the previous researchers presented the amount of energy that can produced by a dance floor.

Last 2008, a design student Daniel Sheridan has created asimple seesaw which generates enough electricity to light a classroom. The device works by transferring the power,created by a child moving up and down on it, an electricitystorage unit via an underground cable. He has calculatedthat five to ten minutes use on seesaw could generate enough electricity enough to light a classroom for an evening, for example. Many schools in Africa open their doors in the evening to much older pupils but are only tolight their classrooms with candles or kerosene lamps [2].This article discussed the feasibility of generating useful energy from seesaw. It was used to power classrooms in the previous design, while the present researchers will use it to power lightings on playground.

2.2 Motor and GeneratorEngineers call electric motors and generators “electricalmachines”. The reason for this more general term is thesame device may operate either as a motor or as a generator. Electrical machines convert mechanical energy into electrical energy.

When conversion is from electrical to mechanical, the machine is called a motor. When it is being used to convert from mechanical energy to electrical energy, the machine is called a generator. The advantage offered by DC machines is their versatility. The ability to develop high starting and breaking torques, to make quick reversal of rotations, to maintain constant mechanical power output or to maintain constant torque and to permit continuous speed variation over a range as large as 4:1, make DC motors better suited to many industrial applications [3].

Technical Feature


2.4 Energy Storage A battery is a device that can store energy in a chemical form and then convert into electrical energy when needed.

There are two fundamental types of chemical storage batteries: The rechargeable or secondary cell, and the nonrechargeable, or primary cell. In terms of storing energy or discharging electricity,, they are similar. The Battery is comprised of at least one but possibly many cells appropriately connected and these cells are where the actual action storage and discharge takes place. All electrochemical cells consist of two electrodes separated by some distance. The space between the electrodes is filled with an electrolyte which is an ionic liquid that conducts electricity. One electrode is the anode and it permits electrons to flow out of it. The other electrode is the cathode which receives the electrodes. The energy is stored in the particular compounds that make up the anode, cathode and the electrolyte such as zinc, copper, and SO4, respectively. Series and parallel connections of batteries are the options to increase the Ampere-Hour capacity or voltage and even both in accordance to what is needed. Ampere-Hours are normally used to indicate the amount of energy a storage battery can deliver [5].

The Battery will serve as the storage device of the design. It will be the source of supply for the lighting loads. The connections of the battery, parallel or series may be considered to increase either the voltage of the Ampere-hour capacity of the storage device.

2.5 MicrocontrollersA microcontroller is a single device which follows instructions, reads information, stores information communicates, measures time, and switches things on and off. It also does other things, depending on the model. If you are the type of person who likes to take thing apart you will find microcontroller in all kinds of places. The most common place is under the hood of almost any car produced since 1985. Consumer items include televisions, compact disc players, washing machines, telephones, and microwave oven. Office computers use microcontroller in addition to their main processor to control peripherals such as keyboards and printers. Automated manufacturing systems use microcontrollers in production equipment such as robots and conveyor lines [6]. This study made use of microcontroller to regulate the flow of voltage for battery storage.

2.6 Air Pressure EngineAir pressure engines are employed as motive force. From the extreme lightness and mobility of air, it has been frequently proposed to employ it as a medium for transmitting motion to machinery at a considerable distance from the prime mover. Among the first who attempted this is the celebrated Papin, who invented the steel-yard safety-valve. He employed a fall of water to compress the air in a cylinder, through the medium of an intervening piston and he connected this cylinder to another, at the mouth of a mine a mile distant, by means of a pipe of that length. In the second cylinder was another piston, the rod of which was intended to work a set of pump; but, contrary to expectation, the compression of the air in the first cylinder produced no movement in the piston of the second. Papin subsequently attempted to bring his scheme into use in England, but did not succeed. Afterwards, however, he erected great machines in Auvergne and Westphalia for draining mines, but so far from being effective machines, they would not even begin to move. He attributed the failure to the quantity of air in the pipe, which must be condensed before it can condense the air in the remote cylinder he therefore diminished the size of this pipe, and made his water machine exhaust instead of condense, and had no doubt that the immense velocity with which air rushes into a void, would make a rapid and effectual communication of power. But the machine stood still as before. Near a century after this, an engineer at an ironfoundry in Wales erected a machine at a powerful fall of water, which worked a set of cylinder bellows, the blowtype of which was conducted to the distance of a mile and a half, where it was applied to a blast furnace; but notwithstanding every care to make the conducting pipe very air-tight, of great size, and as smooth as possible, it would hardly blow out a candle. The failure was ascribed to the impossibility of making the pipe air-tight, but above ten minutes elapsed after the action of the piston in the bellows, before the least wind could be perceived at the end of the pipe, whereas the engineer calculated that the interval would not exceed six seconds. The foregoing particulars are taken from Dr. Robinson’s Natural Philosophy, art [8]. Air pressure engines will be used to rotate the generator. Concepts behind the air pressure engines and how it works is important.

3.0 EXPERIMENTAL SECTION

3.1 MaterialsIn creating the system, the following materials were used(refer to Figures 3 to 9) : Pneumatic Cylinder, check valve,

Technical Feature


hose, air tank, pressure gauges, FRL, air motor, DC generator, battery. According to Figure 2, for the whole system, the materials were connected together to form the seesaw. Additional fittings were added for compatibility of the materials connected. Some of the parts of the system were brought second hand. The air tank was bought from a shop of unused tank of compressor. The tank does not have specification but, based on the measurement, the tank has a volume of 4.5 gallons. Another material that was bought second hand is the air motor; the motor was from unused car buffing tool. The generator was bought second hand. There are no available specifications, but it produces 12 V, however, through testing, the specification were determined. As this study went along, the design of the system was also modified. One of the modifications is the removal of the flywheel from the original design of the system. Though the implementation of the flywheel proves to prolong the amount of time that will be added to the back-up charging the batteries.

3.2 ProcedureOne of the determining factors in this study is the rate at which children play. This is essential because the average amount children play the seesaw will affect the charging time and capacity of the battery. The number of children in the seesaw is exposed may also be considered but that will not be focused of the study. To be able to compute the time a battery charges is dependent on how many cycles an average play the seesaw can be made in a given time.Based from Tables 1, 2 and 3, it can be observed that from10 to 600 psi, the higher the pressure, the higher the time and number of cycles it takes for the air pressure to increase by 5 psi. Also, if there are two pairs playing the seesaw, there are minimal difference in the number of cycles compared to the number of cycles if only one pair is playing. But there is a significant difference in the number of hours the tank can be filled. The researchers

tested the number of cycles made playing the seesaw in slow, average and fast play.Figure 8. Car

The number of cycles it takes to fill the tank depends on the area of the cylinder. Also, the amount of air that enters the tanks depends mainly on the volume of air where the pneumatic cylinder travels. To prove the researcher claimed that: due to testing, the fitted pressure of air tank drives the air motor to produce 14.4 V to 15 is 60 psi.

5.0 CONCLUSIONBased from the results the system, the seesaw energy contrapment system generates small but significant amount of electrical energy which can be stored to a battery and can be used for lighting loads. The addition of the seesaw in the solar panel is a good auxiliary source of power and can be implemented to compensate the powergeneration and the charging of the battery system. Furtherdevelopment of the system is highly recommended in order to increase the power generation efficiency. Pneumatics as energy converters can also be applied in

The number of cycles it takes to fill the tank depends on the area of the cylinder. Also, the amount of air that entersthe tanks depends mainly on the volume of air where thepneumatic cylinder travels. To prove the researcher claimed that: due to testing, the fitted pressure of air tank drives the air motor to produce 14.4 V to 15 is 60 psi. An excel program was used to determine the number of cycles for the tank to reach 60 psi. The result of 117 cycles is close to the actual cycles of 139 cycles. Figure 11 shows the testing of the voltage generated by the generator. Using this, the number of cycles can also be expressed mathematically by the given equation:

Where:f –number of cycles (frequency);K-pressure constant;Troom-room temperature;Penv-atmospheric pressure (1atm);V-volume per cycle;q-cylinder capacity

4.0 RESULTS AND DISCUSSIONFigure 12 shows the relationship of pressure and time. The group conducted six trials, starting with 80 psi up to 30 psi. The higher the pressure, the longer the time will it take drain the tank. Figure 13 shows the characteristics ofvoltage and pressure. As pressure rises, the voltage is heldconstant. The pressure for this graph is at the tank side. Figure 14 shows the characteristics of current and pressure. As pressure rises, the current is held constant. The pressure for this graph is plotted also at the tank side. Figure 15 shows that at regulated output pressure (14 psi), the behaviour of voltage is constant. But the current shows an erratic behaviour due to the sudden decrease in pressure.

various playground equipment such as seesaw, swing, and etc. Also, the charge controller is essential in regulating the energy collected from the system.

6.0 RECOMMENDATIONSLong air tubes are also losses in air pressure transmission leading to longer time to reach the prescribed pressure. Increasing the number of seesaw with the prescribed system can also improve the time for filling the tank, increasing the time of the rotation of the air motor, thus, longer time for the generator to produce power. If the said recommendations are considered for the system, higher power generation efficiency is expected.

Microbial Fuel CellA Renewable Source of Energy: Pasig River Sediments for Lighting

By: Benedict D. Daisog, Enrico M. Dela Cruz, Alvin Rene L. Salazar, Jayson U. Tisca, Gilbert J. Crobillo, Neko E. Taneo

As the international community calls for a clean and renewable source of energy due to the treat of the effect of climate change, a lot of effort had been made to find ways to develop existing clean source of energy as well as finding a new type of renewable energy which shall sustain the energy needs of the world. Also, the economic aspect of these renewable source of energy had been taken into great concern to be a much better substitute to the existing source of energy primarily fossil fuel.

And one of these types of clean energy source which at the moment is still in its infancy is utilizing bacteria as source of energy now called the Microbial Fuel Cell. And in the Philippines where there is an existing energy crisis, such alternative sources of energy are very much in need today. Also, because of the pollution in the major rivers and bodies of water in the country, this type of alternative energy shall provide a long term goal in utilizing such bodies of water which have an abundant source of bacteria making it suitable for the microbial fuel cell technology. Like the Pasig River, the major river system in Metro Manila which is in fact highly polluted with organic materials make it a huge den of different types and species of electricity producing bacteria. Because of this aspect, the group had seen that the Pasig River is not only for transportation purposes but also for providing a clean source of energy by using the bacteria mostly concentrated in its sediments.

More so, bacteria in nature mostly have the purpose of decomposing waste product of nature itself for the completion of life cycle. Because of this natural process the nature have, Bacteria used battery using Pasig River sediments can be sustainable and cheap source of energy for the country.

Floating Electric Generator

This presentation presents part of the work carried out within the framework of a research project entitled Floating Electric Generator. Specifically, it is focused on the activities performed in order to achieve one of the main objectives of the project: the design of a generator for a run-of-river to use the plentiful water source to build an easy-to-install, low-cost and safe hydroelectric power generation apparatus.

Hydroelectric power generation is a way of generating electric power by converting potential energy and kinetic energy of water into electric energy. At present, there are different methods of achieving the hydroelectric power generation, and one of the methods is to construct a dam and install a hydroelectric generator for the electric power generation. However, this method incurs unusually high expenses for the construction of the dam, and the dam also damages the natural landscape and ecology, and thus less and less dams are built now. Another method is to build a pumped-storage hydroelectric plant including two water storage pools built at upstream and downstream locations of a river respectively. During off-peak hours, water is pumped from the downstream water pool to the upstream water pool for the recycle and reuse of the water. However, the expense required for building such hydroelectric power generation plant is very high. Another famous hydroelectric power generation method is to build a large underwater turbine at a riverbed, and tides are used for driving the turbine to rotate. However, the construction of the underwater turbine at the waterbed incurs tremendous efforts and high costs, which are not cost-effective, and the operation of the turbine at the waterbed not only gives rise to a high level of difficulty for the maintenance, but it also has a safety concern.

With this project, we can preserve the nature at the same time maximize our renewable energy sources. Using renewable energy is a central aim in the world, because it helps to reduce CO2 emissions, it enhances sustainability and it also improves the security of energy supply by reducing the growing dependence on imported energy sources.

ENERCON(Enery Conversion Grill)

By: Edward Robert C. Dee, Paul Timothy R. Mabilangan

Grilling is a form of cooking that involves dry heat (electric gas, charcoal) applied to the surface of food, commonly from above and below. Grilling usually involves quite a lot of direct, radiant heat and tends to be used for cooking meat quickly and meat that has already cut into slices. It is widely used nowadays because of the taste that it gives to the food such as the smoke taste of a grilled barbeque. In some coutries like the United States, they commonly use gas of electric grills because of its portability and it is more convenient. Here in the Philippines, we use charcoal for grilling because it is more economical. And as the grilling business grows exponentially in the Philippines, a lot of waste heat is being dissipated day by day on a 24 hour basis. The waste heat being present in the system is not utilized properly by these companies. A device called peltier device is a thermoelectric device capable of harnessing and converting direct heat present in the grill into electrical energy suitable for powering different kinds of loads. Aside from thermoelectricity, conventional way of converting energy such as wind to electricity will be efficient to power up different loads present in the grill for maximum utilization.

from the member’s point of view

“Will the future scarcity of EE Instructors lead to scarcity of EE Professionals?”

Without EE instructors there would be no EE students. For those who aspire to be an electrical engineer, educators serve the bridge that connects between their dreams and reality. Educators lay the foundation for the structure; they inculcate the basic and the complex. In the academic paradigm, the applications of concepts, theories, and laws are taught to strengthen the students’ competitiveness after graduation. A student’s professional construct, at the most, relies on the knowledge and the abilities of the educators to hammer down the raw materials.

While it’s true, of course, the task should be two-way. In State Universities, it is the instructor's goal to inform the students’ responsibilities in nation building. Students must understand that because their education is funded by the taxpayers, they must be part of the solution and not the problem. All industries and households rely on electricity so students must also be motivated in strengthening our economy. Ergo, instructors do not only teach technicalities of the course but also the responsibilities of being a state scholar. An instructor’s role requires hard work, passion and integrity.

Being part of the academe has enticed few since 0.5% of graduates would walk towards this path. Of course there is an assumption that after acquiring license, an electrical engineer should practice their skills in the industry (corporation and government agencies), where they can assure themselves of financial stability. There is this contagious mind-set that electrical engineers are supposed to be trained of the dirty works in the industry to be able to sharpen and mostly choose to rather not be involved in the hands-on lacks of the academe profession. It also adds up that for careerists, such job is a dead end which does not promote career growth at all.

Another point of argument is the relative low compensation and few to none benefits relative to the profession in state universities. This mere fact results to the increasing vacant

professorial seats in the academe. In economics, scarcity means a problem; it is a looming specter. Logically, if there is no sufficient voltage the machines would not function. Yes, there is a need to increase the number of EE instructors to fill in the vacancies. If you ask me, a campaign is imperative to drive the interests of our youth traversing the Electrical Engineering profession. For instance, qualified conversant professionals can do a part time instructional job whilst being a full time industry employee. The importance of EE instructors must be stressed. Also, we must address the need to increase the wage and add non-monetary benefits. But to attain a positive corollary, it is a must that those who will fill in the position are beyond qualified. In a sense, it is important that the one person must be familiar with teaching methodologies. Ergo, prospective instructors must also undergo training programs to strengthen their teaching skills. We must remember that quality and quantity is directly correlated to the success of the institution to produce competitive professionals.

Since points have been raised, it is imperative that we analyze the root cause of the scarcity and qualification. In recent years, the government has not increased the budget for education. The state has been clear that it had been campaigning to lessen the number of state universities. Obviously, with insufficient budget allocations it is almost close to impossible to ask for more financial support. Would this lead towards an irresolvable conundrum? I don’t think so. Being part of the academe, I believe that since we have recognized the problems and have formulated possible solutions, we must continuously assert our right. Our institution has produced scholars and we have to produce more. Our government must be startled by the specter that hounds our college. We have to assert and reaffirm our fundamental right since what we are fighting for is for the nation's benefit.

Thus, I have to rephrase my first statement, without the abundance of competitive EE instructors, there would be a scarcity of competitive and efficient EE professionals.
