With The Wind: Woven Wind Turbines

Members : K. Cruz, Gascon, Mendoza, Orosa, J. Que, Quitangon, Sale

The world’s population is constantly consuming non-renewable energy that is destroying the Earth. Non-renewable energy which is the main source of power of the people’s daily use of technology, is slowly getting consumed to its last few sources. Renewable energy was introduced to remedy the current problem; renewable energy makes use of natural renewable sources like, the sun, water and wind and these sources will not run out and will remain constant on earth. A good example of a Renewable energy is the “Wind Turbines” where wind mills harness the power of the wind and transform it into energy for homes. “Wind Turbines” have been innovated to suit the needs for sustainable development of developing countries.

The Technology

“Wind turbines are used to generate electricity from the kinetic power of the wind” (“Wind Turbines”). At first, they were used for more practical purposes as a mechanical device to operate certain machineries but in the past decade, it has evolved to be utilized for energy production. In its current iterations, there are two main kinds of modern wind turbines. These are the Vertical Axis Wind Turbines (VAWT) and the Horizontal Axis Wind Turbines (HAWT), both of which, although fundamentally the same, operate differently. This technology is used to produce large amounts of electricity in wind farms both onshore and offshore, but the same concept has been applied for small-scale enterprises such as households as a renewable energy solution. Such enterprise is the Women Wind Weavers of Guatemala who create small wind turbines woven from traditional and high-strength fabric.

        The potential of wind power has also given a unique opportunity to the impoverished weavers of Guatemala. Using new technologies developed by ATC and the University of Michigan’s BLUElab, the various artisans within Guatemala have been given the chance to improve their quality of life and occupation by developing new wind-based energy generators using common textile weaving techniques. This is to be done by combining the technologies developed and provided by BLUElab with the weaving techniques of the artisans to produce textile-woven wind turbine blades that are to be efficient as the more conventional turbines being employed today. The generators to be produced are intended to provide clean energy for the impoverished families near to those who produce them, and the weaving process is to also provide a stable occupational monetary source for those involved for the weavers to earn their living in a more efficient manner as well. So far, the technologies are still in the development phase, as the structural and functioning frameworks for the most efficient turbine and generator designs have yet to be developed as the demands for the generators are to be easily maintainable and cheap to produce for the poor families. However, through public funding, education and perseverance, this project hopes to fulfill its ambitious goals to become a driving force by providing clean energy and occupations for those in need.

How It Works

In its large-scale iterations the two kinds of wind turbines have different characteristics that distinguish them apart as illustrated below:

7222842386_733a3eacc4_k.jpg

The most well known form is the horizontal wind turbines which is the basic framework used for the woven wind turbines. This turbine uses high-strength natural fibers to create fabrics that can be sustained for long term efficiency. The basic structure of how exactly it can be applied for home is shown in the illustration below. First, the wind turbine will be attached to the roof for maximum coverage. It will be connected to a charger or controller to power it, a battery bank to store excess energy, and an inverter to transport energy to the house electrical.

Thoughts and Insights

Sita-Weaving-Wind.jpg

Modern societies have become highly reliant on energy especially in businesses, industries and residences. With the uncontrollably increase in population, particularly in the cities this lead to an increase in consumption as well. It creates a significant pressure on infrastructure, housing, facilities, social services and utilities and as a result, many are experiencing shortages of electricity, natural gas, gasoline, kerosene and biomass.

In places where wind is very much available, a wind turbine might be the most economical and environmental-friendly way to generate power. The only wind power source in the Philippines is located on the foreshore of Bangui Bay in Ilocos Norte. So far, the Bangui wind farm helps alleviating power crisis by supplying 40% of the electrical energy in the region. In addition, Ilocos residents enjoy discounted power rates since the project will sell its electricity at a rate of 7% lower than the rate of National Power Corporation(NPC), and wind power is also not subject to the Expanded Value Added Tax (EVAT).

The use of wind turbines can be a great way to provide a source of clean and renewable energy for your home or business. There are a number of small wind energy devices that you can use to generate power and these can be very cost effective in providing a significant level of electricity. If you’re concerned about the environment and would like to make a difference then the use of a home wind turbine is a good place to start. Plus one must not worry for it is bird-friendly.

There are a lot of advantages using Wind energy. It does not produce any carbon dioxide; it is a clean fuel with no harmful by-products. It also makes a country more self-sufficient, less reliant on energy imports and less vulnerable to security threats. Renewable energy sources add diversity to energy supplies, providing a more dependable energy resource.

To find the solution, one must recognize the problem first. The first is unpredictable supply: the country’s economy has been faced with high and often unstable prices for energy, particularly for oil and gas, combined with supply disruptions caused by political instability.. The second reason is the rising demand: rapid industrialization and impressive economic growth are increasing the use of oil. This leads to increase living standards in which energy shortages could be met by increasing supplies. But there are two other important considerations: environmental sustainability and social development. The current pattern of economic growth has caused serious environmental damage such as polluting the air, creating large quantities of waste, degrading biological systems and accelerating climate change. Almost everything comes from the effect of energy sector. At the same time, it is also necessary to consider the impact on social development. The lack of access to energy services intensifies many social concerns, including poverty, ill‑health, unemployment and inequity.

It is not a secret that almost every individual still depends on inefficient and highly polluting solid fuels for their everyday household energy needs, in particular coal and biomass such as wood, animal dung, and crop wastes. The growth in energy use has serious environmental implications. Apart from depleting energy resources it can cause environmental damage, such as greenhouse gas(GHG) emissions, air pollution, acid rain, loss of biodiversity and discharges of waste. That’s why we suggest that the government and renewable gas companies should focus on developing wind power in our country, for the potential is already there all it needs is a little assistance and aid to become beneficial. “Any kind of ecological friendly produced electricity is an essential contribution to the protection of our environment and nature for forthcoming generations and it will stabilize or lower electricity prices (Mueller).”

Children with the personal version of the LifeStraw

It is difficult to believe that a country surrounded by water and abundant in marine resources is be prone to the threat of a water crisis. However, according to the Asian Development Bank’s Water Development Outlook report for 2013, the Philippines may experience a water crisis in the near future, if preventive measures are not taken soon (Ordinario, 2013). One of the components of the National Water Security Index used in the study is the resilience to water disasters (Ordinario, 2013). This factor plays a big role in evaluating the Philippine scenario because the Philippines is very prone to water-related disasters especially typhoons. The aftermath of Typhoon Yolanda shows that it is indeed possible for the lack of potable drinking water due to shortage and water contamination to be a rampant problem in affected areas. Though not highly publicized, one of the donations sent to aid the victims of Typhoon Yolanda was the LifeStraw, a special water filter that converts contaminated water into potable drinking water (Nicolasora, 2013).

ONE LAPTOP PER CHILD: Information for the next generation

The need for constant access to information is increasing, if not a requirement, in the modern world. It cannot be denied that for the most part, Internet connection is very essential for everyone if s/he wants to avail of the billions of information available online. As such, computers, or laptops for the modern day, are becoming a need for those who wish to be connected to the streams of information available.

The One Laptop Per Child program, the brainchild of faculty members at the MIT Media Lab, dreams of giving every student one laptop to help them in their pursuit of knowledge. The Delaware-based project laptop, costing $100 each (approx. Php4,500), aims to provide children all over the world with new opportunities to explore, experiment and express themselves.

Laptop Specs

Manufactured by Quanta Computers, the “$100 laptop” features a 700MHz AMD LX-Geode processor and 256 MB of Random Access Memory. This is enough for research tasks, word processing, and other educational computer work. In November 2007, the first large-scale release started, with the laptop running Fedora Core as its operating system and open-source software. Additional features are:

  • Dual mode display, SVGA LCD screen

  • Transmissive Color/DVD mode with 350×470 pixel resolution with backlighting (for laptop use)

  • Reflective “sunlight readable” monochrome mode with 800×600 pixel resolution (for ebook reading outdoors)

  • Minimal and practical software

In promoting the laptops, the manufacturers market them directly to ministers of education in order to directly distribute to their target recipients.

Figure 1. $100 Laptop (<http://olpc.com/pictures.html>)

 

Sustainability

OLPC focuses on fundraising efforts like launching websites and programs that help in promoting to the masses. Websites like Pentagram and Upstatement update customers with news about the project (OLPC Frequently Asked Questions).

Another initiative for sustainable development is the launch of the “Give 1 Get 1” (G1G1) program in 2007. It later established the laptopgiving.org website that accepts direct donations. The G1G1 offer started on November 12, 2007 and successfully extended until December 31, 2007. A second wave of the G1G1 program was launched the next year.

In terms of the OLPC’s environmental, the project aims to use eco-friendly materials as much as it could. The laptop and all OLPC-supplied accessories are fully compliant with the EU’s Restriction of Hazardous Substances Directive (RoHS).

Efficiency

The low-cost, environmentally-friendly laptops are fit for harsh weather conditions and rowdy environments. Made even for students in areas with no electricity, some versions of the $100 Laptop have cranks that allow its operation independent of a power source.

Every time they donate laptops to communities, OLPC ensures that all students are accounted for. No one is left out, allowing for the laptops’ standardized integration in the school curriculum and discouraging envy among the students.

Future

Seeing that OLPC is succeeding in making the public participate in the global enhancement of education, our group believes that the project will find its way in the ventures of other organizations and companies as well. More people will support this cause and as technology heightens, so will the capacity to reach out to more students all over the world, making knowledge easily accessible resource for anyone, most especially children.

Liwanag Sa Dilim: Illac Diaz’s One Liter of Light Project

A good example of an appropriate technology would be the solar bottle bulbs of the Isang Litrong Liwanag/Liter of Light project.

Photo from DW.de

The idea came from a Brazilian mechanic named Alfredo Moser, and was brought to the Philippines in 2011 through social innovator Illac Diaz’s MyShelter Foundation. In addition to the appeal of its ingenuity and sustainability, Diaz made the idea of manufacturing these solar bulbs even more attractive by introducing it as an industry from which the average worker can generate profit, and one that can effectively address a pressing need among poor households.

These 55-watt eco-friendly bulbs are very easy to make and install. All you need is a cleaned and sanded PET bottle filled with water and a few drops of ammonia, carefully cut 26-gauge galvanized steel sheets (yero), and an ample amount of epoxy glue. The top half of the bottle sticks out of the roof to catch sunlight, and the water inside the bottle simply refracts or bends this to brighten up the room in which it has been placed. The cap is sealed shut in order to ensure that the water won’t evaporate, while the ammonia prevents the water inside from getting contaminated by algae. The putty lining that joins the bottle and the steel sheet keeps the contraption from falling apart. Of course, the bottle works only in the daytime, but it’s definitely better than nothing.

Photo from Positivo.com

Illac intends to bring this idea to the world, saying that he wants Filipinos to benefit and profit from this innovation, rather than simply being beneficiaries. To help the idea grow sustainably, the “local entrepreneur” model has been adopted. The solar bottles are not mass produced in large factories but are hand-made in local communities. Detainees of the Makati City Jail, for example, earn P8.00 for every solar light bulb they produce. This model also forgoes the environmental waste incurred by concentrating production in one large factory.

Solar bottles emit zero carbon and are more cost-effective and sustainable than incandescent or LED light bulbs. The substitution of incandescent bulbs to solar bottles showed a substantial decrease in accumulated Greenhouse Gas emissions over its 5-year lifetime. The materials for the bottles are also readily available in the communities, forgoing the need for manufacturing and transporting new bottles to areas of production. In addition to this, the money saved by families from using solar bottles instead of electric light bulbs can be used to attend to other needs, such as sending children to school.

This project has provided a sustainable light source for classrooms in rural areas and impoverished villages in the metro, helping mothers and children work or study more effectively inside their homes. The installation of the solar bottles would significantly decrease fire-related incidents caused by illegal electric connections in slum areas.

Isang Litrong Liwanag has brightened lives of many Filipinos and they intend to bring light to 4 more million homes in 4 different continents in the coming years.

A Future that’s Bright, Clear…and Round?

For centuries, sunlight has been used in photosynthesis, drying clothes or rice, and growing crops, however, recently it has been used for solar power. Solar power is basically the power obtained by harnessing the light from the sun. But how do solar panels absorb sunlight and turn it into electricity? Made from layers of silicon, PV cells produce electricity whenever sunlight shines on it, creating an electric field across the layers. PV cells vary in shape and size, but panels usually placed on top of an existing roof are the ones commonly used, or solar tiles.

The Rawlemon devices track the movement of the sun

         The concept of Spherical Solar generator is the brainchild of Architect Andre Broessel of Rawlemon. This project uses the advantageous strategy of using a spherical lens to concentrate sunlight on a small photovoltaic panel and combines this with a dual-axis pivot that tracks the movement of the sun. By function, it is quite similar to the traditional solar flat panels but by concentrating the sun’s light in one area, it reduces the solar cell surface required. It is conceptualized to be able to harness solar energy from the sun, the moon, or even the gray sky of a cloudy day. The use of the transparent lens, it would be possible for this technology to be integrated to buildings, walls, etc.

Spherical solar generators are considered to be “appropriate technologies” since it uses an efficient and renewable energy resource, the sun. Well, renewable energy is not an entirely new concept, but it is slowly emerging as an alternative to fossil fuels and, hopefully, other detrimental energy sources. Harnessing the energy of the sun is within our grasp, and for developing countries, this is great opportunity for change. Solar power is an increasing market which is also good for the environment because it replaces the traditional, and in effect harmful, methods of energy production. Reasons for choosing solar energy are also becoming clearly because of the extensive research being conducted in this field, solar panels are developing into more efficient models than ever.

Henceforth, this new form of solar power technology is a breakthrough in solar power science for it exploits light’s characteristic of being reflected by ‘concentrating’ the light on to one particular spot. It is a huge step forward from the most advanced solar power generator before it, which merely tried to track the sun’s rays but at the same time, causing it to be really faulty in the occurrence of bad weather. Apart from this, this technology economically uses less solar cells, a costly technology. Lastly, the spherical structure allows the technology to absorb light even from sources such as the moon or from sunlight during that of a cloudy day’s.

Start Living Green and Saving Green With www.GreenerDawn.comThe Philippines is at an advantage geographically given that it is located close to the equator and receives more sunlight than in other regions of the world all year round. Given the steady incline of improvements and advancements of solar technology, it would be beneficial for the Philippines as a developing country to make use of solar energy and eventually, if possible, run purely on solar energy when the technology further develops to be economical, affordable, and with this new innovation, we’ll be one step closer to reaching a future of solar power and energy.

Exploring Appropriate Technologies: The Solar Light Bulb

By: Angeles, Ereñeta, Jeng, Litam, Montenegro, Segui, Tuason

           “Appropriate Technology (AT)” is a term coined by Dr. Ernst Friedrich “Fritz” Schumacher that refers to the ideological movement which utilizes technology in an energy-efficient, environment friendly, low-cost, and labor-intensive manner; geared towards the improvement of the standard of living in the developing world. Various cultural, social, and ethical aspects are put into deep consideration when creating new ideas for appropriate technology. One notable example, which has proven to be effective and useful in many developing countries, including the Philippines, is the solar light bulb.

Blog5

THE SOLAR LIGHT BULB

           The first solar light bulb, Nokero’s N100 was designed to “create more light using the ultimate light source”. The bulb is engaged in an ultra-rugged, rainproof enclosure which can supply up to 4 hours of light when completely charged. It is made from impact resistant plastic, as well as solar panels, LEDs and a replaceable nickel metal hydride battery, which lasts for up to 2 years. When it is exposed under solar energy, it is able to trap enough juice to yield illumination for roughly 2 hours.

           The bulb works like regular solar technologies; it is left under the sun for its four solar panels to absorb radiation which will be converted to and used as energy. It is designed to hang outdoors in order for the panels to charge the batteries and then to be used later on at night. It has the feature of automatically turning off in an environment of bright light to conserve charge, but it also has the option of an On/Off switch. The purpose of having batteries allows the light bulb to be used when the owner requires or pleases rather than immediately after charge, and the batteries are replaceable so that the bulb itself may last a long period of time. It is overall durable and rainproof with less chances of overheating since the batteries were made to withstand higher or lower than normal temperatures (-20 to 55 degrees Celsius).

Effectiveness

           The solar powered light bulb allows people living in rural areas to continue working even during late hours. There has been an increase in the economic activity levels of villages where these light bulbs have been installed. Many areas that do not have electricity use kerosene lamps, but fumes from kerosene lamps are harmful to both health and the environment. The solar light bulb helps address these issues. Kerosene lamps are also incredibly dangerous and are serious fire hazards. The solar light bulb, on the other hand, is completely safe. Not only that, but the solar light bulb saves energy and reduces air pollution and greenhouse gases as photovoltaic systems do not emit carbon dioxide while producing electrical power. With the use of these light bulbs, quality of life is improved in rural areas and migration to urban cities is prevented. Maintenance is a lot easier compared to kerosene lamps and diesel generators that constantly need to be refueled and maintained. Lastly, Literacy and school work are also improved as people can more easily read in the dark with a solar light bulb rather than by candle or lamp light.

Impact on Sustainable Development

           When talking about impacts on sustainable development, it is important to know what and how much resources it takes to create and operate a technological product. With the solar light bulb, the main resource that this technology consumes is solar power, as it is powered using 4 solar panels that energize its nickel metal hydride battery. With regard to solar power as a resource, it is virtually infinite so long as the sun is visible.

           The International Institute for Sustainable Development defines sustainable development as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs.” The solar light bulb addresses one of the essential needs of the world’s poor, which is the need for light, without compromising the needs of future generations. At the same time, it also addresses the concept of limitations. According to its product description, the solar light bulb was made for “developing nations where continual electricity is a mere pipe dream.” Because of its dependence on solar power, developing nations have a chance to have a steady light source even without the presence of continual electricity.

IMPACT ON SOCIETY

           Many households all over Africa need light to perform their activities but daily life and work are often disrupted with the setting of the sun.  With no way of obtaining light, many Africans live in darkness and are often forced to use fossil fuels. With the help of the solar powered light bulb, many African households will be able to live comfortably and continue their work even after the sun has set.

           In Medor, Haiti, education is important to many of its residents, but education is difficult without sufficient light and electricity. Sue Carlson, Chair of the Haiti Committee of Our Lady Queen of Peace in Arlington, VA, decided to solve this problem by providing each student in the 12th and 13th grades with a solar powered light bulb. The light has provided students with the opportunity to study more outside of school. This has made a huge difference in the lives of the students as many of them have gone on to college and few have entered law and medical school under full scholarships.

           In November of 2013, just days after the Philippines was hit by Typhoon Yolanda/Haiyan, which left thousands of Filipinos without food, water, shelter, or electricity, Nokero decided to launch the Solar Relief Campaign. The goal of the campaign is to provide victims with light as they try to restore their homes and towns. Without electricity, there is delay in the reconstruction and restoration because of the long, dark nights. Numerous non-profit organizations joined the campaign and purchased light bulbs to be distributed in devastated areas. The light bulbs have been well received and appreciated by the typhoon victims. Over 4,000 light bulbs have been distributed in Tacloban, Leyte, Samar, etc., and the campaign continues to bring light, comfort, and hope to many Filipinos affected by the typhoon.

           Because of the great demand for light and the effectivity of this technology, the use of solar lights has grown immensely throughout the years. In fact, there is now an organization which aims to improve quality of life by providing “clean and healthy lighting” through the distribution of one million solar lights across different nations in the globe. This is the non-profit organization, One Million Lights. Solar lighting has been found to be a clean, safe, and affordable means to provide light in many rural communities. As of April 2013, the organization had already distributed 37,561 solar lights in 27 countries throughout Africa, Asia, and the Americas.

           In the Philippines, One Million Lights has already distributed 5,372 lights across many provinces. The Philippine Star writes, “They have changed these barangays… with the fervor of their idealism and with solar-powered lamps.” (2013) Indeed, solar lights have not only served a great purpose to Mother Earth, but have also significantly improved education, livelihood, household work, etc. in places that need light.

INTO THE FUTURE                                                  

           Solar technology is not new to the world, yet it is only now that the advantages it provides are being noticed. In the case of the solar powered light bulb, the fact that it is the source of light for developing countries shows that it isn’t simply just a means of saving on electrical energy but a channel to give what many lack. The ability to harness the sun’s radiation and convert it into energy opens up new doors for world’s future. Nokero has also been manufacturing solar battery chargers for cellular phones, a sign that this technology is not limited to producing light. The solar light bulb is one of the ingenious inventions which are able to cater to basic human needs, another example being a solar water purifier. Perhaps the light bulb could be advanced in the future in order for it to last longer than its current state. Perhaps most houses could be required to have half their lighting systems use solar light in order to cut costs and electricity use. At this point, the solar light bulb can develop in numerous directions, but one thing that’s for sure is that this amazing and very appropriate technology has a bright future ahead.
