Solar Bottle Bulbs Light Up Dark Homes

Finding ways to generate low-cost or free light has captured the imagination of innovators across the global South. The desire for light is strong: Light gives an immediate boost to income-making opportunities and quality of life when the sun goes down or in dark homes with few windows.

More than 1.7 billion people around the world have no domestic electricity supply, of whom more than 500 million live in sub-Saharan Africa (World Bank). Without a source of electricity, it is difficult to use conventional technology to switch the lights on.

While it is possible to run lights using batteries or diesel generators, these are expensive options that are not possible for many poor people. The more of a slim income that is spent on light, heat or cooking fuel, the less there is left for better-quality food, clothing, transport or education and skills development.

Low-cost light is great, but free light is even better – and one Brazilian solution is offering this.

Brazilian innovator and mechanic Alfredo Moser has taken the common plastic water bottle and created a low-cost lighting solution for dark spaces. Often makeshift homes lack decent lighting or a good design that lets the light in during the day. This means it may be a bright, sunny day outside, but inside the home or workplace, it is very dark and reading or working is difficult.

Moser came upon the idea during regular blackouts in his home city of Uberaba (http://www.uberaba.mg.gov.br/portal/principal) in southern Brazil during 2002. During the blackouts, only factories were able to get electricity, leaving the rest of the population in the dark.

The “Moser Light” involves taking plastic bottles, which are usually just thrown away or recycled, and filling them with water and bleach to draw on a basic physical phenomenon: the refraction of sunlight when it passes through a water-based medium.

It is a simple idea: Holes are drilled in the ceiling of a room and the bottles placed in the holes. The liquid-filled bottle amplifies the existing sunlight (or even moonlight) and projects it into the dark room. This turns the plastic bottle into a very bright lightbulb that does not require any electricity.

Moser uses a solution of two capfuls of bleach added to the water to prevent anything growing in the water such as algae because of the exposure to sunlight.

“The cleaner the bottle, the better,” he said.

Polyester resin is used to seal the hole around the plastic bottle and make it watertight from rain.

Moser claims his bottle innovation can produce between 40 and 60 watts of light.

Moser uses recycled plastic bottles, so the carbon footprint is minimal compared to the manufacture of one incandescent bulb, which takes 0.45 kilograms of CO2 (UN). Running a 50 Watt incandescent light bulb for 14 hours a day for a year, around the same light as produced by the bottle bulb, produces a carbon footprint of nearly 200 kilograms of CO2.

“There was one man who installed the lights and within a month he had saved enough to pay for the essential things for his child, who was about to be born. Can you imagine?” Moser told the BBC.

The plan is to try and get as many as a million homes fitted with the lighting system by the end of 2013.

In many poor areas, it is common to live in makeshift or rudimentary dwellings. These are often built to crude designs and, in order to keep costs down and boost security, will have few or no windows. These dwellings will consequently be very dark inside, even on the brightest days. This leaves people having to turn to a source of artificial light if they want to do something indoors like read or work. And this costs money. Be it electricity from a mains, or battery-powered lamps or gas-powered lanterns, the cost will eat into a person’s tight income. This is where Moser’s simple solution saves the day and saves pennies: it is free light once the bottle lamp system is installed.

Placing the bottle lights in the ceiling transforms the ceiling into something akin to the night sky, with many points of light shining down into the room like stars. It also means the occupant of the room does not just have to strain to see with the use of a single light but now has many lights illuminating the room from all angles.

“It’s a divine light,” Moser told the BBC World Service. “God gave the sun to everyone, and light is for everyone. Whoever wants it saves money. You can’t get an electric shock from it, and it doesn’t cost a penny.”

It has not been a road to riches for Moser. He has made some money installing the system in a local supermarket and nearby homes, and he has inspired a charity to install the lighting system and to train people to do the installation and make an income from it.

The MyShelter Foundation in the Philippines was inspired by Moser’s invention and has installed the system in some 140,000 homes there, the BBC reported.

“We want him to know that there are a great number of people who admire what he is doing,” MyShelter Executive Director Illac Angelo Diaz said of Moser.

Using bottle bulbs instead of electricity or generators means families can save US $6 per month, according to Diaz (CNN). The Philippines is reported to have the most expensive electricity in Asia and slum homes usually do not have electricity.

It is estimated 15 other countries also have homes using the Moser system. The MyShelter Foundation believes 1 million homes worldwide have used the Moser system as of 2013.

Liter of Light (http://aliteroflight.org), run by the MyShelter Foundation, offers instructions on how to install the lighting system on its website.

Solar Solution to Lack of Electricity in Africa

 

Electricity is critical to improving human development and living standards. Yet, for many in the global South, electricity is either non-existent or its provision is patchy, erratic, unreliable or expensive.

Just as Africa has been able to jump a generation ahead when it comes to communications through the mass adoption of mobile phones – a much cheaper option than trying to provide telephone wires and cables across the continent – so it could also bypass the burdensome costs of providing electricity mains to everyone by turning to smaller electricity generation technologies such as solar power. This is called “off-grid” electricity.

The UN has set the goal of universal access to modern energy services by 2030. A report issued in April 2010 by United Nations Secretary-General Ban Ki-moon’s Advisory Group on Energy and Climate Change (AGECC) calls for expanding energy access to more than 2 billion people (http://www.unido.org/fileadmin/user_media/Publications/download/AGECCsummaryreport.pdf).

The report found that a lack of access to modern energy services represents a significant barrier to development. Some 1.6 billion people still lack access to electricity.

A reliable, affordable energy supply, the report says, is the key to economic growth and the achievement of the anti-poverty targets contained in the Millennium Development Goals.

When a person has electricity and the lighting it powers, it is possible to do business and study late into the night. Electric lighting also makes streets and living areas safer. Electricity can power a plethora of labour-saving and life-enhancing consumer goods: televisions, refrigerators, vacuum cleaners, air conditioners and fans, washing machines, clothes dryers, computers. And electricity recharges that most essential item, the mobile phone, on which millions rely to do their daily business.

After witnessing the struggle African health clinics have to access electricity, a Nairobi, Kenya-based company has developed a simple solution to ensure a steady supply of solar electricity. One Degree Solar’s (http://onedegreesolar.com/) founder, Gaurav Manchanda, developed and sells the BrightBox solar-charging system for lights, mobile phones, tablet computers and radios.

He first gained experience working in the West African nation of Liberia with the Clinton Health Access Initiative (http://www.clintonfoundation.org/main/our-work/by-initiative/clinton-health-access-initiative/about.html). Working at the country’s Ministry of Health, he found most health clinics operated without electricity.

He identified solar power as the only viable energy source. Trying to deliver fuel to power generators by the road network had two impediments: the diesel fuel was expensive and the road conditions were poor.

After seeing that large solar-power systems required significant maintenance and upkeep, he started to explore the possibility of low-cost, and simple-to-use solar electricity products that would be useful to community healthcare workers.

This became the beginning of One Degree Solar and its mission.

The company’s main product is the BrightBox, a cleverly designed solar charger. A bright orange box with a folding, aluminum handle at the top for easy carrying, it switches on and off simply with a bright red button. It has a waterproof solar panel. The BrightBox has USB (universal service bus) (http://en.wikipedia.org/wiki/Universal_Serial_Bus) ports so that mobile phones and radios can be plugged in. It is also possible to plug in four lights at once with the four outports on the side of the box.

It meets the standards set by the Lighting Africa initiative (http://lightingafrica.org/specs/one-degree-brightbox-2-.html) of the International Finance Corporation and the World Bank.

One Degree Solar claim it is possible to set up a BrightBox in 10 minutes. When the indicator light has turned green, the box is fully charged and capable of providing 40 hours of light.

A full charge can power two light bulbs for 20 hours. Manchanda told How We Made It In Africa (http://www.howwemadeitinafrica.com/) that he has sold 4,000 units of the BrightBox since its launch in October 2012.

According to The Nation, the BrightBox is currently retailing in Kenya for Kenyan shillings 7,000 (US $82).

One Degree Solar’s product range is sold to local resellers and distributors. The products are designed to be repaired using locally sourced parts and can be fixed by local electricians.

Most of the sales so far have been in Kenya but the firm has also sold units to other countries.

Testimonials on the BrightBox website tell of the transformation to people’s lives the clean energy source makes: “BrightBox has helped us in so many ways! We used to spend 800 Shillings (US $9.50) a month for two paraffin lanterns. The fumes smelled and always made us feel sick.”

Manchanda is a strong believer in Africa’s potential and its future and dismisses those who are negative about the continent.

“That was not a holistic assessment, but rather, an unnecessary and damaging generalization,” he told How We Made It In Africa. “Fortunately, most news outlets in Africa are now available online and offer a wider range of perspectives. The middle class is booming in certain countries. We have seen the success of mobile phones in enabling people to access other services. I think hope and progress come with innovation. Technology access has helped create entirely new markets and reach populations that otherwise could have taken decades to service with traditional approaches.

“India was in a similar space 15 years ago before the Internet boom, and today parts of Nairobi (Kenya) are just like Delhi (India): people have a cell phone or two, there are large shopping malls, a booming middle class, and new construction everywhere.”

Kenya Turns to Geothermal Energy for Electricity and Growth

 

In an effort to diversify its power supply and meet growing electricity demand, Kenya is looking to increase its use of geothermal energy sources (http://en.wikipedia.org/wiki/Geothermal_electricity). Tapping the abundant heat and steam that lurks underground to drive electric power plants offers a sustainable and long-term source of low-cost energy.

Kenya currently gets most of its electricity from hydroelectric projects. This is great until there is a drought, which there now is. With water resources low, the country has had to turn to fossil fuels to power electricity generators. This means relying on imported diesel, which is both expensive and polluting. It is also not generating enough electricity to keep up with demand.

Electricity blackouts have become common in the country and this is harming economic development. This is a particularly damaging setback in a country that has, in the last five years, gained a deserved reputation for its technological advances in mobile phone applications and Internet services – all needing reliable supplies of electricity.

Kenya is Africa’s largest geothermal producer and has geothermal resources concentrated near a giant volcanic crater in the Great Rift Valley with 14 fields reaching from Lake Magadi to Lake Turkana. There are also low temperature fields in Homa Hills and Massa Mukwe (http://www.gdc.co.ke/index.php?option=com_content&view=article&id=191&Itemid=163).

Kenya is expecting its gross domestic product (GDP) to grow by 10 per cent from 2012 onwards. The country hopes to become a middle income country by 2030.

Around 1,400 steam wells will be drilled by companies to meet these goals.

There are also many spin-off opportunities from tapping geothermal heat sources. These include using the steam heat for greenhouses growing plants, for cooling and heating buildings, and for drying and pasteurising foods.

Kenya is currently building a 52-megawatt (MW) geothermal project with funding from the United States government. It is also receiving US$149 million funding from the African Development Bank Group (AfDB) to build the Menengai Geothermal Development Project. This plant will be able to generate 400 megawatts of renewable electricity from the Menengai geothermal sources in the steam field located 180 kilometres northwest of the capital, Nairobi (http://www.gdc.co.ke/index.php?option=com_content&view=category&layout=blog&id=49&Itemid=137).

Speaking at a press conference this month, Gabriel Negatu, AfDB’s Regional Director, said he sees geothermal technology as an important driver of Kenya’s green growth ambition.

“Geothermal generation yields energy that is clean, affordable, reliable and scalable,” he said.

The Geothermal Development Company (GDC) (gdc.co.ke) is a state-owned company in Kenya and recently declared it had tapped steam with a well in the Menengai steam field. GDC started surface exploration in 2009 and has been using two drilling rigs to look for geothermal steam.

The Menengai Geothermal Development Project is slated to be completed by 2016 and will boost the country’s geothermal capability by 20 per cent. It is estimated to be able to power the electricity needs of 500,000 Kenyan households and power the needs of 300,000 small businesses.

Geothermal as a source of energy and electricity can help a country make big development gains. The best example is the Northern European island nation of Iceland. According to Orkustofnun (nea.is/geothermal), Iceland’s National Energy Authority, the country is a successful example of how a small, poor nation (Iceland was one of Europe’s poorest countries in the 20th century), shook off its dependence on burning peat and importing coal for its energy use. By 2007, Iceland was listed in the global Human Development Report as the country with the highest level of human development in the world. And one aspect of this success was the country’s ability to tap its renewable energy resources. Around 84 per cent of the country’s primary energy use comes from renewable resources, and 66 per cent of this is geothermal.

It is estimated Kenya could generate 7,000 megawatts of geothermal power and the Kenyan government is looking to increase the nation’s geothermal capacity from the current 198 MW to 1,700 MW by 2020 and 5,530 MW by 2031.

Indian Solar Economy Brings New Vocation for Women

 

India has started to make significant advances in developing solar power technologies for the poor. There are now whole villages using solar energy and improving their standard of living. Various companies and projects are selling inexpensive solar appliances – from cooking stoves to lanterns and power generators – across the country. This new solar power ‘grid’ is also bringing further economic opportunities: jobs for people to repair and maintain the new equipment.

An interesting initiative is turning the need to repair and maintain solar-powered equipment into a job opportunity for poor women.

More than 1.7 billion people around the world have no domestic electricity supply, of whom more than 500 million live in sub-Saharan Africa, and 400 million in India (World Bank). Some 600,000 Indian villages lack an electrical supply. India’s Prime Minister Manmohan Singh has pledged “power for all” by 2012. An ambitious goal, and one that acknowledges that without electricity, many development goals remain dreams that will never be achieved.

Being able to see at night, for example, unleashes a vast range of possibilities – such as being able to work or study later – but for the very poor, lighting is often the most expensive household expense, soaking up 10 to 15 percent of income.

The power of the sun can help transform this situation. According to Greenpeace (http://www.greenpeace.org/international), India could generate 10 percent of its electricity from solar power by 2030.

In the Indian State of Rajasthan, more than 30,000 homes in 800 villages have turned to solar power for lighting and cooking needs. It is this increasing solar power grid that the Barefoot College (http://www.barefootcollege.org) based in Tilonia – where it was founded over 30 years ago – has turned to as a new economic opportunity. The College is training women to be solar engineers, developing both useful skills and a new income source. So far, Barefoot College itself has solar electrified some 350 villages across India and dozens more in sub-Saharan Africa and even war-torn Afghanistan.

The College prides itself on stripping out academic jargon while inspiring confidence in students’ innate talents and skills so they can take on new vocations.

The solar engineers – many of whom are illiterate – are taught by their peers. Given a box of tools and hardware, the students undertake practical projects to learn-by-doing how the solar devices work and can be repaired. They are introduced to technical terms and concepts and learn how to wire circuits and do daily repairs.

“It is only, we have found, an illiterate woman who is a teacher who can actually train an illiterate women who is a trainer,” the college’s founder, Bunker Roy, told the BBC. “They have the patience, tolerance and improvisation.”

Roy says the training teaches more knowledge of the technical aspects of solar power than a typical student would glean from an undergraduate university degree.

The Barefoot College takes its inspiration from former Indian leader Mahatma Ghandi (http://en.wikipedia.org/wiki/Mohandas_Karamchand_Gandhi), who felt the wisdom, knowledge and skills already existing in rural villages should be the basis for any development. He also believed deploying sophisticated technology in poor communities should be done on their terms to avoid exploitation.

The College is a passionate believer in the inherent skills and abilities of the poor to improve their conditions. It eschews formal qualifications, believing these can be as much a hindrance as a help, trapping people in rigid methodologies.

The Barefoot College has been working on solar electrification in poor and rural villages since 1989. It has used similar techniques to train teachers and teach medical skills.

The course has successfully attracted sponsored students from as far away as Africa. Sarka Mussara, a 56-year-old widowed grandmother from the West African nation of Mauritania, had never attended school or even left her village before coming to India on a UN sponsorship.

“We started little by little learning the solar energy system,” she told PBS. “Day by day and little by little we were able to put things together.”

The solar engineers become highly skilled and can even fabricate complex components like a charge controller (http://en.wikipedia.org/wiki/Charge_controller) when they are back in the village.

One of the additional benefits of training skilled solar engineers is the more confident role these women play in their communities when they return. They often take the lead on other projects in the village.

The College also picks the tough cases: only villages that are inaccessible, remote or non-electrified get help.

Its approach is to have a meeting to introduce the benefits of solar lighting to the community. If the community wants it, then a village committee is formed. Any household that wants solar power has to pay a small fee, no matter how poor. This is to ensure they feel a sense of ownership of the new technology.

Some members of the community are then selected to be trained as “Barefoot Solar Engineers,” or BSEs. They will install, repair and maintain the solar lighting units for at least five years. A workshop is set up to carry out repairs fully equipped with tools and replacement parts. The solar engineers attend a six-month course at the College, leading to work for at least five years.

The Barefoot College encourages middle-aged women and widows and single mothers to become engineers. Experience has shown them to be the most reliable and less prone to moving to the city after training.

Indian Solar Power Pack Powers Villages

Developments in India are showing the way forward for low-cost solar power for the poor. The Duron Solar Home Power System (http://www.duronenergy.com/product_info/) is now enabling the rural poor to generate and store solar electricity. It is powerful enough to charge gadgets and appliances and run LED lights. It allows people to do their household chores into the dark hours and to study or earn extra income.

As the company says, it “allows ample light for cooking, for children to study at night, and for shop owners to stay open later to earn more money.”

The system removes the need for polluting and dangerous kerosene lamps, which are used by an estimated one million families for lighting in India.

Kerosene lamps are a major contributor to indoor air pollution, which itself claims the lives of 1.5 million people each year. Kerosene lamps have also caused countless deaths by suffocation, burns and fatal fires.

The United Nations Environment Program says kerosene fumes are responsible for around 64 percent of deaths for children under the age of five in developing countries.

More than 1.7 billion people around the world have no domestic electricity supply, of whom more than 500 million live in sub-Saharan Africa (World Bank). Some 400 million people in India do not have access to electricity, according to the World Bank, and 600,000 villages lack an electrical supply. Prime Minister Manmohan Singh has pledged “power for all” by 2012. Without electricity, many development goals remain dreams that will never be achieved.

Being able to see at night unleashes a vast range of possibilities, but for the very poor lighting is often the most expensive household expense, soaking up 10 to 15 percent of income.

According to Greenpeace (http://www.greenpeace.org/international/), India could generate 10 percent of its electricity from solar power by 2030.

The Duron package comes with a five watt solar panel, a cell phone charger connection, three LED (http://en.wikipedia.org/wiki/LED_lamp) lights, and an AC grid charger. After a day of charging, the Duron can power three hours of bright lighting or 10 hours of dim lighting.

The Duron system sells for about 5,999 rupees, or around US $130, and the typical user to date has been small businesses and schools.

Duron is selling several thousand units a month and the company is currently scaling up its sales efforts.

Duron’s approach is to provide a market solution to the huge problem of providing electricity to India’s rural poor.

The company was launched in 2008 with the goal of providing electricity to those without around the world. It was developed out of the Idea Lab (http://www.idealab.com/), a Pasadena, Californian incubator of technology companies.

Extensive field research was conducted across India to determine what was the best solution and what were the needs of rural dwellers. Duron moved its headquarters to Bangalore, India in 2009 to be closer to its customers and expand sales. The company operates in the Indian states of Uttar Pradesh and Karnataka.

By August 2009, more than 2,100 people had light because of the Duron system. The company calculates this translated into 172,500 hours of light.

One customer, Anil Singh, lives with his family in the unelectrified village of Narainpur. His family used kerosene lamps and was paying US $4 a day for unreliable lighting. But after seeing his neighbour, Santosh Singh, with bright, powerful lights at his home, he was curious as to why. When he found out about Duron’s system, he installed a system to light his front porch and two rooms in his house. His family now enjoys two-and-half hours of reliable light in the evening to do things.

“The Duron has made my life so much easier,” said Anil. “It’s a much cheaper (lighting) option compared to kerosene lamps, and I now have a reliable source of power on a daily basis,” he told the company’s website.

Another innovative start-up with offices in India and Africa, is the d.light company, which also has a new, highly-efficient solar-powered product available. The Kiran LED lamp (http://www.dlightdesign.com/products_kiran_global.php) stays lit for eight hours on a full battery and is four times brighter than a kerosene lamp. It illuminates 360 degrees and produces an even, bright white light.

Development Challenges, South-South Solutions was launched as an e-newsletter in 2006 by UNDP's South-South Cooperation Unit (now the United Nations Office for South-South Cooperation) based in New York, USA. It led on profiling the rise of the global South as an economic powerhouse and was one of the first regular publications to champion the global South's innovators, entrepreneurs, and pioneers. It tracked the key trends that are now so profoundly reshaping how development is seen and done. This includes the rapid take-up of mobile phones and information technology in the global South (as profiled in the first issue of magazine Southern Innovator), the move to becoming a majority urban world, a growing global innovator culture, and the plethora of solutions being developed in the global South to tackle its problems and improve living conditions and boost human development. The success of the e-newsletter led to the launch of the magazine Southern Innovator.
