Nomadic Entrepreneurs: A New Generation Fueled By the Sun

Thursday, July 16th, 2009

As a child, she tended yaks and goats on the mountainsides of rural Qinghai, China but things have changed since then. She still considers herself a nomad. Now, however, she is a nomad of business and it is solar panels and solar cookers she tends.

Dorma (卓玛) rose in the business world by migrating from trade to trade and from city to city; wherever opportunity presented itself. She is one of the few women of her ethnicity to run her own non-restaurant business.

One Earth Designs recently visited Dorma’s factory with local university students to negotiate solar technology prices. Seventy watt solar panels cost 2,000 RMB (293 USD) and 8 watt solar panels cost 400 RMB (58 USD).

As for solar cookers, China has a handful of standard designs that you can read about here. Dorma sells the two most popular designs:

(1) Concrete Butterfly Solar Cooker:

Butterfly solar cookers are asymmetric parabolas. In this solar cooker, the asymmetric parabolic dish is made from concrete. Small mirrors (usually 1”x 1”) are then pasted on the surface of the concrete parabola using tar or silicon adhesive. The base of the cooker is a circular concrete slab.

  • Cost: 150-200 RMB (22-29 USD) + tax + shipping
  • Weight: 95kg (209 lbs)
  • Long Distance Transportation: 20% breakage in route to the villages
  • Collection Area: 1.88 m2
  • Reflector: Both tar and silicon glue lose efficacy when exposed to weathering. If mirrors are not placed tightly together, these glues melt and the mirrors fall off within a few weeks to a few months.
  • Assembly Time: 20 minutes
  • Boil Time/5L water (summer): 10 minutes, sunny day (30 C ambient; 86 F)
  • Boil Time/5L water (winter): 2.5 hours, sunny day (-15 C ambient; 5 F)
  • Accidents:
    • Starts unwanted fires
    • Burns through pots
  • Cooking: Fast but cooks food unevenly

(2) Cast Iron Butterfly Solar Cooker

This is also an asymmetric parabolic solar cooker. The dish is made from two cast iron wings that unscrew for separate transportation. Mylar is pasted on the surface to boost specular reflectivity. Standard paper glue is used as the adhesive. The base is designed like a wheelbarrow in order to increase portability.

  • Cost: 420-500 RMB (62-74 USD) + tax + shipping
  • Collection Area: 1.62 m2 (0.81 per wing)
  • Weight: 70 kg
  • Long Distance Transportation: Mylar often tears during transport to villages.
  • Reflector: Pasting Mylar leaves many bubbles and insufficiently pasted edges which tear easily during transportation and weathering.
  • Assembly Time: 5-10 minutes
  • Boil Times: Slightly less than concrete cooker
  • Cooking: Fast but cooks food unevenly

Although Dorma sells these cookers, she does not manufacture them. We went to visit solar cooker factories in Gansu, Sichuan, and Qinghai in order to compare prices and profit margins. Here, we report these values for the concrete solar cooker (only the government manufactures metal cookers as the unsubsidized cost of purchasing them is prohibitively expensive for most households).

The total price of manufacturing a concrete solar cooker averaged 84 RMB (12 USD). Profit margins for the factory owner ranged from 36 to 116 RMB (5-17 USD).

Many factory workers had recently relocated to urban centers from the countryside. Workers laying mirrors were able to make 6 cookers per day, thus earning 36 RMB (5 USD). If they work 7 days per week every day of the year they can make slightly more than 2/3rds China’s average urban income. The workers we spoke with had bandages covering cuts on their fingers from the edges of the glass mirrors.

Workers laying concrete were able to make 13-15 cookers per day, thus earning 39-45 RMB (6-7 USD). If they work every day of the year, they earn a few hundred RMB short of China’s average urban income.

One Earth Designs is inspired by Dorma’s success and saddened by the low wages and poor working conditions faced by rural peoples relocating to urban areas (those few able to find city jobs). We are working with local development organizations, universities, and communities to nurture a new generation of nomadic entrepreneurs skilled at merging traditional design practices and materials with modern needs and urban capacities.

Stay tuned for an introduction to our novel solar cooker design, the SolSource 3-in-1, and its potential as a local income generator.

Small and Beautiful: The Engineer within Us All

Tuesday, June 30th, 2009

The innovations that gave birth to the world’s ancient civilizations are fading into dust.

The Greater Tragedy: Not only are we losing the knowledge and inventions that first allowed humans to adapt to life in the world’s great deserts and on its snow-capped mountains, but the communities responsible for these innovations now feel ashamed of them.

In many regions, advertisements of foreign cities and technologies have generated a sense of inferiority that has discouraged even the most talented traditional craftspeople from continuing their trades.

Nowhere in the dialogue are these traditional lines of innovation labeled ‘science’ or ‘engineering’. Instead, they are called ‘history’, ‘art’, or ‘culture’, put in museums rather than studied in workshops. The great irrigation systems of the Incas that allowed them to flood the Ollantaytambo valley (Peru), drowning their conquistador rivals, have not made their way into contemporary texts on sustainable agriculture.

Our task is to inspire confidence within communities to recognize the contemporary usefulness and future potential of their design traditions. We do not want to preserve cultures, but rather to reinvigorate them.

Although all our efforts aim towards this goal, one is deserving of special attention, our engineering workshops run by One Earth Design’s (OED’s) Chief Engineer, Amy Qian.

Amy Qian holds up disassembled early SolSource 3-in-1 prototype in MITERS.

The daughter of two computer scientists, Qian began her career as a mechanical engineer as an eight year old; by whittling pointy sticks in her backyard. She graduated to carpentry with power tools in her garage, then to the metal shops of her high school and the robot building laboratories of MIT (Media Lab).

Qian’s passion for practice and design has never waivered because “it has given [her] the power to build tangible solutions for the problems [she is] presented with”. Now, she is working to inspire that same passion in others and to empower those around her to engineer solutions for their own communities.

Last week, Qian held a series of design workshops that seemed to be destined for failure. A landslide blocked her way into the city for the workshop, forcing her to spend an extra hour crossing the nearby river and finding a car to take her the rest of the way. At the markets, none of the vendors wanted to sell a duffel-bag full of wood to a woman, and for various reasons the location of the workshop had to be changed three times just hours before the sessions began.

Finally, the group gathered. The son and daughter of a carpenter who had been sent away to school as young children, two women’s group leaders from farming families, and a nomadic man who started a rural education association huddled around Qian, listening attentively to her explanations of wood working tools and design principles. Then, they built.

This is what they had to say after completing the woodworking portion of the workshop:

This is a small start but, to us, it is a beautiful one.

ICTD: Supporting Local Solutions and Living Cultures

Wednesday, June 24th, 2009

It all started with three small seeds, teachers in a provincial university in China. One teacher loved music, another photography, and a third writing. Their passion and dedication inspired generations of students to pursue these arts and the Plateau Cultural Initiative (PCI) was born.

The Plateau Cultural Initiative

The Plateau Cultural Initiative

With used cameras, recorders, and computers in hand, PCI’s students have found ways of keeping their diverse cultures alive by documenting knowledge that is being lost, and by seeking ways to employ these traditional wisdoms in adapting to changing global circumstances.

For the past two days, we have been teaching these students how to build their own websites so that they can display their work. Although it took us years to learn HTML, CSS, and PHP, these students—many of whom have only recently learned how to use computers—were able to understand the process of making a website and creating content of their own with remarkable speed. One student had already mastered six human languages (Kham, Amdo, Namuyi, Yi, Mandarin, and English) when he entered our workshop and is now well on his way to adding three computer languages to his repertoire.

Although the students were excellent, we realized that our teaching left much to be desired. We found our initial lecture-style workshop format to be ineffective. Employing smaller topic-based work stations with hands-on activities proved a better method. The topics we covered were:

How to start a simple Website:
1) Rent a domain name
2) Rent server web space from a web host
3) Decide on a content management system and install it
4) Transfer information to servers
5) Download a website theme
6) Enter Content
7) HTML, CSS, and PHP for content and theme manipulation

[Our instructional materials (videos, screenshots, and handouts) will be posted on our website shortly. We are interested in working with others to develop good training materials. Please send us suggestions.]

Hard economic times have hit rural students, like PCI’s members, the hardest. With few job opportunities, one student wrote, “Seeing so many unemployed graduated students in the past made me realize that I must have a skill that others don’t have in order to find a job and I must help others know that I have this skill by making a website”.

Many students also wanted to help the world know more about their local traditions and ways of life. They were sad to see things changing so fast and to realize that so much of their grandparents’ knowledge has not been passed on to their parents.

Still more students wanted to create new knowledge through online tools. One student is working to create an online tagging system for four languages not included in the global forum. A team of students will work together to translate Wikipedia into local languages. One student will work to create an online learning platform for languages currently not taught by mainstream texts. Another student wants to develop a market price transparency system and use cell phone SMS messaging to ensure that rural farmers can sell their produce for a fair price.

Some may wonder why I wrote ICT for D in the title of this post. We are not inventing new communication technologies nor distributing cell phones to rural communities that never had them before. Instead, the goal of these workshops is to teach people how to use communication technologies to create their own online tools; ones that can help them implement local solutions and exchange ideas globally.

The Plateau Cultural Initiative is struggling to stay alive in today’s difficult economic climate. You can help by:

1) Donating your used cameras, recorders, and computers
2) Hosting an exhibition of their photographs, music, and writing
3) Financially supporting their work

Please contact me if you are interested in helping out in any of these ways, and stay tuned for links to PCI’s up-and-coming websites!

Origin in the Himalayas

Wednesday, June 10th, 2009

Frozen, the terraced fields appeared as silver cascades descending the mountainsides and ice crept, crackling, up the trunk of the village’s lone tree. Although there was no snow (many habitable regions of the Himalayas are known as high-altitude deserts), everything was frozen including the feces in the village’s newly built latrines. This is what had brought us to the village.

Frozen world

The anger was palpable as we took our places in the village leader’s house alongside the council of elders. The villagers had decided to raise money to install the latrines because an NGO had told them that going to the bathroom outside was the cause of the recent increase in childhood diarrhea. The villager’s raised half the money and the NGO built the latrines. In the winter, however, the villagers were still forced to go to the bathroom outside because the latrine’s evacuation doors were too small to allow the removal of the frozen feces. The villagers wanted to know how to build their own latrines so that they didn’t need to rely on what they saw as foreign incompetence. They had heard that we could help.

^^^

I first visited this region in 2001, but it was the words of a young woman whom I met in 2007 that stuck in my mind and led me to co-found One Earth Designs along with Scot Frank.

“When I was little”, she said. “I asked my mother why she was so short. She told me that I too would be short because of the heavy burdens of fuel and water that we women carry.”

As the young woman showed me around her village, I realized that her words did not just describe the water jugs and dung baskets that women hauled up the mountain to their homes. Women also carried the burden of lung disease from their smoky stoves and the burden of caring for their children who frequently had diarrhea from contaminated water. In addition, long hours spent collecting these daily necessities prevented women from improving their social stature because they had no time to attend school.

In the barter economy, all members of the household had contributed to subsistence. With the arrival of the cash economy, however, women had been left with time consuming chores while men became the money makers. Life was difficult because families only had one primary income earner.

For agricultural villages, life was even more difficult in the seasons when the sleet came early, unexpectedly, and ruined all the crops. It had happened more and more in recent years and some of the villagers had begun to whisper that the earth would end soon. People had angered the elements and soon the great storms would come to break the earth apart.

For the nomadic clans, it was the little rabbit-like pika that diminished livelihoods. With the warming climate, pika had migrated to higher elevations, eating the grasslands and leaving little food for the yak herds and sheep flocks. The destruction of the grasslands also meant a decrease in the dung and wild brush that had served as the traditional fuels.

nomadic life in N. India

The specifics were different, but I had seen this before in the high-altitude communities of the Andes, the Townships of South Africa, and the lowlands of Brazil, India, and Vietnam. Global trade had changed the social structures of communities, global climate change had drastically altered the environments around them, and global industry had led local governments to try—often brutally—to rid their countries of ‘unsightly’ things such as the rural way of life and the slums on the outskirts of cities.

The controversial economist, Julian Simon, wrote that global population growth was a good thing because it meant more minds to innovate better solutions. But the communities that I am describing have largely been excluded from global solution making. Given the long history of innovation in the Himalayan region, I wanted to know why so many villages were seeking help from outside rather than innovating independently.

The answers I received came down to a matter of confidence. People were well aware of the hardships of their own lives. The images of foreign technologies and lifestyles, on the other hand, always looked so glamorous and happy. By comparison, rural Himalayan communities felt inferior. People no longer believed in their ability to build, fix, innovate, and understand the world around them because their culture and its knowledge had been so challenged and degraded by a rather one-sided dialogue with the outside.

Scot Frank and I co-founded One Earth Designs in order to complete this dialogue and inspire confidence in local innovation as a way forward in a rapidly changing world. We have also found ourselves gaining confidence through this work, confidence in the human ability to help each other in the way that we each wish to be helped, and confidence to believe in a better world no matter how many times our lives or egos are threatened along the way. As Jacqueline Novogratz, founder of the Acumen Fund, wrote in her book, The Blue Sweater (2009), local “ownership of the dream” lies at the core of positive change.

One Earth Designs: Democratizing Science and Engineering

Monday, June 8th, 2009

In a recent meeting with Oxfam, one public health official summarized for me conclusions drawn from their 2005-2008 research program evaluating disaster aid operations in regions of India and Sri Lanka devastated by the 2004 Tsunami. The central finding, he said, was that communities wanted more ownership.

“From study after study, a theme emerged. It was like a drumbeat, faint and barely recognizable at first, and then louder and louder as the findings rolled in. It didn’t seem to matter what the topic of the research was. Its underlying message was nearly always the same: disaster-affected communities wanted a chance to guide their own recovery – and humanitarian programs (would) probably work better if they (did) so.” – Oxfam 2009 Report

Oxfam was speaking of a people impoverished by war and natural disaster, but the same is true of all communities. Readers may shrug this off as being an obvious and easy task, but it is not. For communities struggling to adapt to rapidly changing circumstances that they themselves have had no say in, reclaiming the self-confidence to decide how to proceed into the future can often be more daunting than simply continuing to live amidst life-threatening conditions. Our job as change-makers is not to make decisions on behalf of these communities once disasters have struck, but to maintain a steady effort to empower people with the self-confidence to make change themselves.

One Earth Designs aims to do this by democratizing science and engineering. This summer we are focusing our efforts on four programs:

The SolSource 3-in-1 (initiated in 2007) is a solar cooking, heating, and electricity-generating device developed in conjunction with Himalayan villagers who were interested in designing a more portable solar cooker that would still be wind-sturdy and capable of stir-frying. This summer we will be working with recently urbanized communities to refine the manufacture of this device for local income generation. Find out more on WorldChanging, Discovery Channel, and the SolSource website. You can also follow updates on twitter.

HeatSource Textiles (initiate in 2009) offer a renewable means of staying warm at sub-zero temperatures and were developed in conjunction with Himalayan pastoralists who found that climate change was rapidly eradicating their traditional means of staying warm during herding. The design employs the phase change properties of locally-available materials to provide a mobile form of energy storage and controlled heat delivery. The textiles are fully reusable and can also be recharged with solar energy when people aren’t wearing them. Find out more on the HeatSource website and follow it on twitter.

The Global Citizen Water Initiative (Citizen Water) (initiated in 2008) works with NGOs, universities, and health clinics to teach villagers how to test their own water sources using simple, inexpensive kits. The results of these tests help match water sources with appropriate local treatment providers. In addition, the initiative’s website—although still in the development phase—will provide an online map of this data for use by researchers and health regulators. Find out more on the Citizen Water website and follow it on twitter. [Funders: Google.org, Tides Foundation, MIT TauBetaPi, MIT IDEAS, the Baruch Family, Legatum Center]

We are also developing an illustrated Applied Science and Engineering Reader Series (ASER) for rural schools with chapters on topics such as waste management, water quality, indoor air pollution, latrines, solar cookers, greenhouses, and water treatment/supply methods. Find out more on the ASER website.

The task of enabling others to make their own change is as frustrating as it is intangible. This work cannot be accomplished by handing out food or money, nor through infrastructure development or technology transfer alone. It requires a deep respect between people. Most of all, it requires a willingness to work and learn alongside one another and from each other.
