An Austrian baker teamed up with One Earth Designs this week to test two internationally manufactured solar cookers, the CooKit and the HotPot, in a small agricultural village on the Himalayan plateau (2700 meters (9000 ft) in elevation).
The Qualitative Results:
The Austrian baker, Michaela Borghese, was able to make one delectable cake (on the HotPot), some bread (on the CooKit), vegetables (on the HotPot) and Austrian potato dumplings (on the HotPot).

The CooKit attracted many admirers, including the village goats who found its cardboard frame quite appetizing.

The Quantitative Results:
Simultaneous water boiling tests were performed to compare these two solar cookers. Each cooker was used to boil 1L of water. In the case of the HotPot, the standard black bottomed, clear glass topped pot was used. In the case of the CooKit, an un-blackened stainless steel pot with a diameter of 10 inches and a height of 7.5 inches was employed contained within a plastic oven bag.
The boiling point at the test elevation and barometric pressure was 91.6°C, the ambient temperature ranged from 18°C to 24.15°C during the tests, and the average solar irradiance was 865 W/m2.
The HotPot was able to boil 1L of water in 1 hour and 39 minutes (see graph below). The dip in the curve occurred when the pot was opened to add dumplings.

If we assume a 1m2 effective reflector area and negligible conduction losses, the efficiency of the HotPot reflector is 7.16%.
E = (Qw - Ql)/(Ac)*(Ia)
Where:E = % EfficiencyQw = Power supplied to water to raise water temperature (w)Ql = Power lost through pot conduction (w)Ac = Effective collector area (m2)Ia = Average actual solar irradiance (w/m2)The CooKit was not able to boil the 1L of water. Its water temperature peaked at 79.6°C after 3 hours and 19 minutes.

We previously tested the HotPot and the CooKit in both nomadic and agricultural regions (2500-4500 m.a.s.l (8,200 ft - 14,800 ft)) during winter clear sky conditions. Bellow 5°C ambient temperature, neither was able to boil water. Windy conditions also greatly reduced their efficiency.
Putting the Data in Context:
The performance of the HotPot and CooKit during summer and winter tests suggest that neither is well-suited for use in regions where fast, high temperature cooking is preferred. Although the HotPot was able to cook a wide range of foods under summer clear-sky conditions, none of these foods are eaten in W. China where stir-frying and boiling tea or soup water are the primary cooking techniques. The HotPot's 1.5 hour boiling time for 1L of water is considered too long by local women who are able to boil 5L of water in 5-20 minutes on their stoves and existing solar cookers (see "Nomadic Entrepreneurs: A New Generation Fueled by the Sun" for more info on current W. China solar cookers). The CooKit's inability to boil water even under the best summer conditions suggests that it is similarly ill-suited to this region.
On a positive note, the temperatures achieved by the HotPot and CooKit under Himalayan conditions suggests their wide applicability in regions where stewed foods are popular. Indeed, there already exists much evidence of their success in such regions.
About the Instruments:
During these tests, temperature was measured using Maxim iButton Thermochrons. Water temperatures were measured using DS1922T iButtons (Range:0 to 125 C) encased in DS9107 waterproof capsules. Ambient temperatures were measured using DS1922L iButtons (Range: -40 to 85 C). We’ve been using these for a while and have compared them against a variety of thermocouples with excellent performance results. We highly recommend them.
Solar irradiance was measured using a MicroCircuit Labs DSL-1 Solar Data Logger (this cost $160 but, if you don’t need a logger, MicroCircuit Labs also sells a build-it-yourself irradiance meter for only $24.95). So far, the performance has been quite good but we haven’t been using it for long so we may have more to say later.

Marmots once dug their homes in deep holes across the Himalayan plateau, helping turn over the soil and creating the grassland's most important water reservoirs. Now, they are being hunted for their skins. Piles of rocks speckle the mountainsides where marmots scratched futilely against the solid rock in an attempt to escape their hunters. The grassland moisture is drying up. The plains are becoming desert.
Yesterday, I wrote that rats ("grass rats" in Chinese) had infected humans here in Qinghai with the black plague. That translation was incorrect. The vector species were marmots. Currently, it is believed that the disease took two routes of transmission: (1) street dogs eating a dead marmot and infecting goats who later died from the plague and infected the man who buried them and (2) fleas transmitted from marmots to humans during poaching activities.
China has long been known as the breeding ground for the worlds' most dangerous and widespread diseases. Each year, the US designs its flu vaccines based on new strains found in China. Why?
One possible answer is that China has a high population of animals and humans living in close proximity to one another, often with minimal infrastructure to restrict cross-transmission of diseases.
The Chinese government and NGOs have pumped a lot of resources into improving rural infrastructure. They have installed running water projects, built clinics, manufactured solar cookers, and distributed thousands of improved stoves. Despite these admirable efforts, W. China's rates of death and illness due to water and airborne diseases remain some of the highest in the world (with unofficial numbers likely to be much much greater due to the shear difficulty of getting health care out to China's rural masses).
Perhaps the solution does not lie in infrastructure development alone. China needs doctors to staff its clinics and public health professionals to design preventative medicine programs. It needs engineers and locals to work together to design pollution management systems which break the cycle of disease transmission and it needs scientists who can help prevent the ecosystem imbalances which have been associated with so many disease outbreaks including historical cases of the pneumonic and bubonic plagues.
Humans worldwide need to reconsider the basic way that we interact with our environment, reduce our environmental pollution, and create healthy living spaces for ourselves as well as the animals and plants upon which we depend.

Some say that solar cookers and solar panels pull the sun down from the sky and that this can cause evil in the world. Others say that humans should use the sun, as plants do, to live and grow without polluting the sky gods’ kingdom with black smoke.
The SolSource 3-in-1 was born from this second desire. It harnesses the suns’ energy for cooking, heating, and electricity generation without pulling it from the sky.
The initial concept for the SolSource solar cooker platform was born out of a memory relayed by a Ladakhi nomad.
“The colors of our land are changing. The land was once a vast expanse of green grasses dotted with black tents. Now it is a desert of yellow and white.
When I was a child, we would move our black yak tents from place to place and only leave a small pile of white ashes on the ground where we had been. Now, my children think it is better to live in a white synthetic tent and leave the ground covered with yellow plastic. They think that everything from the outside is better than what we make even when it doesn’t work as well…like the synthetic tents that let in all the cold air and have to be replaced every two years.”
The Himalayan terrain is one of the harshest on Earth and its inhabitants have displayed incredible ingenuity in adapting to that environment, sheltered by their woven yak-hair tents which last for 20 years and whose fibers swell to keep out the rain.
The design of the SolSource Cooker through close collaboration among villagers, students, and development workers, is an attempt to continue a traditional line of local innovation. It merges design principles of traditional nomadic tents with those of synthetic high-altitude hiking tents to produce a light-weight, portable, and weather hardy solar concentrator that enables the maximum range of cooking styles including stir-frying.
Field tests have yielded 28% efficiency compared to 20% efficiency of butterfly cookers tested simultaneously. The most recent iteration of the SolSource solar cooker reduced its weight to 6 kg. Although staking down the bamboo legs gives the device excellent stability against the wind, many villagers thought that it was too light and were worried that it would not last long under windy conditions. We plan to revert to several elements of our previous prototype design which bring the weight of the device to 8 kg.
The other element that we changed during our recent tests was the design of our thermoelectric component. The feedback was that the previous prototype which was slightly less efficient but which allowed people to boil water while also generating electricity was highly preferred by villagers.
We have partnered with four communities to begin local manufacture and income generation of the SolSource 3-in-1 over the next year.

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 + shippingWeight: 95kg (209 lbs)Long Distance Transportation: 20% breakage in route to the villagesCollection Area: 1.88 m2Reflector: 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 minutesBoil Time/5L water (summer): 5-20 minutes, sunny day (30 C ambient; 86 F)Boil Time/5L water (winter): 2.5 hours, sunny day (-15 C ambient; 5 F)Accidents: Unwanted FiresCooking: 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 + shippingCollection Area: 1.62 m2 (0.81 per wing)Weight: 70 kgLong 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 minutesBoil Times: Slightly less than concrete cookerCooking: Fast but cooks food unevenlyAlthough 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.

Good Technology vs. Good Implementation: Recently, a paper was written which greatly offended our friends and partners in China. The paper described local grassroots efforts as being less effective than those made by One Earth Designs and other foreign-led groups because locals ‘lacked the technical ability to create sustainable infrastructure’. This is an opinion that we have heard voiced by many international development workers. BUT creating sustainable change requires much more than just good technology.
My favorite example is a set of greenhouses that one foreign aid organization built here in Qinghai. The organization didn’t tell the villagers how to use them so, instead of growing crops, the villagers stored their motorcycles inside so that the motors would start more easily in the winter.
Without an understanding of the social, economic, political, cultural, and environmental contexts of a region; without both listening to constituents and teaching about new ideas; without follow-through and continuity; and without scalability, development projects (no matter their technical excellence) are doomed to failure.
Informed Impact & Local Students’ Efforts: Unlike foreign-based organizations, local groups have a much deeper understanding of and greater ability to meet these conditions.
In western China, they have done so. Thousands of rural communities have accessed tap water, adopted cleaner cooking technologies, revised farming practices, and built schools with libraries through student and community led grass-roots efforts. A few examples are Shamo Thar’s Development Program at Qinghai Normal University, Pentok, The Bridge Fund (TBF), the Jinpa Trust, the Friendship Charity Association, the Normgo Education Association, and the Snowland Service Group.
Communities and grass-roots development groups have built a wealth of sustainable social and physical infrastructure by implementing their own solutions and reaching out to others (whether neighboring communities or aid organizations) for any additional resources they need along the way.
In fact, it is only when local groups need project funding, technical capacity building, or confidence to act based on local knowledge (even when others might put them down for doing so) that foreign-led groups are any use at all. One Earth Designs aims to build confidence and technical capacity in the arenas of science and engineering, but our impact is by no means comparable to that achieved by the teachers, students, and communities who really run the show.
Foreign Students’ Efforts: The offending paper was written by a student ‘changemaker' visiting Qinghai for just one month. While the author cannot be blamed for misunderstanding the dynamics of local development efforts, s/he should be held accountable for acting upon misconceptions. The same holds true for all student changemakers.
Social entrepreneurship and sustainable development are popular terms among US students. But, although the US university community offers many resources to help students become changemakers (in their own communities or abroad), few turn talk into action. Many of those who do take action fail to understand the communities they work with or to ensure project continuity beyond the 1-3 months of their involvement.
Even worse, I have often heard students lying to the communities with which they are working. I once heard an Engineers Without Borders (EWB) regional staff member counsel local chapters to ‘tell communities that [they] will return regardless of whether or not [they] actually will’ because it ‘fosters a sense of trust’. [NOTE: This does not reflect on EWB as a whole. I have personally witnessed many good outcomes of work done by EWB members]
Students who really want to make change can start out with three steps. First, they can learn from the mistakes and successes of other students doing development projects. Skill-building conferences such as the Global Engagement Summit (GES) at Northwestern University, the International Development Design Summit (IDDS) hosted by MIT, and Clinton Global Initiative University's (CGIU’s) annual student conference are just a few of the great opportunities in this vein. Second, students should spend time travelling and living in the region where they hope to make positive impact. Third, students should learn how they can best help directly from their partner communities.
Sensitivity & Academic Integrity Abroad: Lastly, please make every effort not to jeopardize the lives or work of your community partners.
As changemakers, your actions have the potential to create great positive impact in the world. The positive nature of this impact, however, hinges on your intentions. If your intentions are sincere, they will lead you to respect and connect deeply with those around you. By doing so, you will naturally find a way to do good things in the world.

September 2008 was the first time I came to Honduras on behalf of Global Brigades. I spent the first full day in the country completely immersed in communities, learning first hand the operations of our Health programs. The night before our trip into the communities I spent packing bags of medicine with our Medical Brigades chapter from the University of Washington. Over and over again, I counted the same quantity of pills to be separated into plastic bags and labeled with dosages. I also sat with a Public Health Brigades chapter as they reviewed the method for constructing ecostoves. I watched the excitement of the groups as they prepped all night for their first day out in the field.
The next day we was long and exhilarating. I spent the first couple of hours helping a Medical and Dental brigade set-up and sat back to watch dozens of community members line up to be seen by our doctors. I was astonished to hear that some women had walked over 3 hours to receive something as simple as tylenol. The process was very structured, you walk up to intake, give your name and information, go into triage to have your blood pressure and other stats taken, then see a doctor who proscribes you and sends you to the pharmacy station to pick up your meds. Yet, something that one would see as simple is the difference between life and death for some of these people.
After being completel awed by the Medical brigade, I then spent time with a Public Health brigade team as the constructed ecostoves for some of the people in the same village. After seeing hundreds of patients, Global Brigades saw that a large problem in these communities is respiratory related, and after spending time in the communities, they saw that it mostly came from the stoves that were being used. With lack of access to information or education, some people in the communities don't realize that the smoke being trapped causes their respiratory problems, and more so the design of their stoves takes an excess amount of wood and a long time for cooking. To combat this problem, Public Health Brigades was formed to find solutions to problems like this; to build ecostoves, latrines, and any thing else that could help these communities.
A few months before I came to Honduras I went to a event hosted by the Seattle Microfinance with our CEO of Global Brigades. The event was showcasing a Seattle-based organization called Microenergy Credits. The firm bundles carbon credits for different non-profits so that they can be sold on the carbon credit market. After listening to their presentation, we instantly knew that our Public Health program could benefit from their services. Now, only a few months later and after a few emails and phone calls, we are beginning to track our ecostoves in our communities to start receiving carbon credits. We have to continuously make sure that the ecostoves we put in place are working, and we randomly get audited once a year. However, with some of our communities being hours away, and with the number of ecostoves being implemented growing exponentially, how do we track everything? What is the most effective way to make sure that the ecostoves are working and so that they money received from the carbon credits is worth all the tracking?

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 prototype of the
SolSource 3-in-1. Photo: Scot Frank.
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.

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
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 workPlease 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!

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.

Catlin Powers and Drogar Jyid with SolSource 3-in-1 [Photo by Scot Frank]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. [Funders: Lemelson-MIT International Technology Award]

HeatSource TextilesThe 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]
Drogar Jyid runs Citizen Water training seminar [Photo by Scot Frank]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.
