3765 Plaza Drive Ann Arbor MI 48108 USA


The Appropriate Technology Collaborative (ATC) creates new sustainable technologies that promote economic growth and improve the quality of life for low income people worldwide. We design, develop, demonstrate and distribute affordable technological solutions that empower people and promote dignity. ATC works in collaboration with local talent and other nonprofits (NGOs) to create market-based solutions that are culturally sensitive, environmentally responsible and locally repairable in order to improve the quality of life and reduce adverse impacts on the environment.


Since our first project in 2007 we have designed a number of new technologies with much help from our local partners. Our first solar lights were built in Guatemala. We solar LED lights made from local recycled materials. We designed a Solar Vaccine Refrigerator (SVR) with students from Michigan State University. The SVR can be built almost anywhere in the world and depending on how it is constructed it can either keep vaccines cold or freeze ice packs to World Health Organization standards. The SVR has been built in many countries. We receive emails like the one quoted below: “Congratulation for saving millions of life(s) with your solar refrigerator project.” (Mr. Amit Kumar Singh – East of Uttar Pradesh, India) We work with several Colleges and Universities to help students understand the complexities of creating Social Ventures in less/least economically developed countries. We introduce students to some of the problems we and our clients have identified and we help student teams work in Guatemala, Nicaragua and India to prove their designs can be built in less economically developed countries. ATC’s work is life changing for both our designers, our student teams and our clients.

Target demographics:

low income and other under-served people

Direct beneficiaries per year:

150 students

Geographic areas served:

Central America and elsewhere around the world


natural building, solar power, and downloadable designs for affordable technologies that can make a positive difference in their lives, such as a solar vaccine refrigerator using no electricity or moving parts. Our largest program to date is "Mayan Power and Light," which trains young Guatemalan women in electricity, solar power, and carpentry so they can make a living and improve conditions in their communities.

ATC is a great organization! I’ve worked with them as a volunteer for over a year. The work they do is life-changing and fascinating.

As an engineer, I’ve been able to get involved with designing and optimizing solutions for poor people in developing countries – treadle pumps, clean stoves, solar vaccine refrigerators. Technology that makes a real difference to people’s lives AND allows some to create their own income-generating situation, a key opportunity to take them out of poverty.

As a volunteer, I’ve been able to travel to Guatemala and work on natural building projects to help communities at their schools and, in the future, a medical clinic. It’s been amazing to be able to make a concrete difference with my own hands and effort.

As a donor, I have seen the workings of the organization and feel confident giving money where so much of it is being used for its mission and not absorbed as too much overhead. Further, the designs that ATC develop are kept as open-source information so that the lessons learned in Guatemala can not only be spread to Africa, Asia, South America, etc., but can also be locally built and maintained, another key element in helping people by giving opportunity and employment rather than just charity. This principle allows ATC to make an even wider difference in the world.

I will continue to stay involved in this organization and to support them.

A few years ago I saw an inspiring presentation about the Appropriate Technology Collaborative (ATC) and how it was leveraging student brainpower in the US in collaboration with input from very low income people in Central America to design solutions that would improve lives while being truly affordable. But my real introduction to what that all means was on an 11-day trip to Guatemala in early 2012 to help on two ATC projects along with 16 other volunteers, including adults and university students.

The first project involved installing solar panels on the roof of a vocational high school on the north shore of Lake Atitlan to provide reliable backup electricity, since the grid power was rather unreliable. As a retired engineer I had a great time working with the other ATC volunteers and a couple local craftsmen (electrician and welder) to overcome interesting design obstacles and get the job done in our limited time. We also provided training materials so the school could start teaching classes in basic electricity and solar power.

The second project was at the other end of the technology spectrum: helping to preserve a traditional technology -- a building technique named "bajareque" taught to us by Mayan elders who still know how to build walls that are more earthquake resistant than adobe or even typical Guatemalan concrete, using bamboo, mud, stone, and twine made from dried local plants. We built a courtyard wall at an elementary school to help keep the young students from venturing off during recess. Besides helping with the construction, I created video documentation of the material preparations and the building technique.

The trip was incredibly fun and rewarding, not to mention being very well organized and managed by the ATC Director, John Barrie. As a result of that experience, I ended up joining the ATC board of directors, and as Treasurer I have moved us from spreadsheet accounting onto Quickbooks and filed our first 990EZ tax return, since our revenue increased across the $50K threshold in 2012.

If I had to make changes to this organization, I would...

Recruit more board members and volunteers to help the organization accomplish more of its inspiring and exciting mission.

Will you volunteer or donate to this organization beyond what is required of board members?
