Cleantech in the Developing World
Last night I attended a panel titled “Clean Technology - Sustainable Growth: Innovating and Implementing in the Developing World.” The panel was at Santa Clara University and sponsored by the California Clean Tech Open and the university’s Engineers Without Borders student chapter. Outside the theater there were some displays set up showcasing some of the SCU Engineers Without Borders projects, including the low pressure solar distillation apparatus pictured on the right. Other displays showed low cost building insulation derived from denim and pictures from previous projects.
The main assembly began with a presentation by an SCU-EWB co-chair, Yasemin Kimyacioglu, about the low pressure solar distillation project. The apparatus uses an array of solar tubes and coper pipe to pre-heat the water. An electric powered vacuum allows the water in the pressure cooker to boil at 57 degrees Celcius, rather than the normal 100 degrees. The purified steam runs through a condensing coil which utilizes the original contaminated water as a coolant. The prototype is nearly complete and testing will begin soon. There are still some technical hurdles to overcome before deployment, such as elimination of the contaminants from the pressure chamber.
The panel began immediately following the SCU EWB presentation. It was moderated by R. David Hague, VP of Business Development at GreenMountain Engineering, a consulting firm focused on renewable energy and clean technology. The panel included:
- Patrick Freeburger - Co-founder of BuildFast, winner of the CCTO 2007 prize for Green Building
- Rebeca Hwang - Co-VP BASES Social E-Challenge and Judging Chair for CCTO
- Dr. Ashok Gadgil - Senior Staff Scientist at Lawrence Berkeley National Laboratory
- John Rockwell - Managing Director, Element Partners, a clean technology investment firm
The bulk of the panel session centered around the problems with deploying clean technologies in the developing world. One of the main problems is a difference in values. Each panelist had a personal anecdote illustrating the common misunderstanding of the problems people in the developing world face. For example, Ms. Hwang described a project to deploy water filters in Nicaragua only to find the local men would rather spend their money on beer. Dr. Gadgil told of an unsuccessful attempt to utilize cheap, single family open space housing plans in Afghanistan, where extended families live together with separate areas for the men and women.
Mr. Rockwell pointed out that the only way to be successful in the developing world is to figure out how to make money. Mr. Freeburger described how his company, BuildFast, changed their business model from building complete housing solutions to providing key materials and knowledge to local builders. Dr. Gadgil pointed to SELCO in India as a good example of meeting the needs of the local people. They provide renewable energy solutions to Indian homes and businesses which could not normally afford them. They are able to replace kerosene lighting with CFLs powered by batteries charged by solar arrays. The service provides pre-charged batteries and the lighting solution delivered where needed replacing kerosene with a clean, more affordable, better lighting solution.
Understanding the culture, the value and needs are more important in many ways than the technology. You can be the foremost authority on water decontamination, but unless you really understand the local situation, your solution will probably not be successful. You are simply adding to the junkyard of Western technologies in the third world, as Dr. Gadgil called it. Sometimes you need to learn before you can teach.
