Smith wanted to design a locally producible fuel that would eliminate Haitian preference for wood-based fires. Haiti, the poorest country in the Western hemisphere, is 97% deforested but families continue to rely on wood fires in the home for cooking. Smith saw that these families would eventually have to buy imported fuels, which would likely be unaffordable. In addition, wood-burning produces smoke inhalation in the home, which Smith discovered is the #1 cause of death among children under five years old in the developing world.
She reveals that the first version of locally producible charcoal briquettes did not actually burn, nor were they produced from locally available materials!
When you compare her 2006 TED talk to the 2004 DIY charcoal production manual, it’s clear that Smith has also learned to change how she presents the problem she solves. Rather than focus on the environmental issue (deforestation), which local families don’t have the luxury to consider, she opens her talk with the impact on childhood mortality – a much more compelling reason to switch to her fuel.
This is a great example of design-for-DIY: rather than create an invention that you intend to manufacture then sell to the developing world, create a way to teach the local communities to make and possibly sell the solution themselves. Design-for-DIY solves two needs: the original problem, and the economic challenge. Smith’s instruction manual is written such that anybody with access to agricultural waste and an empty oil drum can become an entrepreneur, producing and selling home-safe charcoal to the local community.
Imagine how powerful this could be if someone from the MIT Sloan School of Management teamed up with her?
