Amy Smith and the low-tech solution

Have you seen the great work of Amy Smith? She operates D-lab nestled beneath the infinite corridor at MIT.

Fumes from indoor cooking fires kill more than 2 million children a year in the developing world. MIT engineer Amy Smith details an exciting but simple solution: a tool for turning farm waste into clean-burning charcoal.

Amy and her students are creating low-tech technologies to benefit people who have little access to the systems many of us expect.

Happy Ada Day!
