Nordica MacCarty, a faculty member in the Humanitarian Engineering Program at Oregon State, talks about improving the lives of women and children in the developing world through cleaner-burning cook stove technology. We also follow the unlikely journey taken by assistant professor Chinweike Eseonu, three women from the tiny town of Monroe, Oregon, Spanish instructor Loren Chavarria, and three determined engineering students, all made possible by some tasty Mexican food.
