Yi Wang ’09 received an MIT Public Service Center Grant to work in a D-Lab team on improving the efficiency of the charcoal and briquette production in Lunsar, Sierra Leone and other rural villages. After numerous trials, she found that coconut shells produced the most charcoal, however, several factors need to be improved for their charcoal production to become more efficient. Yi also participated in the ReachOut program, a literacy tutoring program that matches MIT students with children at a local after school center.
