Engineering Brightness: Building A Global Network of Social Entrepreneurs builds on a successful local initiative that has the dual foci of designing, building and distributing personal lights for those without and impacting light poverty. Students in K12 have been collaborating to design and build and solar charged lanterns which have been distributed to several countries. Engineering Brightness now has relationships with schools in Guatemala. The hoped-for outcome is an active network which will become a learning laboratory, facilitating collaboration and replication. UNESCO estimates that 1.3 billion people live without safe, reliable light after dark. (International Day of Light, 2018).
