A group of South African entrepreneurs are taking plastic bags and refashioning them into solar powered backpacks designed to give children light to study with.
The plastic bags are cleaned and turned into a textile-like material. They then sew the material into backpacks, and add a small, removable solar charger, which collects power as the kids walk home.
The chargers can be easily removed and screwed onto lamps made from mason jars. They then provide six to nine hours of light, crucial for studying if the kids are among the 1.3 billion people worldwide without regular access to electricity.
