Eastern Regional High School
Ultraviolet water filtration and storage device
The Eastern Regional High School InvenTeam invented the Maji Drum, which brings together filters, ultraviolet lights, and a bicycle to provide communities with potable water and storage at a cost of about $100 per 1000 units. Using an adaptable mount with a high voltage motor attached to a flywheel, users can generate a consistent source of energy with the ergonomic custom bicycle mount system. The system pre-filters the water, exposes
it to ultraviolet light, and stores it inside the drum at a rate of 4 L per min.
