Daniel Sheridan, a 23-year-old student at the University of Coventry in the UK, has recently created a simple seesaw device that converts the energy generated by children on the top and bottom of the seesaw to the electrical storage device through cables buried in the ground. The output current is sufficient to provide illumination for a classroom.
In Africa, many schools are open to older students at night, but classroom lighting can only rely on burning candles or kerosene lamps. Sheridan calculated that playing on the seesaw for 5 to 10 minutes would generate enough electricity to provide a classroom full night.
Sheridan plans to leave for a village near Jinja, Uganda, using local materials to test and perfect his prototype. “I hope that in the end I will be able to design a complete playground made up of different devices, and the electricity generated will meet the needs of the entire village.â€
