Afrigadget reports on a project to develop playground equipment that generates electricity "that can be used to power school classrooms in Africa."

As BBC quotes him,

"The current need for electricity in sub-Saharan Africa is staggering. Without power development is extremely difficult. The potential for this product is huge and the design could be of benefit to numerous communities in Africa and beyond."

Afrigadget adds,
The idea came about after travels to East Africa, where he taught at a school and was inspired by the students. Daniel developed the see-saw power design as part of his final year at Coventry University. He has calculated that five to 10 minutes use on the see-saw could generate enough electricity to light a classroom for an evening.
