Generating electricity is child's play in Ghana
None
A Utah engineer's project to convert the energy of children's play into electricity to light up schools continues to expand in the West African nation of Ghana. Empower Playgrounds, Inc., builds special merry-go-rounds that generate power for lights in schools in villages where electricity is scarce or not found at all.
The nonprofit started three years ago with one playground generator in Ghana. Now 10 merry-go-rounds have been installed and EPI has plans for 25 more in 2010. (AP)
