The organization is making merry-go-rounds that have a clean tech twist — onboard kinetic energy harvesters that store that energy in batteries for later use.

This idea is similar to the Soccket soccer ball by Uncharted Play that creates and stores electricity from being kicked around and played with. The stored electricity can then be used later for lighting, etc.

At schools in Ghana where Empower has provided equipment, kids split into lantern groups and study together at night where before they couldn’t study past sunset. The lanterns last 50 hours on each charge.
