Provo » A Utah engineer's idea to light up western Africa using kid power is going round and round.

Empower Playgrounds Inc. builds special merry-go-rounds that generate power for lights 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.

"If you want a peaceful Earth, you have got to get rid of the differences," EPI founder Ben Markham said. "You can't have some countries with high technology and other countries still not have light at night. Help the lower end catch up, and you're setting a foundation to change the world."

Markham says he got the idea while serving a mission for The Church of Jesus Christ of Latter-day Saints. He saw how dark it was in the concrete block schools and wondered how the children were expected to learn.

Markham, a retired engineer, worked with Brigham Young University students to develop a merry-go-round that could harness enough energy to power special lanterns. Students could use the lanterns to study at night, a huge development for villages located outside Ghana's spotty electrical grid.

EPI has also developed and installed an electricity-generating swing set, and a zip-line is in the works.

Markham said the first ideas for the merry-go-round generators were scratched on the backs of envelopes as he left his mission.

Near the equator, Ghana gets 12 hours of sunlight. A young student with daytime chores has no chance to study at night without an artificial light source.

"I sat in these buildings, saw how dark they were, and saw the lack of supplies," Markham said. "I'd shake my head and wonder how kids ever learned anything."

EPI provides the merry-go-rounds and lanterns for free. Once the equipment is installed, power is produced as the kids play on it.

The lanterns are powered by a specially modified camping lantern. Energizer developed the rechargeable lanterns for EPI, on its own dime, and the units can run for 35 hours at full power before needing to be recharged.

EPI continues to focus on Ghana, which EPI executive director Sarah Hall said is a safe place politically.

"I don't see (EPI) expanding any time soon, but I hope that it will expand eventually," she said. "There are so many schools in Ghana, it would waste a lot of resources to try and move it somewhere else anytime soon."
