GRAND RAPIDS, Mich. (AP) — Two brothers who also are Grand Rapids natives are back in the state this week to talk about their African adventure.

Whit Alexander launched a business in Ghana that focused on renting high-quality rechargeable batteries to power lanterns, radios and battery-powered cellphone chargers. The idea was to save Ghanaians (guh-NAY'-uhnz) money and help protect their environment.

Journalist Max Alexander wrote a book about his brother's efforts.

"Bright Lights, No City: An African Adventure on Bad Roads with a Brother and a Very Weird Business Plan" came out earlier this summer.

Both men are to be in Grand Rapids on Wednesday at the Fountain Street Church and at a district library in Ann Arbor on Thursday.
