（24-25高二下·云南昆明·阶段练习）When young James completed his chores after school, he would light a kerosene (煤油) lamp to read his books. There was no electricity in James’s hometown, a region in Tanzania, so his family was forced to burn expensive oil for him to learn after dark. Many families in Tanzania rely on kerosene lamps to provide light after dark. These lamps produce dim light and are expensive to fill. They also carry the risk of burns. Parents often send their children to bed, rather than allowing them to use the lamp to read.
But now, James’s company, Soma Bags, is providing a solution, which was inspired by a professor who carried around a solar charger for his phone, sewn (缝制) into a fabric bag. “It gave me the confidence that what I want is going to work,” said James. He started in 2016 by hand-making 80 backpacks per month, sewing a solar panel sourced from China onto each one. The panel was charged during the children’s walk to and from school. By the time they returned home, they would have enough power for a reading light.
A fully charged bag can power a light for 6 to 8 hours, meaning that one day of bright weather can allow for multiple nights of reading, even if cloudy weather arrives. The backpacks are more affordable than using an oil lamp. A solar bag costs between 12,000 and 22,500 Tanzanian shillings, with the reading light included at the same price as 12-22.5 days of using a kerosene lamp. Made from recycled cement bags found on the streets, the backpack material is durable, lightweight, zero waste, and comes at no cost. The backpacks look good, too; in the middle of the bags, the white pattern of a giraffe appears within bright yellow or green stripes.
“It’s innovative,” said Joseph Manirakiza of the UN Development Programme, which has supported Soma Bags since 2023. “I never thought someone would think of turning waste cement bags into something useful.” Soma Bags has been recognized by numerous awards and institutions, including the UNDP and the British government.
