Backpacks Create Their Own Light

Inventor Innocent James created backpacks that use solar panels to make their own study lights.

Soma Bags have solar panels that capture enough sunlight to power a nighttime reading light.

When Innocent James was in college, he bought a mobile library cart and began lending books to school-age children in Tanzania, where he lives. He was bothered when he realized that kids were returning the books without having read them because their homes were too dark at night. So James came up with a solution: a solar-powered backpack that can provide the light students need to read and study.

James knew why kids needed more light because he had faced the same problem as a kid. Less than half of Tanzania’s population has access to electricity. Families light their homes with oil-burning kerosene lamps. But the oil is expensive, and many people cannot afford to have their homes lit all evening.

In 2016, James began turning old cement bags into backpacks with attached solar panels and reading lights. James designed the bags for students. During a walk to and from school, the panels collect the Sun’s energy, which can be used to power a reading lamp at night so that kids can spend more time reading or doing homework. A cloudy day is no problem. One panel holds enough power for six to eight hours of light, so it can be used for two or more evenings before it requires more sunlight.

What started with 80 backpacks per month turned into thousands after James started a company called Soma Bags (which means “reading bags” in Swahili) to manufacture them. James still uses old cement bags, which come at no cost to the company. Because of this, James says, it’s cheaper to buy one of his backpacks than to use a kerosene lamp. The company also makes bigger bags that can power other devices like phone chargers.

The Soma Bags factory in Bulale, Tanzania, employs 65 people.

Currently, customers are demanding 13,000 backpacks per month, more than what the company is able to make. But more and more kids now have the backpacks, which means that digging into homework—or just a good book—at night is no longer a problem.

Did You Know?

About 11 percent of the world’s population does not have access to reliable electricity.

Long-Overdue Recognition

Edmond Dédé

You may know about classical composers Mozart and Beethoven, but have you ever heard of Dédé? As a Black American composer, Edmond Dédé struggled to have his work taken seriously, which may be why many people don’t know his name. Now, more than 100 years after his death, Dédé is getting some long-deserved recognition. 

In February, an opera by Dédé had its premiere performance in his hometown of New Orleans, Louisiana. An opera is a story set to music and performed by singers and instrumentalists. Dédé’s opera, called Morgiane, is about a young woman who is kidnapped and her mother’s efforts to rescue her.

Born in 1827 to free Black parents, Dédé grew up in New Orleans. Today the city is known as the birthplace of jazz music. But when Dédé was growing up, it was a center of classical music. Dédé took music lessons from his father and others and became an acclaimed violin and clarinet player. But racism kept Dédé from earning much respect as a composer. Eventually, he moved to Europe, where he wrote music until his death in 1901.

Dédé finished Morgiane in 1887, but his handwritten opera was lost for more than 100 years—until it turned up in a collection of music being stored at Harvard University. In 2025, Morgiane is finally being heard. After premiering in New Orleans, the opera was performed in New York City and Washington, D.C.

Patrick Dupre Quigley, who conducted the New Orleans performance, once called Morgiane “the most important opera never heard.” Quigley says many people don’t realize how many Black Americans have composed classical music because their work wasn’t always as highly appreciated as that of white composers.

“There is this story that we have told that people of color are only now becoming part of the timeline of classical music,” Quigley told CNN. “And the reality is that in the United States…Black people were [already] participating in classical music.”

Homes, office buildings, and even cars and backpacks can be powered by the energy of the Sun. How does solar energy work, and how else can we harness it?
