For years, Daniel Lacks has taken 杏吧视频 engineering students to African villages, showing them a different way of life and, more recently, aiding those they visited by installing solar panels in their villages.
What he and his students didn鈥檛 realize, though, was the inherent problem with that model.
Last summer, Lacks, chair of the Department of Chemical and Biomolecular Engineering, returned to the first village where he and his students installed solar panels in 2014鈥攐nly to find that the system hadn鈥檛 worked for months and the villagers didn鈥檛 know how to fix it. Though the solution ultimately was an easy one, he knew it could become a common problem.
鈥淚f you don鈥檛 know how to fix it, even though it鈥檚 very simple, it seems complicated,鈥 said Lacks, also the C. Benson Branch Professor of Chemical Engineering.
So when he took three students to Rwanda recently, they decided to flip the script. Instead of installing the panels themselves, they taught the villagers how to install them so they would know how to make basic fixes to the systems.
With an audience of villagers watching, students Kate Goldman, a senior civil engineering major; Dane Elliott, a junior chemical engineering major; and Alex Beisner, a senior chemical engineering, showed three young men how to use the tools, what parts were needed and how to put the systems together.
Lacks and the students donated two solar-panel systems: one for a woman whose sight is worsening and another for a young family with a baby on the way. With the solar panels, the villagers will be able to have light after dark, which before was only possible with candles and kerosene鈥攂oth dangerous options.
鈥淲hile there was a slight language barrier, the locals where extremely interested and engaged in learning about what we were doing, which made communicating with them that much easier,鈥 Goldman said.
But the villagers weren鈥檛 just learning鈥攖hey also contributed and provided innovative solutions when challenges popped up.
Because they couldn鈥檛 take many of the necessary tools on the plane, such as box and wire cutters, Lacks and his students had to obtain some of the necessities when they arrived in Rwanda.
Once they traveled to the remote village, though, they realized the wire cutters they purchased didn鈥檛 have a built-in crimping tool like the ones they used back home, which presented a problem when putting the system together.
Instead, a villager came up with a solution to work around the problem.
鈥淚 think they could see that something that looked intimidating at first really is something that they could easily do,鈥 Lacks said. 鈥淭hey鈥檙e not any less inclined to this. It鈥檚 just overcoming a barrier, which they were easily able to do.鈥
For Goldman, having the chance to show young girls that women are capable of becoming engineers was particularly rewarding. Of the three students who went on the trip, two were women.
The villagers weren鈥檛 the only ones to learn from the experience, though; the CWRU students took away many lessons as well.
鈥淥ne of the most important things that I learned was that it doesn't take a lot to make a difference in someone's life,鈥 Goldman said.
Lacks and his students hope now that the young men know how the panels work, they will be able to fix problems and, if desired, purchase the parts and install new ones on other homes.
Moving forward, Lacks plans to take this approach on future trips.
鈥淚t has more of an impact. It鈥檚 more enjoyable and there鈥檚 more interaction with the locals,鈥 he said. 鈥淭his is the way we want to do it.鈥
