After witnessing constant blackouts in India while on annual vacations with her family, Maanasa Mendu became determined to create a new, affordable device that could harness renewable energy. “For over one fifth of the global population, darkness remains a permanent reality,” says the Ohio native. “Electricity is a fundamental of modern society, and providing a sustainable source of electricity to our entire world should be a top priority.” Called Harvest, Maanasa’s invention won her the top prize at the 2016 Discovery Education 3M Young Scientist Challenge, which earned her the title of America’s Top Young Scientist. “Basically, I created an energy-harvesting device inspired by leaves,” Maanasa explains. “Whenever this ‘leaf’ is bent due to the impact of wind or precipitation, or whenever it’s exposed to sunlight, it produces an electrical charge.” The kicker? It costs only about $5 to produce. Aiming to partner with a nonprofit to eventually prepare the device for commercial distribution, Maanasa says her goal is to “deploy Harvest to transform at least one life through light.” What a bright idea! ?: @kate_sweeney #21under21
