Hydroelectric power is the oldest large-scale system for generating electricity, dating back more than one hundred years. Hydroelectric power is considered “clean” because it doesn’t emit carbon or other pollutants. But no technology is entirely clean; large-scale hydroelectric plants are usually created by damming a river, which drastically alters the local ecosystem and affects the water rights of those downstream. A joint project between researchers at New Mexico State University and Ho Chi Minh University of Technology is proposing small hydroelectric power plants that don’t rely on dams, but instead use existing natural or man-made water flows.
