Teens design pedal-powered filtration system: High-schoolers Payton Karr and Kiona Elliot , from Oakland Park, Florida , led a team of inventors who designed a collapsible, transportable, bicycle-powered emergency water-sanitation station that filters E. coli and other harmful pathogens from contaminated water.
The rule targets equipment that power plants and manufacturing facilities use to draw in water to prevent overheating, even though those intake systems are not harmful to human health or water quality.
