TVA - TVA scientists test strobe lights on fish - Scientists installed underwater strobe lights at a Tennessee Valley Authority power plant in order to keep fish away from the pipes that draw water for the plant, so that fewer fish are killed, which improves efficiency and helps meet tougher Clean Water Act standards. If it works, this project will expand to other plants.
This project seems to be beneficial, to water cleanliness, fish safety, and plant maintanence. If the lights do not have any deteriorating effects, they quite possible have future implementations, provided that they are cost-efficient.
