If you heard that underwater strobe lights were being installed somewhere in Alabama, you might think it was for some new high-tech kind of disco. But actually, these strobe lights are being placed near the intake pipes of a coal-fired power plant, and are being tested as a new way to save fish from being trapped and killed. According to the Environmental News Network, the strobes flash 300 times per minute, and create a wall of light that deters fish from entering the pipes. This novel idea may prove especially helpful to some 500 power plants that will soon have to meet strict new EPA requirements on the issue – and as for the fish, well, this certainly gives new meaning to that old disco classic “Stayin’ Alive.”
