"The scrubber at Harbor Point is the same one used two years ago at Peach Bottom nuclear power plant on the Susquehanna, where it was estimated it removed 640 pounds of nitrogen and 90 pounds of phosphorus from the water. The device processed heated water discharged from the Pennsylania power plant, inspiring Kangas to suggest that larger algae scrubbers might effectively augment or even replace the cooling towers nuclear plants now use to treat the water with which they cool their reactors."

very cool!
