The article describes how floating 'eco-machines' generating their own power and containing "treatment cells" supporting diverse life forms could rehabilitate heavily polluted ponds and canals, allowing them to once again sustain healthy population of plants and animals. 'Eco-machines' replicate the natural processes in an aquatic environment, but in a more concentrated and effective form.
Successful examples include waste treatment ponds handling contamination from landfill and poultry production, a sewage-laden canal, and a brackish, algae-loaded pond in a golf course. Future applications include fish culture and harbor-front restoration.
