Growing algae on sewage could generate affordable biofuels. To make this work you begin with a series of small artificial rivers where waste water flows and algae is cultured. In those ponds is a paddle wheel, which pushes the water about and mixes algae into the waste water. The shallowness of the rivers encourages sunlight and helps the algae grow.
