Growing algae in sewage to create biofuels

A channel in which algae is bred and gently stirred with a paddlewheel.

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. And that algae is pretty important, because it’s what gets turned into biofuel.

Now You See Them, Soon You Won’t
The controversial new method is said to be less expensive and more environmentally friendly than running highly polluting crematoria or using up valuable land for graves. The departed would go into the sewage systems of towns and cities and then be recycled in water processing plants.

The proposals are being studied by the EU and if approved, it would mean the procedure could be used across Europe. However, opponents of the plans say it smacks of a Frankenstein callousness towards the dead and one survey in Belgium found many people found the idea “disturbing.”

Drinking Water, Straight from the Toilet

 Rich people sewage always sells for more than the sewage of the poor

A growing number of cities and counties in the US grappling with water shortages are turning to a solution that may be tough for some homeowners to stomach: purifying sewage water so that residents can drink it.

Los Angeles mayor Antonio R Villaraigosa announced a proposal on Thursday to begin using heavily cleansed sewage water to increase drinking water supplies. The move comes as California braces for the possibility of the most severe water shortages in decades.
