Plant Waste Turned Into Energy

In this world where going green is the in thing, how about this method that involves getting power from waste parts of the cassava plant? You might be more familiar with tapioca as the common name though, and thanks to the efforts of Nigerian engineer Dr. Joseph Adelegan, this devised method collects cassava waste which in turn is transformed into a biogas that generates electricity as they turn small turbines. The electricity produced will be enough for basic needs such as lighting and low-powered electronics, although heavy duty usage like your Xbox 360 and refrigerator will still require the services of a grid.
