2. We feel that by working towards improving the communities energy situation, we can alleviate or even mitigate the problems seen in the communities infrastructure as a whole. Our chosen design area - Energy

3. Energy Sources Considered Wind Geothermal Hydroelectric Solar

4. Our chosen source - Biogas  Mixture of gases produced during the anaerobic decomposition of organic matter.  Can be compressed and used for various purposes or transformed  Fuel can be sourced from food by- products and animal/(human?) waste

5. Reasons for choosing Biogas Slurry is high in vitamins and an effective fertiliser Slurry allows crops to grow healthier Helps local industry Saves the effort of collecting and carrying of firewood

7. Person puts in rubbish/waste Start Rubbish/waste breaks down, releasing methane and turning into slurry The gas takes the path of least resistance and diffuses into the adjoining barrel The slurry can be emptied out of the barrel and used as fertiliser The gas can be burned to produce steam which would turn turbines and produce electricity The gas can be used to produce fire which can be used to cook and clean End Small Scale Process Diagram
