Building a (one-stage) Anaerobic Digester

Kenya-based maker Babamzungu designed and built this proof of concept one-stage anaerobic digester to convert waste organic material into useful methane gas. Anarobic digesters work by placing organic material in an oxygen-free environment, where naturally occurring microorganisms digest the matter and turn it into methane and carbon dioxide. The gas can then be burned as a fuel. While this design isn’t the most efficient, the goal of his project is to create an affordable design that can be built using readily available parts. Looks great! [via afrigadget]
