Takamoto Biogas is:
...building biogas systems for small farm owners. The biogas is mainly used for cooking and lighting, though it can also be used for heating, driving chaff cutters, water pumps and electric generators. With the cost of firewood, kerosene and petrol increasing, the cost of these systems can be paid back in one to two years, depending on the local cost of energy, while the systems will last for 30 years on average.
