BIOGAS FAMILY-PACK: BIOGAS STORAGE AND TRANSPORT UNIT FOR USAGE BY AN INDIVIDUAL OR FAMILY

摘要

Biogas is an alternative to other forms of cooking fuels currently being used in the rural households in India like firewood and dung cakes which emit smoke that not only pollutes the environment but is also hazardous to the health of the people who inhale it. However, it is not easily available to the people for two main reasons: firstly, compressing biogas and distributing it in cylinders fike those used for LPG has considerable difficulties and secondly, not every family can afford to have their own biogas plant because they, neither have enough cattle dung to feed the plant, nor do they generate enough organic waste to feed it. The objective of the present invention is to facilitate use of biogas as a replacement for traditional chulhas and to derive the best method to make it available to every rural family at affordable cost through design intervention. The invented product comprises an affordable, stable and easy to use gas balloon with an outer protective cover. It can be carried on the back like a bag pack and when not filled makes about a foot long roll. During use, the gas is pressurized by means of external weight that is made up of inexpensive resources which are easily available. A frame is provided to place the bag in which can also be made in-situ using materials available locally. Natural, biodegradable, renewable materials may be used everywhere possible, and where not, the materials used could be recyclable.
