Methane Digesters For Fuel Gas and Fertilizer, With Complete Instructions For Two Working Models -- by L. John Fry, Santa Barbara, Calif. 93103, © 1973, Eighth Printing (out of print). Excellent manual on making and using methane -- biogas. Fry developed his techniques while running a pig farm in South Africa, designing the first full scale displacement methane plant. Good information on integrating biogas production with gardening and farming, and with pond-culture food production. Designs for a Sump Digester using 55-gal oil drums and an Inner Tube Digester. With thanks to Kirk McLoren.

Nepal Biogas Plant -- Construction Manual. Construction Manual for GGC 2047 Model Biogas Plant. With Dutch and German support, Nepal's Biogas Support Programme has built 95,400 biogas plants in 10 years, with potential for half a million more. These are fixed dome biogas plants, designed in Nepal. Sizes are household-scale from 4 to 20 cubic metres. The feedstock is cattle dung and water (but other feedstocks will work just as well). For instance, the 4-cubic-metre plant requires input from 2-3 cattle, the 10-cubic-metre plant needs 6-9 cattle. This manual includes full construction details, plans and data. With thanks to Olivier Morf.
Jean Pain: France's King of Green Gold -- In the 1980s Frenchman Jean Pain built a home-made power plant that he claimed supplied 100% of his energy needs. The core of the system was a 50-ton compost mound, three metres high and six across, made of pulverized tree limbs and underbrush. Buried inside the compost was a 4-cubic-metre sealed steel tank 3/4-full of the same compost, producing methane -- bio-gas. Tubes connected the tank to a pile of 24 truck-tyre inner tubes, the gas reservoir. Pain said he used the gas to cook all the food, fuel a truck and produce electricity, via a methane-fuelled internal combustion engine that turned a generator. The truck ran off two gas bottles on the roof. Another tube ran from a well and into the heap, with 200 metres of tubing wound round the tank; Pain said the water emerged at 60 deg C at 4 litres a minute, which was enough for central heating, and for the bathroom and the kitchen. The compost heap continued fermenting for nearly 18 months, and then yielded 50 tons of natural fertilizer. (With thanks to Ramjee Swaminathan.)
