The Sunflower Seed Huller and Oil Press -- by Jeff Cox (from Organic Gardening, April 1979, Rodale Press): Vegetable oils used to be one of those items you just HAD to buy. Now here's how to make your own. In 2,500 square feet, a family of four can grow each year enough sunflower seed to produce three gallons of homemade vegetable oil suitable for salads or cooking and 20 pounds of nutritious, dehulled seed -- with enough broken seeds left over to feed a winter's worth of birds.

Fuel From Sawdust -- by Mike Brown (from Acres, USA, 19 June 1983): Conversion of cellulose, such as sawdust, cornstalks, newspaper and other substances, to alcohol -- "a fairly uncomplicated and straightforward process". This is the old way -- it works, but it's not efficient and not economical.

The UC Davis biodiesel study -- "Chemical and Bioassay Analyses of Diesel and Biodiesel Particulate Matter: Pilot Study -- Final Report" by Norman Y. Kado, Robert A. Okamoto and Paul A. Kuzmicky, Department of Environmental Toxicology, University of California, Davis, California, November 1996. This U.S. Department of Energy study found that the use of pure biodiesel instead of petroleum-based diesel fuel could offer a 93.6% reduction in cancer risks from exhaust emissions exposure.

Emissions are categorized and compared with petroleum diesel fuel in different types of diesel engines. Section 2 on Engine Testing Procedures and section 3, "Environmental Effects of the Main Exhaust Gas Components", are well worth a read in their own right.

SVO emissions bibliography -- Compiled by Wolfgang Rougle from the 55-page bibliography of the Iowa State biodiesel course. This larger bibliography covers all research aspects of biodiesel and some non-emissions aspects of SVO, and may be useful to you. It can be found at:
http://www.me.iastate.edu/biodiesel/Bibliography/bibliography.html

The modelling of the biodiesel reaction -- As part of their work to design a continuous reactor for the production of palm-oil methyl ester, Michael Allen and Gumpon Prateepchaikul at the Energy Group in the Department of Mechanical Engineering at Prince of Songkla University in Thailand produced a spreadsheet modelling the complex series of reversible reactions which take place during the biodiesel production process. "Applying this model made possible several recommendations to enhance palm-oil methyl ester production in batch reactors..." You can use the spreadsheet to change one parameter in the process and see how it affects the others. Full-text document here (html).

The Fats and Oils: a General View, by Carl L. Alsberg and Alonzo E. Taylor, 1928, Food Research Institute, Stanford University, California
First in a series of five Fats and Oils Studies published in the 1920s by the Food Research Institute. World War 1 had demonstrated the basic importance of the fats and oils for food, feed, and raw material for industry. These publications sought to address a lack of reliable data on which to base policy and business decisions. Good overview of the subject written in layman's terms, covers nature and sources of fats and oils, properties, technology, production, international trade and more. Not that much has changed since then, it's just grown more complex. A clear and informative guide -- useful information for anyone making biodiesel, also much of interest on how agricultural production and the trade in commodities can influence prices and availability of feedstock. Also much of interest for soapmakers. Full text online. More resources -- See Fats and oils

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.

Put a chicken in your tank -- Eccentric British inventor Harold Bate found a way of converting chicken droppings to biogas and running his car on it. He claimed chicken power would run a car faster, cleaner, and better than gasoline. Bate said he'd driven his 1953 Hillman at speeds up to 75 mph without the use of gasoline.

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.)

Wood-Ethanol Report: Technology Review, Environment Canada 1999 -- good overview of the problem of producing ethanol from cellulose and the current solutions on offer.

The Fuel Injection Equipment (FIE) Manufacturers (Delphi, Stanadyne, Denso, Bosch) issued a statement on biodiesel. They strongly support it, but they have their concerns too, and they're very involved in standards development. They had a fright in Europe in the early 90s when the introduction of low-sulfur diesel saw widespread damage to injection systems, with excessive wear and failure. The same thing happened in California. They don't want it to happen with biodiesel. This is their statement.

Biodiesel quality testing: Scientists at USDA's Agricultural Research Service have adapted a sophisticated tool known as near-infrared spectroscopy -- NIR -- to help speed the development of biodiesel fuels made with vegetable oils. The standard for measuring biodiesel quality has been a complex analytical method called gas chromatography (GC). But GC is a complex piece of laboratory equipment, requiring technical expertise and at least an hour to perform. It also requires chemical reagents and solvents that need special handling and costly disposal. NIR is a safer and faster way to check the quality of biodiesel fuel, and no special training is needed.

Liquefaction -- Chapter 3, Energy Applications of Biomass, Michael Z. Lowenstein (Ed). (Elsevier Applied Science Publishers, 1985). Natural processes that produce liquids suitable as fuels are performed by certain tree species (e.g., the Brazilian Copaifera langsdorfii tree that yields sesquiterpenes that can be used as diesel fuels without modification, and plants that bear oil seeds; e.g., sunflowers). An approach to the natural production of liquid fuels by biomass is under investigation by Nobel prize winner Melvin Calvin using a combination of natural photosynthesis and genetic manipulation. The overall process consists of three steps: hybridization of Euphorbia lathyris with E. esula,which produces fewer hydrocarbons than E. lathyris but grows as a perennial rather than an annual; modification of the photosynthetic pathway of the hybrid to cyclize C 15 intermediates so that sesquiterpenes are formed; and transfer of the gene that codes for sesquiterpene production from C. langsdorfii to the plant.
