The performance of such wet biomass (animal waste) systems is outlined in Agriculture and Autonomous Power Supply, EOLSS on-line, 2002, and summarized in Table 3. Autonomous power supply must also include human and animal power (as discussed in Human and Animal Powered Machinery, EOLSS on-line, 2002) which, although of great relevance to small farms in the poorest regions, is otherwise declining in relative importance.
Milling rice for home consumption can also be done over a long period, and in Asia it is common for a mill owner to 'rent' his machine to customers. Rental markets for land preparation, with the use of animals or tractors, were once common in the United States, when plows were scarce, and in Europe. Such rental markets are now common in Asia wherever tractors or power tillers have penetrated.
