A Novel Design for a Biogas Generator in Developing Countries by Joanna Read A thesis submitted in partial fulfillment of the requirements for the degree of BACHELOR OF MECHANICAL ENGINEERING The proposed generator is designed to produce 3.2 cubic meters of biogas per day. This is the amount of biogas necessary for the daily cooking requirements an average family of eight people, the norm in Pabal. Initial conceptual designs are outlined and analysed by the use of a design matrix. The final design is also analysed and suggestions made for further improvements.

"Open-source governance is a political philosophy which advocates the application of the philosophies of the open source and open content movements to democratic principles in order to enable any interested citizen to add to the creation of policy, as with a wiki document. Legislation is democratically opened to the general citizenry, employing their collective wisdom to benefit to the decision-making process and improve democracy.[1]"

"Consensus decision-making is a group decision making process that seeks the consent, not necessarily the agreement of participants and the resolution of objections. Consensus is defined by Merriam-Webster as, first, general agreement, and second, group solidarity of belief or sentiment. It has its origin in the Latin word cōnsēnsus (agreement), which is from cōnsentiō meaning literally feel together."

"Meritocracy, in the first, most administrative sense, is a system of government or other administration (such as business administration) wherein appointments and responsibilities are objectively assigned to individuals based upon their "merits", namely intelligence, credentials, and education,[1] determined through evaluations or examinations. The "most common definition of meritocracy conceptualizes merit in terms of tested competency and ability, and most likely as measured by IQ or standardized achievement tests."[2] Supporters of meritocracies do not necessarily agree on the nature of "merit", however they tend to agree that "merit" itself should be a primary consideration during evaluation. In a more general sense, meritocracy can refer to any form of government based on achievement. Like "utilitarian" and "pragmatic", the word "meritocratic" has also developed a broader definition, and can be used to refer to any government run by "a ruling or influential class of educated or able people.""
