제 1장 기술혁신의 개요
Ⅰ. 기술혁신의 정의
1. 기술변화에 대한 경제학적 관점
1) 고전주의 경제에서의 기술혁신 파악(아담 스미스, 마르크스)
고전경제학자들 중에서도 기술혁신이 경제적 진보를 가져온다는 논의를 전개한 사람들이 많다. 아담 스미스는 분업은 작업자들의 전문화된 발명을 유도
II. How is CBM formed
Coalbed methane (CH4) forms in one of two ways. During the earliest stage of coalification (the process that turns plant detritus into coal), biogenic methane is generated as a by-product of bacterial respiration. Aerobic bacteria (those that use oxygen in respiration) first metabolize any free oxygen left in the plant remains and the surrounding sediments. In fresh water
Digestion tank production gas is a biogas produced by artificial anaerobic digestion of organic wastes with bacteria in the digestion tank. This can be divided into mergence gas which produce bio-gas by putting more than two of them together, among the organic waste gas, waste water gas, livestock· sewage gas, sewage sludge gas, depending on the type of organic waste. Because they are artificial
Ⅲ. Theoretical analysis of the waste problems
We can approach to the analysis of problems to be solved at both a micro and macro level. What we will deal with is the environmental problems taking place all over China, which are characterized by a mix of pervasive influences and a number of factors. It follows that it is more appropriate to take a macro approach which enables us to see problems
Pros- Unlike regular fuel cell, MBFC can make energy in very mild condition.- MBFC can produce energy by consume variety organics.
Cons- MBFC need electrochemical mediator this mediator generally not degradable and very poisonous. so mediator can make 2nd pollution.- Output is low and unstable compared to general fuel cell.
The need for MBFC
