Positioning this technology in the
Functionality Grid
Reformatted from: Van Wyk, Rias J: Technology - A Unifying Code, 2004, SMG, Cape Town, p.34. Based on: Ropohl, Gunter: Eine Systemtheorie der Technik, 1979, Carl Hanser Verlag, Munich and Vienna, p.178.
This Newsbrief focuses on bio-fuels, such as corn ethanol, cane ethanol, bio-diesel and cellulosic ethanol. More particularly it focuses on the fossil fuels required to create these bio-fuels. In terms of the Atlas of Technological Megatrends it is concerned with the functionality of energy processing.
The recent emphasis on green technologies has caused a re-awakening of interest in bio-fuels. This Newsbrief looks at the technological potency of the bio-fuels mentioned. Technological potency refers to the relative level of technological performance. It is measured by means of technology performance metrics (TPMs). In the case of bio-fuels two TPMs are used:
  • Energy output relative to one unit of fossil-fuel input
  • Emission intensity relative to comparable fossil-fuel emissions
*Comparable fossil fuel emission for bio-diesel is diesel. For other bio-fuels it is gasoline. Bourne, Joel K. "Green dreams" National Geographic, October 2007, Vol. 212, No. 4, pp. 41-59
Note the large differences in TPMs. These indicate possible technological and environmental superiority of cellulosic ethanol compared to other bio-fuels.
