Introduction
Product ecologies illustrate how the different tools of the GVCS work together. For example, motors, power units, and implements interchange within the tractor, microtractor, car, truck, fabrication, and bulldozer infrastructures. Ecologies can also refer to the way in which a set of tools can be put together to produce a wide array of products - such as the induction furnace contributing to the production of tractor parts, construction roofing, or wire.
Note also: the materials ecology shown on this page should be compared to and integrated with the Solar Economy flow graphic here
Product Ecologies
