Derived Resources
We can think of resources in terms of their availability:
- Ready-to-use resources are resources that exist in a visible, recognizable state –
in other words, they can be used "as is."
- Derived resources are "hidden" and become available only after undergoing a
transformation of some kind.
Resources are transformed through the Operators and application of one or more
inventive fields:
Mechanical, Thermal, Chemical, Electrical, Magnetic and Electro-Magnetic
(MeThChEM).

The nature of a resource is such that there are "natural" ways to exploit it -
i.e., different types of resources are associated with one or more types of effect. The diagram
below illustrates the relationship between resources and effects. Of course, some overlap always
exists in a system. Thus, all effects are usually available simultaneously.
