Physical Sources

Physical Sources are the rivalrous, material aspects of reality such as space, time, mass and energy required to host (store and express) any design.

Physical Sources are the tangible Means of Production such as Land, Water, SUN, Tractor, roto-tiller, drill press, etc.

Physical Sources are sometimes 'Instances' of Virtual Sources. For example, the design of an Earth Block Compressor is a Virtual Source, but the land, buildings, tools, steel, plastic, grease, energy, space needed to construct each working copy are the Physical Sources.
