A multi-function, field-deployable resource harnessing apparatus having, in its embodiments, an inflatable reflector apparatus comprising at least one manufactured parabolic mirror made from a pressure-deformable reflective covering of an inflatable ring for focusing electromagnetic energy from radio frequency radiation (RF) through the ultraviolet (UV) radiation including solar energy. A first main embodiment of the inflatable reflector apparatus generally utilizes two pressure-deformable membranes, at least one of which is reflective. A second main embodiment utilizes a reflective membrane and a transparent membrane. In addition to the reflector apparatus, the modular apparatus typically further includes modular assemblies to increase versatility facilitate use, and/or enhance safety such as, for example, a modular support and orienting assembly, a separate support ring, a safety shield or cage, a focal point support assembly, a safety cover, a safety net or mesh, and a stabilizing assembly. Portability is enhanced by complete collapsing of the inflatable device.
