TLDR
An inflatable, multifunction, multipurpose, parabolic reflector apparatus having a plurality of manufactured parabolic mirrors made from a pressure-deformable reflective covering of an inflatable ring is described in this paper.
Abstract: 
An inflatable, multifunction, multipurpose, parabolic reflector apparatus having a plurality of manufactured parabolic mirrors (14, 16) made from a pressure-deformable reflective covering of an inflatable ring (12) for focusing electromagnetic energy from radio frequency radiation (RF) through the ultraviolet radiation (UV) and solar energy for (1) heating and cooking, for (2) electrical power generation, for (3) enhancing the transmission and reception of radio signals, for (4) enhancing vision in low-light environments, and for (5) projection optical signals or images. The device also has non-electromagnetic uses, such as the collection of water. A first main embodiment utilizes two reflective membranes.(14, 16) A second main embodiment utilizes a reflective membrane and a transparent membrane. Portability is enhanced by complete collapsing of the inflatable device.
