Multi-function field-deployable resource harnessing apparatus and methods of manufacture

A multi-function, field-deployable resource harnessing apparatus 600 having, in its embodiments, an inflatable reflector apparatus 610 comprising a 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 for (1) heating and cooking, (2) electrical power generation, (3) enhancing the transmission and reception of radio signals, (4) enhancing vision in low-light environments, and/or (5) projection of optical signals or images. The device also has non-electromagnetic uses, such as the collection and storage of water, harnessing of energy from a fluid stream, and/or harnessing wave energy. A first main embodiment of the inflatable reflector apparatus 610 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 610, the modular apparatus 600 typically further includes modular assemblies to increase versatility, facilitate use, and/or enhance safety such as, for example, a modular support and orienting assembly 612, a separate support ring 614, a safety shield or cage 616, a focal point support assembly 618, a safety cover 620, a safety net or mesh 622, and a stabilizing assembly 624. Portability is enhanced by complete collapsing of the inflatable device.

Bio-electrochemically assisted microbial reactor that generates hydrogen gas and methods of generating hydrogen gas

Systems and processes for producing hydrogen using bacteria are described. One detailed process for producing hydrogen uses a system for producing hydrogen as described herein, the system including a reactor. Anodophilic bacteria are disposed within the interior of the reactor and an organic material oxidizable by an oxidizing activity of the anodophilic bacteriais introduced and incubated under oxidizing reactions conditions such that electrons are produced and transferred to the anode. A power source is activated to increase a potential between the anode and the cathode, such that electrons and protons combine to produce hydrogen gas. One system for producing hydrogen includes a reaction chamber having a wall defining an interior of the reactor and an exterior of the reaction chamber. An anode is provided which is at least partially contained within the interior of the reaction chamber and a cathode is also provided which is at least partially contained within the interior of the reaction chamber. The cathode is spaced apart at a distance in the range between 0.1-100 centimeters, inclusive, from the anode. A conductive conduit for electrons is provided which is in electrical communication with the anode and the cathode and a power source for enhancing an electrical potential between the anode and cathode is included which is in electrical communication at least with the cathode. A first channel defining a passage from the exterior of the reaction chamber to the interior of the reaction chamber is also included.

Anaerobic digester system and method

An anaerobic digester system has a vertically upright vessel, a matrix arranged in the vessel supporting a microorganism biomass thereon, an input for supplying an input slurry of liquid and suspended solids at an upper portion of the vessel above the matrix, a gas output at the top of the vessel for withdrawing gas generated by anaerobic digestion of solids, and an effluent output at the bottom of the vessel for withdrawing liquid and remaining solids. The vessel has a preferred liquid height to diameter ratio of 2 to 1, and is constructed of inert fiberglass-reinforced plastic coated with a translucent blue gel pigment layer for filtering light at wavelengths that promote biomass cultivation. The matrix is formed as an array of panels mounted to a spindle with wheels fixed at spaced intervals along its vertical height, and the panel are made of a polyethylene grass matting providing a high surface area to volume ratio of at least 20 to 1. Gas from the top of the vessel is recycled to the bottom to generate bubbles for mixing the feedstock. The related method of anaerobic digestion includes comminuting input wastes with a slurry grinder into a pumpable slurry 8-10 % by weight solids, and providing as the biomass hydrolytic bacteria, and fermentative bacteria including acetogenic and methanogenic bacteria to produce a methane gas product. Other products include an organic soil additive, bacterial solids plant food, and a filtrate used as plant tonic.
