Transforming Organic Waste into Renewable Energy Solutions
ITility’s renewable energy technology is based on Anaerobic Digestion (AD), which uses processes where microorganisms break down biodegradable material in the absence of oxygen. When integrated into a waste management system, AD reduces operational carbon footprint and the emission of greenhouse gas into the atmosphere normally associated with decaying organic waste. Two outputs from this process are nutrient rich digestate usable as fertilizer and methane rich gas, commonly known as biogas. More than half of biogas is methane (natural gas) which is usable as a renewable energy source. The digestate can be land applied, composted and used as a soil amendment, or processed into fertilizer types. Biogas can be combusted in an engine to power a generator for creating electricity. In addition to the electricity, a large amount of heat energy is also produced which can support system processes or diverted to other onsite power functions. While AD technology is not new, ITility’s processes that create efficiencies, scalability and flexibility for the warfighter are transformational in the renewable energy domain. The impact of ITility’s renewable technology processes make it both economically viable as green energy and operationally advantageous in expeditionary environments to extract energy from organic waste.
Photochromic Film a.k.a. Chameleon film(tentative name), auto-tinting films
Through the cooperated works with companies in developing new chromogenic materials that can be deposited below 150oC, we successfully demonstrate the flexible photochromic film that can reversibly tune its transmittance in response to sun light. While it has an average transmittance of 70% at 600 ~ 700nm at its original state, it turns to greenish blue with 20% transmittance at 600 ~ 700nm upon exposure to sunlight. As the previously fabricated photochromic glass, photo-switching time of this photochromic films are not affected by their dimension. Switching time for coloring and bleaching is not the same. While the former is about 5min, the latter takes much longer time, about 5 hours. Now we focus on optimizing switching time for bleaching under dark condition by carefully tuning material’s composition. Our photochromic film does not need external power to operate that can greatly reduce expenditure of installation and maintenance.
Innovative Engine Systems
Various non-ICE (internal combustion engine), non-nuclear and emission free systems are configured to effectively manage working medium in cyclic system directing mass flow of medium as (potential) energy to drive, or propel, a custom turbine (kinetic) machine to produce torque motor horsepower in demand, whereby, appropriate transmission delivers revs/rpm as specified for generator, wheels, propellers, impellers and other mechanical application.
Advanced Ozone Based Water Purification
Roving Blue, Inc. manufactures and distributes ozone based water purification components and systems. Ozone is a form of oxygen. It is a highly effective germicidal agent and is a powerful oxidizer; it is, in fact, stronger than chlorine, and is used worldwide in water purification, water and wastewater recycling, and food production. To make ozone, you need oxygen. This is typically obtained by using a method called “corona arc”, which uses the oxygen in the air or bottled oxygen gas. Roving Blue’s ozone technology is electrolytic; we make ozone out of the oxygen in water itself - the “O” in H2O.
Twistact technology comprises a pure-rolling-contact device that transmits electrical current between a stationary and rotating frame (or two rotating assemblies having different speeds and/or direction of rotation) along an ultra-low resistance path (e.g. 1 milliohm). Twistact devices accomplish this pure-rolling-contact galvanic connection using a flexible, electrically conductive belt and a matching set of epicyclic sheaves. Laboratory testing has proven that a single Twistact device will be capable of operating over the full 30-year service life of a multi-megawatt direct-drive wind turbine without maintenance or replacement. A technoeconomic analysis undertaken by NREL on behalf of DOE determined that the substitution of rare-earth magnets with a wire-wound rotor and Twistact module in a 10 MW direct-drive wind turbine eliminates the need for rare earth magnets without incurring any penalties in power generation efficiency or levelized cost of energy (LCOE).
