摘要： Systems, apparatuses and methods for harvesting ambient energy involve an electrically conductive charge-carrying movable electrode. An apparatus includes an electrically conductive charge-carrying electrode, a first dielectric interface region, a second dielectric interface region, and at least one reference electrode. The first and second dielectric interface regions differ in surface charge density. In certain aspects, the movable electrode moves proximate and relative to the first and second dielectric interface regions in response to receipt of ambient energy, thereby providing first and second capacitances. The first capacitance differs from the second capacitance, and/or the first surface charge density differs from the second surface charge density. Movement of the movable electrode in combination with the differing capacitances and/or charge densities results in energy accumulation, thereby enabling ambient energy to be harvested efficiently and effectively.

摘要： A system and method for converting organic wastes to biodegradable thermoplastic materials including polyhydroxyalkanoates is disclosed, which method includes treating the organic wastes with an acidogenic microbial population to form fermentative organic acids, and polymerization of the organic acids by PHA-producing microbial species to form PHAs. The system includes a first compartment for acidogenesis of organic wastes without oxygen, and a second compartment, for polymer synthesis by enriched cultures of species with oxygen such as R. eutropha, P.oleovorans , or mixtures thereof. The compartments are integrated with barriers that permit mass transfer of organic acids while maintaining different culture conditions in the compartments.

摘要： Disclosed herein is a system and method for energy generation from salinity gradients using asymmetrically porous electrodes. In certain embodiments, an energy generation system includes at least one pair of asymmetrically porous electrodes positioned within a chamber in selective fluidic communication with a freshwater source (e.g., a river) and a saltwater source (e.g., an ocean). Asymmetry between a first average percent volume per unit pore-width of a first electrode and a second average percent volume per unit pore-width of a second electrode creates differing interfacial potentials between the first electrode and the second electrode when such electrodes are immersed in freshwater and saltwater. By cyclically immersing the electrodes in freshwater and saltwater, energy is harvested from Gibbs free energy from mixing saltwater and freshwater. Such a system does not require a membrane or an external charge source. Methods of generating energy using asymmetrically porous electrodes are also provided.

摘要： Apparatuses and methods for harvesting ambient energy involve repeated circuit reconfiguration. An apparatus includes a primary charge storage device, a first secondary charge storage device, a second secondary charge storage device, and switching circuitry. The switching circuitry is configured to cyclically alter connection of the first and second secondary charge storage devices between a series state and a parallel state. First and second moveable electrically conductive elements may include electrically conductive liquid droplets of materials such as water or mercury. At least one of the primary storage device, the first secondary charge storage device, or the second secondary charge storage device includes a capacitance that varies in response to receipt of ambient energy. Concurrently altering relative capacitance and circuit configuration results in exponential growth of harvested energy.
