    Abstract: A reconfigurable unmanned aircraft system is disclosed. A system and method for configuring a reconfigurable unmanned aircraft and system and method for operation and management of a reconfigurable unmanned aircraft in an airspace are also disclosed. The aircraft is selectively reconfigurable to modify flight characteristics. The aircraft comprises a set of rotors. The position of at least one rotor relative to the base can be modified by at least one of translation of the rotor relative to the boom, pivoting of the boom relative to the base, and translation of the boom relative to the base; so that flight characteristics can be modified by configuration of position of at least one rotor relative to the base. A method of configuring an aircraft having a set of rotors on a mission to carry a payload comprises the steps of determining properties of the payload including at least mass properties, determining the manner in which the payload will be coupled to the aircraft, determining configuration for each of the rotors in the set of rotors at least partially in consideration of the properties of the payload, and positioning the set of rotors in the configuration for the aircraft to perform the mission.

    Abstract: Described embodiments include a system and a method. A system includes an energy storage device configured to store and release energy. The system includes a waveform sensor configured to detect a second harmonic or higher frequency component deviation in a waveform of electric power supplied to the system by an electrical power grid. The system includes a bi-directional switched-mode converter coupled between the energy storage device and the electrical power grid. The switched-mode converter is configured to receive and convert electric power from the electrical power grid into energy stored in the energy storage device and to convert energy released from the energy storage device into electric power and discharge the converted electric power into the electrical power grid. The system includes a waveform correction manager configured to control the bi-directional switched-mode converter in a manner implementing a waveform deviation reduction strategy responsive to the detected deviation in the waveform.

    Abstract: A cooling system for a subterranean power line may include a cooling tube configured to house a fluid. Heat generated by the subterranean power line may be radiated and/or conducted to the cooling tube and absorbed by the fluid within the cooling tube. As the fluid heats up, it may change phase from a liquid to a gas. The hot gas may rise to a heat-exchanging condenser configured to dissipate the heat and condense the fluid back into a liquid. The cool, condensed liquid my return from the heat-exchanging condenser to the cooling tube. Risers, gas transport tubes, pressure regulation systems, fluid storage tanks, and other components described herein may increase the efficiency of the cooling system and/or otherwise improve the viability of the cooling system for subterranean power lines.
