Abstract: An integrated multimode thermal energy transfer system, method and apparatus for full-scale clean fuel electric-powered multirotor aircraft with automatic on-board-capability to provide sensor-based temperature awareness and adjustment to critical components and zones of the aircraft. Automatic computer monitoring, including by a programmed triple-redundant digital autopilot computer, controls each motor-controller and motor to produce pitch, bank, yaw and elevation, while simultaneously measuring, calculating, and adjusting temperature and heat transfer of aircraft components and zones, to protect critical components from exceeding operating parameters and to provide a safe, comfortable environment for occupants during flight. By using the results of the measurements to inform computer monitoring, the methods and systems can use byproducts including thermal energy disparities and differentials related to both battery systems and power generating systems to both add and remove heat from different aircraft zones to improve aircraft function, comfort, and efficiency.

Abstract: An internal gear pump or motor includes inner and outer rotors that mesh together. An internal electric motor or generator may include a stator supported by a support element that passes through bearings of the outer rotor and the inner rotor may act as a rotor of the electric motor or generator. With or without the stator, the support element may support bearings of the inner rotor. The support element may be, for example, an eccentric shaft. Fluids may be supplied via the support element, if present, for cooling, lubrication or to flush a working fluid out of portions of the pump or motor, such as bearings. Flushing may also occur via channels in the housing with or without the presence of the support element. Axial faces of one of a pair of adjacent elements, for example the inner rotor and the outer rotor, may include portions for improved axial sealing and wearing in of the other of the pair. Fluid may enter and exit chambers between the inner and outer rotors by radial ports

Abstract: Methods and apparatus for decoupling reactant activation and reaction completion. Various embodiments of the present disclosure leverage electrodynamic inversion principles to provide fuel cell-like operation. In one exemplary embodiment a fuel cell-like apparatus is configured to: create reactant ions (e.g., fuel ions, oxidant ions, etc.) in isolation, transport the reactant ions to a reaction interface, enable a chemical reaction, harvest the resulting electrical current, and eliminate the exhaust products. The exemplary fuel cell-like device decouples the reactants from directly powering the load. Notably, the redox reaction is allowed to proceed at a reaction interface rather than directly at the anode and cathode.
