Ion Harvesting Technology harvests high voltage electricity, including from atmospheric ions. A wire, or conductive tether, may be used to connect ion harvesting material (typically carbon, but including any materials such as metals, metamaterials, or others) located on or near an aerial platform to an anchor point. Because the harvested electricity is typically of high voltage, the electricity may arc between the conductive tether to nearby points of lesser or greater voltage. Such arcing represents a loss of power to the overall system, causing the overall system to be less efficient, or possibly non-operational, and in some cases may cause catastrophic system failure. Electrical isolators may be used to prevent the losses from the arcing.

A tethered aerostat with a ground based deployment, extended duration and recovery system to accommodate a weather vaning deployed aerostat while maintaining a supply of a lift gas by having a rotatable tether pipe and a hollow tether. Included is a rotatable tether pipe device assembly with rotor and stator components disposed in an air tight housing assembly to provide a ground based gas maintenance system. An aerostat deployment buoyancy control maintenance and combined recovery platform is provided. The tethered aerostat systems and method increase deployment duration and allow more systems to be controlled and maintained on the ground without interrupting aerostat operational capabilities.

A buoyant aerial vehicle includes: a balloon configured to store a gas; a payload coupled to the balloon; and a propulsion unit coupled to the payload by a tether. The propulsion unit includes: a fuselage having a substantially longitudinal shape, a first end, and a second end; a primary airfoil coupled to the fuselage; a secondary airfoil coupled to the fuselage at one of the first end or the second end; and a thrust generating device disposed at one of the first end or the second end and configured to move the propulsion unit relative to the payload along a propulsion flight path. The movement of the propulsion unit imparts movement of the buoyant aerial vehicle along a vehicle flight path.

Systems and methods are disclosed for determining a vehicle elevation height for launching an unmanned aerial vehicle. Example methods may include performing a quantitative balancing analysis using baseline factors, establishing optimal values for operational goals of a vehicle based on the quantitative balancing analysis, determining a vehicle elevation height that achieves the established optimal values for the operational goals of the vehicle by evaluating vehicle delivery parameters using normalized values, and initiating on a winch system elevation of the unmanned aerial vehicle to the determined vehicle elevation height for launching.
