An energy delivery system includes: a solar cell configured to receive solar energy and generate electrical energy; an electrolysis module configured to generate a first fuel from water; a fuel cell configured to generate electricity by reacting the first fuel with a second fuel through an electrochemical reaction, wherein the electricity is used to power a movable platform; and a controller configured to generate instructions for the solar cell to provide the electrical energy to one or more of: (1) the electrolysis module to effect operation of the electrolysis module, and (2) the movable platform.

A solar powered aircraft including a modular main wing and a pair of relatively large modular winglets attached to the transverse end portions of the main wing. To collect solar radiation, including relatively low-angle radiation, solar panels are mounted to both the main wing and the winglets. In some embodiments, the aspect ratio of the main wing is relatively low, such as between 9 and 15, i.e., the main wing is relatively deep compared to its wing span. In some embodiments, the winglets are relatively long, such as in the range of 0.2 to 0.7 times the length of the main wing semi-span. In some embodiments, a truss-like spar passes through and helps support the wing and the winglets.

An unmanned aerial vehicle includes a central body having a plurality of sides and a plurality of arms extendable from the central body. Each arm is configured to support one or more propulsion assemblies that provide a propulsion force while the unmanned aerial vehicle is in flight. The arms are configured to transform between a flight configuration in which the arms are extended away from the central body and a compact configuration in which free ends of a first subset of the arms collectively define a rectangular area. Free ends of a second subset of the arms are closer to a yaw-axis of the unmanned aerial vehicle than the free ends of the first subset of the arms. The yaw-axis passes through the rectangular area.

A drone-assisted ballistic system is provided. The ballistic system may include a plurality of mobile devices, a ballistic computer, and a data interface. Each mobile device may be operable to gather wind data along or adjacent to a flight path of a projectile to a target, each mobile device measuring at least wind speed and wind direction. The ballistic system may include at least one static device operable to gather wind data at or near a launch or firing position. The ballistic computer may be in data communication with the plurality of mobile devices to receive the wind data. The ballistic computer may be configured to calculate a wind compensation value for the projectile based on the wind data. The data interface may be in data communication with the ballistic computer to output the wind compensation value to a user in real-time.

A ducted-fan unmanned aerial vehicle (UAV) capable of low-energy high-rate maneuvers for both vertical roll control and horizontal pitch control. The maneuverability of the UAV is enhanced by equipping the ducted fans with respective piezoelectric-actuated thrust vectoring flaps. Thrust vector control is achieved by controlling the angular positions of a plurality of thrust vector flaps pivotably coupled at respective outlets of a plurality of ducts having fan rotors at the inlets. Each thrust vectoring flap has only one degree of freedom in the frame of reference of the UAV, namely, rotation about a single axis that is perpendicular to the axis of the duct. The angular position of the flap is controlled by sending electrical signals to a piezoelectric actuator (e.g., a piezoelectric bimorph actuator) having a voltage sufficient to cause the piezoelectric actuator to bend.

Systems, methods, and devices are provided herein for removing a byproduct of a fuel cell from a vehicle. The vehicle comprises a fuel cell and a venting system. The fuel cell is in communication with a fuel storage container. The fuel is configured to generate electricity and a byproduct, by reacting a first fuel from the fuel storage container with a second fuel through an electrochemical reaction. The venting system is configured to expose the byproduct to forced convection.

A method is described to reduce Global Warming by reflecting solar irradiance. Thin reflective sheets are flown under control in the upper atmosphere above Earth, in contrast to reflecting from Space orbits or the ground. The high altitude enables nearly total reflection. Two general embodiments use translational and/or rotational motion of the sheets to hold sheets stretched while providing aerodynamic lift, while a third uses buoyant aerostatic lift. During the daytime solar power is used. During the night the low wing loading of the sheets facilitates gliding flight without descending into controlled airspace. Sheets can be arrayed to increase aspect ratio and decrease induced drag. By following the summer sun, effectiveness is increased. A swarm of reflectors around the south Polar Circle can reduce summer melting of ice enough to reverse the rise in sea level.

An autonomous remote device for deployment in an area, comprising: a mechanism for launching the device airborne from a first of a plurality of locations; a mechanism for navigating the device when airborne to a second of the plurality of locations; and a mechanism for landing the device at the second of the plurality of locations.

A set of images of a three-dimensional (3D) inspection object collected by a drone during execution of a first flight path may be received, along with telemetry data from the drone. A tagged set of images may be stored, with each tagged image being stored together with a corresponding drone position at a corresponding time that the tagged image was captured, as obtained from the telemetry data. A mapping of the set of tagged images to corresponding portions of a 3D model of the 3D inspection object may be executed, based on the telemetry data. Based on the mapping, at least one portion of the 3D inspection object omitted from the set of tagged images may be identified. A second flight path may be generated for the drone that specifies a position of the drone to capture an image of the at least one omitted portion of the 3D inspection object.

Example methods, apparatus, systems, and machine-readable mediums for an artificial intelligence platform for mobile charging of rechargeable vehicles and robotic devices are disclosed. An example method may include determining that a mobile vehicle is operating within a region and determining that the mobile vehicle requires charging of a battery for the mobile device while operating within the region. The method may further comprise identifying a charging station available within the region for charging of the battery at a time and a location within the region and navigating at least one of the mobile vehicle or the charging station to the location at the time for charging the battery of the mobile vehicle.
