Ddrone, Sandaerodrone is a safe, weightless, H2/H2O aqua-eolic-solar, modular multicopter-airship for DELIVERY, advertising, filming, security, emergency, communication and energy. 4D HAI (Human Artificial Intelligence Network) lidar/radar/sonar/camera self/remote/teledriving adds the dimension of TIME, looking at past+present data to extrapolate future defensive scenarios. Ideal to operate near and over people with cushioned low impact structure. Floats on air recharging or slowly descends if runout of energy.
Sandaerodrones can join Sandaerotrain or connect/pick-up a Sandaerocar Ocar, turning it into a Sandaerocar Acar, that can join the cabled system Sandaerotrain. Ocar can also join directly track or tunneled output solar/wind energy systems with 3 level system varying in speed and stops. Ocar modular composite cube sphere short hop-flies over intersections, obstacles, traffic, rivers and up to connect to Ddrones to form Acar with unlimited solar-wind-water energy production storage.
Ddrones can supply extra energy/battery, passenger/cargo capacity and flying time for Sandaerocars (Ocar, Acar, Hcar) and Sandaeroships, attaching/switching on the move, bringing the energy supply station to the vehicle and/or increasing the solar-wind-water recharge/storage capacity. Economies of Scope Flexible Multiple Product Just-In-Time Local Production Ddrone Delivered Directly to buyer eliminating retail/wholesale, connecting producers directly to consumers. Acar zero-weight standard configuration has 11 lighter-than-air buoyant Ddrones (G$2950/module), 1 heavier-than-air Ocar (G$9950/module), with target price of G$39950, produced in tax-free Globocean, international waters.
