One of the principal advantageous & innovative design feature adaptations integral to the HAWG's ability to efficiently extract several times more energy (over conventional wind turbine designs) from any given wind resource is the concept of the Diffuser-Augmentor-Concentrator, which beneficially encircles and enshrouds the contra-rotating variable-pitch wind turbine blades. This basic design principal was verified by Grumman Aerospace, where wind-tunnel tests showed that a shrouded wind turbine produced four times more power (400%) over unshrouded wind turbines. Green World Technology advanced the shrouded/augmentor wind turbine design concept advantage considerably by creating a unique thick-cord ring-airfoil lifting-body concomitant with judicious applications of a NASA innovation called "micro-vortex generators" which control airflow where necessary to prevent boundary-layer separation and in doing so greatly enhance the wind energy extraction process.

Another advantage inherent to the HAWG design in its ability to extract wind energy efficiently and generate prodigious electrical power lies in its ability to operate without the complexity, weight and associated maintenance and capital costs of a transmission/gearbox assembly typically installed in commercial wind turbines. The "gearbox-free" high-speed variable-pitch wind turbine blade array allows the HAWG to begin producing useful power at lower wind velocities and continue to safely produce & deliver power at ambient wind speeds which would damage conventional commercial wind turbines.

The HAWG is inherently avian-friendly and in theory bird-safe, owing to the stationary nature of the craft while in generator mode, and the highly-reflective, closely-spaced contra-rotating wind turbine blade arrays. A bird will likely see the shiny, closely-spaced rapidly moving blade arrays and perceive it as an impassible solid object, in contrast to the conventional wind turbine blade array which appears to the bird as "open flying space" (with occasional tragic consequences to the mistaken bird). Bright LED anti-collision clearance lights and spotlights directed to the reflective spinning turbine blade surfaces will visually alert all adjacent sentient air traffic, feathered or otherwise.

The HAWG is a hybrid design owing to a dual purpose centrally located dynamo which can operate either as an electrical generator driven by wind passing over variable-pitch turbine blades in stationary generator mode, or the dynamo can operate as a powerful electric motor driving the same variable pitch turbine blades for propulsion in free-flight remotely-piloted transport mode. The HAWG can fly direct from its origin factory location to its mooring point at the generator base station. There, any excess power produced (ex: during off-peak times) can be used to produce large quantities of NH3 (anhydrous ammonia) from air and water, which can be safely stored indefinitely at relatively low pressure (~10 bar or ~150 psi). During periods of high electrical demand, or infrequent lulls in wind energy, stored NH3 (ammonia is a very concentrated form of hydrogen) can be used by dedicated utility  fuel cells to meet real-time electrical grid demand requirements in excess of the HAWG electrical output. Additionally, NH3 can positively reduce transportation-sourced CO2 emissions, as most vehicles which now burn carbon fuel(s) can also convert to operate on carbon-free ammonia.

The HAWG can also provide a working platform for other essential services besides clean, carbon-free power. Moored at a relatively modest 2,000 ft. altitude, a telecom/wifi-equipped HAWG offers the exciting possibility of wide-area mobile telecom service coverage, as well as strong, reliable high-speed broadband internet service. The ability of the HAWG to fly to and moor anywhere, means mobile phone and wifi service can now be provided anywhere too. Accordingly, to greatly improve and expand world-wide telecom and internet service and promote and complement the current international government and telecom industry research & development efforts, Green World Technology has launched  a new collaborative research project: High Sky Wifi.
