It could fit the definition of an energy kite system, an AWES, a paravane that has parts deflecting the air media besides the water media. Fine tune or down select resultants by carefully designing the hull and sail and control parts and do various good works with the machine, perhaps generating electricity. Left-right cycles with PTOs could generate airtricity and hydro-electricity, thus kitricity. Similarly for anchored freighter ships! And look for even larger hulls dedicated to energy generation anchored to seabeds! Tap the ocean currents with such devices. Minesto is part of a potentially huge family of AWES using the seas. Think GW units! A moored platform might feature all the following: hydroelectric generation, air-kite airtricity generation, towered turbine electric generation, PV, production of hydrogen or other chemicals.
