I don't see why a wind system would be needed. It's just another form of power like invisible imaginary diesel engines turning propellers. Catching the wind could be controlled by what the throttle buttons do now. All the other extra controls of sails and stuff would be automatic, no need to fill up the whole keyboard with controls, that's what the imaginary crew is there for. Just like the imaginary crew oils the Vermaas's engines, scrubs the barnacles off the hull, and serves noodles on odd days and meatloaf on even days, while I, as captain, spin the wheel and toot the horn. Oh, c'mon, you know what I mean: those little Troninites that run around inside the computer making stuff happen. I'm just a user.
