      ***** What is a state machine?

      A state machine is the set of logically discrete states of a dynamic system. It is used to formally model and simulate engineered systems, to "run" and debug them, and often takes the form of a multidimensional matrix. A staged rocket is an example of a staged state machine in action, where each rocket stage is a discrete state to step thru. A Rube Goldberg machine is a passively-staged state machine, in that each stage triggers the next without active control.
       
      For an AWES, a passively staged launching and landing stage machine might go like this- 1) a tiny pilot kytoon awaits wind aloft. 2) Wind comes and the kytoon pulls a pilot-lifter kite up into the wind. 3) The pilot-lifter lifts a larger pilot lifter, and so on until the cascaded launch sequence has lifted the final scale of kite aloft. 4) Heavy power elements like rigid wings and FEGs can follow naturally and power generation occurs. Early stage elements trail in a compliant furled mode, 5) The wind either builds to excess or dies, but simple mechanisms detect either case to reverse the launching order. 6) Each stage self-kills in sequence and the system returns to its starting state, ready to repeat.
       
      KiteLab has done many variations of passive-staging. It looks ugly, but works surprisingly well. The prediction is that highly optimized simplified designs can emerge from continued R&D. Here is an old video of simple passive staging-
