      JoeF made an excellent observation that the varidrogue is a solution to controlled power lifting. Previous schemes mostly relied on a crane-like power reel on the ground supposing that kite power would wastefully descend then reascend. But the varidrogue provides working power at altitude. For example, a small varidrogue at each wingtip of a giant kite could steer forcefully with minimal control actuation input.
       
      The tritether was recently identified as a switching amplifier, a sort of stringy transistor, & so is the varidrogue (which contains a tritether), but with the advantage of accessing motive power directly. The windfield is thus a convenient distributed power bus to drive logic/power operations anywhere in a kite network.
       
      Brooks made a great point about a reversing drive line avoiding some hassles of a loop drive & he sees how a mechanical flip-flop is a simple method of line reversing. By cross-linking two varidrogues with the kill lines passively cycled a giant "soft" flip-flop can be created without a "hard" mechanism. This would drive a double spraged generator nicely.
       
      Varidrogues are easily cascaded where a tiny varidrogue acts on the kill line of a larger varidrogue (or multiple varidrogues), which in turn acts on a larger varidrogue, up to vast scales. A vvery potent AWE design language has emerged that is logically comparable to electronics.
       
      A very elegant application of varidrogue lifting is to pull thin bags of air deep underwater against an bottom anchor pulley. A high pressure hose to the surface would be a quality energy fount to drive all kinds of processes like, say, desalination. The prechilled air would depressurize at useful refrigeration temps. All this with but string & membrane.
       
      The tethered aviation revolution flies on the kitey power of simple low mass string & membrane technology, with fairly universal applications. AWE based on non-kiteyness kills the magic.
