More Varidrogue Tricks
- 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.
