Launch hang gliders by use of a kite system?
Kites launching kites is a meta parent to kites launching kite hang gliders.
There are many ways to use kite systems to effect the launch of a free-flight hang glider.  [Note: The trivial case is that some hang gliders are already a kite system.]

We are in draft mode on this folder of files for a hang gliding community launch project; we certainly invite notes from all; please send your notes by e-mail:
LaunchByKite@worldhangglidingassociation.org    as you choose to advance this concern. There is large room and opportunity for very many people to advance launch-HG-by-kite systems.  It is anticipated that sharp practical solutions will be being placed on the option table throughout the entire 21^st century. Any tiny contribution advancing these techniques could be fun and eventually helpful.  Artists and cartoonists are invited to the technical play. Go for sport or practical uses.

The discussion topic that faces a kite hang glider in itself without further kite systems involved for the launch, is the purist situation well developed in conventional hang gliding literature.  This purist category may involve such as direct launching of one's hang glider by foot, incline rolling, incline skiing, ...   Such methods involve jumping up into lift from flatland (using fence lift perhaps) or using the potential energy obtained by moving the hang glider to a high point (platform, inclined ramp, slope, hill, mountain, building). Moving a hang glider to a point where potential energy of height may be used for self-launching of the kite hang glider is frequently done by walking, hiking, getting assist from carriers (friends, cars, trucks, buses, helicopters, airplanes, trains, blimps, horses, dogs, etc.); note, such carriers are carriers only, not launch tugs.  Other carriers may be space-reentry vehicles with the hang glider deployed from the spacecraft. Or a hang glider might launch from the interior or exterior surface of a powered aircraft. Or released from a balloon system. This category occupies the major part of hang gliding literature.    Rather, we spend attention now below on less-direct launch methods that use a kite system to launch hang gliders into free-flight gliding and soaring. 

Varieties of kite-system launching hang gliders into free-flight gliding and soaring: (collection is not yet complete; all are welcome to advance the topic)

• Pilot climbs up to the lofted-by-kite arrangement after the HG is lifted by the kite system. The arrangement aloft may be varied. Hang and release is one choice. Another is to have an aloft platform. Perhaps held aloft is a tent or home where hang glider pilots may rest or party before launching off the kite-held things.
   
• Pilot is lifted with the HG by a kite system.
  • Pulley method once kite system is launched.
  • HG with pilot mounts kite; kite then zooms to then release the piloted HG. 
    • HG may be the high hat to the lifting kite.
    • HG may be hung from the lifting kite and then released at will of the pilot.
    • HG may be as the tail of the lifting kite and then released at will of the pilot.
    • HG may be hung from the main tether of the lifting kite system and then released at will of the pilot.
    • HG may be hoisted up to release altitude, all of which is supported by the macro kite system.
    • HG may be slung via main kite-system tether tension after tether is set down or pulled down to trigger point.  This slinging may be using an arrangement from ordinary position of a kite tether or from other arrangements that mimic a Y slingshot.
       
  • Conventional aerotow of HG is a kite system using a powered aircraft; that powered aircraft also might be an electric aircraft which electricity could be obtained by a kite-energy-system. The powered aircraft could be either robot-controlled in untethered flight or robot-control, but tethered or human-piloted.
     
• Pilot is delivered to the lifted-by-kite system via secondary means.
   
• Kite system holds artificial slope or ramp; pilot carries HG up the artificial slope.
   
• Kite system holds up artificial slope or fence; pilot jumps off flats into the lift zone formed windward of the held slope or fence. See suggestive video in Google video.
   
• Kite system is used as a tug source for launching hang glider.
  • Dynamic free flight system where HG is the lower second-to-fly end of the free-flight tether.
  • Kite system tugs through two separated field pulleys without any line-speed multiplier.
  • Kite system tugs through two separated field pulleys with a line-speed multiplier.
     
• Kite system is used in a kite-energy-system format to generate electricity to be used to launch a hang glider. The electricity may be used immediately or stored for later use in one of these methods:
  • Power an electric winch to skyte the HG in conventional manners.
  • Power an e-powered harness via cable to source of electricity either onboard or remote
  • Power an electric winch for towing up a hang glider.
  • Power a electric aircraft which would then aerotow the hang glider.
  • Charge air-framed ultracapacitors that would power an e-harness on air-frame-held motor for pulling or pushing propellers for power-assist launch.
  • Power a power-beam gun for remote powering onboard power-assisted launching of HG.
     
• Kite system is used in a kite-energy system format to pump water to a high reservoir. Let the water drop with a drogue chute in the flow; let the drogue be tethered which tether tugs a hang glider for its launch.
   
• When the kite system is the hang glider itself with an extended kite line from the kite-glider (wing and/or pilot-connect) to a powered aircraft. Such aerotow launching is faced in extensive literature on aerotow of hang gliders (AT).
   
• When the kite system is the hang glider itself  and a fixed ground mooring is used in ambient winds is self-kiting with its special challenges and niche purposes.  Bridge-hung. Balloon-hung.
   
• When the kite system is the hang glider itself  but towed by a
  • moving boat or ship or jet-ski
  • moving car or truck using a static-length tow line
  • moving car or truck using a tension-controlling payout reel
  • moving car or truck using a tension-controlling payout winch
  • moving embedded-in-river drogue chute or embedded-in-river paravane
  • moving embedded-in-river paravane.
  • 
     
• When the kite system is the hang glider itself using fixed-length extended long tether to fixed ground anchor.
   
• Single-bungee line launch self-set with bungee left on ground after triggered use for launch.
   
• Single-bungee line launch self-set with line winched aloft after launch is effected.
   
• Dynamic system where moving paravane and long-line air-kite HG use ambient wind. At selected time, the HG releases.
•  

Kite-system choices for the tasks of tug or electricity-production

• The kite-hang glider itself only with no extended tug line.
• The kite-hang glider itself with extended tug line without further paravane or kite system.
• Single wing kite beyond the HG.
• Multiple wing kite with back-to-front stack train.
• Multiple wing kite with branching from main tether.
• Multiple wing kite in coterie
• Multiple wing kite in tree with various-natured branching.
• Multiple-wing kite in simple arch.
• Multiple-wing kite in arch where arch branching may each be trains, stacks, coteries, clusters,
• Multiple-wing kite in grid.
• Cluster of single-wing kites each wing having its own entire line brought to a single mooring point which mooring point may be positioned in any working system.
• Cluster of trains, stacks, trees, coteries, arches, etc.
• Or element wings spawned from viewing Kite types.

Some starters:

Possible applications of launch-HG-by kiting:

• Traverse nations or world or oceans.
• Play new games.
• Have method as platform for a new sport.
• Solve a particular challenge.

========================================

Unbaked only-possibly related flashes:

• Landing via drop a line to water; have water chute at dropped end; glide into tensed-tether position; beginning macro kiting; control system into a kited landing.
• Rotating arm with tether connected to HG.
• Landing into kite-lofted high nets.
• Catapult masses raised by using kite power either directly or via kitricity use. This includes pumping water to high position to provide catapult draw.
• Struggle and evolution of rock climbing given some model to hang gliding.
