is a growing file; known methods are not yet comprehensively posted in
list.)
Target:
Open a folder on each method or option; post related discussion
notes and links.
All are invited to send notes on proposed
or achieved methods of making and collecting energy from kite systems. If
the title is still black, then the folder has not been started yet.

Big milestone reached: M2917
Jan. 15, 2011. "New Persistent Flight
Principle Demonstrated (Pumped Tri-Tether)" by
inventor Dave Santos.
Reel, reel-in and reel-out, Yo-yo, pumping
Rail-car
Sailed rail car
LoopTether or single loop tether through one ground generator or
"FanBelt" where aloft actions cause the tethering belt to drive
the generator
Single-loop through two ground pulleys
Flipper
Sputnik
Wriggle line
Undulations in tether tension with cycle short or long.
Uno-line reciprocator. Duo-tether reciprocator. Tri-sub-tether
reciprocator. Long-cost phase or very-short cost changeover cusp
at change. Smoothing devices. Lois, Loyd, Santos, Faust, and others.
Kite or kytoon lifted tensional towers which towers hold various
wing formations that drive torsion tubes
Torsion tube with main
tether through hollow torsion tube and hollow generator shaft to aft
winch/reel; wings attached to torsion tube. See
SpiralAirfoil Airborne Division.

NOTICE. Torsion using set of bladed turbines driving
ground generator; AWE system lifter by balloons and parachute; same could
be lifted by kite or kytoon or combinations of lifters.

Lifted loop; loop driven by circling low-mass
kite that drives lofted lever; lever drives upper gear that drives loop;
loop at base station drives generator. Simple. All elements
are scalable for mining high-altitude wind.
Drawing.
VariDrogue in several formats: (these differ from the
straightforward reeling method of in and out from AoA changes or massive
shape changing on flying wing)
Single tether to lifter with variDrogue at midline cycling
open/close to operate groundstation levers driving pump or generator
Single lifter with variDrogue being at the lifter itself with
cycling drag on and off for tether to drive groundstation levers or
booms to drive generator or pump
Two separate lifters with separation and each having a mid-tether
variDrogue (or being at lifter with variDrogue being lifter) with
alternating the phase of the two variDrogues to drive tether to drive
groundstation gear on generator or rocker arm.
Two missing AWE solutions-
A Traction Kite can sequentially pull the legs of a
string tripod to generate energywith
wind from any directionwithout
resetting leg anchors.
Sequentialtensioning&
slacking of the legs of a string tripod can maintain a kite
aloft in calm by towing it in circles. Similarly a kite can be
kept aloft by towing back & forth between two anchors.
Large expensive
turrets, carousels, or circular/oval tracks are rendered unnecessary

Spread of two coupled kites pulls center of central bridged-held
line; bring the coupled kites toward each other to release downwardly
the center of central bridged-held line; the central-bridge-held line
pulls and releases in cycles to drive sprag-clutched ground gen.
The working line could be springed tensed or worked from another third
spreading kite that is timed rightly. This method has not been
demonstrated yet. JpF March 2010.
M1389
M1392
Aloft blades spinning to drive reciprocating multi-membered
sub-tethers for driving groundgen or groundpump. See Loyd's tri-tether
in faired shroud tether. See Faust's
duo-tether reciprocator scheme. See the loop or fan-belt methods.
See also different Dave Santos' Tri-Tether with looping wings
beneath lifter kites in a groundgen scheme. See also the
tri-string of
Lambros Lois for a groundgen. Distinguish
these various methods and provide firm place in classification schemes
for each of them.
M2610
Generator in sky (energy
transport options are several)
No-tether-to-ground jet-stream-involved dual-aircraft EKS AWE
Power beam energy from above. Use differential momentums of two aloft
locations aloft-coupled smartly; one location stays in the jet stream;
the coupled location is out of the jet stream. Massively-smart controls
tap the system for some energy converted to power beams which energy is
sent to receivers on the ground or sea or to active aircraft.

Dale C. Kramer extended with RATs. Free-flight
bi-kited tether.

M2607
Rotor-craft complex: Have conducting tether; use grid electricity to
power the rotor-craft to high altitude winds; shut off the grid powering
that lifted the system; let autorotation occur to drive the rotors using
high altitude wind; have part of the rotation give lift to the system to
sustain positions in the best wind; use the remaining rotation of the
rotors to drive hub or circumferential electric generator; send the made
electricity down the conductive tether to do work locally or in a large
grid. Or use the electricity to pump water into a high reservoir, or to
charge another type of battery. SkyWindPower
company is considering this type of system.
Gen aloft, but no conductive tether: convert gained aloft
electricity to laser; beam the energy to other aircraft or to ground
receivers.
Generate rotations aloft and transmit the rotation via fanBelt or
loops to groundstationed pumps or electric generators or grinders, etc.
Recall the
complex: Dual kite system with no hard tether to ground;
one is drogue generating electricity converted to laser; one is in jet
stream generating electricity converted to laser; lasers send energy to
earth receiver spots with smart tracking; military advances in lasers
bring this more into attention. Operations are smartly robot
controlled. Ground station could be roof top of huge second-purpose
food-production facility, etc. --- public domain. ....

Hybrid methods
UEK in water towed by energy kite
systems; hence water kite and air kite coupled.
Airborne energy kite system towing soil kite generator. Working
tipping boom could be involved also.
TEWP Terrain Enabled Wind Power
Spiders are leaders on this realm; they form webs from terrain and
terrain-based structures. Insects by flight and wind become little
kites as they get caught in webs. The motion is part of the game of
energy exchange; motion warns the spider; the kited insect caught
becomes food converted to energy for the spider.
Rocking arm ---Darin Selby slider with smart use of gravity
in rocking cycle in an aim to capture power in the full rocking cycle.
Rooted windward long arm (perhaps with windward wheel)
Generator could be at root of boom obtaining high mechanical advantage
from the lever arm; and perhaps also generator in axle of windward
wheel, or both) (no reference, but it is close to these matters)
Orthogonal tipping boom (somewhat inclined-windward boom with
counter-mass pendulumed, but connected to windward generator driving
shaft via sprag clutches) (Faust and Santos)M109
