Need ground crew and talent
in Southern California
Hi everyone:
October1, 2009
M335 I'm based in Southern California.
I'm looking for people with trucks, tools, willing hands, computer skills
(recording data and CAD including machine layout and mold design) - any of the
above to help out with setups and logistics, data acquisition, an upcoming film
shoot with Discovery Channel and others. There is no upper limit to
where this
could go (excuse the pun) although I am also pursuing ground-based,
tower-supported solutions.
The locations include my current shop location in Fullerton,
near Disneyland, coastal and especially desert sites such as Palmdale,
Victorville, Hesperia, Tehachapi, Boron, and Palm Springs. It can be a lot of
work but is always interesting and usually fun.
Thanks,

Also, a generous choice of methods for
high-altitude airborne wind-energy capture present to engineers. Two large
categories of methods:
1. Mooring type: Ground (or water) moored
(fixed or mobile)
2. Free-flight dynamic (no tether to
ground or water)
A couple of severe types within the umbrella
categories of LA, MA-, SS- or HA- regards
1. Gen position: position of the generator or
pump: lofted gen or groundstationed gen; and
2. Up duration: whether or not the system is an
"ever-up" or a system that frequently collapses into a non-working phase.
Control further affects design: active
control (robotic or human or combination) or passive control.
Additionally, size or scale matters.
Specific application could strongly
modify design choices.

(57) Abstract: The Kitepower
Generator uses one or more kites that go through
an oscillating cycle of motion creating varying forces on their tether lines.
These
varying forces are converted into rotation, using a crankshaft. The cycle of
motion
may be driven by the inherent kite design or through the action of two or
more tether lines connected to a crankshaft. The pull from the lines is
stronger
when they pull out and weaker when they are being pulled in. The cycle of
motion may involve flapping, swirling, waving, swooping, veering or feathering.
Several kites may be connected or combined into a single composite kite.
Efficiency is higher with three or more lines so that one is always pulling out
strongly. Various techniques keep kites aloft in still or stormy weather..
"The invention uses eight different categories of kite,
each of
which involves a repeated pattern of forces on the lines, caused by
different processes. These categories are:
micro-scale AWE microAWE
microAWECS microLAAWECS microMAAWECS
microSSAWECS microHAAWECS And these
systems in various realms: sport, residential, nomadic recreational,
farm-commercial, farm-utility ... And at mooring
mode: Free-flight (FF), static, mobile.

energy-converter type, service quarter,
application, altitude,
mooring mode, control mode,
budget)

reasonable selections for each dimension; then generate the product ABCDEFGHI
to get the number of product considerations. Focus on one of those 9-D
products and see if you could become enthusiastic about producing a fine-tuned
product.
My first blush selection of size of members of the 9-D AWECS
has these counts (8,2,6,10, 100, 4, 4,3,4) for 8x2x6x10x100x4 x4x3x4 =18 432
000 or about 18 million product points for consideration.
Tweaks for each one of those points would be part of a maker's decision. Plenty
of room for creativity! What do you come up with?

Sample 9-D AWECS: (handy-sized kites, groundstationed
generator, wood-saw, residential, cut logs to flatboards, SS-AWECS, static
mooring using two moored pulleys anchored, active children control left-right

Another 9-D AWECS sample: (giant, ground gen, electric
generator rotary based, utility for grid supply, energize part of Los Angeles,
high altitude, fixed mooring, smart robotic controls, $2 million per year total

Higher-dimension AWECS design tools very well may be useful
to some groups. And many of the dimensions have more choices than hinted
here; e.g. service quarter could be expanded to specific ends--hundreds are
possible, e.g. agricultural, military, advertising, logging, transportation,

Mobile moorings? Ship is
moving, raft is moving down a river, cart is sliding down a mountain incline,
human-holder is running, ocean current is transporting raft, hang glider pilot
is moving through the air, railed cart, etc.
E.g.: Scene: morning with no wind; you are on a river on a raft that is
going down river driven by the current of the river; the motion creates a
relative wind on your kite; you have a TipBoom AWE arrangement and a passive
path-control device aloft.
Free-flight AWE: Another kind of mobile mooring
for an AWECS occurs when the mooring device is wholly flying; this occurs in
several known ways among which are these:
1. When the mooring is a human body and that body is
falling, perhaps even partly flying, as that body is the pilot of a hung hang
glider pilot in the kite-type hang glider where the hang lines are connected to
the upper kite; this kite system uses winds and gravity energies to convert
those in gliding and soaring results. Extend this sort to unmanned
very-smart soaring systems that mine part of lift gains to generate electricity
during the flight; use that electricity to sustain flight or for forming beams
to energize remote receivers. Also see the FFU (free-flight unit
firefight AWE system note).
2. Another flying-mooring AWECS involves a mooring of an upper kite system that
is itself a kite system; the dynamics of the two ends of the tether are
operated to maintain the ends in different wind spaces for a result that keeps
the entire AWECS aloft; part of the dynamics is mined to make electricity
aloft; in one version, some of the electricity is used to generate lasers to
beam to earth receivers or receivers in other aircraft.
Abstract of WO 2009022979 (A2)
The invention relates to a wind-power unit having a kite (1 ) having a line
(3), which is connected with a generator (2) in a ground station. Control means
(4, 7) are arranged to set the position of the kite (1 ) in relation to the
wind (W). By coupling means (5), the generator is (2) connected with an
electric mains (6). According to the invention, the coupling means (5)
comprises an electrical energy converter connected with the stator of the
generator (2). The invention also relates to a method for generating electrical
energy, where the tensile force from a kite is utilized to drive a generator.
The current from the generator is converted and is delivered to the mains.
--------------------------------------------------------------------------------
Data supplied from the esp@cenet database — Worldwide
The utility model relates to a self-powered kite, which belongs to the kite
filed. The self-powered kite is composed of a kite body, a lighting component,
a midget wind driven generator and a control circuit. The midget wind driven
generator is fixed on the kite, a skying hollow space is arranged on the
surface of the kite corresponding to the midget electrical generator, and a
conducting wire is drawn out by the electric power of the midget wind driven
generator and electrically connected with the lighting component on the kite.
Because the midget wind driven generator is used on the kite, the electric
power is increased, the brightness of the lighting component is enhanced, the
electrical battery is cancelled, and the cost is saved.
[ED: This a toyAWECS; the electricity is used aloft in the
kite to power lights on the kite. The generator is on the kite. Extrapolation:
Excess generated electricity might be converted to laser and beamed to receiver
stations on ground or in other aircraft. The drawing looks like they are using
a Dave Santos kitemotor on a tail with a generator in the tail line that holds
the kitemotor; this is my first survey, not comprehensive. Notes are invited. ]

Abstract of
TW 281414 (B)
A shining kite comprises a kite body and a light emitting device located in the
kite body. The light emitting device comprises a micro generator, a fan and a
lamp. The fan and the lamp are connected to two ends of the micro generator
respectively. The micro generator is correspondingly worked by the rotation of
the fan providing electric power and effecting the lamp lighting when the kite
is levitating.
A Traction Kite can sequentially

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.

Editorial quick illustration of Dave's note on the two-anchor stay-aloft
scheme
without need for LTA kytoon:
"After calm, a small (”toy scale”) helium lifter kite can lift a windcatcher
surface to re-launch a big power kite, provided you have automated control OR a
cheap sled kite lifting a high L/D pitching foil to do the pump function,
without special control, at high efficiency. No human needed to
operate ~7/24.
What kite power needs is a business umbrella like, say, WindLift to gather
all the DIY appropriate-tech prototype scale schemes in a collaborative push.

AWECS.

Proof and explication of claims and statements in these talking points
form part of the work being done by researchers, developers, students,
scientists,
engineers, kite labs, AWECS manufacturers, and certification labs.
Sample ground-hugging hard-towered effort:
Vestas
Sample AWECS efforts
So far received:
Heavy turbine blades are replaced by AWECS fabric sails.
Raised generators are replaced with easy-accessed groundstationed
generators and pumps.
Costly transport of large turbine blades is replaced by compact low-cost
transport of fabric sails
Precision hard large towers are replaced by flexible tether lines.
Low-ground-hugging sparse wind sites are replaced with upper-air steadier
and stronger and more prevalent winds in many more places.
Generator maintenance costs are much reduced by having the generator at the
groundstation.
Intermittency of the winds at the ground-hugger hard-towered turbines is
more prevalent than the upper-air winds for AWECS.
Visual pollution by the ground-huggers is high. AWECS can nearly be out of
sight.
Noise.
Disturbance of local boundary-layer winds is emphatically focused by
ground-hugger turbine windplants. Differently the AWECS tap high winds where
the smoothing effects much less disturb local wind at boundary layer.
Large ground-hugging turbines dominate and grab land very strongly.
There are AWECS solutions that may use much less land.
Net cost of energy available for practical work derived from large
ground-hugging wind turbines at best will be heavier than that obtainable by
the best of AWECS.
High production costs of the ground-huggers requires incentives to support
them. The AWECS will so lower costs that incentives will not be required to
install.
As the ground-hugging hard-towered turbine industry begins to morph into
AWECS, there will be opportunities to use what has been learned in the
ground-hugging efforts. The knowledge base on generators, power conversion,
energy storage, interface with grids, negotiating with utilities, communicating
with government, etc. will translate into gains as AWECS becomes the new face
of wind energy.
The large turbine supply chain might morph to supplying kitemotor blades,
kytoon parts, ground anchors, and more.
Can extant towered generators be lowered to the ground and brought into
play for AWECS application?
How to recycle decommissioned large turbine blades?
Could extant towered turbine foundations be used for anchors for AWECS in
place?
Find ways to have extant wind workers of the hard-towered variety be placed
in the new AWECS world.
Give leading information to all workers of the hard-towered industry that
will point to ways for them to tweak their services into the AWECS wind-energy
format. Translation may be easier than remote replacement.
Game: Give $100 USD to each of two engineers. One engineer does his or her
best to generate useful electricity from wind via ground-hugging methods during
the course of a month. The other engineer does his or her best to generate
useful electricity from wind via an AWECS system during the course of a month.
Neglect wages for the engineer. Have no other workers involved. Carefully
observe the manufacturer and working systems. Measure carefully the energy
production rates and challenges.
Where to site towered wind turbines is difficult; siting AWECS is very much
an easier task.
Ground-hugging towered turbines have a tight operating range; AWECS have a
broad operating range.
Site testing is less costly in AWECS. The Hard-towered turbine siting costs
are tremendous.
Ever-up AWECS will permit use closer to energy consumption points.
Turbine wind shadow in the nearly 2-D ground-hugging hard-towered wind
farms causes land-use spread, whereas the 3-D space in AWECS compresses
land-use needs.
Ground-hugging hard-towered can be viewed as approximating a
two-dimensional mining operation; AWECS differently can be viewed as a thick
three-dimensional mining operation where the energy-density over a
land-line is far greater than the energy density in the ground-hugging realm.

mix that includes the efficient airborne-derived energy.

More land owners may play when airborne wind power is involved.
Wind energy manufacturers will do well to plan for the airborne wind energy
needs.
Wind component suppliers may begin adding AWECS components to their
profile.
Learning from the low-wind 2-D hard-towered dominant habit as AWE evolves?
Digest all that is happening in wind power; then see how AWE may emerge from
the flow.
The main photo used at EWEA web shows the turbulence shadow of hard-towered
turbines; the photo gives a strong press toward the 2-D-ness of ground-hugging
fixed-base hard-towered windpower.
Ground-hugging hard-towered turbine farms affect local downwind weather,
agriculture, wind, temperature, ground-moisture content, turbulence, windspeed,
agricultural interests, recreational interests, and more. How does all of that
compare with MA-AWE? (mid-altitude AWE)? HA-AWE?
Wind energy conversion has been occurring
airborne for nearly 4000 years!
What say you? Yes, the dancing and tugging kite lines show the
obvious mechanical energy derived from the kites' interaction with the winds of
old. That dancing and tugging kite line can be levered by the TippingBoom
or TipB--and by other means too--in order to bring that mechanical energy into
works: grinding, pumping, exercising arms and leg, rotating the parts of
an electrical generator, transporting vehicles, etc. Airborne wind-energy
conversion systems have a little brother where the tether became short and
stiff to form the hard-towered wind-energy conversion systems operating in slow
winds in constrained sites. The tensional-towered tethered airborne kite
systems tap high winds with less site costs. The ever-up AWECS will win the day
for small and large installations. There are several types of ever-ups: HTA,
LTA,
TEWP, {FFU (free-flight unit), and FFB (free-flight binary).

Effects of windpower systems on wind patterns and climate?
How do hard-towered windpower turbines in windfarms alter local wind
patterns and climate?
How would AWE windfarms alter local wind patterns and climate?
Could non-jet-stream AWE supply all energy needs of humans?
How would a massive AWE windfarm set in a jet stream alter wind and
climate?
Could MA-AWE (middle-altitude AWE) be more friendly on local climate than
ground-hugging hard towers?
Will seaAWE be wholly acceptable as to weather effects?
What could be the effect of have the upper surfaces of kites in AWECS be
solar reflective so help send some of the sun's radiation packing back out to
space in order to keep the earth a bit cooler?
If we learn enough, perhaps MA-AWE could be doubly used to cause
some local climate changes that are wanted.
What % of available wind would supply the our energy need? Ask
of
Cristina Archer and Ken Caldeira:“If you tapped into 1 percent of
the power in high-altitude winds, that would be enough to continuously power
all civilization,”
Some authors have brought up the Butterfly Effect
from chaos theory
to question what might occur when mining wind for its energy.
Every energy sourcing will have costs and effects. Comparing results is
part of the large process of choosing. When we obtain energy from AWECS to
reduce getting energy from coal, oil, or natural gas, then a trade of effects
occurs; how will the trade go?
KiteLab Disclosure; yet another scandalous AWE reality-
Tropopausal Stagnation Zones
Here's the true science- High Altitude Wind Power is a technical
myth. It is the earth's rotational/flywheel energy that counts & global wind is
mostly air dragging along at a slower speed. Wind actually flows backwards
relative to the ground . The jet streams are worst of all & are more aptly
named "Tropopausal Stagnation Zones" .
The secret to AWE is to tether the rapidly moving earth to rags
dipped into the most stagnant air.

Airborne Wind
Energy for Nomads
Dear Dr. Ismail Iro,
Your piece on Nomadic Education and Education for Nomadic Fulani make an
interesting read.
http://www.gamji.com/fulani7.htm
I am the African Regional Co-coordinator for the Airborne Wind Energy Industry
Association (AWEIA) and a director of the KiteLab Group. The
KiteLab Group
headed by David Santos is an R&D firm in the field of Energy Kite Systems.
http://www.energykitesystems.net
Given the potential applications of Energy Kite Systems in the Nomadic World
ranging from transportation, electricity generation, water-pumping and plain
fun, you will agree with me that the Airborne Wind Energy Conversion Systems
should interest relevant governments National & States, communities and other
stake-holders in the migrants world which includes all who depend on the meat
from the pastoral nomads' cattle.
I will be delighted if you would please link me with the National Commission
for Nomadic Education in Nigeria for a possible partnership for the development
of appropriate energy kite systems for the Mobile Schools that would save much
on fuel costs and is safer given risks of transporting petrol for generator
running.
Thank you for your kind favourable disposition.
Sincere regards.

Nice clear
distinction, Pierre
Benhaïem:linearAWE and
cyclicAWE. Great. Indeed
there are many linear AWECS methods and many oscillatory AWECS methods.
Linear via traction and tug; linear via reel-in-and-out method.
Cyclic: TipBoom, RockerArm, Eights galore, OrthoKiteBunch, etc.
And there seems to by a kind of combine that is linear and cyclic with
pulsations linearly on tether.
Pierre
Benhaïem of France, as a non-enterprise contributing national team
reporting representative in AWEIA, officially entered his application for
AWEIA membership as a founding member.
In agreement with the founding circle he envisions synergy under his following
expressions:
Possible actions:
-develop my projects.
-enter ideas for a classification of AWE.
-report related information in France.
-have contacts with eventual economic, politic, or industrial actors
to raise an interest for AWE in France.

[ED: urban wind energy, urbanWE, urban AWE, urbanAWE,
urban wind power, urbanWP, TEWP, TEAWECS.
Distinguish between airborne wind energy conversion systems and the various
species of terrain-enabled wind energy conversion systems. Some TEWP are
airborne devices that sustain themselves; some are airborne at calm and also
upon wind reaction; some become airborne under wind while resting on ground in
calm; etc.]
A subject extending TEWP subject.
What are possibilities for AWE as UWE?
Here is the first installed UWE in France (Calais), byWindWall,
Dutch company. The structure of this horizontal axis of type Darrieus is next
toDarrieus
between buildings which the great difference is no specific supports
at the two ends of axis (supports are houses themselves), and its place between
two houses (or mounts, as shown on TEWP topic).
[ED: The title is very interesting. Of course nonAWE solutions in
urbanWP have niche-application importance that is being broadly developed.
However, there remains the question of
urbanAWECS
where the systems are sustained by interaction with the air via buoyancy or
aerodynamics with wind or a combination of both. There are innovations
occurring in urbanWP in nonAWE as well as urbanAWE. Of course, during the
development of AWE in any environment, there well may be hybrid schemes that
remain interesting to AWE developers and nonAWE wind power developers. It is
neat that centers of innovation are occurring in both nonAWE and AWE.
EnergyKiteSystems has a core focus on kite- and kytoon-involved wind energy
conversion systems; this focus is advantaged by studying the boundaries of the
airborne focus. That is, keeping the airborne focus while looking at
near-AWE systems has proven to be beneficial to the AWE aims. For instance,
consider the Darrieus beads of Darin Selby that could be kited in several ways
fully airborne; consider the Selsam multi-rotors in their non-AWE formats and
their airborne formats; consider the Dan Parker SpiralAirfoil in both the
non-AWE and the AWE schemes. Lofting by kite systems all kinds of turbines are
the eye of many AWECS developers. ]
The
drawing posted is meant as an invitation for others to send in
fan-belted arrangements for airborning working tri-blades, di-blades,
and uni-blades for pumping fluids or generating electricity with generator on
the ground. All those hard-towered ground-hugging blades might be lofted sky
high via tensional schemes. Small or large blades. Consider both
upwind and downwind settings. Consider singlie blade or uni-blade. Consider
double-blade, triple blade. Consider inflated blades under the airbeam tech
including tensairity embeddings.

Many terms have
yet fuzzy definitions to be sharpened in time.
Have a go at
the wiki for paravane that has been warmed by at least two of us.
2. energy-production systems that use both water
kites and air kites in some cooperative arrangement; this would be a hybrid
AWECS that involves water kiting and air kiting.
3. AWECS that are used in combination with water
turbines which turbines are not kites.
4. AWECS: onshoreAWE or offshoreAWE (SeaAWE) or
systems that at once have parts onshore and offshore.
Some waterKite items and AWE
Kite pulls hydro-turbined barge. The hydro turbines make electricity.
Perhaps the barge is also a surface for solar-cells. Perhaps the barge uses the
electricity to make hydrogen and perhaps compress that hydrogen to be delivered
at various ports or at-sea structures or ships.
AWECS pumps water into a raised reservoir or tank or pond; the water is let
out to drive water turbines.
AirKite drags waterKite; the dynamics are smartly controlled to effect both
transport and some mined electricity for use in the traveling system.
KitVes approaches a hybrid of this.
Cable anchored in sea at two points provides a path for a hydro-turbine
driven left and right by airKite.
AirKite AWECS at sea pumps air into deep-sea bladder to store energy;
release of the compressed air drives electricity-generating turbines.
Traction kite pulls hydrofoil with varied hulls or no hull for transport.
Air-kite driven boats and ships dip water-turbines to generate
electricity.
The practice of bi-fluid two-kite systems (air and water) provide some
practice for far-term dual-kite AWECS having no groundstation.
Kite fishing has potential of saving the use of fuels.
Some confusions are possible; say "water-kite" to many water-using groups
and they will think power kite that operates in the air.
The large use of air kites in reducing use of other fuels in
freighter-tugging are free to "fly" water kites for various uses: turbine-laden
for energy production, mine clearing, cable lowering, underwater camera
placement, etc.
Waterborne devices (hulls, boats, waterChute, waterDrogue, raft) in flow
with the water stream; tether an airKite to the waterborne object; have lofted
air turbines in the airKite system that generate electricity.
Just putting out here:
Chico, CA, sponsored a large 2009 Yo-Yo championships. The Yo-yo term has

As you design AWECS, consider
these binary ways.
And then in your joy, consider adding a note toward these binary ways.

Yes, I see. He even took a hit at "dipping boom" which is close to my "tipping
boom" that he and I collaborated on. He is positioning and practicing for being
clear. He is racing ahead for specific practical achievement goals. He is
aware of vast nich variations of methods, but is pressing for efficient
watts/kilogram and safety for large systems practiced first in handy sizes.
Different goals, different parameters, different settings, meeting different
requirements, fulfilling different qualities, etc. bring a vast opportunity for
alternative solutions. The AWE community has yet to have a handsome
classification system for method options. It is not time to toss any method
aside.
Beloved Pastor sir,
Permit me some of your time to drag you for at least a peep into a new world
God just brought me into and has so swiftly lifted me up (I did share with you
briefly) therein that I will really appreciate supportive prayers of all I know
for His divine sustenance and further lift here.
AWE is an acronym for Airborne Wind Energy. Airborne Wind Energy Technology
is just about market ready and is in reality an extension of Wind Energy
Conversion Systems from the old hard Towers for WindMills to the more powerful
and more consistent winds higher up by means of 'Kites' or other unmanned
aerial vehicles. Kites can now power/tug sea vessels, pump water, and generate
electricity at costs possibly cheaper than fossil fuels.
Yours truly is the pioneer African Continental Regional Coordinator for
AWEIA.
A man named Dave Santos noticed my efforts in a mutual internet based
organization we both belonged and introduced me to AWE; and he has also asked
me to come on board as a Director in his
KiteLab Group (under formation). KiteLab is a leading R&D firm in
Energy Kite Systems.
[ED: The airborne division might historically
be the first
or one of the first hard-towered ground-hugging wind power firms
to open an airborne division for their turbines.
This leadership action models a key reformation possible for many hard-towered
firms.
We have invited Vestas
to do similarly.]
Dan,
I just noticed that your leadership forms an historical
crossing that spearheads reformation of hard-towered ground-hugging firms into
airborne wind energy conversion systems. Actual first is a
fuzzy question; I do not have clear what has happened in the Netherlands and
Italy, etc. Perhaps an AWECS player is launching from a hard-towered firm;
full historical view is not yet available to me. JoeF

Scene: Small
thirsty dam where there is just some water, but not sufficient to continuously
operate water-through let for hydro power. What to do? Drop the water
through the hydro turbine and generate electricity, but catch the water just
below the dam and pump that water back up into the reservoir via AWECS. The
reservoir keeps its water and acts as a rectifying smoothing battery to give
electricity whether the wind is blowing or not. Notice that there might be some
options to consider. The AWECS pumping of water involves mechanics different
from direct electrical generation. Using the AWECS during wind to drive the
generator incorporated with the dam's hydro turbines instead of dropping water
to the below-dam catch would be a consideration.
JF
Note- It may make sense to drive the hydro-generators in "dry mode" by kite,
saving the water (without pumping it) when wind blows. DS.
Related with these matters is a closed-water system where a flat region of land
allows the digging of a hole; use the soil to form an above-ground reservoir
which gives head to held water. Drop the water through a hydro-generator into
the dug hole. Use AWECS to pump the water out of the hole water back into the
above-ground reservoir. Line both reservoir and dug hole with impervious
material to stop soil-loss of water; float evaporation stoppers on both water
holds. The hydro-turbine provides electricity night and day as needed whether
or not the wind blows. For the minimal system there is a water pump and an
electrical generator. At some times, it might be advantageous to dry-run the
electric generator by the airborne prime mover. JF
Use kite energy or kitricity to condense water from airs (ambient air, air
over damp soils, airs humidified with plant pruning, etc.). There are yet
places on earth where this application might be important.
Following Domina Jalbert's lead of breathing water as air for
kiting, see the rapid development that can happen immediately for air and water
using kiting AWE methods. Both hydro side-planers and inverted AWE
underwater paravane schemes need no breakthroughs to obtain gigawatt
operations. Attention national decision makers!

WindLift's Robert Creighton
has been added to the speaker list at the Nov. 5-6 conference in Chico, CA.
See his summary.
Test one variDrogue oscillator of 1 meter diameter for energy extraction
from the wind.
Report results. Describe how you oscillated the variDrogue from
full drag to minimum drag. Then add behind the first variDrogue another
variDrogue at your chosen separated distance on the same axial varying control
line. Test and report extracted energy of the two variDrogue arrangements.
Then have a chain of three variDrogues with separation you choose. Test the triple.
Analyze the experience. Loft the three tests using a major stable lifter
kite and run the variDrogue drive line through a pulley to a groundstationed
pump or electric generator. Photos? Measuring? Analysis?
Photos and drawings may be entered via direct e-mail for publication.
Separation distance will matter.
In typed symbols:

A fabric variDrogue might be the least expensive type of variDrogue, but
others are welcome. Some might even respect a traditional bladed thin-winged
rotor with variable pitch as an instance of a variDrogue.
Assume a fixed ground anchor for a kite at sea level on earth. Assume smooth
wind stream. Assume a tether length of 100 meters. What is the maximum apparent
airspeed that may be experienced at a given kite's wing? Assume ambient
wind to be 100 mph for one case. Then consider ambient wind to be 200 mph.
Then consider ambient wind of 300 mph.

Note from member Pierre Benhaïem from France, AWEIA team reporting rep
for France:
By Pierre Benhaïem:
I am happy to join the following notes and the above image.
AWE traction kites like those used in kitesurfing or KiteShip boat traction
or SkySails cargo-ship tugging do work perfectly. Rotation
for AWE kite generators raises different problems with identical
aerodynamic features from the kites.
From linear AWE: good transmission between
tether and generator, but dispersed swept area. So its economical interest
is limited because of the too important ratio used aerial space/power.
From cyclic AWE with kites:
low ratio used ground and aerial space/power, but problems
of transmission: the useful tangential force (which creates torque) is
limited and there are important axial and radial forces (which do not
creates torque, but damages to the structure).
Mechanical characteristics are the base of OrthoKite system studying.
Double lever systems' theoreticals allow use of the complete flight window,
left and right. However, on known devices left-and-right levers like
Fig.1b on Payne's 1975 shown patent,
simultaneously are pulled, that to assure left and right motion. So radial
force is high, since transmission is + - 180°: Radial
force is necessary to put the device in oscillating power motion: so
tangential force is low. The benefit of lever
demultiplication* is weak
(perhaps it is the reason why there are few descriptions of this point).
OrthoKite system transmission is about 90°, so radial force is low, and
tangential force is high.
Axial force is a common problem for all vertical axis. It is the reason
why a OrthoKite variant describes jacks under the swiveling tray for an
adapted oblique axis. With such a device, trajectories of kites are
light curves on a vertical plan (instead horizontal trajectories).
On OrthoKite system
demultiplication*is
such that the length of its radius corresponds to power/radians/second, and
is dependent on the ratio L/D of the kites.
The first easy experiment (without kite) with a salad spinner with a
scotched ruler: Pull on the tether on one end = high torque. Pull on tether
on two ends = high radial force (high traction, low torque).
The next experiment with a kite: An OrthoKite variant with a wagon putting
in motion the two lines of the kite--one end to the other end of the double
lever.
Furthering this, here are some steps: A complete prototype with a storing
device smoothing generator production, sensors, automation. The storing
device is an hydraulic installation with hydraulic actuating,
hydro-pneumatic accumulator, hydraulic motor. For this step, at least
a funded firm is necessary.
I would be happy these matters are scientifically developed and points made
precise on tangential, axial, radial forces. This furthering process is one
key for AWE projects.
[* ED: Usage for the offered
"demultiplication"
is requested. :"démultiplication du levier"
reduction? multiplication? Pierre
offered: "démultiplication du levier" good sense of
translate is magnitude of the torque of the lever arm.
Also, we have linearAWE, cyclicAWE.
Corrections on the text are still invited.
From top of de-commissioned tri-blade towers have AWECS line go out the top
of tower. Line would go to ground through interior of the tower to
generator on the ground level for better maintenance access
Cable between two de-commissioned tri-blade towers; use that cable as a way
for a going generator rider that is drive by a traction kite controlled for
the left-to-right pathing.
Cable AWECS between two de-commissioned tri-blade towers for playing an
ever-up AWECS that is yet HTA type; use the Santos ever-up
energy-in-at-calm method, if appropriate.
Raise tower that is a actually a ballasted tipping boom driving by kites;
the oscillation drives a sprag clutch gen.
Have two towers on a small residential property. String a kite with two
lines between the two towers; have the lines go through the interior of the
towers to a sprag clutched generator
On a 100 m tower: Hang a kite that droops in full calm to be 10 m from the
ground. At wind: The kite self-starts and triggers boom-sway driven
generator; boom sway is driven by kite sweeps via smart-reading sensors and
fly program.

As AWE grows, professional management of supply chain matters will
be needed; supply-chain issues will arrive and need resolution. Most extant
professionals working in the ground-hugging wind power sector will be able
transfer their attention to AWECS. Because AWECS promises more site options,
there is the possibility of AWE finally producing much more total energy than
the ground huggers. JoeF]

Self-re-launch strategies? AWE kites systems that are not ever-ups
may be self-launched in various ways. Welcomed are your found strategies. See
elsewhere for growing the very different ever-up methods (EU-AWECS).
Reel in the tether and have a kite-parking scheme that is robotize; when
sensors note adequate wind, start groundstation blower to inflate and raise
the kite to a starting format; let the wind do the rest in coordination with
programmed winch.
Have a field space that allows un-snaggy relaxation of the full kite and
tether. Have the kite shape be such that it catches breeze and rises on its
own.
Have a small He or H2 balloon that teases the calmed kite to
catch first breeze. (Someone might find a niche application for a hot-air or
solar balloon for self re-launching assisting of an AWE kite)
Have kite land leeward of a high cable. The becalmed kite hangs leeward
of the cable and remains dangling until the breeze returns. This is mostly
for where wind is in one directions (tight constraint!).

Ribbon rotor driven by a hub which hub is driven by a kite-derived
energy. Rotor-tip mass and some strategic stiffness enhances the ribbon's
performance.
Rotating ribbon bow kite. This is a Magnus-effect
kite. Some mining of energy can occur for secondary work SkyBow

hydro water movement from high to low to high again with good timing in
conjunction with renewable intermittent resources. Small versions have
been simply called water-battery in the AWECS community. See the small
urban flat region instance of such technology with AWECS serving even small
home away from rivers or away from oceans; a closed set of water holds set at
distinct heads provides a "water-battery" to hold AWECS-gained energy in upper
water-hold; drop water through a small hydro generator to lower water-hold;
pump the water back up with AWECS. This mimics natural processes in preamble to
traditional dam hydro power where air-carried water rains and fills dam;
drop water to get hydroelectric power; sun gets the water again and drops the
cloud squeeze back to the dam.
From the
SkySails calculation page: "The
SkySails-System can only be used when the vessel is underway."
And in their calculations they take 210 days as a working figure for
"underway." That leaves 155 days with non-working kite. What
if they figured a neat way to use the kite during those 155 days (or a good
portion of that time) by well-anchoring ship and flying the kite at a bit
higher altitude in reel-out-reel-in dynamic pitch-control to generate
electricity stored at port or onboard or both directly or as a conversion into
compressed hydrogen. Then sell or use that energy. This might make the SkySails
system even more valuable for the ship industry. Just a thought.

for AWECS. Indeed, some are aiming some AWECS for mining the energy in
hurricanes.

Airborne-Driven Scalable Encased-Bi-tank Hydroelectric Power
Method can be emboldened at most AWE scales
In one application: Whenever water is dropped from a tank for drinking,
washing, irrigating, etc. hydro-electric generation might be in-line in front
of the final catch. The banked water head is maintained by influx from wind
energy, perhaps AWECS.
The closed-cycle versions may be at many scales. A nomadic installment
might be a high tank and a low tank; charge the high tank via AWECS from
initial rain, creek, ground, river, ocean waters. Then upon drop of water
have in-line hydro-electric generator. Aft of the electric generation either
use the water for several end uses or have the water ponded or tanked ready
for the kite systems to pump back into the high tank. Consider at wind using
the kite system for direct electric production solely or in combination with
filling the upper tank.
The lower tank is exemplified in large scale by the forwarding of the
company AquaBank where
the lower tank is far underground; their upper tank is ambient river. But
upper tanks may take many forms: pond, bottle, ocean, creek, reservoir, truck
tank, local water tower, etc.
