residentialAWE version:

In notes I placed a drawing of a rural village-scale version of water storing. Suppose there is flat land with little water. Dig a hole. Use dug soil to build up a water hold. Now we have an upper hold and a lower hold. Line the holds with non-seep rubberized fabric or sealed concrete (bring in best comments by soil/water-hold engineers). Fill the upper hold with water to prime. Top the water with non-evaporation material. Set up kite pumping to pump water out of the lower hold.
Drop the water from upper hold to lower hold but with in-line hydro-generator. When when is blowing and kite pump is working, pump water to upper hold. No water tower, no buried tanks. This would be a minimum.

sportAWE in this realm could be to compete on a sport field with pumping water from a low tank to a high tank using a kite system. Limit the total weight of all parts used to get some innovative use of materials. Or other balancing rules. Prizes.

Methods in this direction grow to Aquabank, the mines and lakes DaveS mentioned.

Tidal dams catch the high tide and drop the water to generate electricity.

AWECS can pump water directly or indirectly (after generating electricity: use that electricity to pump).

toyAWE could pump water up a kite line and let the water spray out over recreational areas.

commercialAWE could pump water up a kite line and let the water spray out over crops, if such is found advantageous.

There is in the literature the pumping by kites of air into anchored bladders deep in water. Then release the air to drive turbines to make electricity when needed.

Fence of soil bags hung with line through pulley; lines to generators. AWECS crank gears to raise soil bags. Dropping bags generate electricity to light the fence, electrify fence, power village, etc.

Large air bladder beneath large soil hold. Crank via AWECS air into air bladder to raise the soil. The pressurized air could be released to inflate things, drive working tools, generate electricity, etc.

Let's Get Wind Power Off the Ground

Send your online note now

  • It seems that research over the growth of the industry is not yet being done by many authors. Only about 15% of known AWE companies are mentioned in the article.

  • The article notes Makani's use of a hang glider.

  • The article notes Makani's use of a "rigid-winged device" without any clear description.

  • The timelines seem to neglect that there already has been proven systems accomplished by such as KiteLab of TU, KiteLab of Ilwaco, WA;  these not mentioned.

  • The author apparently has not seen the front page of EnergyKiteSystems.net   as resource. This has me wonder about the neutrality of the article.

  • The highly successful already-being-applied AWECS in the shipping industry did not get a mention, yet huge horsepower is being captured from kite systems ALREADY.

Send your online note now

So far:

  • To avoid being responsible for injuries from the public's use of products, report what you know about the safety of AWECS systems; such information for safety should break the veil of proprietary stealth actions. 
     

  • When your AWECS company knows about certain safety-critical safety modes, then publish that information. Help keep the industry strong by such practice.
     

  • AWEIA is proposing that any AWE worker knowing something that can increase the safety of AWECS will publish such.   Cooperation on matters affecting the safety of AWECS seems to be a given.
     

  • Our industry in all scales will have the responsibility to be truthful in advertising, especially in disclosing safety-critical aspects of an AWECS.  This is a doable.

Comment on news release, so far:

  • Super-great conference. Cristina Archer extended the Innovator of the Year at the the college.  And she thanked P.J. Shepard for the idea of the Conference. Working committee started for forming suggestions to attendees for a inclusion airborne wind energy international association destined to be very inclusive as regards scales. Saul Griffith pointed strongly the changes to "become" an industry, which we are not yet. Faust present the AWE Triangle of 10 scales with a very neat circling of his kite life from the 1960s two-kite free-flight dynamic soaring system with a lateral revelation that in recent decade Wayne German and  Dale C. Kramer have been visiting the FF-Soar method; Faust extended the FF-Soar to the FF-AWECS as the 10th scale of AWECS.   Wonderful showing by Italy, Germany, Ireland, USA,     .... many more stories and notes will be being posted by attendees, .... fun and serious.   Fresh new meetings by formerly digital friends were made. Doug Selsam put on two days of demonstrations. Local papers featured the conference. San Francisco Chronicle front paged the event.     The robust variety of methods were appreciated by attendees, but the world still just sees a blur of having a strig up to something in the air.

3Nov2009 Underwater kites (paravanes):
Tidal power from slow currents with kite usage
Minesto, a Swedish and UK based company

"Deep Green" is term for the tidal paravane project.

"The second stage uses a generator
to convert kinetic energy into electrical power.

The net result is increased power from a smaller package. The planned normal full size weighs only 7 tons excluding anchoring which gives an energetic payback time of 3 weeks, compared to 8 months for onshore wind."

Related:

Notes:

  • Kite tech of air kites will play to advance paravane tech. Fertile ideas can play the other way also.

  • Hybrid air and water systems are part of AWECS. E.g., the air kite towing of a barge that is saturated with water turbines.

  • v

  • Sweeps in the low-velocity current multiplies the energy-harvesting just like we do in air kiting.
     "The method increases the flow velocity into the turbine by 10 times, compared to the actual stream velocity."

7Nov2009 What happened and will happen because of the talks, meetings, and networking that occurred in the last two days at the Chico-Oroville conference?                             

So far:

  • Annual Wayne German Award was extended by Wayne German to Dave Culp and Dave Santos.
  • Saul Griffith encourage new starts to form collaborative agreements in a business-like manner.
  • Cristina Archer received her university's Innovator of the Year award.
  • The AWE Triangle of Ten AWE scales was presented where the tenth scale was FF-AWE.
  • Wayne German proposed  tethered wings of 1000 m length set spanwise vertically and in sets.
  • A faction of attendees wants kite energy systems to be used only for peaceful purposes; others accepted that there are some non-offensive military uses of kite energy systems.
  • A working committee was formed to propose to attendees eventually a first name and set of bylaws, etc. of a non-profit association that would represent the interests of tethered wind power internationally. Joe Faust was asked about his pioneering steps toward the same target; he expressed joy of the progress and committed to cease AWEIA and EnergyKiteSystems while giving full support to the processing started at the conference. So, as of November 6th, the two sites will be become passkeyed and out of the public area to give full public space to the new process.

11Nov2009 Long fence orthogonal to wind is proposed.  Fence is an energy-generating fence. Beads of contra-rotating wings on cables form a fence, perhaps sloping fence.  Then the long fence is with a second use: slope soar to point A to point B, perhaps commuting to town or work. In water: Long floating snake provides wave energy, solar energy conversion surface, and slope lift for long travels by free-flight hang glider and paraglider manned or unmanned kites or soaring load-carrying kites. Some such energy fences will go hundreds of miles.

A cousin proposal is a long cable. Loaded man or unmanned kites will tether slidingly along the cable while kite-sailing long distances to save on use of coal and oil. Fly long distances oblique to the winds. Loads could be people, ore, water, animals, goods, etc.

Africa: AWE Training Camps

"Kite-Pilot Vocational School"

The regional AWEIA rep for Africa has spawned the concept of
AWE Training Camps where people can train to handle AWECS.

So far:

  • KiteLab Group (KG)  AWE mentor DaveS with our Africa regional AWEIA rep John Oyebanji are forming the outlines of what could be a movement throughout the world.  Engineers at AWE new starts, technicians who will be handling fielded AWECS, operators, managers, extra-hands, etc. could do well to become skilled with safe arts and skills involved in AWECS.  Hands-on building and flying sport-sized AWECS can be a good preamble to activity in nomadicAWE, residentialAWE, and even commercialAWE and utilityAWE.

Reaping the wind : how mechanical wizards, visionaries, and profiteers helped shape our energy future

Author: Peter Asmus
Publisher: Washington, DC [u.a.]: Island Press, c 2001.
Edition/Format: Book : English View all editions and formats

The book does not have the word "tether" in it. The word "kite" was used once only as an aside to measure winds on its page 84.

19Nov2009 VAWT or vertical axis really can be more properly called "rotating axis normal  to stream." For example, the VAWT of Darrieus eggbeater could be held between two terrain points in a manner that the rotating axis is even or oblique to the horizon, so long as the long rotating axis is blunt to the stream.   The common "vertical" is unnecessary; such arrived by simply choosing the one angle for the axis to be zenithal relative to earth center.

20Nov2009  1. Cabled tethered travel using serial small blimps.   The travel cable is kept aloft by small kytooned blimps that recharge aloft via splitting atmospheric water to hydrogen and released oxygen. Cable rider sails along the cable, crawls along the cable, slides down the downside of gravity catenary segments, PV-driven cable crawling.   Wayne German of Tethered Aviation is forwarding a local system.   Yet KiteLab of Ilwaco, WA and I have been discussing even world-around small-blimp use for tethered cable-travel ...from node to node.     A second use of small blimp in this sector could bring maintenance workers to parts of the cable, carry a passenger to the cableway, offload a person or goods from the cableway.  SkyCableWay.    

2. Small blimp AWECS.   There are many ways small blimps could play in the wind-energy conversion world.  Airborne wind-energy conversion systems (AWECS) may be used as the primary actor or as a lifter for secondary actor where action wings lifted remain primary actors to generate electricity either aloft or at groundstation.  Ever-up small blimps kytoon shaped that could recharge aloft from splitting airwater could be in an AWECS generating electricity night and day all year.  Second uses of the same system: surveillance, real-time vision, antenna, observation deck, vacation hut, launch pad for hang gliders, and more.

So far,

  • Toys grow up.
  • Gearbox changing direction of drive.
  • Kinetic energy of wind by one or more rotors is mined for driving the lifting propeller.
  • Instruction just missed mining some of the drive for conversion to electricity or driving loop to ground generator. That is fine; we can do that.

22Nov2009    Q1. Are there any AWECS installed and working right now in November 2009 to save on coal and oil? 

A1.  Emphatically Yes.    The many ocean-going boats and ships that are using kite tug are using AWECS systems. The kites are converting the kinetic energy of the wind into a pull on ropes that in turn pull the boats and ships through the water; this saves on coal and oil.     Dave Culp noted at conference recently and in group AWE that the world could just about meet its 20% wind energy portion of energy consumption without using a single electric generator in AWECS, but by equipping appropriately the boats of the world with kite tug systems.

Q2. Are there any electricity-producing AWECS installed and working daily ordinarily in the world.

A2. Maybe.  News is not in on any at this desk.  We are aiming to get some such situation going. Test durations have occurred for some hours; please report your durations and gains with defined systems.  Describe your AWECS; tell aloft duration and amount of electricity produced; describe what happened to the electricity generated.

22Nov2009 Regularly I battle DS as I support AWECS that are aerostat based; he prefers non-aerostat progress in AWE.    My pet reach has to do with getting everUpAWECS with aloft self-recharge of hydrogen-based aerostat.   The ambient atmospheric water would be collected and split to recharge bladders with hydrogen; the energy for the splitting would come from wind or PV or both.       

Also, one aerostat pet is the simple non-kytoon spherical LTA aerostat that holds a lofty tethered kite in train along with a below-aerostat line Santos Sputnik wing that will work  large jiggles in the main tether; at wind the upper kite lifts to sustain while lower Sputnik wing works; the simple aerostat keeps all up in case of full calm.  Send your online note now on this topic!

Their page title:
The Parafoil Kite
An Engine For Many Extreme Sports

[Ed:  Easily the simple kite (parts of the engine: sail, bridle, tether, mooring, control system, mode of operation) is a rotary engine rotating about its mooring point, sometimes one way, sometimes another way ... all the while extracting energy from the wind's kinetic energy to form mechanical energy available to perform work; hence a flying kite is a tethered turbine. Send your online note on "kite types" now on this topic!]

So far:

  • M559 thread
  • Besides the simple kite being a rotary engine that is a tethered turbine, kite systems can have a second level of being involved with turbines: the kite body sometimes is a turbine, sometimes the kite body can hold sub-element turbines, sometimes the whole kite system can hang sub-elements that are wind turbines.   And further, some schemes have the kite line's direction and tension work ground levers that turn ground turbines.
  • Dave Culp  of KiteShip triggers clarity. 
  •  
  • It is seen clearly by some that the elemental kite flying (with its necessary parts of airfoil, bridle, tether, mooring, control system) in air or under water is itself a rotary engine, a true airborne (or waterborne) tethered turbine in its totality; that engineering text won't best sell AWECS, Lang purports. From that technical kite-system base,  tertiary turbines may be added or not in various ways aloft, inline, or on ground as particular systems develop. 
      
               However, just what terms to use in what setting? 
    Who is hearing what?
    Text is needed for various involved communities: Fit the audience's needs. What of the ten scales will the terms be used (micro, mini, toy, sport, nomadic, residential, commercial, utility, national, free-flight), as scale space will tend to alter some terms. The physicist working in micro flows in the medical community will use text different from the counter salesperson selling an AWECS at a toy-sport kite shoppe. The boat person using a trolling paravane for doing special tasks will have his or her language. The utilityAWE administrator managing hundreds of field AWECS workers will have a language fit to the purpose. Etc.
     
    • Deep engineering designers, original-AWECS manufacturers
    • Buyers
    • Users
    • Operators, repairers, technicians, constructors, installers
    • Investors
    • Sellers, dealers, promoters
    • Patent examiners, inspectors, and lawyers, and the patentees
    • Lawyers, judges, legals, insurance-company litigators
    • Airspace-control community
    • Public newspaper editor, magazine editors, headline wordsmiths
    • Educators, authors, clarity-seeking students

    These communities need terms that fit their flow, culture, language modes. That a simple kite is itself for a design engineer may be be seen as a flying tethered rotary engine capturing wind's kinetic energy and converting it immediately to mechanical energy to be then further converted or not to other uses ....is not fit text for the buyer-investor-seller community. The struggle to get terms has some positive side effects affecting even the deep design. The rich discussion is gifting insights.  Out of the cloud of terms will come assets that the emerging industry will use to carry out its effort. Successful systems well sold and effectively served will be able to set the temperature  language in the open public market.  News releases from the AWE community will help to guide the text in some of the communities above listed; but newspaper headline designers will still do their special take on things.

    Pierre Benhaïem urges getting to some "first name" or front name to represent to the public our emerging industry. For behind-the-veil secondary name, he likes for the in-the-know-designing-manufacturing community the inclusionary AWECS (airborne wind energy conversion systems).   But a public buzz term is sought for fronting the industry-- one that will attract investors and encourage buyers to make commitment. What could such a term be?

23Nov2009 Jet-stream sailors  are getting ready for adventures across continents. They will be using two unpowered tether-coupled kites; the kites will appear in various forms; one may look like a sailplane; the other might look like a paraglider; but each designer will modify how his or her kites appear to the general public. Some will have a human in both kites. Some will have a human in just one of the two coupled kites; prototypes might be unmanned radio-controlled while the skill of maintaining the dynamic soaring machine aloft. 

The entire machine is a free-flight wind-energy conversion systems or dynamic-soaring bi-kite aircraft operating in a fresh new way. The system is technically a bi-turbine with each kite using the same kite part in the coupling tether; the rotary engines couple rotate at least about the center of rotation at the opposing mooring point of the opposite kite.  The dynamics are not really new, but the practical achievement of manned flight in these systems will be new.  A toy kite dragging a resistive toy boat across a lake holds a demonstration of the physics involved. Names connected with these efforts: Richard Miller (Without Visible Means of Support, published in 1967), Joe Faust , Wayne German, Dave Culp, Dave Santos, Dale C. Kramer, Taras Kiceniuk, Gary Osoba, and others.   This activity is part of tethered aviation and AWECS; one term for the category of activity is FF-AWE or FF-AWECS with "FF" standing for "free-flight."   These systems may be scaled from tiny to huge. And these systems may be designed not just to travel across continents but to so operate that some mining of energy can occur during flight session which mined mechanical energy could be converted to laser or microwave and beamed to other aircraft or to receiving ground stations.

Dale has been detailing many paths for his experiments and eventual trials. Hundreds of days of winds have been examined that show world record free-flight distance records could be set using the FF-AWE method. Onboard he has envisioned auxiliary AWECS for cooling and charging onboard batteries for use in sustained powered flight, if needed. He wondered why he was at the AWECS  HAWP 3009 conference; it was my pleasure to conect dots between soaring editor Richard Miller, my own advance on the FF-AWECS in publishing, Wayne German's pointed talk advance of same, and his patent; his doing are right on target for AWECS, as the system has potential for gaining more-than sustainable energies, energy that could be converted and sent to other aircraft or groundstations via laser or microwave power beaming.  At conference he admitted that the Malay kite in the patent application drawing was for fun, as other kite forms will be used; he opined that kiting two of his Lazair ultralight might do the job.   For Dale C.

Low-tech wins: http://www.drachen.org/journals/a16/Using-kites-to-generate-electricity.pdf
24Nov2009 SwissKitePower,
Your system is an instance of a rotary engine in its first stage: The kite machine has its essential parts: the airfoil, the bridle, control system, tether, mooring point. Those parts of that machine have a turning radially about the mooring point; sometimes the turning with small rotation, sometimes the rotation is greater. Since the system changes the kinetic energy of the stream to mechanical energy (tension, pulls, heat in tether, heat in mooring point parts, sound, motion of the masses involved, etc. , then the rotary engine that it is ...is a turbine, indeed, a tethered turbine.  And we see that your are using that airborne wind energy conversion system in high altitude wind power efforts with the aim to use the mined mechanical energy to further uses like setting up a ground generator to generate electricity for grid or for charging storage devices like batteries or water heads, etc. Wow, this is so much more clean than coal or oil. May your efforts come to full development.
An AWEsome direction to take. Others of like care are gathering at
