Subject: Isotropic Kite in Persistent Flight
The World Kite Museum's Indoor Kite Festival took place last weekend. KiteLab Ilwaco once again performed a public first demonstration of a key proof-of-concept prototype. Last year it was shown that an anisotropic (weathercocking) kite can be maintained aloft in calm wind by phased tugs from three fixed anchor points. This years demo was not quite so fundamental, but still portentous. It was briefly shown (at the end of the event) that an isotropic kite can also maintain flight by phased tugs (a radially symmetric Sedgewick U-FO offered by Joe Hazicki's Revolution brand). The significance of this proof is that future megascale arrays can accept wind from any quarter without having to spin, but merely tilt from veering wind in real time.
 
The three pilots this year were Scott Davis, the founder of the festival, a small kid-star competitor named Ian, and the I-Quad star founder John Barresi. John was very intensely focused on the optimization of this concept. We concur that the flat kite tends to track horizontal and even dig down, so it needs a bit of reflex in the next iteration to improve the flight dynamics. A simple bridle refinement will do. Full-scale soft arrays will require further design refinements, but we are optimistic of the practicality of the general concept space.

I think it is great that you consulted an expert on a relevant topic, so as to learn the well-established facts. Such experts also exist in the field of wind energy. I've found that consulting experts can improve the performance of your system a LOT. Whether you are talking about the field of Intellectual Property or the field of wind energy, both have a HUGE body of knowledge going back over a thousand years. Most problems and topics have been covered many times. We AWE people like to think that we're the first thinking beings to emerge on the planet - that nothing has come before us. In reality, most seemingly new obstacles encountered have been overcome many times in the past, and most topics we discuss have been laboriously worked out long ago.

Subject: Re: Why people patent ideas:
Bob:
The patent system is one place where the small inventor becomes equal to the big boys. It's your foot in the door, if you have a new and useful idea. No need to feel intimidated, any more than you might say "I don't want to drive" because of an already-established, confusingly complex maze of roads, freeways, laws, insurance, breakdowns, accidents, repairs, etc.

The whole idea of the patent system is to empower the small guy and give him an edge. One can currently have a U.S. Patent issue for around $1500 total, if you fill out the paperwork yourself. It takes a couple of years.

The budget-challenged inventor has been accomodated: Initial filing of a provisional patent, capable of providing full protection with future conversion to a full U.S. Patent, cost only $100 to get your priority date, and your first year of protection.

Sure transportation is full of annoying details but it gets us from point A to point B so we suffer through it. Nothing is perfect but the patent system is there for your use, just as the roads are there for you to drive. It is hoped that you will find both the patent system and the roads helpful and useful.

Subject: Re: Why people patent ideas:
The first time I had an idea I thought worthy of a Patent, I spent most of my savings on a patent search.  It found half of the patents I already knew about, so I knew that any further funds would be a total waste.  I know that a few non-millionaires have made money from patents, but overall, I think that the lotteries have much better odds, and are far less frustrating to play.  James Lancaster came from the electronics field, but his screed against patents seems true for most of us.  Companies hate to commit to paying royalties, and will typically budget ten times the estimated royalties to break a patent.  Usually, all it takes is time to drive the inventor bankrupt.  However, I recall a patent backed by Czechoslovakia for a plastic injection molding machine.  Every description mentioned the moving plunger, so the Italians just bolted their plunger to the floor, and moved the mold.  When Bruce Myers invented the Dune Buggy, he got both patent and design copyright protection, and set about filling orders.  After two years, when he caught up, he noticed that he only had 15% of the market, so he called the lawyers.  Two more years, and he was broke, and divorced as well, but the rest of the dune buggy business was still thriving.

Amazing Joe. What inspiring scenery and footage of an amazing concept!
That location in Norco, near Corona, California, is about a half-hour South of Oak Hills where we are located. That hill is about 1400 feet elevation. East of there, you can drive up the 330 to the 18, headed toward Big Bear, and look down from over a mile in height. They call it "The Rim of the World". From that vantage point, you can see a LOT of Southern California, including Catalina Island in the Pacific Ocean perhaps 120 miles to the West.

Further up the 15 Freeway, toward Las Vegas, is the Cajon Pass which is at around 4000 feet. Just past the edge of the pass with its seemingly perpetual cloud bank, we're a couple miles out into the high desert, at 3600 feet elevation, in the highest concentration of homes powered by wind energy in the world. We have miles of relatively clear land upwind of us, so the wind can really get a running start. I'd like to get into ultralights too - we have what seems to be potentially a decent small runway here.

What a beautiful area. Not only is it (usually) perpetually summer, but we have decent local skiing too! Hard to resist - let's see - ekiing / work.... skiing / work - wait lets add snowboarding, skiing, work hmmm so hard to decide when its all so fun!

Subject: Pacific Power Sails Relocates to Seattle
Dan Tracy and his Hawaii circle have been an admired presence in the AWE world for at least five years. They operated a small kite ferry between islands for a time, and hosted R&D visits by top folks like Robert Creighton (WindLift). We followed Dan online in his many small AWES experiments as HighestWind Hawaii, and the launching of a small AWES product (Pacific Power Sails), which further validates the newly hot, but centuries-old, kite architecture of a pilot lifter above a power element. Dan also worked on incorporating a kite-based "Peaceful Solution" vision into Willie Nelson's Peace Research Institute process (link below).
 
Now we are informed by Jeremy Calvert (KiteBot) that Dan has relocated to do R&D in the Seattle area, which is a great addition to the NW AWE scene. We are hoping for a flying meetup soon while Noah Sapir (Util) is still in the region. The following article adds to the long trickle of news about Dan's work-

One response:

Actually, Dan, our AWES-coming world will affect wingsuiters, hang
gliders, skydivers, paragliders:

1. AWES tether sets will need to be mapped and respected by such
airspace users in order to avoid being sliced in half or more parts!

2. Some AWES maintenance workers very well may return to ground base by
wingsuit gliding.

3. One of the coming sports involving AWES will be riding "those wings"
and "climbing those spiderweb tether sets" constructed by the AWE
industry!

4. A coming tourist attraction will be the riding of AWES lines. This
might be extra income for an AWES installation in particular location.
The combination of activity might help an AWES installation to occur
when otherwise such might not occur.

5. AWES installations will be affecting the sport flying sites. Such
matter may be entered to the FAA or other airspace governance for
attention.

Subject: Pendulum and Dihedral Stability "Myth" Demolished
Its common knowledge that the passive yaw stability of a single-line kite is severely limited by its pendulum stability force. Flat kites further rely on dihedral to counter roll. A lateral bridle eliminates the need for dihedral and soft kites are often so based. The sudden "obvious" insight is that "staking-out" a kite across the wind completely eliminates the need for pendulum force or dihedral to stabilize a kite. This use of the surface-plane as the constraining stabilizing principle is great news for scaling up our kite farms with great stability to fly in high wind and turbulence. The pitch axis is a lesser remaining stability challenge; a luffing leading edge is the condition to avoid. A pressurized leading edge, "ski-jump" center nose reflex, and/or a trailing edge flap or tail effectively eliminate plunging dive or somersault; added as needed for required engineering margins.
 
This general staking-out geometry is the "green-light" for megascaling cross-linked kite formations without critical dependence on active servo-stability.

Co-Inventor Greg Smedley and I have met several times in the past. I never knew he had an interest in airships. My advice for anyone filing such patents is to get your stuff built and proven first, even at prototype scale, then file patents for what you end up with. That keeps you focused on what works, rather than what you patented at a time when you had less experience.

Subject: Plucking "Slip-Stick" Line Tug Dynamics
Novel AWES architectural principles continue to emerge. Plucking a kitestring to transmit power is a Brainstorm Special, crazy sounding, but curiously worth pondering. Friction is described as a "stick-slip" phenomenon where by a static load is tapped by a sudden release. A plucked or bowed violin operates by stick-slip power transmission to the resonant body. Plucking a string is like drawing and releasing a bow, naturally operating at high spring efficiency with potential to scale, which makes it yet one more way we might transfer energy down along a kiteline.
 
The useful property of the characteristic sawtooth pluck waveform is its sharp plunge phase whereby a surface load, like a high speed flywheel/generator, can naturally get a fast little kick, without a lot of step-up gearing. Practical conditions to meet- The string must be a quality elastic cell and properly tension cyclically (more tense the better), with sudden release. The plucking mechanism and line pluck point want to be at a fundamental harmonic node, with the line handling chafe resistant. Line-catching/releasing can in principle use low-wear high-duty components. Predictable losses to mitigate are at the upper kite lifting network (should be stiff within the pluck timescale) and there will be added aerodrag at the sweeping pluck point. Downwind line release is favored.
 
An exotic variant is high-speed water-ballasted wings with tow-hooks acting like "guitar-picks", plucking the line to send the power down, briefly hooking and decelerating to deflect the line at great tension, and suddenly releasing it, Rock-and Roll forever ;*)

The following are loose notes toward a formal DOEIG complaint over ARPA-E's AWE program standards and the performance of exclusive favored private parties (Makani/Joby/Google).  
 
It is hoped something finally resonates enough for Director Arun Majumdar to be responsive to the open US AWE Industry on our "forum-of-record" (or any other public venue). If a rationale is wanted for why the complaints and investigative effort are proceeding, its the predictable reaction to extended ARPA-E stonewalling, and lack of visible progress on pretty much all questions raised. Signs of positve progress to resolve specific concerns will put to rest complaints.
 
Keep in mind the loose organization of the material below only hints at the case in its final form. A lot of extraneous paths will be dropped to focus on core issues. Expect an organized draft of the complaint for your review and comment before the DOEIG gets it,

Concept Paper competitive information- What is the withheld portion? Would a FOIA protect such secrets?
 
Concept Paper Evaluation Criteria Relative to State of the Art: Did the applicant really meet these requirements? Did ARPA-E properly enforce these requirements?
 
B-1 Impact "...applicant must demonstrate awareness of competing or emerging technologies and identify how those concept/technology provides significant improvement over those other technologies." Did Makani meet this requirement of somehow get a pass.
 
B-3 Qualifications, Experience, and Capabilities "...applicant's prior experience must demonstrate an ability to perform R&D of similar risk and complexity." This is where CTO's water-ski kite, and the other similar modest "prior experience" of the Makani team leaders compare poorly to career aerospace professionals. ARPA-E rejected competing proposals by top aerospace pros. with the Google connection seeming to have unduly stacked the deck.
 
B-4 Sound management Plan "...applicant should identify major technical R&D risks..." Was Makani made to comply meaningfully or given a pass?

"Due diligence in supplier quality (also known as due care) is the effort made by an "SQE" (Supplier Quality Engineer) to validate conformance of product provided by the seller to the purchaser. Failure to make this effort may be considered negligence. This is conceptually distinct from investigative due diligence, involving a general obligation to identify true, root cause for non-compliance to meet a standard or contract requirement. "

Subject: Distilling Lessons From Fort Felker, and building on them
Fort Felker's 2010 NREL presentation, Engineering Challenges To Airborne Wind Technology, deserves close study and is an excellent foundation for the AWE Industry to build on. The following are notes and commentary to the work, preparatory to TACO integration. Where Fort's terms are super-specialized or non-standard, they are recast for clarity. Comparison with the original document can sort out which ideas are Fort's, and which are appended.
 
Fort asserts the well-known attractions of AWE but focuses on the widely overlooked challenges. He consistently emphasizes that all system reliability requirements must be "explicitly defined" and early on warns that aviation "reliability is expensive", which particularly relates to complex aircraft costing roughly "500 dollars a pound". Some way to slash costs close to "five dollars a pound" must be found. The AWES string and rag KIS school seems closest to this high affordability.
 
Integrated Risk Management is a key part of the general Systems Engineering. A "rigorous risk reduction process" is called for. Fort covers many uncertainties, like who decides to recover after an automated shut-down. The Design Load Case-base to simulate and test must be exhaustive, including common Extreme Events like ECD- extreme coherent wind speed and wind direction change load cases (especially downward and rearward bursts).
 
Partial Failure Cases include Structural, Electrical, and Control System Faults. Fort cites the structural Engineering Safety Margin of conventional aircraft, but AWES operational extremes may require the higher standards of special utility and aerobatic types. The Design Environment is the chosen operating environment state-space, like if the system is to be operated in specific extreme weather conditions. Many kinds of special factors apply, like operations offshore or around populations.
 
Life Cycle Cost Modeling is another facet of Systems Engineering. Fort breaks this down as Development Cost, Manufacturing and Deployment Cost, Financing Cost, O&M Cost, Replacement Cost, and Decommissioning Cost. Land Cost should be added; systems with an extravagant land-need per installed-watt are disadvantaged.
 
Design and Verification Standards are carefully considered. Existing standards from wind energy and aviation are proposed for adoption as practical, but specific new "Certification Standards are urgently needed"; they do not yet exist. Due Diligence remains problematic until the new standards are in place. Third Party Validation is the essential finishing step to design verification.
 
Fort is not alone in predicting that AWES will "grow in size and become more flexible." Larger more flexible systems eventually means soft lattices of large soft (or smaller stick) kites, as the scale limits of single kiteplanes become restrictive.
 
Comprehensive component and field testing gets the greatest emphasis by Fort. Elsewhere he has opined that ARPA-E should be testing a "balanced portfolio" of AWES contenders. He especially advocates Highly Accelerated Life Tests (HALT). HALT will be the main job of many developer teams, with extended testing undertaken in highly adverse conditions, not just in ideal conditions. Even so, tens of thousands of flight hours are required to fully inform us.
 
Simulation Tools is another area Fort finds lacking in essential capabilities and validation. Fatigue Analysis over the design life is a requirement. Aero-Servo-Elastics is a frontier topic- the capacity of a system's own actuation to trigger flutter under specific conditions and the damping required to avoid divergence. Even simulation input data must be validated.
 
Fort echoes a hard reality, that "development of control systems for aircraft has become a long expensive process." A few standard control methods and issues are listed, but this is a big topic, especially for non-piloted systems. Environmental and Human Impact Assessment is mentioned not so much as daunting than as a necessary task.. Fort echos the calls in open circles for collaboration across the industry to resolve common problems.
 
Over a year has passed since Fort laid out these challenges. Lets pick up the pace to act on them and ultimately resolve them. ARPA-E has been formally requested to apply Fort's "DOE/NREL Principles" to Makani's contractually required testing and analysis work-product. Everbody else is hereby advised to follow Fort's admirable template as well.

If you use twice as many "blades" in a turbine, they only have to be half as strong, because they share the available force and energy.  The main merit of the classic water pump turbines is that they have a high starting torque.  Efficient designs only pick up the energy of the whole swept area when turning an a reasonable speed.

Tigner has a stellar aerospace resume and a physics PhD, and even worked under Master Kroo. He has military-industrial affinities in his past work, but this does not strongly predict a Dr. Strangelove mentality.
 
I hope to show priority in the tri-tether AWES concept space, with many public disclosures. Perhaps he has also lurked on or reviewed the AWES forum? The tri-tether phased tug concept is clearly hot if top aeronautical experts like Tigner are converging on it. We also know the tri-tether really dates to at least the airship era, and its a small obvious step to see in it reversed energy transduction. Tigner even shows dense arrays, but unconstrained by an upper meshwork, overlooking the pilot-lifter (unit or layer) that allows full passive stability with close packing. It will be a long time before UAS automation is robust enough to do his conception of dense arrays.
 
I would love to work cooperatively with him, as he seems very talented. He is Cc:ed this, so lets see if he replies.

Subject: Perpetual Kite Materials Engineering
Large-scale AWES kites might have a very long service life. We know that large UHMWPE cables capable of mechanically transmitting many megawatts can last decades in service if protected by known means (chafing gear (sleeves), coatings, etc.). A giant soft-kite load-path network can be made of this stuff and be relied on to survive almost indefinitely.
 
The problem is the infill membrane, which in the current state of the art will "only" last about 15,000 hrs in normal high-duty use. It should be practical to adhesively laminate new layers as old ones degrade, preiodically exfoliating old membrane from one surface as the other surface is renewed. Many options exist as to the number and composition of sandwich layers, and how to adhere and ablate them.
 
This is a simple skin-like biomimetic method. One can even imagine an immortal bamboo and paper kite, always repaired and renewed, lasting "forever".

Maples and Hagewood [1973] is a nice missing-link fossil tri-tether citation. Of course there are many similar "stable airborne platform" experiments from the Golden Age of modern kiting. This method can be combined with a persistent-flight phased-tug pilot lifter for a "perfected" revolutionary airborne platform.

A wind energy generator for employment in the jet stream or other wind conditions is described herein. The craft comprises a "kite" configured with an airfoil and tethered to a ground based power generator. The craft and tether are configured to pull on the tether during a flight pattern calculated to pull on the tether that is connected to the generator to enable power generation. Also, an aerodynamically stable tether configuration is used and can be supplemented with a number of periodically spaced control surfaces arranged at various points along the tether. These control surfaces can be selectively actuated to stabilize and position the tether. The tether can comprise a two-stage tether having an inelastic portion attached to a pool and an elastic portion that connects with the kite. Also, the invention contemplates a system of wind detection devices that identify the local wind variations and through control systems enable the optimal positioning of the kite.
