Subject: "High-but-not-too-high-altitude wind potential"

Interesting article on www.governorswindenergycoalition.org/?p=8575 .

Some extracts:"They found that there were several regions that were particularly rich in high-but-not-too-high-altitude wind potential, like the Somali jet stream that blows along the Horn of Africa, as well as the American Midwest, where traditional land-based wind turbines are already proliferating at a record pace (ClimateWire, April 11).";

"These widespread “sweet spots” are located at about altitudes of about 1,600 feet, about 400 feet higher than the top of the Empire State Building and about 1,000 feet taller than today’s tallest wind turbines.";

 

"One of these areas is the U.S. Midwest, Archer noted, where wind speed maxima called “low-level jets” are currently a nuisance for wind farms. When they blow above the arrays, they stress the turbines’ blades, often forcing them to shut down.

But if airborne devices were deployed in the same place, low-level jets would become a help rather than a hindrance because these are exactly the winds that work best for this technology.

“If you have both, they kind of complement each other,” Archer said."

 

A better knowledge of atmosphere and available "low-level jets" (mentioned also by WayneG) spots, comprising also oceans, is the departure point for a later viability of AWE. Thanks to Pr.Archer to take into account of specific challenges from AWE (mainly the needed limit of tether length) to study "low-level-jets" and thus bring perspectives.

Subject: Re: Wind turbines dissipate hurricanes?
Cleventine,

Now is a good time to introduce you to Mothra tech, which was introduced on the AWES Forum as the most-scalable unit-aviation basis (by size and lifting power). Its also the cheapest and lowest-complexity known solution in its application-space. If you want to be Captain Ahab or SeaWolf of the sky, and command the winds, this is the tool. KiteLab and kPower has designed, built, and publicly flown at 1/40 scale (300m2 70m WS) wing, with several follow-on wings flown or in process. The World Record largest kite is pending (

Subject: AWEC2014 at US NWTC?
Fort Felker, Director of the US National Wind Technology Center (NWTC) in Boulder, Colorado, is expressing a strong interest by email in hosting AWEC2014, and particularly invites AWES technical demonstrations.

As usual, a large volunteer effort is required to make the event a success, so please contact JoeF or particular leads in the various aspects (academic, demos, biz, hospitality). An organizing committee of such leads will form.

Boulder is a wonderful town where mountains meet plains. A date is not set, but avoiding seasonal peak-snow conditions at nearby ski resorts is helpful, for cheaper easier lodging and transportation. This implies an early-fall or late-spring event.

I like the idea, How many RPMs you thinking of getting off this?

Also, if one bungie system fails.. will the device still be able to spin?

The shape.. I know you have a reason.. but bernoulli's law? 

(also did you see the response to my previous you tube post? i hope you better understand.)

Some questions: 
1. How much will it cost to lift the water to tower height?
2. How much will it cost to spray the water at the tower height?
3. How much will the heat of compression of the falling air play in the equations?'
4. How moist will the processed air be?  Will there be corrosion issues?
5. Fifty years of fixed water pricing? How much will water really cost during the run?
6. ?

Thanks for your interest...
How many RPMs you thinking of getting off this?
fully depends on scale. Not sure. estimated @ 100rpm @ 2m dia... no idea really

Also, if one bungie system fails.. will the device still be able to spin?
I expect rougher and lumpier flight if anything started failing... But with it being based on single skin tension... rag and line only... It should be able to keep within a safety and reliability factor.
Grade the transition points, joins and cuffs.. lock the knots...

The shape.. I know you have a reason.. but bernoulli's law? 
Can you explain what your point is here please?

(also did you see the response to my previous you tube post? i hope you better understand.)
Eh no, sorry. Strangely I can't find that video any more.

Compare dry air with humid air for density. 

Why Humid Air Is Less Dense Than Dry Air Is

Just maybe the company Solar Wind Energy Tower has missed something as they have the water-introduced air as making the air heavier; but that does not in first blush match the physics of humid air.  

Just maybe the company Solar Wind Energy Tower is missing the following opportunity; they might have things just backwards. Their demonstration is a art video, not a physical working demonstration.  

::: Offer to them from kPower:  
Humidify the dry ground-level air near the ground; let the less dense humidified air rise in a tower; Place a rotary blade in the tower as the rising air drives the blade. Let upper atmosphere cool the humid air to collect water out of that humid air; let the water collected at high tower be dropped through a pipe to drive a water-head hydro-turbine make electricity also.   CC 3. 0 BY NC SA  ~ JoeF.

Bernoulli's law, I don't know.. If you incorporate more of a funnel like shape, you'll increase the air pressure at the end, possibly creating more torque. 

Also if the parapoils were arranged like this 


It would be far more effective than the 2d arrangement.. What im saying is..

I hardly need to say anything.  Anyone who has paid attention to my posts can just "channel" what "Doug would say" and save me the effort.  Nevertheless, I can't resist a couple of observations:

Positive: I don't think I've heard this one before...
(Is that because it's too dumb for anyone to have publicized it?  Or is it the long-awaited neglected obvious solution that was in front of our noses the whole time?  Votes anyone?) (Hey my mind is open just a crack, but this has most of "the symptoms"...

Negative:
1)  What happened to the giant solar-wind towers of Australia and Spain from a couple years ago?  Same tower with fans around the periphery of the base, except it used sun to warm air, that went up.  Same extravagant claims, same null results.  Except nobody ever bothered to actually BUILD these giant hollow towers.  Hmmm...  But if they HAD, they might have claimed water injection near the base would reduce air density by evaporation, enhancing the UPWARD flow... (see below)

Wait - I just checked, it's going to be "the tallest structure in North America":

The small southwestern Arizona town of San Luis has approved the $1.5 billion Solar Wind Energy Tower Inc. project, which will result in the tallest structure in North America.

Bloomberg News reported today the structure would be 2,250 feet tall.
(The good profethor ith never content with thmall thepth.)

2) Dare I invoke the good professor?  His solutions to "improve" wind turbines, currently built with about 2% solidity,  inevitably instead use 100% solidity.  He never explains how it will be more economical to build a 400-foot-tall concrete structure with solid walls, than to hoist up a few slender blades using a crane and be done with it in a few days.  Hmmm...

3) Let out aviation experts verify: humid air is less dense than dry air, and lighter in weight.  That would "weigh against" the higher density of cooler air.  In the end, does the increased humidity cancel the cooling effect, resulting in no net density change? (They MUST have thought of that, right?  But some of you may have noticed that the average idiot maintains that humid air is HEAVIER than dry air because, they say, "it MUST be"...)

4) That is a lot of water to use, in a desert that always needs water.  Fresh water in a desert = energy = money.  Do they have numbers?  Sounds like enough water for a decent-sized CITY.

5) Does the energy gained even cover the energy needed to pump the water to height?

6) Where's the scale model to show how great it works, so we have the confidence to build a bigger one?  Or does it serve them better to remain in the good professor's office, while they sell stock ) ticker symbol SWET
http://finance.yahoo.com/q/bc?s=SWET  Looks like it's tripled in the last few weeks.  Can you say "pump-and-dump"?  Before that it had dropped by almost 100%.

7) Looks like the company has been around as a penny stock for 10 years.  In 10 years what is the biggest demo they've built?  Why not? 

In summary, this has the good professor's grimy fingerprints all over it, like his glasses.
Sounds like a sexy idea, but is there anything there at all?  If so, how could they have resisted building one?  Oh wait, gosh I hate to bring it up, but one of the good professor's major symptoms is "We can only build our first prototype at an absolutely GIGANTIC size, becuath, you thee, we are theriouth about thith, and are not content to meth around with thmall-thcale tholuthionth!

My advice to the profethor:  FInd an existing scenic waterfall on a cliff somewhere, ruin the tourist attraction to build an enclosure around it, and see if it even works! 

Why would any one talk about a giant version with all those fans around the periphery, when they could just build one tube and use one fan to prove the concept first?

Ah, forget it.  Seems that there's no field so full of nutcases than clean energy.  And the city officials that approved this?  More rocket-scientists, no doubt.

Will they ever build this tallest structure North America?
Should we place bets?
drumroll pleathe....

OK I'm done.  :)

Put some more thought into it.. If it was a semi-rigid- logarithmic spiral ribbon( perhaps some bridles), with the narrow end of the cone pointing towards the wind, you could possibly model a smaller version . There's no doubt it would work!

just saw a new patent on that exact concept the other day.
before that we had "spiralairfoil" from Dan'l
before that we had DaVinci sitting in an ivory tower, looking out at windmills, which had already been the main industrial power source for Europe for 500 years, deciding he knew better and so designed a non-workable 100% solidity spiral helicopter that has never flown to this day.  It took 500 more years until someone finally got a clue.  DaVinci is also credited with "inventing" the battle tank, but if you look close, it wouldn't work either - the crank turned the wheels in opposite directions.  wah wah wah.  Kids in junior high school draw better shit than that.

By the way my comment pertained to "semi-rigid- logarithmic spiral ribbon".

Unfortunately, Yahoo Groups is getting harder and harder to follow the thread of a conversation.  They're really making us work for it now.  (let's see, if I can click enough to figure out what comment this comment pertains to...) 
Ever notice how just when software finally gets perfected, they feel a need to "update" it, making it harder and harder to use, until you don't even want to try anymore?  Microsoft (named after my weiner?) recently stopped supporting the only decent version of Windows they ever had - XP.

Subject: Looping Parafoil session passing 1 week and 100 flight hour marks...
kPower's 1.2 m2 Looping Parafoil AWES has been field-operational for over a week now*, and is close to the 100hr mark of flying hours. During the session conditions have ranged from calm to blustery 35mph winds. Dave Culp knows how gnarly these Texas conditions are. Turbulence is often extreme, offering accelerated testing. FAA night flight restrictions have not been deemed applicable since the entire small-scale experiment flies under 50ft.

Self-relaunch is consistent. The rig has now relaunched itself more than 100 times. Wind-field chaos that perturbs the AWES also drives recovery. Malfunctions have been minor. There is one rare stuck state (happened once) of the parafoil, to be eliminated in the next rigging iteration; A failure of a pilot kite batten pocket also occurred, causing one of four sticks to be spit out, but the kite flew on without the stick, and the repair took a minute.

All in all, the rig looks as good as day1, and flies better than ever, by many small refinements. The endurance session continues, with work-cell experiments currently being tuned and swapped. An elegant production design is emerging from the accumulated hands-on experience with the prototype.

Ok! I see how it works! That's clever, and very simple.. I admire good design. I was laboring under the assumption that one line(-) was attached to some sort of rotating plate but it appears it is attached to the line.. was concerned for a bit that we might have similar designs.. 

It just so happens you can't patent a theory and we require the same principals with each of our orbital machines. (Maybe that will give us more credibility.. We're starting to sound a bit loopy lol)

I, for a while now am impressed that I can't readily find kite turn radius statistics. Ex. Given wind speed x and line differential y what diameter loop will be preformed. (And String length)

The theory will need to be translated into programming but when it is they will be able to fly deeper into the wind window.. This research is imperative.. I'll post a lab write up in a few weeks on the symphony beach 2.1 seems a lot of people use that one. 

Also, can you manipulate the foil while it is underway?

To control the looping kite during flight we plan to use hollow-bolt swivels (like BMX stem bolts). This will mainly be to depower/kill the power-kite, since line presets are enough for good trim.

Yes, small AWE is childsplay, but we had to navigate trillions of possibilities over many years to get so near to KIS COTS.

Turn Radius is set at about 10ft and RPM is about 60, with passive-variation to match conditions.

Radius and RPM are modulated by line presets.

The foil looping video was good, we need more of this so we can find the optimal kite, RPM and radius so we can predict output power. 

It seems my AWES will work best on a boat, and that looping would provide TREMENDOUS torque with a bigger foil.. So long as the lines don't twist.  So you see why I am concerned with the radius, rpm, string differential, for me, it's easier to think of these systems as engines.

Subject: Leo ?

LeoG did not answer about the "no tether drag" challenge; I saw tether drag where he stated "no tether drag."

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

Now another item he just published in his April 2014 "industry report"

"This site does not consider Altaeros Buoyant Airborne Turbine as a true airborne wind energy system"

=========  My polite reply: 

Though your site does not see BAT as AWE, the mechanics of BAT qualifies the BAT as true form of AWE; such categorization has been true for many decades and remains so by the Airborne Wind Energy Industry Association international and by EnergyKiteSystems. The BAT is a kite system with a wing that is LTA; the BAT holds flygen and thus is an airborne wind energy system.

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

LeoG is welcome not to see drag that exists. And he is welcome to classify BAT as he wishes. No problem there.   However, he might have to face some music down the line when drag shows up and BAT is widely a true AWES. 


First blush guess is that Leo, now in Austin, Texas, is carving out his corner as the defining corner of AWE while ousting tether drag and ousting BAT as AWES.    Troublesome trend, my guess.

Subject: kFarm AWT session now reaches 2 weeks, ~200hr marks
The kPower looping parafoil AWT has now been operating 2 weeks for nearly 200hrs of flight-time. Its still relaunching and looping just as it began. Workloads and pilots were swapped for comparison, and the rigging geometry varied during the session; for improved design. The looping-foil element has experienced extreme conditions of "thumping" repeatedly in high winds, but remains sound. The unstable mistunings causing crashes ran for extended periods, for HALT (Highly Accelerated Lifecycle Testing) observations.

The marathon AWE session continues. Dummy and pneumatic loads will give way to new electric work-cells. Rigging details are being perfected. A passive turret-post*, with integrated work-cell, will be tested, as the final major element needed to make this a practical AWES. Once the all-up ensemble is working well, rounds of data-collection (multi-sensing, videogrammetry) and third-party review will begin.

A possible "first" last week was when the kFarm crew went into town, leaving the AWT running unattended; no problem...


* AWES turret-posts were an early kPower innovation, by hosting multi-reels on a vertical axis. In this instance the vertical spread of pumped PTO and main anchor neatly avoids dispersive lateral jerking of the turret, without a dash-pot (CC 3.0).

Subject: turret tornado and lifter set
Been trying to devise a tilt table which allows a generator to follow a tornado type without having gyroscopic rotation imparted to the follower base when you resist the torque...

So I devised this...
Gen sits on a plate on top of a UJ. Around the plate are hinged follower rods extend out and slide through a following guide tube.
It's probably completely over the top as the fixed UJ wouldn't allow rotation in the first place.

You might have a better solution.
Like , a ball head with tracks for pins under a cap
or
offsetting the gen mount 45 deg on top of UJ in the design above.

The tilting follower is the last of the 3 basic components for an anywhere tornado device.
It's certainly a bit early to start speculating the possibility of being able to 3d lattice array these 3 basic elements ... but that didn't stop me at the end of the video.

Thanks in advance for advice ...
