Hey C-Spartan Wink (I still love that name!  grin )

 smiley

What happened here is small potatoes compared to what you guys have had recently.  I try not to judge other countries/cultures because I'm not there and not living the problems.  When I saw the severity of what happened in Greece I thought that it would never happen here Wink [Still hasn't, but it certainly looks possible now]

Though I'd add that the Greek protests were political, whereas the London problems were criminal.

What is happening in Greece is, as you know, different than the UK riots.   There are serious underlying social problems here, as compared to the UK and US.  These in turn have greatly contributed to the economic mess.  Things now are quiet only because most people here are on holiday (I wonder how it is that they still can afford it).  This fall there may be further disturbances.  

Yes, the focus here was "political", but I think it might more accurately be described as economic.   There are specific segments of society here who are at the forefront of the "disturbances" - trade union activists, unemployed young "anarchists", etc...These people tend to be the ones who actually try and goad the police into fighting.  The majority of people are upset, may protest, make noise, but the ones actually throwing the moltov cocktails and confronting the riot police are not a sizable proportion of those actually demonstrating.

I am reluctant to say much on the Greek situation, because there are several segments of Greek society who are partly responsible for the mess, each in different ways.  But to get back to the topic of this thread, Greece may not be in full-fledged social breakdown, especially now that it got another loan, but the repercussions are going to be felt for years, and I think that there is great potential here for further rioting, though different in character than that in the UK.

I can only hope that in the long term, at least some lessons will be learned.  Over and out Point-Dog  grin

Glad to see Point Dog contributing to the conversation.

I too was glad to read your post, Point Dog, and I was also glad to read see some encouragement by Guro Crafty and others, regarding getting other viewpoints.  There were also posts here, by some who disagreed, but nonetheless came across as welcoming a different viewpoint, and the chance to debate the issue.

There also seemed to be a minority who disagreed, and came across quite differently.  Guess this is why people like Point Dog and myself don't much bother posting in such discussions.

C-Spartan Dog, I will try to cut it short:....

Some examples: A guy who is forty years old will be healthy and will still have some strength, but his agility is not the best anymore. So it would make no sense to give him a "Round-Shield", where he should be kneeing most of the times, crouching on the battlefield, and than move fast as lighting...


This is what I was looking for..an overall idea of what lines he was thinking along..thanks for elaborating on this  Smiley
57  DBMA Martial Arts Forum / Martial Arts Topics / Re: Other Weapons on: July 31, 2011, 10:06:23 PM
...In an old book which is written by a General of the Ming Dynasty, he describes which criteria they used in the military to decide which guy should use which weapon.

I'd be interested in hearing a bit more about this...

Woof:

Sounds like this Euro Gathering was a huge success! Congratulations to everyone involved especially Guro Crafty and Guro Lonely!!

Out of all the Dog Brothers Martial Arts Association European members, feel the 'closest' to C-Gong Fu Dog and candidate DB Kostas (what's your DB name going to be?) - Congratulations to both of you!!! Cannot wait to check out the 3 Sectional Staff fight!

Very truly yours in the MA and SD,

~sg

Thank-you...my Dog Candidate name is C-Spartan Dog, as noted below.  The funny part is, I've passed through Sparta, and I'm not particularly attached to it...furthermore, I've yet to see the movie 300  - so why Spartan Dog ?  When I attended my 1st Gathering in 2009, I was so so hyped up, I feel I fought better in that one, than in any since.  Several people remarked on this and one tribe member wrote me something to the effect that it was as if I was trying to keep my opponents from "getting past" me.   This made me think of the Spartans at Thermopylae.

My dream, is to someday fight again as well as I did at my 1st Gathering.  I hope I can fulfill it.
59  DBMA Martial Arts Forum / Martial Arts Topics / Re: European “Gathering of the Pack” 2011 on: July 16, 2011, 10:31:43 AM
Stickgrappler, Xiexie!! Kostas name is C-Spartan Dog, which fits him quite well-Not because he comes from Greek, cause he fights like one!!

Truth is, I stand my ground when sometimes I should not...maybe I should start thinking less like a Spartan - it certainly would result in less colorful bruises  wink

I still have so much to learn with my weapon. I feel I just scratched the surface of the weapons potential...
But thanks to Guro Crafty I got now lots of new ideas!!! I´m so grateful that he helped me with my game!!!!!
So hopefully in the future I will use the whole potential from that weapon and will fight better...well, at least I will try  smiley

I'm happy to hear you so passionate about this...it shows in your fighting that you have given a lot of thought, and put in work towards really expanding your fighting skills with the 3SS.

I'm already in London, yet the days at Bern are still running through my head. I really enjoyed being a spectator in this Gathering; both the comradeship and the intensity of the fights were amazing.

I'd like to thank all the great members of the tribe I met. Guro Crafty and Guro Lonely, thanks for some great training sessions. I'm sure it'll take me a long time to fully absorb everything we saw. Kostas, Colin, Thornsten, Chris and anyone else I may be forgetting, thanks for the friendly conversation and advice. I look forward to seeing you all again next year, hopefully as a fellow fighter in the Gathering!

I very much enjoyed meeting you and chatting...I'm only sorry you did not manage to make it back to the Campground afterwords, so we could hang out longer. Hope that the rest of your trip is fabulous.  When you return, please give my regards to Nicolas - though I've not met him in person.  Hope to see you again next year  smiley
61  DBMA Martial Arts Forum / Martial Arts Topics / Re: European “Gathering of the Pack” 2011 on: July 12, 2011, 04:28:25 AM
Kostas, it was good to see you again my friend...Congratulations on becomming Candidate! You deserve it! Looking forward to see you again next year smiley

Thank-you...and yes...it was great to see you too, my brother!

I want to thank you for your encouraging me to attend, though I have had a difficult year.  I would also like to thank you for your coaching me in my fight against 3-D Dog, which would have gone worse for me, were you not there.  And last, but not least, to let you know that we are grateful for your expanding DBMA through your 3-section-staff work with Crafty Dog's help.

It was also a pleasure to meet your wife and son, my friend, and I hope to see all of you again next year  smiley smiley smiley

Greetings all..am writing from Zurich airport...waiting to return home

This was my 3rd Gathering and I believe that this time the level of fighters was better than ever.

C-Gong-Fu Dog did very well....Guro lonely had an intense fight...amazing to watch him explode into action with a flurry of hits,..

My Bulgarian friend Pavel - a strong contender at his first Gathering, integrating kicks into his stickwork quite well

I managed four fights in the day...thanks to Point Dog, Pavel, 3D-Dog, and C-Lena Dog for helping show me the weaknesses in my game.

There were a number of promotions, which I leave to others to announce here.

A GOOD Gathering...a STRONG Gathering.

Respect to all those who fought, and have fought.
63  DBMA Martial Arts Forum / Martial Arts Topics / Re: European “Gathering of the Pack” 2011 on: July 03, 2011, 09:41:46 PM

Does anyone know of any other place I can stay in other than Camping Eichholz? Apparently all the rooms are booked  sad. I'm travelling alone (backpacking through Europe) and intend to attend the gathering as an espectator and attend the three days of training (the looks I've gotten from my sticks hanging out the backpack at train stations are priceless). Any hostels / cheap hotels to recommend?

Thanks in advance!

The following was NOT cheap (80-90 euro a night) but I stayed there last year and was happy with it.

http://www.kreuzbern.ch/

Be forewarned...it has rained at most of the Gatherings held in Bern.  As for the rooms at the camping, they usually get booked months in advance.  I believe there is a hotel much closer to the camping than the Kreuz (which is  in the city center)  - namely the Ambassador - Guro Lonely or Point Dog can fill you in.  I am not so sure that it is cheap.

I will be pleased to meet you - if you see me, please come and introduce yourself - I arrive at the last minute, and will probably have my mind on the fights, but after the day is done, I'd be interested in hearing about your  backpacking around Europe - in younger days, I did a lot of traveling, and still have a number of friends who do.

Just back from seeing my surgeon, there is a possibility I won't be fighting this year  sad

I have a chunk of 'missing' cartilage behind my right knee cap and will require an arthroscopy to 'find and remove' it.  Depending on when I can get operated on this will mean that I may not be able to fight  cry

I'm sorry to hear that...it sucks big time...no two ways about it  sad

In short, I do not believe that the human body is weak; it is capable of feats that are borne in dreams.

This is not the impression I got from reading your post.

Power generation to accomplish what I described is simply not a problem.  Your experiences in not being able to generate it may mirror your belief that it is not common or possible (certainly not my problem). 

Really ?  How do you know what I am and am not capable of ?

I am 51 years old, and I have been active in the fighting arts since 1979. I am training to fight at my third Dog Brothers Gathering this spring. I am a member of the Dog Brothers Tribe, and I am proud of the fact that this honor has been granted to me. The opinions of those tribe members who I have had the honor of meeting and fighting against, are those that matter to me.
69  Politics, Religion, Science, Culture and Humanities / Politics & Religion / Politics - Why Bill Clinton was "disliked" in Greece on: March 10, 2011, 01:48:19 PM
Does anyone recall which thread Kostas posted on?

I wanted to ask if he would please clarify his mention of Greeks not liking Bill Clinton.

I think he said they preferred him to Bush and Clinton both of whom they saw as more aggressive.

I was just thinking again about his comments about Clinton.

Never have I heard any group not be happy with Clinton for bombing of Serbia.

Listening to the US MSM Clinton is made out to be the equivalent of a Greek adonis (at least with regards to politics) whose bombing of Serbia was a stupendous success.

There are always two sides to every story and I wanted to hear more of the other side from Kostas if possible.

I'm not much one for discussing politics, but I'll try to give my impressions as best I can, on this issue.

Bill Clinton's bombing of Serbia :  It is not that Greeks liked Milosevic - everyone realized he was out of control.  But bombing was just too much for them...Firstly, the risk of civilian casualties.  Second, the worry by many Greeks that incidents of cancer would rise in Northern Greece because of the bombing.

Bill Clinton's support for Kosovo - Greeks believed this had everything to do with the US furthering its influence, and little to do with genuinely caring about Kosovo

Bill Clinton's support of Skopje, and its calling itself Macedonia.

Greece had been a US ally for years, providing military bases for America.  Greeks felt that Clinton did't give a sh** about them and their country.

Hope that helps a bit...I think I'm not giving enough detail but its late and I'm off to bed.

While I understand the emphasis on active head protection ( as it is easily the best target), a strike to the head is typically followed by a cross-over to the upper ribs or another target of opportunity.  Even with a light stick, ribs and arms will break.  Not to mention the incapacitating target of the upper hip (the body can not move to escape the force of impact).  This can land you several days of not being able to get out of bed.  How do folks deal with this? 

All of this is viewed in the light of, once you step up, your personal safety is not ( and should not be) a concern of your adversary.  Your own safety must be your concern.  Footwork will do a lot, I agree; but at the end of the match, one of the combatants must go down.  My question is more along the lines of how this is done so that everyone can walk away from it massive medical expenses.

Your post reads as though the whole thing worries you....I mean...REALLY worries you...

"Even with a light stick, ribs and arms will break"  you wrote WILL break, not MAY break...

Then you wrote "...the incapacitating target of the upper hip..."

Incapacitating ?  Really ? 

If you believe that the human body is that weak, then in my opinion, your experience will mirror your belief.  I myself am only about 72 kilos and not that sturdy.  At the last Gathering, I had bruises that swelled up considerably.  But I never let all that worry me.  My only concern is being able to fight at the next Gathering, and doing well enough for me to be happy with myself.
71  DBMA Martial Arts Forum / Martial Arts Topics / Re: R.I.P. C-Desert Dog on: March 06, 2011, 12:25:47 PM
Since our posts are  helpful, please allow me to share this story....

I got to know Abu at the last Gathering....he was "Dog" Abu then.  Our fight was the first day - and he was a difficult opponent - he would switch from right to left hand as he was zooming back and forth, so it was tricky to know where his next attack would come from.  However, his "style" was not frantic - it fitted him well, and was natural to him.

The next day, as we headed to the gym for the 2nd day of fighting,  I said to him "...Abu, I have the feeling that at this Gathering, you will be promoted to Candidate Dog Brother..." He seemed not so sure about that - though he was confident about his fighting, he did not have an overblown opinion of his abilities.

The next day, not only was he promoted, but Guro Crafty singled him out as having developed an interesting and effective personal style.  Though I did not know Abu well, I remember him as full of energy, good at what he did, yet humble.

I've said before, he will be missed. sad

I'm glad that my impressions were of value...there are things I did not quite get much into...perhaps for another time.  BTW, it was Crafty who encouraged me to join in the discussion...I tend to avoid political discussions, by and large.

As for Obama, I am aware of the greatly differing views that different Americans have of him, though lately I think that even his supporters wish he was doing a better job.  Yes, Americans are viewed in a more positive light in Greece because of his "less forceful" foreign policy.  I don't think Greeks believe that America is becoming timid; Greeks are well aware that America is quite ready to use its military muscle, if it felt it had to.  But to this day, Greeks remain suspicious of American intentions - especially after the Kosovo issue...but then I am rambling in a thread meant for Anti-Semitism..sorry..over and out..and again, thanks for the positive feedback.
74  Politics, Religion, Science, Culture and Humanities / Politics & Religion / Re: Anti-semitism & Jews on: February 22, 2011, 01:59:11 AM
Kostas,
Thanks for the inside scoop.

One question on this statement you made,

 "In fact, I have also heard many Greeks declaring that they dislike Americans (or more specifically American Foreign Policy)"

Here the main stream media would have us believe that Obama has done a lot to improve our image overseas.
Do you think this is true from you vantage point?

Obama is perceived as not quite so ready to resort to military action, as was his predecessor and those around him (Cheney, et al).

So I do believe that yes, the current US administration, is viewed more favorably than the previous one.

Clinton was very UNpopular due to his bombing of Serbia - not just because of Greece's traditional relationship
with Serbia (both are of the Eastern Orthodox faith), but also because Greeks were worried that the actual
compounds used in the bombs themselves contained cancer-causing agents, and would affect the health
not just of the Serbs, but also the population of Northern Greece.

However, the Greeks right now have a lot of problems they themselves have created, and have to face up to.  The
more "responsible" Greeks will admit that Greek society itself is largely to blame.  But there are also many who
prefer to lay most of the blame elsewhere.

As for racism in Greece, there is a strange sort of "reverse racism", that has some (especially the media) being
extremely sensitive to minority rights, so much so that it leaves me wondering.  Greeks are not usually so
concerned about their fellow man.  Many involved in business think little of cheating one another.

It is interesting to note that successive governments have cynically exploited immigrants by charging them quite
a bit of money to renew their residency permits.  That money does not necessarily find its way into state coffers.

In Greek politics, the digger one deeps, the more disgusted one becomes.  But as for the Jewish,  who here really thinks that
they are an issue ?  The waves of immigrants from Pakistan, Afghanistan, Albania, Africa, etc are an issue.  The Jewish are not.

P.S.  Mikis Thedorakis, the famous composer quoted in the article may or may not be anti-semetic.  As he ages, he is known
       to do or say things that will attract attention to him.  I don't think his attention-seeking statements are taken seriously
       by many.  He was, in his youth, courageous and a revolutionary, but he is now in his 80's and not at the forefront of things
       anymore (unless it is to receive some sort of award)

       As for the far-right, they are more concerned with Pakistanis, Afghans, blacks - the visible minorities, than the Jews.  The
       far right, just like the far-left, have always existed - they play on people's insecurities.

      Greeks have always been a seafaring  nation, a nation in contact with many cultures - though they have their faults, in my
      opinion, they are not racist in the sense that they instinctively dislike foreigners.  Greeks are concerned about what the
      legions of ill-paid young men from other countries will do, now that there are less jobs and less money.

Anti-Semitism flares in Greece

Greece, more than many European nations, continues to wrestle with strong anti-Jewish feelings. Such sentiments have been revived amid the angst and anger of the Greek economic crisis.

By Anthee Carassava, Los Angeles Times

February 21, 2011

Reporting from Athens


Well, I have been living in Greece for quite a few years now, and although I haven't checked the facts of this article, my personal opinion is that it is not quite accurate.  Living and working in Greece, I feel that people here are A LOT more concerned with other matters, than anti-semitism.  The "lets blame the Jews"   slant of this article seems to be designed to ruffle Jewish and American feathers.  I can say from personal experience, the many Pakistanis, Bulgarian Gypsies, Albanians, and Romanians living in the center of Athens, concern everyday Greeks much more than Jewish people.

Greeks are more concerned about rising prices, crime rate, and loss of income, than being anti-semetic.  These are very serious and very real concerns that are affecting me, and many people around me.  I have yet to personally see or hear of a single case of anyone blaming the Jews.  I have seen and heard numerous cases of other peoples (I referred to above) being blamed. In fact, I have also heard many Greeks declaring that they dislike Americans (or more specifically American Foreign Policy).  Not heard any complaint about the Jewish though.

The HUBER MILLS Digital Power Report

Gates in the Grid

Soft Switching Technologies and Intermagnetics General

Two other, closely related technologies to watch are the superconducting transformer and the solid-state soft switch.A superconducting transformer? AMSC and ABB have collaborated for a number of years building a prototype.

So have Siemens and Hydro-Quebec, Toshiba (TOSBF) and TEPCO, Waukesha Electric and Intermagnetics (IMG). They work. They’re more efficient (which can lead to serious savings in 100 MW boxes) and they’re a lot smaller - the two-story house shrinks down to a mere UHaul trailer. But at high-power AC, even superconductors develop inductive resistance (small magnetic vortices that dissipate power). The problem can be solved, and has been, with clever geometries and changes in materials.But no very attractive configuration has yet emerged.

If one does, Intermagnetics General Corporation (IMG) could well have a hand in it. Founded in 1971 as GE spin-off, IMG went public in 1981. It now ranks as a venerable pioneer in commercial low-temperature superconductors for magnetic imaging in medical applications.

Last February IMG launched a new subsidiary, SuperPower, to take charge of IMG’s high-temperature superconductor technology. (AMSC is entirely anchored by high-temperature superconductors.) Intermagnetics has already collaborated with (privately held) Southwire and the Department of Energy to build a prototype 100- foot superconducting power connection at a Southwire plant. The company’s most intriguing project is a superconducting fault current limiter - a very fast, smart, powerful, circuit breaker for big substations, which IMG is developing in partnership with Waukesha Electric, General Atomics, Lockheed Martin (LMT), Southern California Edison and Los Alamos Labs. The 17 kV pro- totype can absorb enormous quantities of current - the "fault" - almost instantly. It’s more efficient, robust, reliable - and smaller - than the units it might replace.

Then there’s Soft Switching Technologies [(SST) still private]. For the most common, relatively modest power sags that plague the grid, super-fast powerchips alone can often take care of things, without any additional energy storage device at all. The most important practical application here is one step below the substation, on the internal, local-area power grid of a power-hungry corporate campus.

A single General Motors (GM) factory, for example, requires nearly two-dozen 2 MW transformers on its premises to handle its power. Ford (F), Novell (NOVL), Lucent (LU), and International Rectifier (IRF), have comparable scale private grids on their property. All are already customers of Soft Switching Technologies (Middleton, WI).

Some 90 percent of the "faults" in grid power are created by "first reclosure events." Think of it as rebooting the substation. A sudden current surge downstream suggests the possible need to shut off power flows through the substation completely. But is such drastic action really needed? Perhaps the suicidal squirrel won’t linger. The substation’s hardware doesn’t know, so it opens and immediately re-closes a huge switch, once, and then again, and then (if it must) a third time, each time hoping that the problem will somehow have gone away in the meantime. Which indeed it will have, if the current-surging squirrel has been vaporized. A single reclosure event typically lasts about 12 cycles, or 1/5th of a second. Which merely blinks the lights, but crashes everything digital in the line of fire.

The standard defense today: pile on capacitors and inductors down closer to the load. Or, if the power levels warrant it, an AMSC D-SMES and powerchips. But when the interruptions are short enough, and the loads small enough, smart switching alone can solve the problem. The trick is to build a box that’s smart and fast enough to draw more current at the intake when voltage drops, and instantaneously recreate the proper output voltage and current at the outlet.

Soft Switching builds it. Their president, Deepak Divan, left academe in 1995 to found a company based entirely on this simple but hugely powerful idea. The company’s leading product today is its Dynamic Sage Corrector (DySC).

It’s built around powerchips supplied by Semicron, Toshiba, and Eupec; it can handle from 1.5 to 2,000 kW, and in size, it runs from about shoe box to commercial refrigerator (tiny in the world of big power). On the strength of superfast, supersmart switching alone, the DySC can smooth out the most common voltage sags - sags of up to 50 percent voltage deficit, lasting up to 15 cycles (1/4 second). Add a modest bank of capacitors, and the DySC can ride out 3 cycles of 100 percent voltage sags.

Functionally, the DySC power electronics replace or at least greatly extend the lives of less exotic ride-through technologies like batteries and flywheels. At the margin, it can compete directly against them.

In addition to its direct sales to companies like General Motors, Ford, Lucent and International Rectifier, SST manufactures the DySC as an OEM product sold through Square D, a large supplier of conventional high-power switches. SST also has an operating relationship with Asian Electronics Limited (India), where SST is establishing a wholly-owned subsidiary to manufacture products for shipment to U.S. markets. SST is also in discussions with Invensys (INVSY), a major UPS supplier. The DySC is already priced below the old analog solutions (which center on huge, slothlike, analog inductors). And the oldguard technologies have already bottomed-out on their cost curves. The costs of SST’s powerchips, by contrast, have only just begun to fall - and they’re going to fall as far as silicon generally falls, which is pretty close to forever.

ABB

What do sub-sea oil production platforms, pharmaceutical companies, food processors, pulp & paper mills, chemicals, airports, and dot-coms all have in common? A 10 MW substation, engineered by ABB. When the CBOT went down in Chicago, Commonwealth Edison called on the best in the business, ABB again, to reengineer and rebuild - and on a panic, seven-month deadline. ABB delivered. It built one new 200 MVA 138/12.47 kV substation from scratch, and refurbished four others, largely by modifying switchgear/breaker configurations.

The $25 billion-a-year ABB is both the world’s leading manufacturer of many substation components and the leading integrator of complete substation solutions. ABB also owns the power industry’s only counterpart to Bell Labs - a $2 billion/year (8 percent of ABB’s revenues!) research operation headquartered in Baden-Dättwil, Switzerland, with additional facilities in seven other countries, including the United States. ABB now ranks as the world’s leading developer of grid hardware, and the owner of the most sophisticated software assets required to add logic intelligently to high-power grids. Headed up by Randy Schrieber, VP in Raleigh, NC, the company’s U.S. Power Distribution group handles city-level grid operations. Over the next decade, this group will emerge as the leading provider of logic gates to the U.S. grid.

ABB’s component technology begins with the most basic - the high-power powerchip. ABB’s proprietary 1 MW monster IGCT single-wafer powerchips are aimed squarely at the power levels typically encountered in the distribution layers of the grid. And with the opening of a new fab plant in Lenzburg, Switzerland last spring, ABB has significantly expanded its powerchip manufacturing capabilities. ABB also has retained a stake in lower power powerchips through its large institutional holding in IXYS (SYXI) (April DPR).

One step above powerchips, ABB manufactures powerchip modules. The company is a major player in the Navy Power Electronics Building Block, PEBB, program (April DPR); ABB expects to release a commercial PEBB within the next year or so. The unit will be capable of serving as a building-level super-UPS at the front end of Powercosm hotels. ABB already has pilot customers in a Mid-West plastics manufacturer, and in a university that found itself being "UPSed to death," in Schrieber’s words.

ABB also manufactures a wide range of more conventional substation components. It is the largest transformer manufacturer in the world ($2 billion in sales). It manufactures sealed, gas-insulated switchgear that has a dramatically smaller footprint (it cuts a high-voltage 10- foot connection down to 10 inches) and is a lot more reliable than the conventional air-insulated alternatives. ABB also makes surge arresters, generator circuit breakers, advanced converters, and control technologies.

Finally, ABB is the world’s leading provider of turnkey substation analysis and rebuilding. ABB now offers customers Dell-like capabilities to build-your-own personal substation on an ABB website. This takes some doing.

The dynamics of massive current flows through long wires and nodal equipment are very complex indeed - as complex as the dynamics of a jumbo jet - which, as it happens, processes about as much thrust power under its wings as a typical substation conveys through its transformers and wires. About half the cost of building a traditional substation lies in the components themselves; the other half in the engineering and construction. ABB does both.

Extremely sophisticated modeling allows ABB to optimize the delivery of 9s to any customer at any node. The software dynamically analyzes the surrounding grid, its wires, switches, and transformers, assigning to each a probability of failure, duration of outage, and a time-torepair horizon. And on that basis, it searches out optimal equipment configurations within the constraints imposed by the surrounding grid, the customer’s needs, the utility’s budget, and a host of other factors. Footprint is one of them. As it did in Chicago, ABB can configure systems small enough to go inside commercial buildings. Much of the footprint reduction in Chicago came from applying logic, software and controls to existing components.

Until quite recently, ABB was vertically integrated from big turbines down to low-power switches. But it has recently shed about one-third of its operations (accounting for $10 billion-a-year in annual revenues).

Today half of its six business segments, and some 60 percent of its revenues, are anchored in core technologies of the Powercosm. Another 25 precent come from electric technologies for commercial buildings (circuit breakers, control panels, fuse gear, switches and so on) that will increasingly come to be centered in powerchips and the Powercosm. The remainder of ABB’s business lies in the enabling technologies for the oil and gas industries, a tiny share in renewable energy (politically very important in Europe), and a modest (by GE standards) $1 billion financial services account. Among the businesses recently shed are: refrigeration, rod and wire operations, rail operations, and heavy turbines.

ABB did, however, recently launch a microturbine - the TURBEC single shaft, oil bearing, 100 kW unit, a joint venture with Volvo Aerospace.

ABB’s traditional focus has been outside the United States. But ABB is a global company, and it clearly recognizes the ascendancy of the U.S. Powercosm market. Its Raleigh-based operations, and pending NYSE listing testify to that. We suspect it has a significant U.S. acquisition or joint-venture in the works. In the enormously complex and expensive challenge of adding intelligence to the power grid, ABB now ranks as the clear technology leader worldwide.

This is the company that brings together and knows how to integrate powerchips, power switches, smartchips and software. Judge it, too, by its technology alumni: Ake Almgrem of Capstone (July DPR) and Jerry Lietman of FuelCell Energy (September DPR). Look to ABB to announce several breakthrough power products at the time of its NYSE listing a month or two from now.

Gates in the Grid

The grid will get more gates. It will get smarter. Utilities know what must be done, and have the resources to do it; given some reasonable certainty of cost recovery, they are perfectly willing to invest them. The best among them are eager to - eager to push 9s down the grid, toward the multiplying number of griddependent digital users, who need more 9s, but can’t realistically embark on supplying them to themselves.

Regulators won’t stand in the way: to the contrary, they are already clamoring for the upgrades. Environmental activists won’t block things either. Some will merely stand aside; other will even applaud increasing the intelligence of the grid at substation nodes, because electrical efficiency of the grid can be improved, with much of the work occurring on brownfield urban sites.

At the most fundamental level, AMSC and ABB are in the business of caching power and switching it intelligently. And they know how to cache and switch it better than anyone else. Intel works with nanometers and microwatts. AMSC and ABB, with kilometers and megawatts. Ceramics for bits and ceramics for electrons. Gates on a chip and gates on the grid. Same business, really. Just twelve orders of magnitude apart on the power curve.

Gates in the Grid

American Superconductor

In the bit networks, copper gave way to ultra-pure erbium-doped glass. In the electron networks, copper will give way to ultra-pure bismuth-strontium-calciumcopper oxide ("bisco"). Two quantum-physical ceramics, one for the Telecosm, a second for the Powercosm.

American Superconductor (AMSC) manufactures bisco and builds things with it. "Superconductor" brings to mind long wires, but the main use for AMSC’s wires is in substation components. Among other things, AMSC builds wave-suppressing devices. Big devices, for grid-scale waves.

AMSC’s principal customers are utilities, along with large Powercosm customers that have megawatt-scale loads. Both are now using AMSC’s technology to push their power control nodes into the twenty-first century.

Where the electrical inertia of the grid is the problem, a countervailing electrical inertia in the substation is the solution. AMSC makes the SMES (or D-SMES), the (Distributed) Superconducting Magnetic Energy Storage unit. A semi-tractor trailer houses the superconducting coil, the liquid nitrogen cooling system, and power electronics.

What is it? It’s a huge inductor, the electrical equivalent of a flywheel, a "virtual generator" that is pumped full of power when the grid is up, and that almost instantaneously pumps back huge amounts of power, for very short intervals, whenever grid power abruptly dips. Suitably controlled, a D-SMES cancels out junk on the wires in much the same way as an active noise cancellation system cancels out noise in a helicopter pilot’s headphones - by supplying anti-noise. The only difference is that AMSC works with megawatts, not watts. Last July, AMSC deployed six DSMES units at substations along Wisconsin Public Service’s 200-mile Northern Transmission Loop, their first utility SMES deployment. The company has already supplied similar fixes to a number of industrial customers, as well, including the Tinker Air Force Base in Oklahoma and a plastics factory in North Carolina.

A few months after AMSC’s arrival on our Power Panel, General Electric (GE) signed up as the exclusive U.S. distributor for the D-SMES. Last month GE announced the first commercial order for a D-SMES - a sale to Entergy, a $9 billion utility based in New Orleans, that owns 15,500 miles of high voltage transmission lines and 1,450 substations. Other utilities will follow. One by one, at first. And then, as they grow weary of losing digital customers and being denounced for their "third-world" engineering, the herd will thunder.

A massive, super-fast, energy-storage device requires power electronics to synchronize its anti-noise to the grid’s noise. That takes some doing. From the get-go, the SMES is a DC storage device; the grid requires precisely timed AC.

Through a longstanding collaboration with Integrated Electronics, AMSC has developed solid-state power converters that can bridge that divide - converters capable of switching megawatts of power in microseconds. These extremely fast, high-power units are built around insulated gate bi-polar transistors (IGBTs) and the integrated gate commutated thyristor (IGCTs) (see April DPR). Last June, AMSC acquired Integrated Electronics outright.

Founded in 1996, Integrated Electronics specializes in industrial-level power converters, cramming them on to printed circuit boards, rather than in hand-built boxes.

The most powerful circuit-board inverters in 1996 handled 15 kW. Within a year, IE released a 100 kW unit using a proprietary printed-circuit board; today its modules handle up to 1,000 kW. The converter modules can be stacked in Lego block-like arrays to handle 10 MW and beyond. Employing a Motorola PowerPC for logic, and fiber-optic serial communications for synchronization, IE software can reprogram and reconfigure a module array for a wide variety of different applications.

An enormous market for these units is now just beginning to unfold. AMSC plans to start shipping powerchiponly trailers to add control, conditioning and intelligence to grid nodes. For every node that needs switches and a bucket of electrons, many, many more need switches alone. The dominant solution to grid transients today is to over-engineer everything - just keep the bathtub a good bit less than full, in other words. But with the right storage and switching technologies in substations, utilities can run the wires a lot closer to full capacity. For that reason alone, we consider it inevitable that high-power, solid-state silicon will progressively take over all grid switching functions.

Not overnight - nothing in this gargantuan business happens overnight. Just step by inexorable step, as the market gradually discovers what this new generation of silicon technology can do.

AMSC’s high-end powerchip control systems will also find applications in high-power private "grids" of every description: in big industrial motor drives, UPSs, flywheels, big fuel cell arrays (FuelCell Energy’s 3 MW systems, for example), or RAID-like arrays of Capstone microturbines, as well as electric cars, trains and trucks. (Caterpillar’s building-sized mining trucks are silicon-controlled, electricpower plants on wheels - an on-board diesel generator produces the electricity; electric motors turn the wheels.) Finally, AMSC is the leading supplier of superconducting wires for power cables themselves. Many cities already lack sufficient space in their underground ducts to place enough conventional wires to handle the ascending loads of the digital economy. Combine a bad transient with a peak load, and cables overheat, transformers blow, and iron manhole covers pop into the air like tiddlywinks.

Working with its Italian partner, Pirelli Cables and Systems (the world’s largest manufacturer of power cables) AMSC is now offering the most straightforward and economical solution: much more power in much less space.

Detroit, for example, experienced a blackout this past June because of a failed substation tie-line. AMSC is currently deploying the first-ever commercial superconducting cable - a 400 foot run with a 100 MW capacity - at Detroit Edison’s Frisbie substation. Some 18,000 pounds of copper in nine cables will give way to three cables, with just 900 pounds of AMSC’s superconducting wire contained in cables manufactured by Pirelli. This will free up six ducts for still more electric power, or perhaps, more digital power in glass fibers.

The AMSC/Pirelli cable is already cost competitive, and costs have nowhere to go but down. AMSC’s CEO, Greg Yurek (a long-ago MIT professor), is now happy to report that demand for bisco wire exceeds supply. AMSC can produce 500 km/year today, and it has broken ground for the world’s first commercial superconducting-wire fab plant designed to churn out 10,000 km of wire per year by 2002. Pilot production should begin in a year and commercialization a few years after. AMSC has over 250 U.S. patents, and an equal number internationally - a deep, Corning-like moat of intellectual property around its technology fortress.

When he dares to draw the inevitable analogy between bit and electron ceramics, Yurek does so only with professorial reticence and understatement. So he should - the whole superconductivity field has suffered from a decade of excessive media hype, failed forecasts, and commercial vaporware. There will undoubtedly be more of the same.

But AMSC’s technology is real - real enough for GE to put its carefully guarded nameplate on the side of the AMSC trailer. Ceramics will rule the Powercosm as certainly and inevitably as glass came to rule the Telecosm.

Gates in the Grid

The Personal Substation

How do you make a smarter grid? Much the same way as you make a smarter Web, or a smarter microprocessor.Build more gates, and make them faster. Cache power near the loads. Create more links between the nodes themselves.

The first step in pushing the K-9 grid to higher 9s is to install your own, best-available-technology substation - your "personal substation," so to speak. Which is perfectly practical, if you’re big enough. AOL is. Its newest campus in Prince William County, Virginia, is home to 60,000 servers. AOL’s dedicated substation takes two separate 115 kV high-voltage feeds from the grid, steps the voltage down to 24 kV through redundant transformers, and feeds the power to two 25 kV sets of switchgear.

If either of the two primary grid feeds fail, the substation turns to power from a thirteen-unit string of 2 MW Cat diesels, sitting on five days of fuel oil. Company-wide, AOL has 55 MW of its own back-up capacity at its current facilities, with 29 MW destined for facilities under construction - each one with its personal substation.

Multi-megawatt private substations sprout up at fab plants for smart chips [Intel (INTC)] and powerchips [International Rectifier (IRF)], server manufacturers [Sun Microsystems, and Hewlett Packard (HP)], software factories [Oracle and Microsoft (MFST)], and information servers (AOL and NASDAQ). Oracle operates its own $6.6, million, 13 MW substation in Redwood Shores, CA. It’s connected to a 60 kV feed, and distributes power to buildings on a 21 kV campus bus. Additional transformers (lower-tier substations) in each building take it from there.

Substations appear wherever servers, RAIDs, and routers accumulate. Some 30 million square feet of Exodus and AOL-level data hotels are now scheduled for completion in the next eighteen months. The increasingly common 200,000 sq ft facility is a 20 MW load. Every such node added to the Web will add a matching substation to the grid.

Utilities themselves often locate their own substations on the doorstep of large loads, from airports to refineries, and hospitals to hotels, because a direct link between high voltage lines and the large customer at the feeder is the best way to provide the power required. A substation linked to two separate points on the grid, as AOL’s does, increases reliability too. But important though they are, large private customers represent only the leading edge of the substation boom. Utilities need more substations to improve overall grid reliability for everyone else. By building more substations, utilities shrink the footprint - i.e. reduce the number of customers affected - by the common sources of spikes, dips, short-circuits, and meltdowns. More substations create more points at which to interconnect independent parts of the grid, so that distant transmission lines and power plants effectively back each other up.

Finally, substations must proliferate to accommodate the many competing suppliers of wholesale electrons that want grid access. Utilities have been ordered to interconnect with independent power producers, and sister utilities.

Well over one half of all electricity produced is now sold several times through broker contracts (the new wholesale, competitive kWh commodity market). The MCI’s (WCOM) and Sprints (PCS) of new power - the likes of Enron (ENE) and Calpine (CPN) - are now congregating around the old Bell System of the power grid, and clamoring for open access and non-discriminatory interconnection.

So there will be more substations, as certainly and inevitably as there will be more corporate suppliers of power, more generators pumping electrons into the grid, and more large loads drawing them out. Better substations, too. If they are slow, stupid, and fragile - as they still are, for the most part - substations add high-frequency noise in the process of subtracting lowfrequency noise. But technology now at hand allows them to be smart, fast, and robust enough to subtract noise (and thus raise 9s) across the board.

Gates in the Grid

It’s a clear day in Silicon Valley. We’re on Sun   Microsystems’ (SUNW) sprawling corporate campus. Why is the air around us literally humming? That’s the sound of electrons, as they pulse through the five main megawatt-level transformers - truck-sized gray   boxes of copper wire. The transformers are arrayed in Sun’s tennis-court sized personal substation. This is where two feeds from PG&E’s 12.47 kV grid interface with Sun’s in-building power system, which   lights tens of thousands of SPARC CPUs inside the row upon row of Sun Enterprise 10,000-class servers and StorEdge RAIDs beyond.

The substation is where logic is added to the grid. And where electrical noise (or worse) is added also, in a bad substation - or subtracted, in a good one. Essential though they are, the wires embody the grid’s stupidity. Its intelligence, such as it is, resides in its nodes, in its substations and switches. Like gates on a microprocessor, those are the decision points, the places where intelligent choice occurs, if it is going to occur at all. Much of the break-down of order and the collapse of power happens here too. At 1:00 p.m. on August 12, 1999, cooling equipment failed in a substation serving the Loop in Chicago, and a transformer overheated. Then a 1950s-vintage plastic sleeve used to splice cables at the substation fried. That was it for power in the Loop. The Mercantile Exchange and Chicago Board of Trade (CBOT) crashed. Every last soul in the pit had to stop trading. Bulls, Bears, and Hogs, pork bellies, soy beans, and even bulk electricity. It took Commonwealth Edison 90 minutes to restore power to the financial district, and another ten hours for most other customers. Some 100,000 others were powerless for three days, while summer temperatures hovered in the 100s.

U.S. spending on "transmission and distribution" fell between 1990 and 1995; it has been on the rise since. It will hit $12 billion this year, and rise sharply from there on out. The political and regulatory stars are now aligned with the market and technology imperatives - something that doesn’t happen often in any business related to utilities. A big share of the new spending will go into faster, smaller, smarter switches and substations. By shrinking the existing components, the architects of the new substations will make room for thousands of new ultra-low-emission 15 to 60 MW gas-fired turbines, distributed and deployed closer to the loads to sharply improve grid reliability. The October companion issue (Heavy-Iron Lite) addresses that half of the story. This issue is about switches and substations - the logic gates in the grid.

American Superconductor (AMSC), which we placed on our Power Panel a year ago, is one of the leading manufacturers of local-area grid and sub-station level superconducting wires and components. It is now joined by the Swiss ABB (Asea Brown Boveri, global headquarters in Zurich, Switzerland; U.S. headquarters in Norwalk, Connecticut). ABB is a global leader in the manufacture of substation components, grid operations, and the contract design and engineering of entire substations. ABB is planning a U.S. listing on the NYSE later this year.

The K-9 Grid

So America has "the grid of a third-world nation"? The Secretary of Energy said so recently. That’s nonsense, of course, as anyone who has actually been to the third world knows. America has a first-world grid, a twentieth-century grid. What we need, however, is a twenty-first-century grid. The grid has kept pace with motors and light bulbs. It hasn’t kept pace with microprocessors and lasers.

In "The Powerchip Paradigm", our inaugural issue of a year ago, we described the widening gap between the quality of power supplied by the grid, and the quality required by the digital infrastructure. The digital economy requires power that’s up 99.9999 percent (and better) of the time, power that’s rock steady, from milliseconds to days to years. The old grid typically manages about three 9s - 99.9% up time, with interruptions ranging from fractions of a second to fractions of a day. Call it the "K-9" grid. By digital-economy standards, it’s a dog.

No matter what utilities spend, the grid alone will never be good enough for the AOLs (AOL), Ciscos (CSCO), Suns, and Oracles (ORCL), the Powercosm hotels and the server farms. Long, shared wires just can’t be made that reliable. But to say so is to miss the point.

Every last factory, store and home is going digital. Every one will demand power more reliable than it’s getting today. But most won’t need power as good as Oracle’s.Millions of smaller customers aren’t going to install their own turbine or ride-through flywheel any time soon. But neither will they tolerate the canine grid any longer.The opportunity now is for those who have the technology to build its new, high-9s successor. In last month’s mailing we included "Goodbye To The Grid", the September issue of our sister Gilder publication, New Economy Watch.

Make that "Goodbye to the 20th-century Grid". In the months after its CBOT-crashing outage, ComEd spent $1.5 billion upgrading its local transmission and distribution facilities in Chicago - over $100 million of which was used by ABB to build one new 200 MW substation and upgrade four others with new transformers and switchgear. For the next decade, utilities and large private users across the country will be investing massively in similar rebuilds.

The grid, to most people, suggests wires. And it certainly does have wires. Some 680,000 miles of long-haul copper and aluminum backbone supply high-voltage (230 to 765 kV) transmission; another 2.5 million miles of local wires (generally under 170 kV) supply distribution.Measured by route miles and physical footprint, it’s (by far) the largest network on the planet. Distribution plant alone accounts for about half of a typical utility’s investment.

In the dumbest possible configuration, it’s just wires, nothing more. Power is generated at the top, consumed at the bottom, and transported in between by a passive, unswitched, trunk-and-branch network. This was the structure of the very first grid, from Edison’s Pearl Street, NY station in 1882. In that architecture, there is no possibility of making dynamic choices among alternative transmission lines, feeders, or generators; the most the nodes can do is shut off power to one or more of the branches down the line.The higher up things fail, the more widely the failure is felt.

Overall, the local distribution network is responsible for over 80 percent of the power quality problems experienced by the typical customer. Lightning, weather, "carpole interactions," and "suicidal squirrels" all cause their share of trouble. So do customers themselves, when they abruptly add or subtract loads, whether from an arc welder firing up, or a server farm lighting-up. But the sheer physical bulk of the wires is really the biggest problem.

The grid’s wires store power in the electric and magnetic fields that surround them - huge amounts of power, because the wires are so long, and carry so much current.Whenever loads or supplies change quickly at the ends, the electrical inertia of the wires (their capacitance and inductance) knocks the grid’s voltage and current out of phase.

Grid engineers call this reactive power: from where they stand, the wires appear to contain malignant generators of their own, that send huge amounts of rogue power sloshing up and down the system, like waves in a bathtub moving water independently of the faucet and drain.

The substation - "sub" to the power plant, the prime mover of the electrons - is where the grid engineer tries to re-impose law and order, and other things besides. It is typically a high-fenced plot of land, about the size of a tennis court or football field, filled with arrays of car- and or even house-sized transformers, ten-foot-high ceramic insulators (they look like wavy pillars of soft ice cream), and massive spring actuated circuit breakers. The 100 largest utilities have some 7,000 bulk power substations; there are well over 100,000 lower-tier substations.Here, power flows are switched, combined, or rerouted.Here, voltage is stepped up or down. And here, logic is added, and electrical noise is - or at least in theory, can be, and should be - subtracted. At the very least, a substation will cut off power (temporarily or permanently) when a line gets short-circuited downstream, or when the substation is directed to implement a rolling blackout. If the substation has a second source of power - from a second, independent high-tension trunk, for example, or from a back-up generator situated at the substation itself - then the substation can contain still more logic, and be called upon to make more complex logical choices.

The grid already has multiple points of interconnection at the top, at key crossroads on the transmission grid, and lower down, among trunks, feeder lines, and distribution wires. It all appears, at first blush, to be quite a web of complementary pathways and smartly designed redundancy. And so it is, by the standards established to serve refrigerators, motors, and light bulbs. For traditional requirements, the substations perform quite adequately. They represent relatively cheap, robust, tried-and-true technology. But as often as not they degrade power to chip-crashing levels, even as they scramble to do the right thing for refrigerators and light bulbs. Existing substations switch power almost entirely with crude (by digital standards) electromechanical switches and even cruder circuit breakers.

They deal with reactive power and other electrical transients by means of huge, baffle-like analog capacitors or inductors, and by dissipating the reactive power as heat in the lines themselves. They add high-frequency electrical noise even as they strain to suppress lower frequency outages. And - far too often - they just can’t handle the reactive-power transients at all - so when things get bad enough, they blow up instead. Substation transformers are the most common casualties; switches rank second. In the best of circumstances, the substation’s thrashing doesn’t quite fry your GE refrigerator or Dell PC. In the worst, it halts trading at the CBOT.

The traditional utility solution: fill the tub only half full, hope for the best, assume the refrigerator can handle the noise, and let the digital economy take care of itself. Traditional - but no longer acceptable.

Congratulations to Tyler smiley

May I also point out he is missing from the list of The Pack/Tribe from both US and European sites.

I take a deep bow to Tyler for having the "balls" to chose this name.

With names like Porn Star Dog, C-Sleazy Dog, C-Psycho Bitch, and now C-Dirty Dog,  it is becoming increasingly difficult to think up new and outrageous tribe names.  grin grin grin

Hey all,

Just so everyone knows...this thread is NOT the official list of fighters.   The official list can be found here:

http://www.dogbrothers.com/adobedocs/registered-fighters.doc

If your name isn't on it, I haven't rec'd your figther form.   We need fighter registration forms for every fighter.

Thanks!
Cindy

P.S.  Just picked up mail and just updated it...

The list above has been updated.  As I said above, if you are not on this list, your're not registered.  smiley

William Lundin
Boo Dog

The first person (William) made it on the list, but Boo Dog did not.  As oversight, or will he not be fighting ?

I updated “the Pack” on my website. Dear members of the tribe, could you have a check at the list, and please let my know if you find somebody who is not correct listed…

Wuff
Guro Benjamin “Lonely Dog”

The following also may need to be corrected:

Poi Dog is listed twice - once as
  Kalani “Poi Dog”
and then as
  Roan "Poi Dog" Grimm

Tennesse Dog's last name is missing, and according to this posting, it should be Bryant

Dog Lorenz Glaza is missing (see this post here)

A yip to new friend Thomas, a man of varied background who brought some very exciting 3 section staff from Praying Mantis to bear!

Yes, an interesting person, and capable practitioner.  I saw part of the fight, without realizing it was him.  He handles the 3-section staff with considerable dexterity.  Hope to see him again, in the future.
