			<description><![CDATA[Like frugal blogs, making money related blogs have become insanely popular since the global economy has declined in recent years. The want for making more money in order to have a “Ok” quality of life, is increasing year on year. Wages are not rising, jobs are becoming less secure and the cost of living is constantly rising. This is why sites like the ones below in this section are becoming more and more popular. My blog post - website dust grooves: https://dustandgrooves.blogspot.com]]></description>

			<description><![CDATA[The name is fitting. Great piece Michael. I think the reason you don't see it on some nights is the air is more humid on those evenings. Static electricity works better in a dry environment. The reason it is not seen on the ground is the craft is "grounded" better than when in the sky. Keep up the good work!]]></description>

			<description><![CDATA[Wonderful article Michael. Really moving. On a much lighter note, when I served in the 2/505PIR, we used to sling load HMMWV's with Chinooks. It was a ritual of sorts to have the new guy (myself included) hook the sling to the helicopter while a more veteran soldier was supposed to ground it first.... supposed to. Looking back, I can't believe we'd send that kind of voltage through a kid as a joke - although it still makes me chuckle to see a guy get thrown from the top of a HMMWV because his "buddy" didn't ground the hook.]]></description>

			<description><![CDATA[""Basically it is a result of static electricity created by friction as materials of dissimilar material strike against each other. In this case titanium/nickel blades moving through the air and dust. It occurs on the ground as well, but you don't usually see it as much unless the aircraft is landing or taking off. *** The most common time is when fuel is being pumped.*** When large tankers are being fueled they must be grounded to prevent static electricity from discharging and creating explosions."" Static electricity is not a function of friction, (friction is mechanical) it is a result of proximity of electrical charges in insulators. Static electricity is built up even when there is no friction between bodies, it is an electrostatic effect (Coloumbs experiments). The fact that the effect is seen consistently when the chopper is grounded to the Earth proves the energy for the luminious discharge is from the ground, not the blades. The blades are stirring up relative motion of sand against the ground, separated by several feet of chopper, that motion can generate massive charges. The lower part of the chopper is a giant electrical conductor to bridge the gap between the sand layer and the ground. A crude electrical analogy is a capacitor, electrical energy stored in an insulator between two conductive plates, except a capacitor stores free electrons in/from conductors, and static is a pheonomenon in electrical insulators. Light is photon emission when an atom's electron changes state from high to low. The eletrical energy is apparently from the ground, up (or down) through the choppers metal parts, through the blades (Ti is a conductor) and discharging against the sand cloud. The chopper conducts excess charge to the blade tip/edge where it arcs over to the swirling sand, with a light discharge. Piezoelectric effect would not take into account the fact that the effect is much more pronounced when the craft is grounded. It is purely within the (crystallaine structure) when mechanically distorted.]]></description>

			<description><![CDATA[I've run a literature search on the research publications and there's no work done on the subject, which is remarkable in and of itself - there is some work on fixed wing aircraft and static discharge, but nothing else. I'd be curious to know what the engine mechanics have to clean out of the hot sections in the turbines, as this stuff often melts to glass there. The phenomena isn't St. Elmo's fire - that will accumulate at discharge points etc. (pitot tubes and the like) as well as rotor blades. This phenomenon has been noted among helo pilots for some time and speculation has it as some kind of piezoelectric discharge (caused by impact with the quartz sand) that mimics the von Guericke effect by creating static discharge from the quartz structure that's carried into the airframe. The sparkling effect is primarily from the static discharge wicks at the rotor tips. In other operational areas, this has been noted in operations over high-quartz sand and concrete which gives anecdotal support to the piezoelectric theory. http://www.iop.org/EJ/abstract/0022-3719/12/17/012 Triboluminescen ce is likely a byproduct of piezoelectricit y, and the differences don't matter here since the article was really about the loss of fine young men set against the fireworks of sand and motion.]]></description>

			<description><![CDATA[This effect seems to me to be certainly a Triboluminesenc e effect. The term derives from the same root as the word "tribulation", meaning to trouble, abuse or disturb. In this case sand grains suspended in the air are "troubled" by being struck by the whirling rotors, causing the emission of a cloud of photons, which appear as "sparks" on the photos. The photos which show continuous "streaks" probably represent a condition where the "sparkles" exceed the resolution limits of the photosystem. This is not the same nor related to the throwing of sparks from-say-a grinding wheel which is a chemical effect. The effect has been known for a long time--I have seen examples in the 1950's, using the same terminology, although the context was, of course, different. The photos are extremely good, and could serve as textbook examples. Someone mentioned Titanium-nickel as a participant in the transaction--"I n my day" the rotors were more likely Sitka spruce.l Congrats to the photog--and best of luck to those who must fly the aircraft in what must be rather nasty conditions., K.

			<description><![CDATA[As a current pilot of one of the Pedros from your "Voter" article, the descriptions from PhilMB and CathiL sound most accurate. They are also correct that this is not St. Elmo's Fire. Although I have not yet been to the desert (departing in the spring), stories of the blade-erosion and resulting "show of sparks" caused by the rocky dust/dirt are well documented in our community. Believe it or not, it can be bright enough to degrade the performance of NVGs under certain conditions. Regardless, I have never heard a specific name for it and I will begin to use the Kopp-Etchells Effect in hopes that it will spread, at least among Air Force helo guys. Best of luck!]]></description>

			<description><![CDATA[The effect can't be completely piezoelectric because it dissipates when the helo's ramp is dropped. The ramp acts as a giant grounding (earthing for you in the UK) rod. Regardless, from today on, it's the Kopp-Etchells effect. As an aside, you haven't lived until you've seen a baby Second Lieutenant decide things aren't moving fast enough during a sling load operation and grab the hook with a bare hand. A secondary presentation of the Kopp-Etchells effect can be seen when the young officer's eyes go wide, his hair stands up and he makes a sound something like, "SHEEIIIGGGGGUU UBBBBBBUUUUBBBB UUUUUUBBBBB!" It keeps happening and it's never going to get old. New year is coming up and I'm going to launch a few rockets for Etch and Koop. They and the others on the list have gone into my memorial and get a shot lifted when ever I get a chance. Thank you, Michael]]></description>

			<description><![CDATA[After waiting for the tears to stop, I wanted to add a bit. The effect seen is very probably from little bits of quartz crystals in the dust getting hit by the rotor blades. When piezoelectric crystals deform they release very high voltage jolts of electricity. Piezoelectric quartz is very common. Michael yon is an incredible human being. I wish I had the nads to go where he goes. Keep the picture sharp on our boys & girls Michael, we are buoyed up by your reports, even as we grieve for the losses.]]></description>

			<description><![CDATA[I had your article forwarded to me and am very glad I took the time to read it. I flew UH-60's for years in the U.S. Army and have experienced the halo effect many times when doing night operations. It is particularly vivid when using a night vision device but can also be seen with the naked eye. I would often gaze at it with wonder when a number of aircraft were in line in front of me and there were numerous glowing rings. It is quite a sight. To answer an earlier post, yes, it also happens with single rotor helicopters. I remember hearing it called St. Elmo's Fire and also the piezoelectric effect but am fully behind the fitting name change proposed by you. To suggest a respectful and memorializing name to a building, a park, or in this case a common yet largely unknown effect is honorable. Thank you. And to all those who are spending many days of their lives fighting, and sometimes dying for the freedoms, dignity and lives of others, THANK YOU.]]></description>

			<description><![CDATA[My brother teaches physics at a science & technology high school in the Washington, DC, area, and has received numerous awards for his work on science journals and teaching physics. I wrote to him about the Kopp-Etchells Effect and he agreed I could post his response: "Sure, you can quote me. One cannot know for sure without further testing and verification, but what I wrote would be my hypothesis (educated guess). I will ask my students this year if anyone wants to take this on as a research investigation." Here is his hypothesis: Hi Cathi, While it's useful to add additional nomenclature for a specific effect (e.g., Kopp-Etchells Effect for rotating helicopter blades in dust), it doesn't lead us to a complete explanation. These are amazing pictures, but I thought about a different effect given the nature of the sand crystals in the dust. Airplanes often accumulate electrostatic charge due to friction (triboelectric effect) as they move through the air or even due to static charge separated and accumulated by the air itself from rapid movement of wind (consider the spark that set off the fire in the Hindenburg disaster). This charge is usually dissipated at the sharpest points of the object where the electric fields are naturally highest (this is one reason we use lightning rods - sharp points to spray excess charge into the air). Most aircraft have such electrostatic charge dissipators built into their designs. If there were a buildup of charge beyond what the charge dissipation devices could handle then we would see sparks occurring from the tips of wings (or helicopter blades) as a coronal discharge or even a complete spark. It would look like miniature lightning or electrostatic glowing at the sharpest tips, but on the helicopter blade edges and tips. But these pictures seem to show a different effect. If you look closely, the glowing is not coming from the metal blades but from the dust itself. It exists in the dust AFTER the blade has passed. This would seem to suggest more of a piezo-electric effect. The piezo-electric effect occurs because crystals such as quartz (e.g., as found in sand and sand dust) are compressed from some kind of rapid impact (like being hit by a rapidly rotating helicopter blade) and cause excess electrostatic fields on the surface of each crystal, often thousands of volts, that can discharge right on the crystal. Piezo-electric crystals are today used in charcoal grill lighters and on most gas stove lighters. When you use a charcoal grill lighter you pull a trigger that slams an internal hammer against a crystal at the end of the lighter where a spark is generated to light the fumes coming from charcoal lighter fluid. From a blog in 2003: "Those aircraft are hovering, and those flashes of light are the sand particles emitting bright glows as they are disturbed. It is the piezoelectric effect, where a crystal makes a big energy shift when its crystal lattice is mechanically disturbed. This is the way a diamond record needle drives the sound into the amplifier. The goggles amplify about 40,000 times, so these very dim glows look like sparks. As an experiment, get fully dark adapted, then smash a sugar cube with a hammer. The glow is a shocking green!" (NickLappos, 27th April 2003, 05:25) The blog continued with one person suggesting that the effect may be caused by burning bits of metal being emitted by the helicopter blades like grinding metal from a high speed sander. But I think that those bits of metal would be thrown off the wings outward. These glowing particles seem to stay in place as the blade passes. Bob If you are interested, I'll let you know if a student does take him up on this and what the results are. Thank you for all you do, Michael!]]></description>

			<description><![CDATA[for Thomas Abella: I flew helos in Viet Nam for the Marine Corps. The idea of putting a tarp on the ground would never work. The downdraft under a landing Chinook is hurricane force winds. What you would get would be a disasterous crash as the tarp blows off the ground into the rotors. Better the halo effect and eroded rotor blades, which can be replaced.]]></description>

The Kopp-Etchelles halo is a fitting name as these two and your story helped me to get back up and start fighting again. Apathy is not allowed ! We need our Veterans to return home safely and run for the House and Senate to displace the morons. You all are the real leaders so please return safely home to us . We will help you continue the fight asking people to vote for the men and women that understand. God Bless you all!]]></description>

			<description><![CDATA[A friend whose son is an Army Ranger (he has served several tours in Afghanistan and elsewhere) sent me the funeral notice of Sgt. Alejandro Granado of Tatum, Texas. I think she tries to make sure that, while she knows she can't keep up with them all, the fallen heroes from our great state do not go unnoticed and their families and friends are not left feeling no one else mourns with them. We both signed his online memorial book; we both prayed for his family, as we do ALL our troops (joined by many others here in Galveston) and those of our allies. God protect and preserve you all; many blessings for your courage and dedication to duty. To you, Michael, thanks for keeping it immediate and real for us so that WE do not slack in our daily prayers. We help one another with reminders by email and such, but your reports bring home the urgency and necessity of undergirding our military men and women with the knowledge that they are constantly in the thoughts of many, and that they ARE appreciated. I linked to your blog from that of J.R. Rawles (www.survivalblog.com), a former soldier who also keeps many aware of what is going on underneath the distractions of politics and the economy. Best wishes and prayers are coming your way, too.]]></description>

			<description><![CDATA[Michael, I have family members that have fought in almost every major conflict, war, excursion, or whatever you want to call it, from Vietnam on back to the Revolution. I confess that even with such a family tree, I find myself on again and off again following the war, and remembering our service members. Even typing the word "war" it has a tiresome feel to it, and this concerns me. God be praised for brave young lads such as these, and their sacrifices, too numerous to record, all on our behalf. We homebound citizens must be fierce to remember them, and fierce to honor them when we see them at home. God help us.]]></description>

			<description><![CDATA[They are remembered by more than you might think. I live in Irvine, California where a grass roots group of citizens spontaneously crafted handmade memorial crosses in 2003 to honor the fallen Americans in Afghanistan and Iraq. For six years the number of crosses each bearing photographs, names, ranks, age, hometown and cause of death of the fallen heroes has increased. Each year my family and I attended the Memorial Day service to pay our respects; this year we decided to participate in the daily services from Memorial Day through July 5th. Each night a different group of people stopped by and helped replace and light 150 candles, one for each memorial. We had local citizens, but others came from several states and a handful of countries to pay their respects. It was common to see a veteran of the war on terror stop and quietly sit in front of a memorial and then leave. I can honestly say that it was among the most moving experiences of my life, to see the faces of all the fallen and hear their stories and honor them with the pledge of allegiance, a prayer and taps. The group of citizens is now working to create a permanent memorial on the same site that will have all the names etched in granite panels displayed in a beautiful setting. We hope to have it completed by next May. To read more about this effort go to www.northwoodmemorial.com and view the video about how it all started. If you wish to honor the fallen in your town, just do it. It doesn't require the government's permission or money, just gather a group of like minded neighbors and do it. Trust me you'll meet new friends and feel better for the effort. The testimonies of gratitude from the local Gold Star Families for remembering their children/siblin gs/parents will move you to tears.]]></description>

			<description><![CDATA[Michael - thank you for all your work and sacrifice. Might I respectfully ask if anyone has thought to have some sort of tarp placed on the ground before a helo comes in; this would reduce the dust considerably. In fact, in one of your photos a tarp is draped over other supplies. One of these could removed and placed in the landing zone to reduce dust-ups. Again, thanks very much for your continued bravery and thanks to the bravery of our fighting forces in Afghanistan.]]></description>

			<description><![CDATA[Michael, I was forwarded this e-mail by a friend. I was touched by the poignant way in which you spoke of our warriors. Some of us maintain a brotherhood which transcends national boundaries. It is a solemn duty to go into battle with the objective of taking another man's life. Yet at times it must be done in order to stop the wanton destruction of those whose only crime perhaps, is being in the way. Evil is not contained by words alone. Men of action and determination have to stand against the monstrous attempts of men without conscience who use terror deliberately in order to achieve their ends. Early on in human history God gave men the responsibility to restrain, by force if necessary, the actions of the few that threaten the safety of the many. In every conflict against oppression, the contest becomes this. Will force used for evil intent prevail, or will it be overcome by force used for good. Having been a warrior, I understand what happens in deadly clashes between armed men on the battlefield. Bloodshed is ugly. I have keenly felt the anguish at the loss of friends, and a brother in Vietnam. My son, the Marine, follows in my steps, three tours in Iraq, now soon to Afghanistan. Will I mourn him as we now mourn those who gave their lives so far in this present conflict? I do not know. But I will not weaken his resolve by selfish attempts to deter him from doing his duty to his country, to humanity and yes, to his God. Those who desire peace at any price are naive at best and cowardly at worst. I honor those brave souls who refuse to sit on the sidelines with those who pretend that all's well with the world as long as it doesn't touch them. I raised my son, with his siblings on the mission field of Paraguay, in order to let him see the crying needs of a weary world. And to inspire him not only to see it but to do something about it. I am proud of him, and of those like him. Thank you for your efforts to give balance to the one sided reporting. Thank you for your willingness to stand in harm's way to give us a much needed perspective. May He who loves the brave watch over you.]]></description>

It is great to see a journalist/repo rter talking about the human side of these soldiers. I thank each one of them not for me but for the willingness that each of them has to defend their friends in battle and their families as well. If not for this generation of heroes our children would have no one to look up to like I did with my grandfather and father from WW2 and Viet Nam. Stay safe Mr. Yon and keep up the good work.]]></description>

			<description><![CDATA[I have had nephews fight in Irag, and another three have completed tours in Afghanistan. I found out tonight after reading your article that a fourth is there now in harm's way. I regret that many people might see a cable headline or very small article about "4 soldiers killed in Helmand Province" and not realize these are real men and women. They are sons, daughters, fathers, mothers, sisters and brothers, each one leaves a gapping hole in the hearts of dozens of people. The same thing occurs as we too often give a fleeting curiosity to a local story about a tragic automobile accident. We forget that these are real people. You have a gift for helping the rest of us to understand that they are our neighbors, our family, and friends that are out there protecting not just those of us at home, but helping the innocent souls who live these war torn countires. When I read your posts such as this one, I come away with a better understanding of what "honor" truly means. Thank you for your work. I will be starting a new job soon, my first since being unemployed for the past 23 months. I promise you a cut from my first paycheck. Thank you again.]]></description>

			<description><![CDATA["Sgt Bill Cahir, USMC Michael, I was struck by your dispatch; the very first name that appears on your list, Sgt Bill Cahir, fell last week in Afghanistan. He was a member of 4th CAG and a 40 year old Marine Sgt. His brother was a classmate of mine at State College High School and Bill and I are alumni of Penn State University. Bill is the third soldier of the sea from PSU to die in combat since 9/11; the first two were Lt. Michael Murphy USN/SEAL and Captain Todd Seibert, USMC. Bill left journalism after 9/11 to enlist in the Marine Corps at 34. He deployed to Iraq, fought in Fallujah and ran unsucessfully in the most recent PA Democrat primary in Pennsylvania. He was on his 3rd combat tour and left behind a wife pregnant with twins. He will be laid to rest at Arlington sometime next week. Thanks for everything that you do. Semper Fidelis. Thank you for pointing out that when it comes to the dirty work for country, for NATO , where ever we are sent Often Marines and Navy are the closest of brothers. I owe my life to a couple of marines and a couple of them owe me but we neveer look at it that way. We just find a way no matter what to bring our own home. I can't carry two Boston phone books very far anymore but I can still swim deep and far. Thanks for the rememberance of our unity. CHase]]></description>

			<description><![CDATA[Michael, Kim and I spent time with Ben's family in the days before his mother made the decision to give him away. You will travel a very long distance and time to find another human being so full of love, life and grace as Jill. I was unable to attend the funeral at Arlington (was in Saudi Arabia), but Kim was there. Thanks for acknowedging CPL Kopp in the same way oyu do so many others. Jeff]]></description>

			<description><![CDATA[Michael, another dispatch that puts us on the dusty LZs of a country a world away, and moves us to carry the sadness of seeing fine men and women ground away by war. Thank you, friend, for connecting our hearts to them and helping us pause to embrace them across the miles, and into eternity. I bet your posts and pictures short out A LOT of keyboards. The copter pics are truly amazing, and the second to last especially so. You can almost see the cap and flowers left behind by the warrior heros. Maybe that's why they call them halo-copters. Stay safe, and keep shooting and posting.]]></description>

			<description><![CDATA[Michael, I have gotten your notes from a friend for a long time. I just wanted to tell you how much an old marine and Army guy respects your efforts. I will do what I can to continue to support our troops and our country and your efforts. Thanks]]></description>

			<description><![CDATA[Michael's chosen path to not only tell our Warrior's stories but to chronicle the battles and try and inform the world is something that few men in the history of the world have done and few have done as well as Michael Yon. Everyone who reads this needs to spread the word by email and by telling of Michael's Quest and Chronicles. Also everyone needs to remember that no one except his readers are supporting him. Everyone needs to encourage donations to Michael. I have not been able to give much through the years to Michael, but I have always considered it money well spent. I have two grandsons now in the Military, and one more chomping at the bit to become a United States Marine. So far my two who are serving are serving out of actual combat but that can change at any time and they stand ready to go. As previously stated, the vast majority of the world doesn't care about the wars or those that fight in them, even though without these men and women, sons and daughters, grandsons and granddaughters the world would be a very terrible place for all of them...and us. So, make it your personal responsibility to get the word out and help Michael tell his stories and present his pictures to the world. You know it is the right thing to do.

			<description><![CDATA[St. Elmo's Fire runs actinic-white to blue; whereas these exhibit the typical heating paradigm of a meteor, going red-orange-yell ow-white. I suspect it is more that the high-speed boundary layer of air on the rotors is creating dust particle meteor swarms as the particles are instantly heated to vaporization. I like Michael's name for it - the Kopp-Etchells Effect. And thank you Michael, for your travels in harm's way to provide us with a truthful and sobering view of this current conflagration. Please convey my thanks and prayers to them all, and that they safely return in glory.]]></description>

			<description><![CDATA[Michael, I was struck by your dispatch; the very first name that appears on your list, Sgt Bill Cahir, fell last week in Afghanistan. He was a member of 4th CAG and a 40 year old Marine Sgt. His brother was a classmate of mine at State College High School and Bill and I are alumni of Penn State University. Bill is the third soldier of the sea from PSU to die in combat since 9/11; the first two were Lt. Michael Murphy USN/SEAL and Captain Todd Seibert, USMC. Bill left journalism after 9/11 to enlist in the Marine Corps at 34. He deployed to Iraq, fought in Fallujah and ran unsucessfully in the most recent PA Democrat primary in Pennsylvania. He was on his 3rd combat tour and left behind a wife pregnant with twins. He will be laid to rest at Arlington sometime next week. Thanks for everything that you do. Semper Fidelis.]]></description>
