Energy Efficiency and Gravity

February 12th, 2010

Over the holidays, I went to Utah to do some ice climbing with a friend of mine. Ice climbing is like rock climbing yet on frozen waterfalls. Yes, water does freeze into water falls. Of course, in cold places. Here’s a picture of one of those climbs, The Fang, Provo Canyon, Utah, 400′ tall, pitch one of three:

Some of the climbs we did were 650′ tall, so imagine pulling yourself up an icicle for 650′ vertical feet. Now add in the cold, limited sunlight, snow, weather, changing ice conditions, and you can see the importance of moving quickly, AND EFFICIENTLY. After spending the majority of a day hiking into and climbing a large icicle, without much option to back out other than down climb (which is never fun), efficiency is paramount to preserving energy and moving quickly thru a climb. My point, efficiency is important everywhere in everything we do.

While I try to keep these blog topics focused on energy ,sustainability and data center topics, when something significant happens in ones life, it seems prudent to share it. This last weekend, I went ice climbing at Eagle Falls, which is a small ice climb near Emerald Bay, Lake Tahoe. I’ve climbed there several times before, led routes, set up top ropes, and everything else. Here is a picture of me climbing the cliff from years ago:

However, this Saturday was different. Following the one hour hike in, I arrived with my party of six and two other about equal-sized parties at the base of the climbs. With so many people to climb on a few routes, I rushed to lead a route up one of the steepest sections, setting up the route with ice screws, which my partner, Tony, would remove upon climbing up after me, and then we would establish the route as a top rope for others to use. Here is a picture of me on the route:_kcm86722_kcm86721

I quickly climbed up the 40-50′ cliff to the snowy ledge at top, which was very precarious to crest, proceeded up to a tree in which I was going to set up an anchor, upon which one of the other climbers (Blake) offered my use of his anchor already set up around the same tree. This anchor was ready to go, so I intended on clipping myself into it and belaying Tony from atop this snowy slope above the cliff.

As I sat about 15′ from the edge of the cliff, up a snowy slope, I tied in to protect myself while setting up an anchor system to protect me and Tony while he climbed. However, I rushed, and quickly put Tony on belay without properly tying myself in, doubling up the anchors into one system, and then double-checking it, as I would always do. I rushed because there were so many people at the climb, I wanted to be sure they all had time to climb. I rushed on their behalf but certainly not at their request, while not-fully completing my own safety check list. I goofed, and I goofed big. I realized the error as Tony had already climbed for a few minutes, and, since he couldn’t hear me nor we could see each other, and stopping his climbing to down climb was dangerous for him, I asked Joe, who had just reached the area atop the cliff where I was via a different ice route, to use a rope I had to tie around a tree and bring it to me to clip into my harness while I belayed Tony, keeping him safe and me from getting pulled off the cliff should he fall. I also dug the heels of my crampons further into the snow, creating an alpine-style anchor with my body in the fresh snow in case needed, hoping it would be enough to hold Tony should he take a fall.

Before Joe even got to the tree, I felt myself getting pulled down the slope at amazing speed. I pressed my crampon heels into the soft snow, trying to stop this rapid, sliding descent, but to no avail. Not realizing at this time that I had tied into the anchor in a spot that would not protect me following the beginning of my belay of Tony, I kept expecting the anchor to grab my harness, pulling me and Tony to a stop. As I slide within a few feet of the cliff’s edge, I dug my right elbow into the slope in an alpine-style arrest in hopes of arresting my slide while continuing to brake the rope with my right hand for Tony, expecting the anchor to stop me, and then Tony via me, at any moment.

Next thing I saw was what looked like the icy cliff flying upward to my left, realizing that I was falling over the cliff. Still expecting the anchor to stop me at any moment, I continued to brake Tony’s rope with a tight fist, expecting an abrupt stop to slam me into the icy wall, bracing for the collusion and the pulling weight of Tony as we both got stopped by the anchor, with Tony hanging from my harness. I wondered why wasn’t the anchor stopping me? I thought this many times during this 2-3 second journey towards the ground. I couldn’t figure out why until about 10 mins later. But about a second later, I came to a very immediate stop. I was dazed, confused, and looking up at the sky. I wondered what happened for about a second, thinking I must had stopped on a snowy ledge of the ice slope, only to realize I had collided with the ground in nearly the same spot I left merely 10-15 minutes before to start my climb. I worried about Tony, looked around, saw him 6′ away looking at me with a confused look. I asked him if he was OK; he replied, thankfully, that he was fine, and asked how I was. I responded, I think, that I was OK but hurt. (Very thankfully, as guilt would ride me for my entire life, Tony was perfectly fine, with my slide at the top slowing his descent until he was about 10′ from the ground, landing softly into fresh snow.)

Several people preparing to start their climb rushed over to check me. Before they could say anything, perhaps they too were dazed, I checked for falling debris from above, saw that I was fairly safe but too close to the cliff to be fully safe in case someone or something fell, yet, I was not ready to move yet and knew I needed to check myself for injuries before proceeding with movement. I wiggled my toes, fingers, moved my hands, my legs, and realized that they all felt fine. My helmet seemed in place, my neck and back did not hurt–was it that I could not feel them or were they OK? I thought about if this was what friend Kirk felt upon breaking his back following a mountain bike injury just five months earlier. As people checked me out and asked how I was, I knew I must had broke some ribs or hurt something on my left side, for it was in pain and difficult to breathe. The other climbers felt my neck, back, and rest of body for injuries. Remarkably, all seemed OK but everyone was unsure if I should move, including myself, but I did not feel safe where I was and wanted badly to walk around and see how I felt. I asked to be unconnected from this rope that just pulled me off the cliff, just to be sure it was not going to pull me along anywhere else. I asked for help getting up, and after several minutes of questions as to my status, everyone was scared but agreed to help me up. Thankfully, several of the climbers there were trained as Wilderness First Responders, like a back-country EMT, so they knew what to ask and what to look out for. I stood up with help from these fine folks pulling me up, seeing that my back and neck were kept relatively safe.

I moved down the slope about 25′ from the cliff bottom, where several fine folks (Mike, Ryan, Valerie, Jen, and others) checked me more thoroughly for signs of back and neck injuries, trauma, internal bleeding, shock, head injuries, etc. We exposed my chest, ribs, back and neck, while they prodded me and asked how it felt. Everything except my ribs seemed fine, and they hurt so bad it made it very painful to stand or walk, which I did to get to this spot. Still wanting to be sure, they had me lay down, made a seat in the snow for me, put some jackets and things down to keep my backside from getting too cold against the snow, bundled me up in hats, jackets and fleece neck gaiters to keep me warm from the briskly falling snow. While I lay there, they had four people walk quickly back to the trailhead, a one hour walk in deep snow and steep slopes, to call 911 as well as bring back a sled to carry me out in, as everyone was expecting to have to carry me out of there or have a helicopter rescue.

As I laid there, the folks listed above along with members of my own team, Tony, LiHan and Joe, brought me drink, food and more insulation to keep me warm. Here is a picture I took of my party as we hiked in:"The Crew"

The crew also tested my mental state with several challenging questions, including three unrelated words to remember, which I still do: equator, raspberry and bee-hive (I worked hard to remember these words amongst all of the action taking place). After about 20-30 minutes, I was getting cold laying in the snow, and felt it best to try to walk out to not only warm myself, but also speed the rescue effort back to civilization. The crew wanted to be sure I was OK to do this, after all, about 5 minutes after the fall, I did go into a semi-unconscious state for about 1 minute, and this was a 40-50′ fall to ground, a very serious collusion (traveling about 40 mph to immediate stop). However, it seemed I either had remarkable cat-like reflexes, bounced off an edge of the slope, the rope pulled me around, or I had several little angels fly in and turn me around, pointing my backside into a soft spot in the snow, for two people saw me my fall and said I went off the cliff face down, which would likely lead to much more serious injuries. I like to think it was the later of these possible explanations, for it took less than a second for me to hit the ground once I left the cliff-edge, seemingly not enough time to turn myself around midair.

So, I got up, tried walking, and it hurt like … as bad as could be imagined. On a scale of 10, with 10 being screaming pain, it was about an 8-9, and nearly a 10 at times. Plus, I could barely breathe, with even the shallowest of breathes being immensely painful. Nonetheless, I decided to walk out and everyone else agreed after much consternation and concern for my safety. So the crew donned me with snow shoes, bundled me up, provided water and other drink and fed me, and armed me with poles to aid my balance. Although my balance seemed perfectly fine, the challenging conditions could easily put me into a slide, or I could loose my balance and fall, causing great pain or more injury. The crew even had someone breaking new trail on the downhill side of the kicked in trail just in case I passed out and fell down hill, causing more challenges for me and my aiders. We walked out of the canyon, crossing the creek, thru the large boulder field with post-holes from our walk in, across frozen Eagle Lake, up and down hills, along slopes, thru deep snow, alongside steep canyons, ducking tree branches, and my crew stayed with me, in front of me, behind me and beside me, checking me along the entire route, asking me how I felt: “fine but it hurts like..(insert bad word)”. Even checking my pulse every 10 minutes and recording it. I did slide once down a slope, falling, and the landing with the ground and getting back up were immensely painful, but overall, my spirits were very good considering the care and help of so many wonderful people. After all, they carried my 60 pounds of climbing gear out on their backs and watched over me like mother’s of a toddler, ensuring my care and safety every step of the way out. About two hours later, we met with four EMTs coming in for me, who checked me out, and we decided I would keep walking out. About 10 minutes later, we met about 12 search and rescue professionals coming in to carry out an immobile, back-injured climber, expecting the worse, not realizing my condition was much better than expected. We walked another 15 minutes to arrive at the trailhead with quite the scene of flashing red lights. With falling snow and very low visibility, thankfully for the expense and unnecessary need of it, a helicopter rescue was not conducted. But the over dozen rescuers, two snowmobiles, and an ambulance waiting at the trailhead was enough. The ambulance crew checked me out, said they would like to take me to the hospital, but my grandpa’s stubborn (and frugal) genes, probably it was also his physically tough genes that also helped me take the hit of the fall, made me ask how much. Upon hearing about $600, and that my friends were capable of driving me to the hospital, and my condition was stable and seemed fine by the paramedics, I decided to ride in with my friends driving me in my car instead of coming in with sirens and horns.

When I arrived at the hospital, I was already famous as they were ready for me, in which a couple of x-rays and a quick yet thorough exam by Doc Curtis revealed broken ribs on left side, a very bruised right arm (maybe from rope or slope slide), and a cut on my face under my right eye (unknown cause of that one). They quickly assessed that I was a type A personality and sent me home with a prescription for pain killer (which they bet I wouldn’t take–for the nurses and doctor, I did take a few the first two days to help me sleep at night). Since then, my back and neck have been very sore I gather from the whiplash of the ground collusion, my ribs hurt bad but are getting better, and I have not run, hiked, biked or swam yet like I figured I would do at least once by my sixth day after the fall. Turns out I am not as tough as I once was, or the ribs hurt more than expected, or I’ve had very little time due to work responsibilities–a bit of a mix of those.

So, there is not much in this post about energy (other than the physics of gravity) or data centers (be safe), and for that I apologize, but there is a very keen lesson here: take your time, especially when it comes to the safety of yourself and others. This goes for daily activities like driving. And anytime you are unsure, or it is very important to have it right, double check, triple check, and/or have another person check. We all don’t hang from large icicles for fun, but we all come into many experiences where this lesson can be applied daily. So be sure to keep yourself safe so you don’t have to own up to your mistake on the Internet like I have here. Be safe, take care, and enjoy life! I’m very thankful following this experience to have little angels looking out after me. Thank you everyone who helped take care of me following this fall on Feb 6, 2010. Thank you, and treat everyone kindly–you might need those karma angels some day.

Batteries

January 29th, 2010

I own a home in the Lake Tahoe region (Nevada side), and it can get a fair amount of snow. Not as much as I’d like most of the time–yes, I like the beauty of the fluffy white water–but around 40′ per year (yes, feet). It often comes in fairly big drops at a time with usually good weather in between. And after seven years of living there (at least part time living there), I finally went out and purchased a snow blower. Before then, it was pure man-power–two snow shovels of different styles depending upon the type and depth of the snow. Yes, I always enjoyed the work out in the fresh air. I have a very large driveway, and used to have a Subaru and other all-wheel or four-wheel drive cars before then, in which I would wait for the garage door to open, the street to be clear of cars, and hit ramming speed so that my car would essentailly fly off the snow on my driveway onto the street. I would repeat the same for getting back into the garage: wait for the door to open, ram the driveway snow and slide into the garage. A couple of near misses of almost sliding into the house were a bit close. Well, after several shovelings in a row with limited time to shovel due to my busy schedule, I thought again about owning a snow blower as a time saver, but I never wanted a 250 pound metal contraption that burns fuel and makes noise, taking up a lot of space all year in my garage for a few uses each year. It seems to make little sense vs my exercise regime. But time was not on my side. Now you’re probably wondering what this blog post has to do with data center or energy…I’m getting to it.

I own a cordless electric lawn mower and weed wacker, each which I love for their silence, no fumes and function-ability. I can mow or trim at 6 AM on a Sunday without disturbing neighbors with noise, I have no tune ups, spark plugs, pull starters, fumes to breathe, oil and gas cans to fill and spill, and less than $3 total per year in electricity. (Yes, I measured it over a full year.) So, I looked into electric snow blowers. Well, there are no cordless ones, only cordless, so I purchased a slightly used Toro electric snow blower and have been amazed with it’s snow throwing ability. It can throw snow, depending upon the depth (the deeper the better) about 10-20′, cuts thru 12″ deep snow, or deeper with a second pass, and clears my larger driveway quicker than my neighbors can do the same with their gasoline powered ones. One problem: cord. Yes, I have a plenty long extension cord and an easy plug I installed for it, but I have to plan out the “route” and keep the cord clear, which is every pass for the first few passes, than about once every ten passes once I get sections cleared. But, a few days ago, feeling lazy and deciding to see what would happen if I ran over the cord instead of clearing it. It was worse than I imagined. Within about one second, the cord was wrapped at least 20 times around the blade, very tightly. After about 5 mins of figuring out how to solve this problem, the unwrapping process was rather easy and quick, but it made me wanting a battery powered snow thrower so as not to mess with a cord at all. Today, battery technologies would make this $250 snow thrower over $1000, many times it’s svelte 35 pound weight, and likely not quite as powerful. It is battery technologies that are one of the greatest keys to solving many challenges, weather to store energy from solar plants, for our many electronic tools and toys, to propelling our transportation. Improved battery technologies at lower cost, weight, and better performance will be key to implementing many energy efficiency, fume reducing, and performance enhancing solutions. Let’s push for much better energy storage technologies; one of the holly grails for many things.

SVLG Data Center Energy Efficiency Summit, video summary

November 20th, 2009

In a recent blog I provided a brief summary of the 2009 Data Center Energy Efficiency Summit held on October 15th at NetApp in Sunnyvale. Here is a fun, short video on YouTube of the event’s highlights. ENJOY!

SVLG Data Center Summit a GREAT Success

October 16th, 2009

Yesterday, October 15th, after a culmination of a year of work from over 60 people, the SVLG Data Center Energy Efficiency Summit went off smoothly. We had 44 presenters, 24 case case studies presented and about 450 people at the summit. The event was hosted by NetApp in Sunnyvale. Representatives from numerous Silicon Valley elites, start ups, VCs, organizations, and solution companies were present. All case studies were presented from data center end-users, showing what they are doing to reduce energy use in their data centers. We had brief sessions about cloud, carbon reductions, notable sessions called the Chill Off 2, in which various cooling technologies were tested with real load in a real data center, also testing the systems at various temperature ranges. Andrew Fanara with EPA gave a quick update of EnergyStar for servers, storage and networking gear. Paul Scheihing with DOE provided an update of the energy efficiency and data center programs. I had a candid interview with California Energy Commission Commissioner and friend Jeff Byron about California’s energy policy, net-zero energy buildings requirement, renewable portfolio standards, energy efficiency standards for TVs and other consumable devices, etc. It was fun!

The day went off without a hitch, thanks to Ralph Renne’s leadership with host NetApp, which provided a wonderful venue and support, with a team of probably 20-30 people directly supporting the event all day, along with a nice keynote from their CEO, Tom Georgens.

Numerous cooling case studies were presented, the Stack Framework which is a method of measuring complete data center load and efficiency, we had a CIO roundtable during lunch, Mark Bramfitt with PG&E talked about advancing PG&E’s compliment of data center energy efficiency incentives as well as his planned departure from PG&E, which caught many in the audience by surprise and left not only tears in Mark’s eyes, but also many in the audience with kind comments from Deborah Grove and others during the Q&A session about his excellent work over many years advancing these programs.

We had a great case study from Intel and NetApp about using on-board hardware temperature sensors to control HVAC equipment, which had some very compelling results within their data centers. Also Cytak presented about turning off computers automatically while not in use using Power Assure’s product.

Overall, a wonderful event. It was great to see so many industry friends and to make new friends. As the co-chair of the program and summit, it was great to see so many people interacting with each other, beginning collaborations stimulated from the excellent case studies presented, which is what the program is all about: Innovation through collaboration. Together we all benefit when we share with each other, and consequently, we as an industry then improves. It was wonderful to see every presenter do a fantastic job showing off their wonderful case studies. No vendors showing off their product, instead, everyone sharing information.

The cocktail reception at the end of the day drew about 200 people that wanted to stay and chat, make friends, and just have fun. So many thanks go out to my committee, which brought the case studies and presentations to us, which includes but not limited to: Bill Tschudi, Bob Hines, Bruce Myatt, Dale Sartor, David Mastrandrea, Deborah Grove, James Bickford, Kelly Aaron, Mukesh Khattar, Patricia Nealon, Ralph Renne, Rosemary Scher, Tersa Tung, and Zen Kishimoto; to Ray Pfeifer, my program co-chair, who brought this program to us last year and so many of the case studies again this year, and his leadership to keep this program about the end-user; to LBNL, CEC, CIEE and PG&E for helping to fund case studies and support the program; to the many sponsors of the summit. And certainly to SVLG for their staff to help make this summit a reality, and most certainly also their lead person, Bob Hines, for his drive and energy. Overall, an excellent day, full of wonderful people, making new and great little discoveries with each other to advance the energy efficiency and financial success of our businesses, and helping to lead the data center industry to greater success.

See me about joining this wonderful program. We are always looking for more case studies and about hosting next year’s summit.

The Data Center Energy Efficiency Summit is Coming Oct 15th

September 14th, 2009

That’s right folks, another summit, but oh no, not just any other summit, this is the 2009 SVLG Data Center Energy Efficiency Demonstration Program Summit, or DCEES (Data Center Energy Efficiency Summit). Originally the brain child of Ray Pfiefer, LBNL, and the CEC, the idea is simple: share energy efficiency improvements by end-users from end-users for end-users. Really simple.

As data center owners, operators and customers, we are keenly concerned about downtime of our data centers, so we tend to shy away from making upgrades unless absolutely necessary, even if it means saving money, and in some cases lots of money. And we also tend to de-value the savings estimates from our vendors as having a reduced level of credibility like clothes detergent commercials saying clothes come out cleanest with their product.

So we pull together technology partners and data center end-users to try out a new technology or process and share the results, good or bad, energy and cost savings. And then the end-user writes a brief case study showcasing the results, the results are peer reviewed or audited by a utility for a rebate, and at the summit, the end-user themselves share their experiences with this new process or product and the actual results. Again, it’s simple. And the concept is too. By sharing what we are doing, we collaborate with each other. And thru collaboration comes innovation. And thru innovation we all gain by reducing our energy use and costs. Meanwhile, the end-user that shared that latest trick is already on to the next one while the rest of the industry catches up, together we all improve.

It’s a fantastic way to reduce our costs, grow our economy, reduce our environmental footprints and implement real solutions that work. And knowing what the challenges and benefits of implementation are from our peers, we can proceed with little risk.

We all gain, we all get educated, and we all get better together. Now isn’t that a program we can all stand behind? At this year’s summit we’ll be showcasing dozens of great case studies from various end users and small and large technology companies, technologies we’ve been hearing about and thinking about. Show up at our Summit on October 15th, at our host’s facility, NetApp, in Sunnyvale, CA. It’s an all day event, full of information, presentations by data center end-users, and meet many in the industry to share ideas, collaborate, and work on that next great idea together. Register and see the full agenda at: http://dcee.svlg.org/

See you there!
