118 Days

Thursday, May 31st, 2007

For those of us who worked with Emily, this Intern’s journal  is a tear jerker, especially as we head into a summer without a single Emily on project:

118 days

I arrived at the co-op in January of 2007 having never made biodiesel or even driven a diesel vehicle.  I’m convinced that the reason I got the internship was because of Piedmont’s policy of always having an ‘Emily’ on the project, but I wasn’t about to complain.  After spending the previous three months applying to chemical engineering PhD programs, I was excited to do anything that did not involve writing, editing, or re-writing essays about my academic research interests (photocatalytic energy generation … in case you’re interested).

Actually getting my hands dirty and making biodiesel sounded like a great way to spend my time before I returned to grad school and years of making precise measurements of very small things in a sterile laboratory.

It took me a couple weeks to familiarize myself with the day-to-day operation of the co-op and memorize the Piedmont Biofuels “elevator speech” but after that, the ball never stopped rolling.  I quickly went from asking questions about biodiesel to answering them as if I were an expert.  Every week was filled with clean tech demos (which I enjoyed more than I ever admitted), class at CCCC, working at Industrial, Sunday tours, tours for those “extra special” groups of people that we had to squeeze in at the last minute, and of course making fuel.  I could barely find time to visit the grad schools that I did get into, and as a result missed enough Sunday tours that Greg will probably hold a grudge against me forever.
All in all, I spent 118 days at Piedmont Biofuels.  During that time we got a lot of stuff done.  We added insulation to the windows of the Grease Warming Zone (GWZ).  We revamped the co-op fuel making process (yeah heat) and started making two batches a week.  We talked to a lot of people in rural North Carolina about biodiesel (and I revived my southern accent).  I spent a lot of time knee-deep in stinky mud to expand our artificial wetlands system, and even more running tests for Rachel at the Industrial  lab.
My time at Piedmont taught me how much I didn’t know.  Funny that I can have a degree in chemical engineering without ever having installed a heat exchanger, plumbed pipes together, or used a hose clamp.  Funny that I spent a year getting a master’s degree that focused on renewable energy technologies, yet my textbooks didn’t even contain the word “biodiesel.”  Funny that I have taken more chemistry classes than I can count, yet I still needed someone to explain the kinetics of a transesterification reaction to me a couple of times before it hit home.  All of my previous work experience has been for large multinational engineering companies.  There I was taught to think that it was impossible for people without engineering degrees to build a chemical plant, regardless of how intelligent and passionate they are.
During my 118 days, I had to relearn a lot of things.  Piedmont works very differently from the giant corporations I had interned with in the past.  Things move fast.  An idea born late on a Monday night can be fully implemented by Tuesday afternoon, no sweat.  The amazing people who run the place can come up with creative solutions to last minute problems that would never make it through the red tape at a larger company.
Over the course of my internship, I came to admire the controlled chaos and elegant simplicity that manage to keep abundance flowing at the co-op and industrial.  I learned a lot about biodiesel, the meaning of sustainability, and myself. It is ironic that I traveled halfway around the world to get that degree in “sustainability” when the whole time there was a sustainable community springing to life in my back yard.
Like the other Emilys I am not staying on project, but heading out into the wild yonder to try my hand at something new.  I have just moved to Washington DC, where I will spend the summer trying to convince Congress to increase the use of biodiesel in the military (wish me luck…).  After that, I am making the long trek to southern California to return to my academic roots and a lab coat at Caltech.  And after that … I’m not sure where the winds will take me, but I do know that regardless of my final destination, my 118 days at Piedmont Biofuels has been an important part of my journey.

Summer School

Tuesday, May 29th, 2007

For many pre-medical students, summer courses look like a great way to get ahead of the curve and fast-track through your introductory sciences, math or general educational requirements. For some medical students, summer coursework is an opportunity to shore up deficiencies or remediate coursework from the previous year before academic progress is granted. In both the case of the undergraduate and the medical student, there are characteristics of summer coursework that need to kept in mind.

Summer courses at any level go very fast. There simply are not enough weeks during the summer months to allow the same pace as regular-term coursework. Keeping this in mind, prepare to work faster and longer to master the same amount of material as a regular-term course. In the case of repeating a medical course -or remediation of previous course work-you are expected to be able to move through the material faster because this is the second time you will have covered this material. In the case of an undergraduate course, the summer student has to be dedicated and disciplined during a time when many of your friends are enjoying a much needed vacation.

My rules for mastery of coursework apply for summer coursework but let’s call the rules “course mastery on steroids” because you have to devote more time and cover more material at each sitting. There is little time to allow the material to “digest” before you move onto another topic or lecture. To this end, your previewing and reviewing become more focused in addition, the student has to be more adept at moving through the material at a more rapid pace. If mastery of concepts comes slowly, summer school is not a very good idea.

In the case of the remediating medical student, this being the second time through gives you an added advantage in the sense that you already have good insight into what you need to master. Each time the material is presented, you will gain new insight. This doesn’t mean that doing a summer medical school class is going to be wonderful and a “cake walk” but it does mean that you will likely know your remediated material in great depth for your board exams. This is not a bad trade-off for missing your vacation time and staying with the rest of your medical school class.

I never recommend that pre-medical students take pre-med coursework during a summer session. Summer courses move so rapidly that there often is not enough time for good integration and mastery of the concepts in sufficient depth for application on the Medical College Admissions Test (MCAT). Good summer courses are English courses, History courses, physical education coursework and math coursework. By taking these types of courses during the summer, a pre-medical student can get pre-medical course pre-recs out of the way or get degree requirements out of way allowing more time for concentration of major subjects.

Other great summer coursework for pre-medical students are “immersion” type courses such as marine biology (on a ship at sea), summer semester in Europe or South America, or summer research. Being able to devote your attention to one subject in total immersion can greatly enrich your college experience. Many undergraduate institutions offer immersion language coursework over a summer or opportunities to work with world-class researchers during a summer session.

Summer Course Study Strategies
As soon as you receive your course syllabus, reading/lecture schedule, sit down and plot your study schedule. You need to figure out how much time you will have to devote to study in order to cover the material. A good rule of thumb is two hours of study time for every hour of lecture time (same as for regular session). Since summer lecture are often longer (or take place five times a week instead of two or three), you have to block out your study time without exception.

Be sure that you have a strong and organized approach to mastery of your material. Having a buddy in the same class to study and work with becomes invaluable especially when you quiz each other and explain concepts to each other. It is also a good idea to meet with your instructor on a regular basis to be sure of your understanding of your coursework. Since summer courses go so fast, you do now want to “dig into a hole” that you are constantly attempting to pull out of. Chances are not good for pulling up, if you get into trouble on a test.

Because of the heavy concentration and course time commitment, working will be very difficult with summer courses. Unless you are taking a physical education course or a performance course with minimal prep time, working will be very hard. The effort that it will take to keep up with your course materials will generally rule out employment except for either a Saturday or Sunday on the weekend (but likely not both). If you need money, opt not to register for a summer course unless you have a job that permits long hours of down-time regularly. Even then, attempting to work and do a summer course will be very difficult.

If your family (or you) have an elaborate vacation planned, do not expect that you will be able to “miss a couple of days” of your summer course. You should have enough time for a weekend at the beach or to take a short trip but missing a day of summer work is equivalent to missing a week of regular session work. Again, opt not to take a summer course if you NEED your vacation time. Taking the time off is a better use of your summer instead of attempting to take a summer course and doing poorly because you had to go on vacation. If summer school is your plan, it IS your vacation.

Biodiesel Man

Tuesday, May 29th, 2007

Greg came to us from New York. His internship was for the winter semester of 2007. When he finished in the spring, he gave up his amateur status as fuelmaker, and joined us at Industrial. Here is his
journal :

Biodiesel Man

In the little world which I inhabit, biodiesel somehow creeps into every conversation. It’s like I have a friend with a very exciting life that we can live vicariously through. The first time I met him (it’s him to me, no offense) was in Flagstaff, Arizona where I was thinning forest and building trails in an Americorps program. I was impressed by the fuel, but somewhat unimpressed by the bus full of hippies that brought him. He and other alternative energies where on my mind in Moldova, where I stayed for 2 years trying to accomplish something useful, but the timing wasn’t right. Finally, when I returned to the US in November of 2006, I could put some energy into getting to know him.

I came across Piedmont Biofuels searching for internships and jobs at idealist and I was lucky enough to come down for my interview when Girl Mark visited Pittsboro to do a short biodiesel class. The first thing you notice about the folks who really hang out with biodiesel (not the one’s who just say they do) is that they are never quite normal. Girl Mark’s name, in every informal and most formal uses, is still Girl Mark. Matt Rudolf went to Guatemala with the money he got from selling his car and had no institutional backing whatsoever (the undertone of our first conversation was “Peace Corps is for wussies”). I’m always hearing the tail end of stories about what Lyle did “in his youth”. The other thing you notice is that they are motivated, sharp, and have a different and very valuable view of the world. The uninitiated might confuse them with some segment of hippies, but then frankly, most of the uninitiated can’t even keep up with them.

I was out of my element in every way possible. I knew little about biodiesel. I could not weld, nor plumb, nor choose the appropriate pump based on the situation. I haven’t worked in a lab since 11th grade when I did assays to measure protein levels in egg yolks. These were skills that biodiesel likes (not the egg thing exactly, but certainly the others), and I had none. I thought if I could buddy up with biodiesel maybe I could pick up a thing or two. So when Matt said I was in, I prepared to learn.

The coop is a great place to get to know biodiesel and to learn what biodiesel needs from you because nothing is ever (ever!) finished. The wetlands, the oil water separator, the bubble wash and dry, and the heat exchangers in the reactor were just a few things that we interns changed. We accomplished these tasks in the time honored tradition of trial and error, with a healthy dose of error. We soon realized that plumbing is pretty easy, pumps can be understood if you know where to look, and that most of the time you don’t need to know how to weld. Experience in making batches helps to improve your visual, tactile, and sometimes olfactory understanding of biodiesel and it can save you time. It didn’t take long before we were being productive and though clearly still novices, we knew biodiesel better than Joe Public.

And thankfully we got to tell Joe Public that at least once a week. A large part of our job was to go around to community colleges, seminars, sustainability events, and generally wherever Matt said to let people briefly cross paths with biodiesel with the hopes that they want to meet him again soon. This served as a big confidence booster for us interns. At Piedmont we were at the bottom of the biodiesel knowledge totem pole, but we could give a great and convincing speech to most anyone else. It also gave us a chance to understand the reality of people’s perceptions of biodiesel, from the “how much does it cost to convert my car to run biodiesel” person to the ever-present “what about NOx” guy. And even though there are a lot of questions, it usually doesn’t take much convincing for people to see that biodiesel has an important role to play in our energy present and future.

My internship at Piedmont Biofuels was a perfect stepping stone into the industry, just as internships should be. I feel lucky that they offered me to stay on to make fuel at the industrial facility, so even though the housing is not great, the pay is worse, and the grease stains are permanent, the experience was truly one-of-a-kind.

In staying on project, not only do I get to continue to hang out with biodiesel on a daily basis, but I also see the rest of the not-quite-normal Piedmont staff. It’s not every day that you meet the type of people who work at Piedmont, and it’s almost never that you see so many in the same place. It takes a pretty special someone to attract so many good folks - that’s our friend biodiesel.

Eat Local Dinner

Monday, May 28th, 2007

The Abundance Foundation is holding a fund raiser at the plant.  They intend to serve local food to the first seventy five folks who sign up.

Apparently the ex-chef from The Lantern is stepping in.  And Todd from ECO Organics is stepping in.  He was a chef in his past life.  And I believe my children have been deputized as wait staff.  They are well trained from their many years of waiting on me hand and foot.

This dinner is set for Sunday, June 10th, and it is twenty five bucks a head-ten for children.  Proceeds go to the Pittsboro Farmer’s Market.

Our local fuel project is necessarily on the edge of the local food scene.  Tes did a marvelous job of covering Carlo Petrini’s Triangle visit in her blog.  I stayed home with children that night and worked with Zafer on a Ten Year’s After song.  He’s moved to the electric guitar, and his walls of sound fill the farmhouse these days.

Apparently the local Tilapia farm has sold out to golf course developers, and they are moving their aquaculture operation to a farm across the road.  That’s making for a bunch of orphaned fish, which are headed to Eat Local Night.

The idea behind the project is to raise a bunch of cash for the Farmer’s Market.  The Farmer’s Market is not “in trouble,” in fact it is having its best year ever.  But it could use some cash for banners or signs or whatever it takes to get the word out.

What better way to support the local market than to come to the biodiesel plant for a simple sit-down dinner for seventy-five?  Buy your tickets early…

Study Skills - Part III

Sunday, May 27th, 2007

In this short essay, I am going to tell you something that I didn’t do that I should have done. It’s called “Learning by Experience”. When I started graduate school, I vowed to get myself into good physical condition. I had a few extra pounds but nothing that was morbid obesity just about ten extra pounds. I had been a middle distance runner (10K) off and on with my best mile time being 6:25 and my best 10K time being 40 minutes but working in the chemistry lab and getting ready for graduate school had eroded most of my base-line mileage. I saw the pounds creeping on and I decided to “stem the tide” right then and there.

I joined a gym where loads of guys from the U.S. Navy JAG office worked out. Soon I was grunting and sweating with the boys. Those extra ten pounds quickly melted off and I would run 4 to 5 miles daily. My flexibility increased and my brain loved the extra perfusion of oxygen from those daily runs either outside on the bike paths or inside on a treadmill. My workout partners, all JAG guys, introduced me to weight training. Soon I was benching 125lbs and leg pressing 400lbs.

I loved swaggering into the gym in my baggy gym pants and muscle shirt. I would hop on the stationary bicycle for a 6-minute warm up. After a few stretches, I would start my circuit working legs first then arms and finishing up with abs. I wore a red scarf on my head and definitely sweat as much as the guys. When I reached 80lbs on the bench press, I earned a spotter. Nothing gave me more satisfaction then when the guys and I would take turns on the chin-up bar. (No other women came near the bar). My biceps and triceps bulged. I would put 400 lbs on the leg press and just work away with some nice hamstring stretches in between.

After my weight-lifting, I would take a soak in the Jacuzzi and then a dip in the pool. I am not much of a lap swimmer but swimming a few laps would bring my body temperature down and would keep my back stretched out nicely. My entire gym routine took about 2 hours from start to finish. I would get a protein shake in the juice bar and head back to my lab feeling powerful and refreshed.

The best thing about being in such great shape was that the discipline of working out carried over into all aspects of my life. I slept better at night with no stiffness in the morning. I easily ran flights of steps and could carry heavy loads with no problem. My clothes fit great. I had a solid study plan that had gotten me a 4.0 in my graduate studies. While I ran, I thought of new experiments and analyzed my data in my mind. Though my diet was not bad (I am not much of a junk food eater), when I was working out, it was excellent. I ate plenty of fresh vegetables, fruits and little meat.

With all of my energy, I was able to awaken in the morning, run a couple of miles with the Marines from the barracks down the street, and then bike 6 miles to school in the dawn. I would check my experiments and review my lectures for the day. I would then shower (I really sweat when I bike); change into my suit and lab coat, and then do my morning lectures. During lunch, I would hit the gym. After lunch, I would study and prepare more experiments or go to meetings. This was the routine of an assistant professor.

When I decided to attempt medical school, I knew that I needed to take the Medical College Admissions Test (MCAT). I had far more coursework between a double major in biology and chemistry with double minors in physics and math. My graduate work was in Biochemistry and Molecular Biology so those subjects were well covered. I knew that I needed to brush up on my verbal reasoning skills so I bought a review book and worked some problems daily. I also worked on my Physics too since it had been five years since I had taken General Physics. I was solid on the Quantum Mechanics but Classical Mechanics and Optics needed review.

My graduate comprehensive exams were also looming that summer too. We would be examined over the course of two days with eight hours of testing on both days. I studied for my comprehensives and studied for the MCAT at the same time. This turned out to be a great strategy. I simply made a review schedule topic by topic and checked off as I reviewed each concept. As a poor graduate student, I couldn’t afford a prep course so I purchased ($35) a huge review book called Flowers and Silver. It was money well spent.

After completing my comprehensives in June and getting my AMCAS application done, I knew I had one month to prepare for the August MCAT. I had stuck to my study schedule and my workout schedule. The funny thing was that none of my graduate school colleagues, except my best friend, knew that I was even interested in medical school. My best friend in graduate school was a neurosurgery resident who was working on his Ph.D. We had been study partners for the comprehensive exams.

On the morning of the MCAT, I hopped on my bicycle and rode the 6 miles to my testing center. It was great rolling off the hills at top speed and feeling the early morning wind in my face. My legs were strong and I imagined myself “smashing” that exam as I pumped up and down the street. I stopped into my favorite coffee shop for a morning cup of fresh “joe” and a high-five from the shop’s owner (a little Korean lady who always offered me encouragement).

I stood in line, dressed in my bike shorts and muscle shirt with my helmet and gloves. I stretched some but other than that, I was pretty relaxed. I could feel the tension all around me. As I got to the test room, I hoped for a seat next to the window because outside, there was a beautiful pink blossomed tree. I knew that I would be able to look up and out the window for a little mental break if the test was too much. My prayers were answered as I took my seat next to the window.

I moved through the Verbal Reasoning. My strategy was to do the passages that I found least interesting first and the things I loved last. I paced myself reading the questions first and marking the answers as I read through the passages. I paid close attention to punctuation, tone and critiqued in the margins of the test booklet. Soon this portion of the test was behind me. About ten minutes into the test, three young men, arose from their seats and left the test center. Was I missing something? The entire test went fine for me with my being able to figure out the “hook” behind each question. It was more like a game than anything else.

At the end of the test, I rode to my lab, checked my experiments and said a “thank-you” to God for giving me a nice day to ride and a clear head. From then on, I was stayed in great shape and kept working out clear up until the last day of medical school orientation. When classes started, I started studying and eating. My study group would feast on Nacho Cheese Doritos as we quizzed each other. By the end of first year, I had gained 30 pounds. My teaching over the summer and second year packed on another 20. By the end of medical school, I had gained 65+pounds and carried that weight around until my third year of residency.

After three years of standing and huffing up stairs, I vowed to get the weight off. I didn’t have two hours to work out daily but I made time for an hour workout even if I lost sleep. On my call days, I would walk the steps. Soon I had a good aerobic base but I am still working on getting my weight lifting back up to my level before. Even today, I work out at least four to five times weekly doing something. My gym opens at 5:00AM so I can get an hour in on the elliptical trainer if necessary.

In short, in medical school, I let my fitness level drop and endangered my health. I am fortunate to be able to get back to my previous level of fitness though the weight is not coming off as fast as I would like. I know that I won’t lose as much weight until I can get my running base back and I won’t pound my knees until I have lost another 20 pounds. That day is coming though.

In short, get a good fitness plan today, if you don’t already have one. It can be as simple as a 30-minute walk after dinner. Keep yourself in good physical condition and take an hour for yourself because you deserve that time. Physical exercise drops your stress level and makes everything in your life hum. I am having some “zone days” now that my physical condition is getting better and better. Having a good physical conditioning strategy is as important to your studies as your textbooks. Get moving.
