Going Environmental- Energy for Kettle Falls

Today, Thursday October 20, 2011, my environmental science class toured the Avista's Kettle Falls Generating Station for our lab today-- seeing how our community gets electricity. I can see the condensation from both the stack and the cooling towers from my house, and have always just considered it to be some way of making power. I never stopped to think about how it works. I gained a new respect for the people that provide the power for my community and for their environmental concern and standards. Touring this amazing engineering feat was definitely a privilege!

The plant burns wood waste to produce steam, which runs a turbine and generator that can produce a maximum output of 53 megawatts of electricity. The plant also operates a natural gas-fired combined-cycle combustion turbine that produces 8 MW, bringing the electricity output of the entire plant (including biomass and natural gas-fired operations) to 61 MW; enough electricity to power nearly 46,000 homes.
The plant was the first electric generating station of its kind constructed within the United States for the sole purpose of producing electricity from wood waste. 

How the Plant and Biomass Works
  • Wood waste – called “hog fuel” – is fed into a seven-story furnace/boiler and burned, creating heat. The walls of the furnace/boiler consist of pipes filled with water that are heated by the burning hog fuel. The optimal burning temperature is 2,000 degrees, resulting in a steam temperature of 950 degrees. The heated water generates stream and pressure that drives a turbine, which turns a generator, creating electricity.
  • The term “biomass energy” refers to the organic matter in trees, agricultural crops and other living plant material burned to create energy. Avista’s focus has centered on wood waste of various types.
  • The plant burns 70 tons (140,000 pounds) of wood waster per hour during full operations. That amount of fuel would fill two fully loaded semi trucks.
    The plant removes 99.9 percent of particulates from flue gas prior to leaving the stack. (.052 pounds of particulate is released per ton of fuel burned.)
    (Cami inserts: That's about 3 lbs an hour- could fit in your cupped hands!)

Formula For Success: Solve for X

Success = Right Attitude + Hard Work + Best Effort + X
Solve for X

X stands for the key component to success. While the other three of an integral part of the formula to success, you won’t truly get ahead without X.

Let me compare the stories of the two great men that I mentioned in my previous post, Dr. Paul Farmer and Dr. William Foege. Both men have individually made a mark on the world and their names will go down in the history books of medical advancement. Both are alive and actively seeking to do whatever else they can do make a difference for the present and coming generations.

Dr. Paul Farmer is a brilliant Harvard anthropologist, public health expert, and infectious disease specialist. His success story is inspiring, fascinatingly described in “Mountains Beyond Mountains”. Multiple Drug-Resistance Tuberculosis; Famer is an amazing man who is making a difference in how thousands upon thousands of patients are treated and stopping resistant strains of TB. He is an intelligent human being working in the height of modern medicine and seeking changes in the world of health.

Dr. William Foege has changed the world. He has left a mark that removes marks - he eradicated small pox, a disfiguring and life threatening disease, from the face of the globe in the 1970s. As did Farmer, Foege received his masters in public health from Harvard University, after completing medicine at the University of Washington (a graduate from Colville High School, FYI locals!!!). His passion for making a difference sprang from being a missionary to Africa. Even today Foege is actively pursuing research and working with big names in America and the world to positively affect many helpless people around the world.

These are what we all consider success stories. Both of them followed principles that I outlined in my previous posting. Anyone can apply them and find success. What is the difference between these men? What can guarantee you success? 

X. Some of you have already guessed it. Paul Farmer does not have X but William Foege does. Two brilliant minds trained in the same institution; one succeeded on his own, while the other succeeded to a far greater scale, and not alone. Farmer does not claim to know about, or ignores the factor X that Foege relies and trusts in. 

X is God. 

God is the Omnipotent force that granted Dr. Foege the wisdom to eradicate a disease, changing the world. Foege claims Christ. Farmer has succeeded by man’s standards and has done a great deal to benefit mankind, but his success is not half of what it could be if he but had Christ’s infinite wisdom behind him.

When you ask God to give you the right attitude, help you work hard, and you do your best for His honor and glory alone, then you will succeed.

How to Excel and Be a Successful Student

What is successful learning? How do I become a super-star student? How do I excel?

These are questions I’ve pondered a various points in my higher education pursuit. In the last nearly two years I’ve come up with what I believe are the answers to these provoking questions that good-grade-crazy students like myself ponder. However, I can’t say that the answers I have experienced or deduced are the keys to becoming a 4.0 student, but they are the keys to doing the best possible job you can.

Learning is a lifelong process; the lessons I learn in general biology pave the way to greater and higher-level things, such as understanding respiratory physiology or understanding how to explain the defenses of gram-negative bacteria against antibiotics as a test essay question. College is all about building blocks to advanced knowledge. It doesn’t just happen in four years, but likely between seventy-five and eighty years. I can’t expect to learn critical thinking overnight; instead it comes from the process of mind-stimulating classes and real-life applications of class principles.

Success is subjective. To a student who struggles in mathematics, scoring a 90% on an exam is something to buy a burrito at Taco Bell over, while to a perfectionist or idealist, life has just unfriended you. Rather than calling success a 4.0 cumulative grade point average, call it studying to your utmost ability with the best job you can do in mind. For example, I’m not naturally gifted in being able to retain math for longer than a few weeks at most. Since I excel in the sciences I have set myself up for feeling crushed when I am the one that scores 90% on my first math test of the year rather than 99% in Anatomy and Physiology. Just because I can’t pull a high grade in math doesn’t mean I’m a failure as a student. I just have to pick myself up again, maybe re-adjust my definition of success, and go for my goal of doing my best.

Success is about attitude. You can choose your battles when it comes to school. Rather than a pity party with your feelings, why not invest that time into studying for next time? When my emotions begin building over a test score I feel is inferior to my ideals, I have to remember that my success isn’t about the end of the semester class grade, but rather about making the subject my own. I can succeed when I set my attitude in line realizing that I am a failure up until I do my best. Once I try my best I need to have peace knowing that I can’t do more than that. Often times putting an honest effort into a subject is just the ticket you need to do well with your classes, not only emotionally but also scholastically.

Excelling as a student is a great goal, but make school real for you. The world has lots of smart people. India alone has more brilliantly gifted students than America has high school students! No matter how good you are or want to be, there’s always someone smarter. That’s not to put your goals down at all or to sell yourself short of your potential. You should shoot for the moon, but if you don’t get into NASA don’t feel badly. Maybe that kind of success isn't for you. Don’t focus on the college transcript; focus on setting your goals straight. Forget the GPA! I’m telling you! Dump it! Make the information your own. Learn that physics like your life depends on it (guess what? It does!), seek to make understanding the concepts of ecology applicable to how you dispose of your garbage, and apply the principles from communications class to your daily conversations with your family. In short, by focusing on real-life application of learning you will grow in your thinking, reasoning, studying, and yes, even testing abilities! Just as some types of bacteria scavenge around picking up stray genes and incorporating them into their own DNA, you can take the class materials presented you and integrate it right into your every day life!

Excelling as a student means excelling as an individual. Be the best person you can be. Just because there are all those smarter people that doesn’t mean you can’t be smart too. If you set your mind to it, you can do anything. Men like Dr. Paul Farmer and Dr. William Foege have dreamed big and changed the world. If learning doesn’t coming easily, step back to analyze your attitude about success and grades. If you can make the material your own the grades will fall into place. A friend recently told me “We to remember that life isn't always going to give us what we want. We can work hard at something, but in the end, we get what we get”. That means that even if the grades still aren’t great, it’s working hard that counts. Cultivating characteristics that will improve your day to day life and future will be of more value than all the accounting and inorganic chemistry you will ever study!

Success is trying your hardest to do your best.

Let the rest of the school stress be still. It’s not going to get you a better grade. Don’t be afraid of some elbow grease or tear stains on your textbook. Dig in hard, be the person you feel you can be, and don’t give up. Make learning your life goal, and sharing wisdom with others a byproduct of your attempts do make facts experiences.
