January 2020 Meeting of the Technical Society of Knoxville

The Technical Society of Knoxville will meet on January 13, 2020 at the Crowne Plaza Hotel, 401 W Summit Hill Drive.

Anyone interested in the topic is welcome. 

Dr. Peter Thornton, Oak Ridge National laboratory, Climate Change Science Institute and the Environmental Sciences Division, will be the speaker. His speech title will be “What observations and models tell us about likely future trajectories for Earth’s climate system” 

Many people profess unbelief (or indifference) in climate change- this meeting will provide an opportunity to learn the facts necessary to help people who profess unbelief have a clear understanding of where the climate models originate and how reliable they are. This really is the crucial critical challenge for this generation.

Dr.  Thornton studies the interactions of land ecosystems with all other components of the Earth’s climate system, including biogeochemical and physical  land-atmosphere feedbacks, and interactions with human systems.     Dr. Thornton  has been a member of the scientific staff at ORNL since 2008 and he  also serves as a mentor to several technology projects within the Oak Ridge Public Schools, and serves as a board member for the Oak Ridge Public Schools Education Foundation.

November 2019 Meeting of the Technical Society of Knoxville

November 4: John Halliwell will  speak about electric vehicles with focus on the charging infrastructure.  “Where Are We On The Road To An Electric Transportation Future”
John Halliwell is team member in the Electric Transportation Group of EPRI where his focus is smart charging and infrastructure development for plug-in electric vehicles. He joined EPRI in 2007 and has been active in the electric transportation space since 2008. John is the current chair of the SAE J1772 Electric Vehicle Conductive Charge Coupler Task Force and the SAE AE-7D Aircraft Energy Storage and Charging Committee. He has broad experience in design and application of electronic circuits and electronic systems.

Mr. Halliwell received Bachelor of Science and Master of Science Degrees in electrical engineering from the University of Tennessee, Knoxville.

I, Bob Scott, Technical Society secretary, have a 2014 Ford Fusion Energi with a 5 kilowatt hour rechargeable battery. It will go about 20 miles on a charge with the power from KUB costing about 50 cents. The car is a hybrid and it gets almost 50 miles per gallon of gasoline after the rechargeable battery is depleted. My charger is plugged into a 110 volt circuit and it takes about 5 hours to charge the battery. I could get a 220 volt charger and cut the charging time in half but Ford charges about $800 for a 220 volt charger.

You may wonder why you don’t see cars plugged into charging stations- like at Cracker Barrel. In Tennessee I might pay 6 cents per minute for the time I am hooked to the charging station and it might take two hours – or $7.20- for a 5 kilowatt hour charge that would get me about 20 miles- which is less than I get with a half a gallon of gasoline. In other states they charge for the power and not the hookup time. Improved- or radically different- electric vehicle charging regulations, infrastructure and technology can make a big difference in moving our society to mostly electric vehicles.

And maybe we can do something about it. Come to our meeting and find out.

December 9: Jack Dongarra, Prof., Min H. Kao Department of Electrical Engineering, UT: The fastest computers.

October 2019 Meeting of the Technical Society of Knoxville

The next Technical Society meeting will be on the FIRST Monday in October !!

People generate gaseous, liquid and solid wastes. Gaseous wastes have typically been dispersed into the atmosphere and the current practice of dumping unwanted carbon dioxide into the atmosphere is a big problem, but otherwise air pollution is improving. Liquid wastes were formerly dumped unceremoniously into the nearest river but rivers are much improved. Solid wastes from prehistoric times have been deposited in middens and much of what we know about past civilizations comes from a study of the remains of their solid waste. How much solid waste do we people living now generate and where does it go. What will future archaeologists find in our middens and where will they be and how voluminous will they be? 

As an example of solid waste problems Rutherford County, Tennessee, is finding their ” Mount Trashmore” is getting too big and they have consulted with Tom Leonard, General Manager Sevier Solid Waste on how a composting operation works for East Tennessee tourism communities.

Knox County and Knoxville are not immune to solid waste disposal problems and the Technical Society will have an opportunity to learn something about the solutions. Tom Leonard, General Manager, Sevier County Solid Waste, Inc will speak about solid waste recycling at the Technical Society of Knoxville meeting on October 7, 2019.

September 2019 Meeting of the Technical Society of Knoxville

On September 9, 2019 at 11:55 at the Crowne Plaza in downtown Knoxville. Dr. Edgar Lara-Curzio, Distinguished Scientist and leader of the Mechanical Properties and Mechanics group at the Oak Ridge National Laboratory, will be the Technical Society speaker. His presentation title will be “Alternative uses of coal in carbon fiber production”.

Carbon fibers are very popular in aerospace, civil engineering, military, and motorsports, along with other competition sports. Tennis rackets, golf clubs, softball bats, hockey sticks, and archery arrows and bows are all products commonly manufactured with carbon fiber reinforced composites. Lighter weight equipment without compromising strength is a distinct advantage in sports. Carbon fibers have several advantages over other fibers including high stiffness, high tensile strength, low weight, high chemical resistance, high temperature tolerance and low thermal expansion, however, they are relatively expensive when compared with similar fibers, such as glass fibers or plastic fibers, and making them from inexpensive raw materials would be very beneficial (and the coal miners would be appreciative if coal could be used).

Dr. Lara-Curzio leads and manages the scientific and technical operations of a group of 20+ researchers focused on the development and characterization of functional and structural materials for applications in energy and national security.

And looking at a list of his research publications it is obvious that he has been involved with many unique manufacturing evaluations.

He attended CUDEC Multicultural University and Universidad Autónoma Metropolitana in Mexico for his degree in Engineering physics and he has a PhD degree in Materials Engineering from Rensselaer Polytechnic Institute.

August 2019 Meeting of the Technical Society of Knoxville

On August 12, 2019 Dr. Lou Qualls will speak to the Technical Society about the new molten salt reactor. Our nation has a need for baseload electric power and many of the existing nuclear power plants will soon be up for license renewal. It is unlikely that any conventional nuclear power plants will be built in the future. What will be the future of nuclear power?

The Department of Energy’s Office of Nuclear Energy (DOE-NE) has selected Lou Qualls as the national technical director for molten salt reactors . In his new role, Qualls—a nuclear engineer who joined DOE’s Oak Ridge National Laboratory in 1988—will serve as a liaison among the nuclear industry, the national laboratory system and Department of Energy in defining the future of molten salt reactor technology in the United States.

Dr.. Qualls has said “If we are going to replace the current fleet of reactors with new technology, we need to begin focused efforts immediately. The nuclear industry needs to become better at evolving and incorporating new technology and molten salt reactors provide that opportunity.”

future Technical Society programs:

September 9: Dr. Edgar Lara-Curzio, ORNL: Alternative uses of coal in carbon fiber production. 
October 7: Tom Leonard, General Manager, Sevier County Solid Waste, Inc.: Solid waste recycling.

July 2019 Meeting of the Technical Society of Knoxville

On July 8, 2019 Shafik Iskander, P.E. will discuss” Fracture mechanics analysis of irradiated reactor pressure vessels.” (PDH)

One of the problems in dealing with nuclear fission in a nuclear reactor is the radiation. Radiation is absorbed in the steel reactor vessel and it is not benign. The steel changes! And the cost is substantial if the steel weakens and the reactor has to shut down.

Dr. Iskander has spent a lifetime studying materials and nuclear energy and this is an opportunity to learn about a critical question that is important to everyone from an expert.

His resume is below:

Graduated from Cairo University ,Egypt, with a B.Mech.Eng (1956) and M.Sc. in Material Science (1967). He emigrated to the USA in 1968 and while pursuing a doctoral program in Engineering Mechanics at University of Tennessee, Knoxville, was a full-time instuctor.

He received his Ph.D. in 1972, joined Computer Science Division at ORNL, and continued as an Adjunct Professor at UT. He was Group Leader of the Engineering Mechanics Group, and developed computer codes still in use. In 1982 he began a 4-year assignment as Resident Engineer for the U.S. Nuclear Regulatory Commission (USNRC) in Stuttgart, Germany. He acted as liaison between USNRC and the nuclear community and traveled to many European countries. On his return from Germany, he joined the Metals & Ceramics Division at ORNL, and traveled to many countries including Russia and Japan. At the request of the International Atomic Energy Agency (IAEA), Iskander traveled twice to Argentina to lecture on reactor pressure vessels. Iskander is a Registered Professional Engineer in the State of Tennessee and is fluent in German, French and Arabic. After leaving ORNL he founded a consulting firm. 

He has been there!
