Infrastructure News (Mostly Missouri)


Safety Valves Required on Gas Connections

The U.S. Department of Transportation, which governs gas pipeline safety through its Pipeline and Hazardous Materials Safety Administration, issue rules that require safety valves to be installed on all new or replacement gas service lines for apartments and small businesses. Excess flow valves automatically shut off the flow of gas when a line is ruptured, limiting the amount of gas that can escape, which will prevent or reduce the severity of fires.

Such valves have been required for new and replacement connections for single-family residences since 2009. The rule does not require existing connections to be retrofitted with the valve.

Tennessee Valley Authority Puts Unfinished Nuclear Plant on the Market

The Tennessee Valley Authority (TVA) is offering for sale its Bellefonte Nuclear Plant. TVA began construction of the plant, located near the northeast Alabama town of Hollywood, in the 1970s, but never completed it because regional power demand did not grow as anticipated.

TVA has set a minimum bid of $36.4 million for the plant and 1,600 acres of land along the Tennessee River. This is fraction of the $5 billion the authority has spent on the project. In addition to the unfinished nuclear reactors, the property includes power transmission lines, roads, and several buildings.

TVA cites economic development as a reason for the sale. It hopes industry will be attracted to the developed site and provide employment in the region.

Wind Farm to Start Operation in Missouri

Next Era Energy Resources is anticipating completing construction of a wind farm in rural DeKalb County, MO, in November. The facility will have 97 turbines and be capable of generating 200 MW. Kansas City Power and Light will purchase the energy. Find out more in this article from the St. Joseph News-Press.

Engineering Educators Elect First Black Woman President

The American Society for Engineering Education elected Bevlee Watfort as its president. She is the first black woman to hold the office. Her term will begin in June 2017. Watford is Associate Dean of Academic Affairs at Virginia Tech’s College of Engineering.


Missouri Testing Solar Sidewalk at Rest Stop

The Missouri Department of Transportation (MoDOT) announced it will install sidewalk made of solar panels at its Route 66 Welcome Center. The sidewalk will cover a 12-foot by 20-foot area at the rest stop on Interstate 44 near Conway, MO.

The panels will be supplied by Solar Roadways of Sandpoint, ID. The solar panels and electronics are sandwiched between to ½-inch thick layers of tempered glass. MoDOT will test the materials for durability under various weather conditions. It will also test the suitability of the panel’s built-in LEDs as substitutes for road striping.

MoDOT does not expect to sell power from solar projects. It envisions that solar roadways may generate enough power to supply rest areas. The power generated by this project will be directed to the welcome center building.


Bill to Change Missouri Water Commission Overcomes Veto

The Missouri General Assembly overturned a veto by Governor Jay Nixon of a bill that could change the composition of the Missouri Clean Water Commission. The bill would change the composition of the commission, allowing agriculture and mining interests to have a larger representation. The commission has authority over rulemaking under the state clean water law. You can read more about this here.

Oklahoma Shuts Down Waste Wells in Light of Earthquake Threat

The September 3rd earthquake on a newly discovered fault near Pawnee, Oklahoma, has prompted state and federal officials to halt injection of oil and gas wastewater into 67 wells in the area. There is a growing scientific consensus that wastewater injection has contributed to recent earthquakes in the Oklahoma.

Wastewater produced from oil and gas extraction is disposed of by injecting it deep into the ground. Reducing the amount of wastewater that can be injects also reduces the amount of oil or gas that can be collected. The wastewater cannot readily be disposed of by other means.


The magnitude 5.8 quake was felt in neighboring states (Facebook friends of this contributor reported feeling it in St. Louis and the Missouri Bootheel). The U.S. Geologic Survey reports that it was felt as far away as Nevada and Florida.

All About Missouri This Week

Bill Prefiled to Ban Texting and Driving

Missouri State Senator David Pearce has prefiled a bill that would prohibit the use by all drivers of hand-held mobile phones to send, read or write text messages. Find out more here.

Gubernatorial Candidates Discuss Tranportation Funding (Just a Little)

So far, Missouri’s candidates for governor have provide few details about how the state will pay to maintain roads. Missouri is 7th among the states in the size of its transportation system, but 47th in state funding.

Candidate Catherine Hanaway suggested that the $200 million annually in state fuel tax revenues that is used to fund the Highway Patrol could be committed to transportation. The Highway Patrol would be funded from general revenue, though Hanaway’s plan does not provide specifics about how other general revenue-funded programs would be cut or how general revenue would be increased. You can find more about Hanaway’s proposal here.

The state General Assembly is also looking at the issue. A prefiled bill (HB 1381) would raise the state fuel tax from 17 cents to 19 cents per gallon.

First Woman Engineering Dean at University of Missouri

My alma mater, the University of Missouri College of Engineering, has named its 11th dean, Elizabeth G. Loboa. She is the first woman to hold the position. Loboa has a background in biomedical engineer. Before coming to Mizzou, she held a joint appointment at the University of North Carolina-Chapel Hill and North Carolina State University.

Highway Commissioner Appointed

Gov. Jay Nixon appointed Hannibal-area lawyer John Briscoe to serve on the Missouri Highway and Transportation Commission. The appointment must be confirmed by the Senate.

Springfield Buying Wind Energy


City Utilities of Springfield announced it will be buying energy from a wind farm to be built north of Oklahoma City, OK. The wind farm is being built by Duke Energy Renewables and is designed to produce 200 megawatts.

Book Review: #STEM Books for #DeSTEMber

I’ve reviewed 39 STEM-related books (and counting).  STEM is an acronym for science, technology, engineering, and mathematics.  As you may have seen in the news, there is a push to improve STEM education, interest students in STEM fields, and grow the number of workers in these fields.  The idea is that these will be the skills needed by workers of the future.  If you’re a STEM educator or a student considering a career in STEM fields, you might like to take a look at some of these books.

I’ll confess that I’m not an educator, but I think most of these books will be accessible to high school and college students, and a few to middle school students.  The list is also a reflection of my career and interests in engineering, public health, policy, and history.  Even with these biases, I think it is a good list for someone looking for STEM-related books.

How to Build an Android: The True Story of Philip K. Dick’s Robotic Resurrection by David F. Dufty

I was fascinated by robots as a kid.  I enjoyed reading Isaac Asimov’s robot stories.  I longed for the Omnibot 2000 in the Sears Wishbook.

Robots have come a long way.  In How to Build an Android, David F. Dufty describes the short strange life of a very complex robot made to look and talk like science fiction author Philip K. Dick.  The robot had a very sophisticated and lifelike head and complex artificial intelligence.  As with most complex things, it was the work of many people who had to solve a lot of problems.

If you’re interested in robotics, this is an interesting nontechnical book.  In addition, you’ll get introduced to some freaky sci-fi.  You may even get as (somewhat) legitimate reason to use the word “Dickhead” (capitalized, it refers to a fan of PKD, so don’t go using it on anyone).

 

The Big Roads: The Untold Story of the Engineers, Visionaries, and Trailblazers Who Created the American Superhighways by Earl Swift

The Interstate highway system in the United States is one of the most enormous structures built.  Some of the prospective STEM students who read this may actually be younger than the Intestate system, though in some sense it is never complete because it needs constant repair and maintenance.  The Interstates were completed in the 1990s, but the Federal-Aid Highways go back to 1916.

 

Earl Swift wrote an accessible history of the Interstates in The Big Roads.  If you interested in automobiles or transportation, it’s a good read.


 

Dreams of Iron and Steel by Deborah Cadbury

Deborah Cadbury describes seven wonders of engineering in Dreams of Iron and Steel.  It covers almost a century of history, but many of the events are concentrated in the Victorian Era.  That was a time of great technological innovation.

 

Though the book is history, many of the structures still stand.  Railways, the Brooklyn Bridge, the Suez and Panama Canals, and Hoover Dam stand testament to an age of big engineering.


 

The Physics of Superheroes by James Kakalios

Though the memory of Professor Wragg’s sneer prompts me to not make this confession, part of my interest in science and technology came from comic booksIron Man was cool.  Spider-Man’s web shooters were very cool.  Superhero comics are full of fantasy, admittedly, but the strange, unrealistic science and technology they depict have inspired many to study STEM in reality.

 

Physicist John Kakalios uses examples from comic books to explore real physics in The Physics of Supeheroes.  Sometimes comics get there science right.  Even when they get it wrong, it can be instructive.  If you know what people are talking about when they refer to the “New 52,” you may find this book to be a great introduction to physics.


 

1089 and All That: A Journey into Mathematics by David Acheson

Here is another confession: I’m not especially interested in math.  I endured a lot of math classes to study engineering.  Reading David Acheson’s 1089 and All That did not require such endurance.  For one reason, it is a short book.  For another, Acheson doesn’t expect his readers to be mathematicians; it is enough to follow the outline of the math he discusses.

 

I recommend this book because so many people have a fear of math.  1089 can be followed by many high school students and older folks with math phobias.  Just take a deep breath, relax, and follow along as well as you can.  You’ll see that math can be interesting, useful, and even beautiful in a way.


 

The Brooklyn Bridge: They Said it Couldn’t be Built by Judith St. George

Judith St. George’s The Brooklyn Bridge is a short history of and iconic bridge.  Written for the bridge’s 100th anniversary, it is also the story of the engineers who sacrificed life and health to see it completed: John Roebling and his son Washington.  John Roebling was a German immigrant who built many suspension bridges and owed a wire-making business.  He gave his son and extraordinary education in bridge engineering for the time, and before beginning work on the Brooklyn Bridge he served as an officer in the Union Army during the Civil War.

 

Why should a cutting-edge STEM student read about a bridge that is almost 130 years old?  It’s because we still use and rely on very successful, centuries old technologies.  Improving and rebuilding our infrastructure will be an important part of our economy.  As recently as 2010, New York City and the federal government committed $500 million to repair and repaint the Brooklyn Bridge.


 

The Essential Engineer: Why Science Alone Will Not Solve Our Global Problems by Henry Petroski

STEM lumps together science, technology, engineering, and mathematics.  Is there a difference between science and engineering?  Is it important?

 

Henry Petroski, a professor of civil engineering and history and author of The Essential Engineer, believes there is an important difference.  At heart, science is about increasing knowledge.  Engineering is about invention.  Of course, new knowledge makes new invention possible.  Just as often, though, engineering runs ahead of science.  Sometimes science didn’t advance until someone invented the instruments to conduct new observations and experiments.  The invention of the microscope made possible the science of microbiologySteam engines were built and greatly improved before we had a modern scientific understanding of thermodynamics.  In fact, thermodynamics was to a large extent born out of desire to understand steam engines. In this sense, it is an engineering science (study of manmade things) as much as a natural science (study of natural things) or branch of physics.

 

Petroski’s focus in the book is the importance of engineering to policymaking, where it is often overshadowed by science.  Policy, science, and engineering play off of each other a lot.  Most of my career as an engineer has been related to government, policy, and regulatory compliance.


 

The Ghost Map: The Story of London’s Most Terrifying Epidemic—and How It Changed Science, Cities, and the Modern World by Steven Johnson

The Ghost Map by science writer Steven Johnson is the story of the birth of epidemiology.  Epidemiology is a medical science that uses statistics to help us understand how diseases operate in a population.  Using various statistical and geographic tools, long before we had computers and GIS, physician John Snow demonstrated that cholera, once a recurring plague that wiped out hundreds of thousands of people in some outbreaks, was a waterborne disease.  This understanding, initially met with much skepticism, allowed officials to intervene to prevent the spread of the disease.  For those who say of their math classes, “I’ll never us this,” here is a case where math (and science and policy) were used to make a great difference.


 

Undaunted Courage: Meriwether Lewis, Thomas Jefferson, and the Opening of the American West by Stephen Ambrose

It is not much publicized today that the Lewis and Clark expedition of 1804 to 1806 had a partly scientific mission.  Captains Lewis and Clark were charges with bringing back samples of the flora, fauna, and culture of the western territories.  It was also hoped that they would find a water passage to the Pacific Ocean.  In Undaunted Courage, Stephen Ambrose writes about the scientific mission as well as the policy, diplomacy, and commercial hopes the expedition carried.

 

Of course, what attracts most people to the Lewis and Clark expedition is that it was a great adventure.  There is a place in STEM fields for thoughtful adventurers and explorers. 


 

Buried Alive: The Terrifying History of Our Most Primal Fear by Jan Bondeson

A list like this deserves something strange, creepy, and more fun than you care to admit.  Right now, thousands of very young future STEM workers are catching bugs and snakes, breaking their toys to see what is inside, or staring into space with a weird expression of vacancy and concentration.

 

Jan Bondeson’s Buried Alive is not a morbid book.  It is sometimes humorous, especially in consideration of topic.  From a STEM point of view, Bondeson shows how knowledge accumulates over time.  The fears and activities of our forefathers may seem strange to us, but they sometimes made sense in light of what they knew.  Buried Alive doesn’t simply play off our fascination with the grotesque and death, though the book might not have been written if we lacked that fascination, I think it reminds us to approach our ancestors with a touch of grace and humility.  Maybe our progeny will show us the same courtesy.


 

If you’re looking for something for a younger student, check out this post→ from Joanne Loves Science or these recommendations→ from STEM Friday.  By the way, I also write about engineering, infrastructure and the environment at Infrastructure Watch.
