Where it comes from, where it goes

Petroleum, coal and natural gas combined to provide more than 83 percent of the energy generated in the United States in 2008, as the flow chart below illustrates. Meanwhile, three of the most talked-about renewable energy sources – wind, solar and biomass – combined to create just 12.4 percent of all generated energy. While more than 40 percent of all generated energy powered homes, businesses, factories, and our planes, trains and automobiles, 57 percent of it was rejected – or wasted as emissions or exhaust.

Q&A: Miners got game

What was the most memorable sports team during your time on campus? As part of his research for the S&T 150th history book, Larry Gragg, Curators’ Distinguished Teaching Professor emeritus of history and political science, asked you to share your memories. Here are a few of your answers.

Honoring new academy members

In October, 12 alumni and friends were inducted into Missouri S&T academies. Academy membership recognizes careers of distinction and invites members to share their wisdom, influence and resources with faculty and students. Some academies hold induction ceremonies in the fall, others in the spring.

Boosting cyber-physical security

A wide array of complex systems that rely on computers — from public water supply systems and electric grids to chemical plants and self-driving vehicles — increasingly come under not just digital but physical attacks. Bruce McMillin, professor and interim chair of computer science at Missouri S&T, is looking to change that by developing stronger safeguards […]

MXene discovery could improve energy storage

In spite of their diminutive size, 2-D titanium carbide materials known as MXenes are “quite reactive” to water, a discovery S&T researchers say could have implications for energy storage and harvesting applications such as batteries, supercapacitors and beyond. Their findings were published in 2018 in the American Chemical Society journal Inorganic Chemistry.

A faster charge for electric vehicles

One drawback of electric vehicles (EVs) is the time it takes to charge them. But what if you could plug in your EV and fully charge it as quickly as it takes to fill up a conventional car with gasoline? Missouri S&T researchers, in collaboration with three private companies, are working to make speedy charging […]

    Informative graphical presentation on pg 9, but I believe there is an error in the percentage of power generated by Wind in the US. If the coal graphic on the next page is correct, appears that the decimal is off, ie, the % contribution for wind power should be 0.845%, not 8.45%.
    Really enjoyed the series of articles in this edition. Hope you continue to feature important engineering topics in the future!
