Sounds of thundering engines roared around the perimeter of the normally tranquil Discovery Greens in Downtown Houston, Texas. From afar, the scene resembled a Formula 1 race: cars boasted corporate sponsor decals and swung through the turns passing on the inside as they jetted off towards victory. Well, it really wasn’t quite like a Formula 1 race, but for the chemical engineers on the scene, the Shell Eco-marathon was far more exciting.

More than 1,000 students with 113 vehicles from high schools and colleges across the United States met in Houston to compete in the 2012 Eco-Marathon Americas competition, now in its sixth year. Students were challenged to drive farther than their peers on one gallon of fuel using any of the following technologies: diesel, gasoline, ethanol, FAME, solar, hydrogen and electric battery technologies.

The Shell Eco-Marathon aims to promote the spirit of competition as well as engineering problem-solving. Over the weekend, the students came face to face with their competition to duke it out on the race track and decide which schools were able to design the most fuel efficient vehicles. The pictures illustrate just how creative some of the designs were.

Here are just a few of the winners' achievements by:
2188.6 miles per gallon gasoline (Mater Dei High School – Evansville, Indiana)
A run (10 laps) of 611 miles per gallon gasoline (Mater Dei High School – Evansville, Indiana)
488.7 miles per gallon diesel (Louisiana Tech University – Ruston, Louisiana)
For more information on the results, see the Sunday Wrap Up Page.
This year, the Eco-Marathon also happened to coincide with the AIChE Spring Meeting and 8th Globlal Congress on Process Safety. The concept vehicles were special treats for those attending the conferences.
The AIChE Foundation raises funds to support projects and activities that further the Institute's mission and enable the profession of chemical engineering to have a greater impact on the world. Donations small and large make a difference.
If lead-lag systems still puzzle you, or you need a quick refresher on the subject, check out the latest chemical engineering tutorial in the Learn ChemE series.
This tutorial introduces lead lag systems, with a particular focus on first-order systems. The tutorial was made by faculty at Lafayette College and, like the entire Learn ChemE series, produced by the University of Colorado Boulder, Department of Chemical & Biological Engineering.
If you're looking for help with other process control subjects, be sure to peruse the latest titles in the series' playlist of process control tutorials.
