1. Describe the car and how it works.
The Grubby Express, a train shaped vehicle, is powered by nickel cadmium – chloride rechargeable battery that is used in real electric cars. The electricity provided by the battery is used to power 2 motors that run the car. The stopping mechanism is an organic clock timer called the “blue-bottle reaction.” This reaction is a mixture of sodium hydroxide, glucose, distilled water and methylene blue. When combined initially, this solution is blue. During this process methylene blue is reduced, becomes colorless and forms leucomethylene blue. With a photo diode that is placed under the flask, we can detect when the solution becomes colorless and stop the car.
2. When and where is the regional competition?
The AIChE Regional ChE car competition is April 1-3 in Golden, Colorado at the Colorado School of Mines.
3. Describe the competition.
The goal of the competition is to have a car that is started and stopped with a chemical reaction travel a distance between 50-100 feet and carry an amount of water between 0-500mL of water in a 2 minute time limit. We are told the distance our car must travel and the amount of water our car must carry an hour before competition.
4. Who is on the team?
On the team are Ben Bangasser, Scott Connor, Derek Gouldin, Dave Stotz, Bridget Fiegen, Ashley Johnson, Taffy Kempton, Kristi Murphy, Isaac Himanga, Patrick Buyck, Kristen Bartelt, and Nick Stehlik. However, only 8 students from the team are traveling to regionals. They are
Ben Bangasser, Scott Connor, Derek Gouldin, Dave Stotz, Bridget Fiegen, Ashley Johnson, Taffy Kempton, and Kristi Murphy.
5. Why is this competition important for students?
This competition is important because it teaches hands-on engineering application that students don’t get in lecture. It also allows us the chance to see what other schools have to offer in our field and get a different perspective on our respective majors. This competition challenges us to be the best in the nation and demands us to uphold the well-known SDSM&T reputation of excellence.
6. Why is it important to science? This competition is important to science because it familiarizes the students with up-to-date technology and allows them to work with that technology. Science is benefited by the growing minds that our competition is shaping.
