(KSL News) Students from 31 universities across the U.S. were at the Salt Palace today to see if they could make cars move without fuel.
The Chem-E-Car competition challenged engineering students to build shoebox-sized cars and power them with nothing but chemical reactions from things like water.
They had to move a certain payload a specified distance, but they didn't know those specifications until an hour before the competition.
Last year's team won with a car named "Coki" that was powered by a hydrogen fuel cell.
The top five winning colleges are as follows:
- The Cooper Union - fuel: baking soda and vinegar
- Carnegie Mellon University - fuel: copper zinc battery
- University of Oklahoma - hydrogen peroxide and potassium permanganate
- Louisiana State University
- Bucknell University
