Northeastern Students Win Chem-E Car Competition

Remember the Chem-E Car Competition in Nashville we posted about earlier? Well, it looks like the team of chemical engineering students from Northeastern University have captured first place with their hydrogen-powered vehicle. The Aluminator, as the students named it, is a small car that looks like a toy but is actually capable of producing its own hydrogen fuel – pretty neat! [Boston.com]
