The most frightening situation for a firefighter can be getting lost in a smoke-filled building. But, three students at the University of Wisconsin-Madison, hope their invention will stop that situation from ever occurring again. Nick O�Brien of Apple Valley, Chandler Nault of Bloomington and Mitch Nick of Green Bay, Wis., designed FireSite and won the $10,000 first prize in UW-Madison 2005 Schoofs Prize for Creativity competition.
