Officer Tom McCloghry is a cop on the beat, patrolling downtown Columbia, South Carolina to keep the streets safe. And, though it's not so unusual these days to see police on Segways, this one is different. This is a hydrogen hybrid Segway, created with support from the National Science Foundation. In just the last few years, Columbia has transformed itself into a hotbed of hydrogen research--thanks in large part to the Industry/University Cooperative Research Center for Fuel Cells at the University of South Carolina.
