The lab is in the engineering wing of the Cooper Union, known also for excellence in architecture and art. Inside, there's visible evidence of all three disciplines: Each step on the stairs looks like it's a different length, and the elevator is lined with medieval chain maille. As I make my way upstairs, Greg Loibl, the lab's head and Michael Gutierrez, manager of R&D, explain that they just moved all of their equipment into a new room. There's plenty of wire and tubing scattered around. A fridge stands in the corner next to tanks of water, predictably. On the tables are some of their latest projects and, in one corner, the Cooper Cooler.
