Dick McCarthy (left), maker of Richard Gray's
Power Company, and Doug Schneider hold the little squishy light bulbs that Audio Line
Source was handing out. The company uses a light bulb as part of its Edison Test to show
the effectiveness of their product. While some may consider these little lights
"stress relievers" of some sort, McCarthy was quick to point out that their
purpose is to "show how power could be stored and released."
