Inside a lab at the Vanderbilt Kennedy Center, Reyna Gordon is holding up a tangle of elastic wires connected to electrodes.

“For the kids, we call it a spaghetti hat,” she says with a laugh.

Todd Oney with the Nashville Electric Service is pointing to a utility pole next to I-40. There’s electricity at the top, then telephone at the bottom, and in the middle, three black cable lines.
