Electrical engineering professor Dr. Charles Van Neste and geologist-turned-entrepreneur Dr. Kaitlyn Suarez are proving that electricity can move straight through the ground—no copper wire required.
At Tennessee Tech University’s Shipley Farm, they’ve shown that electrical current can travel hundreds of meters through soil for a new way to deliver power safely and affordably. Their startup, Terra Watts, is now scaling the technology, with potential applications across sectors, from farms to factories.
“I still get excited when I see the lights flicker on in the field,” Van Neste said, still in awe of the design’s simplicity and its origins in Nikola Tesla’s early experiments in wireless energy.
A 2021 patent filed through the University’s research and economic development office, and supported by TTAC, continues to move the technology toward commercialization.
Now co-founders, Van Neste continues to lead the research driving Terra Watts’ future while Suarez heads up the business and also contributes in the lab.
“If scientists want their work to reach people,” she said, “they have to think like entrepreneurs. And Tennessee is the best place in the country to do that.”
