Art Bell interviews Bonnie Crystal, a Silicon Valley CEO and pioneering technologist who co-founded the first woman-led company to go public on NASDAQ. Crystal invented video noise reduction technology that revolutionized satellite television and developed a new flat-panel display called High Gain Emissive Display. But the heart of the conversation centers on her lifelong passion for exploration speleology, the science of venturing deep into the Earth's uncharted cave systems.
Crystal describes vertical caving expeditions reaching thousands of feet below the surface, where teams of four navigate pitch-black passages using specialized rope techniques and carry three of every essential piece of equipment. She details her invention of through-the-rock cave radio communications using low-frequency magnetic energy at 185 kilohertz, allowing contact with the surface from deep underground. The discussion covers remarkable discoveries including blind fish, spiders as large as a fist, bipedal lizard tracks from an unknown species weighing up to 20 pounds, and microbes found in Lechuguia Cave that NASA scientists study as analogs for potential extraterrestrial life.
Art and Bonnie discuss plans for her upcoming month-long expedition to a remote area of the Andes Mountains in South America, where limestone formations suggest caves could reach depths approaching 15,000 feet. They agree to attempt a live ham radio link from the expedition's base camp during the trip.
