Part 3/6:
During his experimentation, Hank originally used ceramic flash protectors to contain high voltage within the system. However, unexpected failures—where electricity bypassed the ceramic—prompted him to seek more robust alternatives. This led to the adoption of larger ceramic insulators, typically used in agricultural electric fences, which proved more effective under the conditions present in his tank.
Even with improved insulators, Hank faced another significant challenge: conductive soot settling on the insulation. This accumulation resulted in current leakage, necessitating further innovation.
