    "goal": "Generate usable electrical power and heat through low-energy nuclear transmutation of zirconium oxide.",
    "problem_addressed": "Provides a compact, low-temperature source of electricity and heat; claims to also enable nuclear waste remediation via transmutation.",
    "concept_summary": "A tabletop reactor is filled with zirconium oxide and a liquid metal. Nanosecond electric pulses create an arc in the liquid metal, allegedly inducing transmutation of zirconium into iridium and palladium and directly producing electrical power and excess heat.",
    "detailed_description": "The reactor (table-top size) is pulsed with a nanosecond pulse generator. Electrical pulses travel into a cell containing a \"liquid metal\" and zirconium oxide. The arc generated in the liquid metal triggers a nuclear transmutation process that converts zirconium into heavier elements (iridium, palladium). The process yields direct electrical output as well as thermal energy. Demonstrations reported 100 W of input producing 300 W of electrical output plus heat; another claim is 60 W input -> 20 kW output.",
