    "concept_summary": "Smith describes a device that uses a disc bearing multiple ceramic magnets and a specially wound ferrite-core coil (the \"Caduceus Coil\") to create a rotating magnetic field. By exploiting what he calls field-energy minimization and the orthogonal nature of magnetic field motion, the apparatus is claimed to generate virtual \"gravitron\" fields that alter the weight of nearby masses, as measured on a precision balance.",

        "It will take a kilowatt comfortably, without heating at all, and we know that it will work on 100 watts, but it wont work for us on 30 watts. It just gets hot on the lower power!",
