Carbon resistors generate more thermal voltage noise than Metal film resistors. That by itself proves nothing, but when applied to an antenna with radiation resistance we disprove the 2nd law of thermodynamics. Consider two experiments where the only difference is one uses a noisier resistor as a voltage source.
Preface: Radiation resistance generates no thermal noise. Experiment A: Resistor in series with an antenna. Thermal noise source resistance: R Antenna radiation resistance: Rr RMS thermal noise: Va RMS current: Va / (R + Rr) Radiated power: I^2 Rr = (Va / (R + Rr))^2 * Rr Experiment B, with noisier resistor: Resistor in series with an antenna. Thermal noise source resistance: R Antenna radiation resistance: Rr RMS thermal noise: Va * 1.1 RMS current: Va * 1.1 / (R + Rr) Radiated power: I^2 Rr = (Va * 1.1 / (R + Rr))^2 * Rr Experiment B radiates more power. Experiment B will be cooler than experiment A. Lets simply. Neither experiment A or B have a power source except thermal noise. Experiment B radiates more power. It is a very simple circuit. Over time, more energy is leaving experiment B than experiment A. Therefore experiment B will be colder than experiment A.
