Many noise generators produce noise greater than kTB by sending current driven by a voltage, the two factors of D.C. Power, through a noisy medium like a vacuum or gas tube, or semiconductor. The noise power is less than the D.C. Power. Such a beginning inevitably produces losses. Johnson Noise in a resistor does not require energizing D.C. electrical power. Mobile electrons in a resistor move at random to produce random radio frequency power. At a rectifying junction between N type InSb and a C60 Shottkey anode, more electrons can be conducted forward from the semiconductor to the anode than in the reverse direction. In a massively parallel system with all the anodes on a branch supplying electrons to a load and all the cathodes on the electron return branch, net current can be aggregated by a plurality of diodes at an equilibrium voltage supplying a higher power load.
