I’m still simulating. Every time I tried enter a realistic coil, the efficiency drops to such a degree that it’s below 100% efficiency. Is it possible to capture ambient thermal energy by means of magnetic materials with present technology? Till will tell. It will be interesting to see how the first legit perpetual motion machine is designed. Perhaps such a task will require room temperature superconducting wires.
The fundamental secret to ambient thermal free energy (term used loosely) is TIME! Simply stated, the rectifying element must be able to react faster (time unit) than the noise source.
Diode Example: The semiconductors transit-time must be low enough such that it responds faster than the noise source. For example, the SMS7630 microwave zero bias diodes have a transit-time of 10ps (pico seconds), thus giving the diodes response near 100GHz. The SMS7630 diode has a total capacitance of 0.3pF. If we take a look at the noise spectrum of the kTC noise from 0.3pF (Vn = sqrt[kT/C]) at room temperatures we see the thermal noise drops off far before 100GHz, meaning that the diode has far better response then it’s own noise. As to why the transit-time response is faster than the noise is answered by quantum physics.
One mistake made by scientist that I’ve talked to is in assuming the existence of ***white noise.*** In the real world there’s no such thing as white noise. White noise has infinite bandwidth. According to simplified theory, white noise is 100% unpredictable. IOW, the signal at any given moment could instantly change, and thus the rectifying element has no chance of rectifying the noise. Nothing could be farther from reality, as all noise sources even down to the fundamental free electron have capacitance. The thermal noise across a source is equal to the square root of kT/C, where C is the capacitance. There is no such thing in real life as “white noise.” Thus, the noise cannot instantly change from say 10uV to -7uV. The change occurs over time, and the rectifying element can react faster than the noise fluctuations. The diode, a dynamic resistor, can react fast enough to rectify Johnson noise.
2LoT (2nd Law of Thermodynamics) is a tendency, not a law.
