CB:"The most important question on this topic is if Johnson Noise, thermally excited thermal radio frequency power, can be rectified and then the rectified output of many diodes in consistent physical orientation parallel can be aggregated for an external electrical load with the load imposing only the proper burden on the supply."
Aha, so this is what you assume your current generating mechanism is for your diodes.
Well, there is only one (fundamental) problem with this. The "Johnson noise mechanism" is not a current generationg mechanism in a junction. It is an effect of the resistance/impedance on the current flow. ALREADY EXISTING current flow. And it produces fluctuations in the already existinc DC?AC current.
As I said before, the Johnson noise appears because the electrons "hit" the ions in the wires, resistances, etc, and instead of flowing straight, their flow is perturbes by these "colisions" with the ions. It is similar to the way an athlete has to go through a bunch of swinging tires or sandbags. Instead of running straight the distance, he is hit ny the swinging bags, and runcs much slower, and with much more energy consumption. Furthermore, this noise is random, so it has no DC component.
There are only a few mechanisms generating carriers in a diode: photoeffect, biasing, thermoelectronic (Richardson) emission. And as far as I know, all the applications for these effects have been developed almost half a century ago.
If indeed you want to harness heat from the environment, the best bet would be photodiodesdiodes for the optical and far IR spectrum, so that they can take the heat and transform it into electric current. But then these are avenues already already explored by the solar power "people".
So no, with this mechanism your diodes won't do anything aong the lines you say they would. It ain't working that way.
