Ken,
I can't help but consider what value bismuth might have in circuits in terms of negative resistance, given its high dielectric permittivity. Really enjoyed your exposition on it.

Its ODD you just mentioning that, me and a buddy just got off the phone.
We are ordering (price checking now) 1000 to 2000 pounds of bismuth.
The device is called an "electromagnetic detector and amplifier" and consists of a series of bismuth plates stacked in a pile and interlaced with copper wires. The bismuth plates are protected by a coating of sulfur because bismuth, a very brittle substance, is likely to crumble.
Further to my above comments, the question arising for me regarding bismuth crystal's high dielectric permittivity is how it behaves relative to other crystals, such as quartz, for example. We know that quartz is used to amplify energy. Now does quartz cohere dielectricity or does its energy amplification have more to do with a pulse or pressure (in the case of piezoelectricity) causing the crystal's own molecular bonds to release energy. Ya nye znayu
Anyway, I'm no expert on crystals - haven't researched them. However, if bismuth is high in dielectric permittivity, will its crystals perhaps cohere dielectric energy as they are pulsed?
Now here's a strange thought...
Since they changed all the bird shot from lead to bismuth, and bismuth has higher dielectric permittivity... Suppose a hunter shoots two geese. Now these two geese meet up with another goose who accidentally swallows a magnet. Now these three geese decide to fly south. Funny thing though, the geese who have the bismuth pellets lodged in their tissues feel lighter in air than they used to. An ordinary goose would pass it off as an endorphin rush from euphoric anticipation of a warm vacation in the sunny south. But these are Canada Geese - they know something's different. The other goose still has a neodymium magnet lodged in his gizzard. He feels sluggish, and frankly doesn't believe he'll have enough goose juice in him for the trip south. But one day the three old goose pals are flying in tower formation - that is, one above the other, and the neo mag goose is flying with a bismuth-loaded goose above and below. He feels the levitation, and he makes it to Florida. But then an alligator gets him and can't seem to get himself unstuck from the sewer grate in Pompano Beach.
What's the moral of the story?
Edit: And as the goose with the neo in his gizzard succumbs to the alligator's grasp, he blurts out these final words to his bismuth-laden friends: https://www.youtube.com/watch?v=UAk9...etailpage#t=34
Better get back to work.

Reason: Further elaboration of narrative.
One of the more interesting rectifiers was used after World War II. Developed in the 1930s, the selenium rectifier contained a stack of several steel or aluminum plates coated with bismuth or nickel, with a thicker layer of selenium and a halogen element added. Each plate could typically withstand 20 to 22 reverse volts and the voltage rating was easily increased by adding additional plates to the stack at the time of production. Selenium rectifiers were more efficient than vacuum tubes but unfortunately, they had a shorter usable lifespan and could not be easily replaced by the end user. By the 1970s they were replaced by the smaller, more efficient and reliable silicon diode, which was much cheaper to manufacture.
