Tesla bragged about this: that he had created a generator that would last for five thousand years, have no moving parts, and had no prime mover! That's uncanny!
Well, ...
I suspect that, given the historical evidence, ...
# Tesla was ignored prior to World War II and considered to be a crackpot by our National Government. Unless he gave speeches, demonstrations, showed up at dinner parties, or wrote articles for publication in public media, he didn't get any recognition at all. Tesla was a nobody! It was only during WWII that our Federal Government took notice of Tesla due to the military intelligence reports coming back from the war effort which indicated that the Germans had the best of Tesla's technology making Tesla's existence hazardous to his health, namely: he could be abducted by anyone or worse, he could be assassinated, because he knew too much.
# This means that, once our United States government realized what a prized possession they had in their midst, all of Tesla's patents had to be immediately scrutinized for National Security.
Prior to WWII, we had two prominent inventors who did some miraculous things with their inventions. I'm thinking of: the Ammann brothers in 1921, and Nathan Stubblefield in the 1890s.
I usually like to focus on the Ammann brothers since they got far more publicity than did Nathan Stubblefield. Yet, Nathan may have replicated the device which Tesla bragged about, up above, by reading Tesla's patents. And all of this occurred in the 1890s approximately half a century prior to WWII and long before our Government hushed up some of Tesla's more fantastic patents.
It is said of Nathan that, although he was a poor and uneducated melon farmer from Kentucky, he had a voracious apetite for self-education. He read every electrical engineering book he could get his hands on. So, he was not under-informed. Not by a long-shot!
Well, ...
I have placed before you a simulation of what I believe is a replication of Nathan's handiwork and a replication of Tesla's boastful admission.
It'll give you a big surge within two and a half days of its start-up and then gradually lose power following the dictates of thermodynamic entropy.
But what a surge! And the best part, is that this surge will be sent into the Earth. Most of the nodes of this circuit are buried underground. Only a few, node numbers 2 and 3 surrounding the secondary coil, are exposed above ground. Also, the Living Tree which is acting as an aerial which receives a mixture of high, medium and low frequencies which naturally occur in our environment (along with the unnatural manmade frequencies) transfers these frequencies into its roots situated nearby the Primary and Secondary coils of the Transformer of this funky power supply. And the nodal voltages of this two and half day eventful surge do not affect the Living Tree a whole lot. The tree is sparred getting fried to death. This tree is acting as a sine wave generator, of sorts, in which ''any'' frequency is the right frequency to catalyze a surge.
And the best part is this ...
I ran a simulation of this over a span of 10,000 virtual years of simulator run-time! It's power level dropped by a mere factor of one million to one as it diminished towards zero amplitude of wattage on the Primary and Secondary coils. Considering that the initial wattage was just under a whopping 5e+160, I'd say it has a long ways to go before it dissipates all of its power, wouldn't you!?
And, since this device only surges once, if ever its operator had to “reboot” its powerful surge, all that would have to be done is to disconnect the Living Tree from the Primary and Secondary coils, or go plant another generator under the Earth!
