:::: N.T. Photography Density Pr. :::: #NiTePhDPresentation :::: " In February 1917, Nikola Tesla presented an extraordinary innovation: a colossal mercury interrupter capable of managing a staggering 50 horsepower of electrical energy, interrupting the circuit a remarkable 100,000 times each second. This was no mere circuit breaker; it was a meticulously crafted apparatus designed to adeptly handle extreme electrical demands with remarkable speed and accuracy. At the core of this intricate system was a formidable 50,000-volt direct current dynamo, prominently featured in the foreground of the accompanying photograph. Tesla relied heavily on this machine for his high-voltage experiments. Surrounding the setup were substantial capacitor banks (also called “condensers”), while the main attraction was a conical Tesla coil, which could unleash massive high-frequency, high-voltage bursts, radiating several feet in diameter. The interrupter itself functioned within a substantial chamber filled with mercury. Inside, a swiftly rotating cogwheel—powered by a motor positioned atop—generated a rapid succession of electrical contacts and disconnections. As each stud of the cog dipped into the mercury, it momentarily completed the circuit before swiftly severing it again. This ingenious technique enabled Tesla to harness immense electrical forces with remarkable precision. Originally conceived and utilized in his wireless energy transmission experiments around 1900, this device represented a significant leap in electrical engineering, pushing the limits of the field at that time."
Be.Ru.(1950)Chapter7@UNpopuLAr#ESsays:“There is not in Europe any such thing as a pure race. Russians have an admixture of Tartar blood, Germans are largely Slavonic, France is a mixture of Celts, Germans, and people of Mediterranean race, Italy the same with the addition of the descendants of slaves from every corner of the Empire imported by the Romans. The English are perhaps the most mixed of all. There is no evidence that there is any advantage in belonging to a pure race. The purest races now in existence are the Pygmies, the Hottentots*, and the Australian aborigines; the Tasmanians, thanks to the British, who were probably even purer are now extinct. There is a special absurdity in applying racial theories to the various populations of Europe.”
