Nicola Tesla is truly the definition of genius. Ironically almost a century later, in the early to mid 1990s, the induction lamp, and the electronic fluorescent ballast, and later on in the 2000s, electronic HID ballast, came into use. The modern induction lamp, for those that don't know, is a fluorescent tube usually shaped into a circle and excited by a high frequency induction coil, with no direct electrical connection to the lamp. Modern electronic ballasts typically operate in the 20k to 40kHz range, making them silent to humans, as opposed to the hum of older fluorescent fixtures with magnetic ballasts that operate at 60Hz (or 50Hz for many countries outside north America). Another often overlooked advantage to running the lamps at 10s of kHz, is the lamp phosphors stay excited during this extremely rapid zero crossing of the sine wave, giving a truly flicker free light. Old magnetic ballasted fixtures, although appearing flicker free to the human eye, can make rotating machinery spinning at multiples of the powerline frequency appear to be stopped; this is a serious safety hazard in places such as factories and mills.

Nikola Tesla finally got the frequency of his special alternators all the way up to 50 kHz, fifty thousand cycles per second. That was high enough to be considered RADIO, and he indeed used it to transmit radio signals, INCLUDING VOICE, at a time when all the other radio transmitters in the world were based on noisy and inefficient SPARK GAPS, suitable only for pulsed On/Off signals like Morse code. *Alternators similar to this are still used in some wind turbines* to transform the slow rotations into power at relatively higher frequencies, which are much more convenient to work with.
Modern fluorescent lights, especially those used for studio and stage lighting, are also driven by high-frequency electronic ballasts to prevent noise and flickering.
Before era of Henry FORD, Gasoline was mostly tossed away as useless by-product after/during Kerosene production process (for the older version of street lamps).. then Ford engine to power the Cars of massive scale, make gasoline (benzine; in German) widely used as main fuel/ commodity: far more than Kerosene used for the city lights/Lamps.
I thought those arc lamps were DC, if so, then I guess the noise was caused by the differing amounts of currents pulled by the arcs themselves during operation rather than the power supply?
@@set_simplified Some said that HF would have been a problem for the transformers and I would tend to think it might because of the type of cores they had then
The noise is produced by expansion from the heat of the arc. The polarity of the arc does not matter, both ways produce the same amount of heat. Furthermore, the wavelength of an arc is only the width of the arc itself, so unless you were exactly between two of them within the millimeter the sounds would not arrive at the same time. Maybe a thick glass bulb that is vented to the roof with forced ventilation...
WooW went trough a wormhole and jumped to a different dimension according to this video where power is 11 Khz and every light is running on arc lamps quietly thanks to tesla.🤣
We now use solid-state electronics for frequency conversion, whereas power distribution still uses 50-60Hz and high voltages with multiple step-downs toward the user end due to the "low power loss over distance" as we have for far too long. I believe the innovation needed in this area involves decentralized generation and obsolescence of the power grid and monopolistic power structure that created it. In fact, we have moved further away from local independent power generation excepting photovoltaic, with the removal of so many small hydro-generating facilities, and have been effectively banned from building new or re-building old ones. Photo-voltaic fields are a joke in comparison of cost-effectiveness, efficiency, and environmental impact, although gov't/industry collaboration will lie to you about this while they reach deep into your pockets. If dc tech is all that's available or convenient on an individual level or close to it, oscillating (or alternating or digital) currents can easily and efficiently be created for most apps by a pocket-sized inverter, but kinetic rotary generators are still best as ac sources.
Dogs hated it. Seriously though, was this ever actually put into use? I can foresee problems with transformers, and possibly other electrical devices being hit with what is essentially a radio frequency at hundreds of amps.

Very interesting innovation...
Like I Said: Innovation , "Is the Mother, we are only at our Better when things go Wrong, what's the Moral , Keep looking Up !
I never knew arc lamps were once noisy. Thx
Lots of excellent graphic work thanks to all !

Fluorescent bulbs also work better at higher frequencies. Electronic ballasts run in the 40,000 Hz range.
Good to create free energy generators. 👍🏼
Nothing is free ,anles you neglet
That is cool
Who knows maybe there are Teslas today in the same situation … N..
I wonder why didn't we switch to 10 kHz for good?

Initially Arc lamp were powered by DC , but latter it was powered by AC also.
@@set_simplified I am thinking at first they would have been powered by Edisons Electric in the US
@@set_simplified Some said that HF would have been a problem for the transformers and I would tend to think it might because of the type of cores they had then
Isn’t 10kz still an audible frequency?
Frequency depends upon Arc Size.. Read the document present in the video

So why not reverse the phase of each lamp in the string? Phase nullification. You would only hear the noise at intervals between the lights.
The noise is produced by expansion from the heat of the arc. The polarity of the arc does not matter, both ways produce the same amount of heat. Furthermore, the wavelength of an arc is only the width of the arc itself, so unless you were exactly between two of them within the millimeter the sounds would not arrive at the same time.

Arc is hivoltage balast

Those lights aren't nearly as annoying as you may think.
Once we create a laser that can produce a 280 ,000,000 pulses per second beam we will be able to create anything, even life.
Where's my 48 hours of arc-lamp youtube ambience video?
kindly explain what are u saying Dear viewer ?
@@set_simplified We have 48 hours of Lo-Fi chiptunes videos we can play all day long, I think we should have the same thing but with carbon arc lamps.
Absolutely @@set_simplified
tesla trying to invent DC? wait what? ac just becomes a dc signal at high enough freq i thought
That's not true.. Because transformer can function with this high frequency AC current but not DC current
This solution may only work for local generation and consumption. God forbid if you need to deliver the power at 11kHz even a few kms away.
It will work for long distance also..
@@set_simplified Yeah, it will. Like a huge antenna.

easy ....nice lol
Thank you Dear viewer
Large diameter, many poles, high RPM, that's it. Saved you eight minutes and sixteen seconds. Alexanderson did it better (but later).
Dogs hated it. Seriously though, was this ever actually put into use? I can foresee problems with transformers, and possibly other electrical devices being hit with what is essentially a radio frequency at hundreds of amps.
A 10KHZ power would create more problem than Tesla tried to solve.
Brother frequency was dependent on arc size.. Read the document which i have attached in the video
