    How did it take so long for the algorithm to show me your channel? Love your take on electric/electronic/physics history.
    One thing I am curious about and can find any videos for, is the process of converting a city from 25hz to 60hz.
    My electricity teacher mentioned it when I was in school but I didn't grasp how big a project like that was at the time.
    He was referring to Toronto but there must have been many cities that had to do this. No hurry your going through a sensible timeline right now.

      Awesome question. I work in the power industry and collect artifacts across the paradigms and have a 25hz motor but in poor condition. So many decisions we've forgotten had so much impact on our society today. Like the comment before yours, from Lasselucidora, I too greatly love this channel and Kathy - the way she presents the history and physics is fresh and enthusiastic. Perfect for the youth getting started like I did in the 70s.

    My story will date me. As an undergrad EE I worked for the physical plant department. The original buildings on our campus were constructed in time for the 1904 World's Fair and were powered by the "original" 2-phase, 90-degree out of phase system. When the world came to realize not long thereafter that 3-phase power was the most economical the university, not wanting the expense of replacing all the 2-phase motors, installed two center tap transformers in a "Scott Bank." to power them. By the time I was there (1960s) there were only two motors left running off the Scott Bank -- one large exhaust fan and the book elevator motor in the original library. I had always wondered why 2-phase when I think it was on page 2 of the introduction to A/C circuits book that demonstrated the economy of 3-phase. Thanks for helping me to understand the natural progression.

    an AC motor is very important because if you simply reverse the force or energy applied then it becomes a generator. if you input electricity it spin if you spin the rotor it will create electricity. Ferrari was a genius. Ferrari's model is still the basis of modern AC motors. force input = force output almost of course there is very small loss due to mechanical movements of the parts or loss due to heat.

    I love this channel. I'm an electrician and since I started I've looked at the history of wiring methods and materials. I regularly work on wiring that's 100 years old, and if you date the wiring, you have an idea of how the entire premesis is wired.
    These histories are awesome, and it would be super cool to cover somewhat in-depth the methods used in various types of construction. How did knob and tube come about? How did we change from transmission lines in the walls to cloth and tar cabling? When did NMB cable go from black to white to getting color codes? How did Edison standardize equipment?
    Just cool things I have stumbled on.

      @Jakov Jerkovic 😂😂😂 dood you are so unbelievably misinformed. Did you just say Tesla had nothing to do with electric cars or using his electric motors for transportation?!? 😂😂😂😂😂😂
      Go look up Tesla’s TRAIN car patent. It uses a high frequency AC source and high frequency ac motor. WHICH COULD BE USED IN REGULAR CARS TOO……and he says so in the patent too 🙄🙄🙄
      Electric railway system PATENT # 514,972…..
      Not to mention… Tesla literally had a patent turned down for a car that is powered by his Tesla turbine that spins a high frequency alternator from which the high frequency alternator is rectified and used to directly supply power to independent electric motors around the car. This patent of his was turned down. Go pick up the “unresolved patents of Nikola Tesla” and learn yourself something before regurgitating the nonsense you just spewed again 🙄🙄🙄

    • @CharlieSolis
      @CharlieSolis 2 роки тому

      @Jakov Jerkovic even worse what you just said is a clear indication that you haven’t read barely any of Tesla work because he explicitly talks about how he wanted to use the AC induction motors for flight because it was the only motor at the time that as light enough to even think about flying. And with his desires to wirelessly transmit power he fully envisioned his AC motors being not only powerful enough to keep flight sustained but also have the power transmitted to the plane that their was no fuel needed to be carried with it….. “even though tesla had nothing to do with electric cars….” 😂😂😂 yeah ok bud.
      Stop confusing the fake claims of Tesla’s “batteryless” car by arther Mathews and Peter savo as “proof” Tesla did no work at all on electric vehicles 🙄🙄🙄

    • @CharlieSolis

      @Jakov Jerkovic Tesla is not a god and he got some things wrong, and the entire 3,6,9 crowd is predicated on a fake Tesla quote. But that does not make Tesla’s own works invalid just because their has been a concerted corporate effort to sully his name and ideas 😂😂😂 I have literally found paid disinformation trolls on the internet who actively run around spreading fake fantastical claims of Tesla just to keep people thinking it’s not worth even looking at his work because he “was a kook” and he was too cool for school… 🙄🙄🙄

    • @CharlieSolis
      @CharlieSolis 2 роки тому

      @Jakov Jerkovic “he took an assistant and did nothing in AC motors!”
      Umm what?!? Both of Tesla’s high frequency alternators/generators, patent numbers 447,920 and 447,921 filed in 1890 can be used in reverse as AC motors……🙄🙄🙄 they just aren’t self exciting. But Tesla also patented a self exciting DC generator/motor, Patent number 406,968, that could be used as the simple exciter that fixed a vast majority of the issues with the Faraday disc…

You could shove an aluminum plate in there standing on edge, and the induced current kept it upright for quite a while.

    Looking forward to your video on Steinmetz, whom I knew about in a library book in high school, when I had never read anything about Tesla. Something I attribute to GE having more publicity and promotion in schools available. In Jr. High I made a "computer" according to a GE Progress Poster plan that won three blue ribbons at Science and County Fairs. It was a very simple analog resistor multiplier circuit, that I added two rows of push buttons to, numbered 1 through 10. Digital computers were in all the news in 1957, and in my innocence I did not know one type of computer from another.
    Getting the ammeter on that analog computer to read the correct answer to two simultaneously pressed, numbered buttons, wired to the appropriate spots along two linear nichrome wires was a nightmare, as each clip altered the total resistance. Anyhow the learning experience was invaluable to my later career in aerospace.

    The Italian 30km energy transfer from Waterfall Lanzo to Turin was in 1884.
    The transfer from Lauffen to Frankfurt was later in 1991.
    So the Italians were much earlier (even Germany had a longer distance)

    • @Kathy_Loves_Physics

    It is often the case that when all of the elements of the basis for an invention come together, people with access to the same information will simultaneously and independently bring them together to invent similar, if not identical things. The one who gets the credit is often just the one who happened to decide to patent it or promote it. And many vested interests or promoters get to write the stories that we learn in history books. As an electrician, this has been such a great romp through this fascinating history of the meeting of physics and our material technology.

    • @Grandpa82547
      @Grandpa82547 2 роки тому

      What the history books told us is amazingly inaccurate in many cases. (particularly in American history books). Who gets credit often depends on who got to the patent office first, who had the best (or most unscrupulous) lawyer, who had the most money, or who got to market first, etc. We have often given credit, not to the true inventor, but to the one who made the most money. American history is, in large part, the history of raw capitalism.

    absolutely fascinating: as a lifetime engineer (i tend to build things to see how they work)...i can state: kathy does a wonderful job of explaining *how* one of the most important inventions in human history happened. (namely the phased induction motor - really a generator of electrical power).
    ferraris' work on "multiphase" light (polarized light) is absolutely crucial here, since there is a connection between electricity and light waves (both part of the electromagnetic spectrum). do we fully understand the potential of the full electromagnetic spectrum? no... is it worth exploring and designing experiments that reveal the secrets of light? yes... i would encourage any scientist or engineer to consider this course of action. since, what's next?
    whats the new generator (beyond polyphase generators), based on real scientific discovery, gonna look like?

    Like several other people here, I too just learned about your channel. Also, like several other people here, I too have been reading about and studying Tesla's works and the things attributed to him. Over the past few years, I've been running into other information about Tesla that tends to confirm the things you're saying in your videos about him - Namely that he was inspired by others but didn't give them credit when he applied for his patents or wrote his papers which were published in the journals of the day. Now that you're giving more dates and clarity to the events of those times, I'm becoming more convinced that Tesla, while a genius in his own right, may have actually been more inspired by others achievements than he ever publicly stated.
    I've signed up for your email list using a different email address, and am looking forward to receiving the chapter you've said you removed from your upcoming book. I'm also looking forward to being able to read that book because I have a feeling it will give more clarity to what actually happened during the years when "The Current Wars" were going on, and who did what and when they did it.
    On another note, I think purple looks good on you. Also, sorry to hear of the breakthrough infections you and your daughter are going through. I'm hoping you will recover quickly and will be back to full health in no time at all. Get well soon Kathy!

    Small bit of personal history... In the late 1970's I had to design a 6000 amp 250 DC rectifier from 3 phase AC. The issue was that it had to run on 25 cycle and could be converted to 60 cycle at a later date. The steel mill in Homestead, Pa, ran on blast furnace heat at 25 cycles. When they stopped melting ore, they had to change.
    25 cycle really flickers. 25 cycle was good for wear and tear on equipment.

    I'd like to hear your opinion on Heaviside. I know math people don't like it too much but it's really interesting (and works in industry). A diminishing integral always with a value of 1. It would be a good tale I think. Ignoring infinity(or time) is required for a bit haha.
    (Thanks for your videos, you do a really good job of these. As a fellow electric geek I really appreciate it, might give it a crack myself one day. I'm more on the software side but LOVE physics and history and have really been enjoying your vids.)
    Cheers.

    Back when I was building Tesla coils in the 1990s, the only people discussing Nikola Tesla were high voltage experimenters and free energy weirdos. I read all I could get my hands on at the time and the general assessment from the less sensationalistic authors was that Tesla was an unfairly forgotten electrical pioneer.
    Jump 25 years to 2022 and Tesla has gone from a unit of magnetic flux density to a household word. I wonder if current researchers are more inclined to harshly assess his achievements because of his recent leap from obscurity.
    Super happy to have found this channel. Watched a half dozen videos so far and just joined your Patreon. One thing you inspired me to learn more about is transmission frequency. Tonight I already discovered that there is an old New York hydroelectric plant that still produces power at 40Hz, that 133 Hz was not unusual around 1890, and that 33&1/3 and 16&2/3 were also chosen. Maybe some other content provider has a video explaining why early generators and turntables ended up rotating at the same speed. 😄

    I think the point is that you need a means to reliably magnetically attract a shaft to rotate. You can do this by a less than 180 phase difference in a nearby coil. The change in crests causes the shaft to go to the next coil.

  • @realvanman1

    I’d have guessed that the inspiration was drawn from the steam engine, specifically the two cylinder, double acting type as would be found on a locomotive, for instance. These have crank throws at 90*, are self starting, and develop continuous, nearly constant torque, like a two phase motor. I’m quite surprised to learn that this is not the case! They would have been literally surrounded by these engines in their time.

    • @Kathy_Loves_Physics
      @Kathy_Loves_Physics  2 роки тому +1

      That would’ve been a logical guess. Silvans Thompson gave that its an analogy in a book in 1897 or so (not sure of the year). However, that is not what inspired Ferrari’s and I think that If Tesla had been informed that way he would have said so.
