    I just retired from a 40 year career in electronics at HP's Test & Measurement Group and Intel. I just moved to Bellingham and part of my retirement plan is to volunteer at the Spark Museum. I've visited it multiple times previously and it is a great museum for people who love electronics and the history of electrical inventions. I'm glad you gave it some well deserved visibility to a wide audience! There is so much more to see there that you just barely scratched the surface.

      It surprises a lot of people! It's actually safer to handle older books with clean, dry hands than it is with gloves. Gloves are only necessary if you are worried about mold or other substances you wouldn't want on your hands.

    In Munich we have the „Deutsche Museum“ which shows tons of technical stuff if the last 2000years. And since the 70s there is one room named „Hochspannungsanlage“ high voltage unit, where the Faraday experiment has been done every day at 2pm (AFAIK). Up to 1MV and up to 1kA.
    Unfortunately the close that part for renovation for some years. I was there decades ago, but now, close to 60, I definitely have to visit it again. Not like last time as a (part) day during a holiday trip with my parents, but for multiple days.

    Many years ago while pursuing a degree in electrical engineering at Oregon State University I took a class in high voltage from Dr. Lewis Stone. The class included a lab where professor Stone set up an overhead conductor to operate at 220 kV 60Hz. I was one of 4 students in the lab where Dr. Stone, with only his flash-light, lead me from my desk to beneath this conductor. He then instructed me to raise my hand toward the cable where I experienced the electric field. As my hand approached this cable corona discharge developed from my finger tips. It was an amazing experience and your video reminded me of this. Thank you I love your videos!

    About 40 years ago I visited the Deutsches Museum in Munich. including seeing a fantastic high voltage demonstration. They had a Faraday ball where the fellow would get in and they would hoist the ball in the air and then zap it. There was also had a demonstration on lightning rods for building protection. As I'm interested in electronics, I didn't have a problem understanding the German specialized vocabulary. The Deutsches Museum has a website in several languages.

    Hello Kathy, I'm 74 yrs old now but back my 20s I built a pretty big Tesla coil once from plans I saw in Pop Electronics or some thing. It was powered by a 15,000 V neon sign transformer, had about a 40" long 5" diameter secondary coil. When it was running it was pretty scary with that 15K transformer running a pretty large and loud spark gap. I never could get the courage to let the main arc touch me even though the secondary had a larger air gap between it and the primary. The sign transformer failed and I only saved the secondary which was a pain to build and finally unwrapped it to use the large plexiglass tube for some other project. I think I wanted to build a large Van-De graph generator but never found all the materials needed.

    What is often forgotten in science, and we can see that with quite a few discoveries from the past century, that the ones that actually discovered it could very well have been someone else. Taking credit for it because you were the head of the lab or the husband of the wife who did it, happened often. I also think many of these were discovered quite a few times in the years before the publication, but never wrote it down. Would make a lot of sense as writing and publishing was only there for the wealthy. I always imagine the many bright minds who did experiments at home and never got to that stage.

    Lovely video, neat that such a place exists... but I have to ask: Have you seen "Arc Attack" (a band) play before? I got to see them at the San Mateo Maker's faire back a long time ago... they have TWO very large Tesla coils that are audio modulated and they perform live music with them... on the stage the front guy wears a metal suit (grounded) it's like a portable cage of doom... that attracts the massive bolts and he dances with it... or later on, he plays the electric guitar in the suit while attracting giant arcs across the stage. It is electrifying to say the least! So I won the raffle to buy a little Arc Attack Tesla coil kit... and I got to meet the lead person and got to go up on the stage and see those MASSIVE Tesla coils towering above me... yes, they were turned off, made me nervous... but I've never been in the cage of doom, but they do have one in their performance and they got Adam Savage (Mythbuster) to go inside and be ZAPPED by both of their Tesla coils while performing a song... like the cover of a sci-fi song, I think it was either the Dr. Who Theme or the Imperial March from Star Wars... The massive arcs singing the music... how cool is that?

    I have brand new books that discolor rapidly from skin oils in just a few years, so I’m curious as to why they aren’t having you wear gloves while handling something so special and irreplaceable. Otherwise, yes, what a special experience that must be.

    The museum should reproduce all historical publications in a manner that they appear original. Their sale would bring in income and allow people to "own" a bit of history. But why stop there? Sell kits for apparatus, too.

    Also, there‘s no way the Tesla coil‘s output voltage was 4,5 million volts! That magnitude would produce a spark 22,5 meters in length. I‘d like to know how the guys came up with that value.

    • @johnjenkins6829
      @johnjenkins6829 2 роки тому

      1) Jeff Parisse, the coil's manufacturer, told us;
      2) The rule of thumb I've always subscribed to is 30Kv/cm, or 76Kv/in. 4.6M/76K = ~60", or 5 feet.
      What method do you use to calculate the 22.5 meters?

      @@johnjenkins6829 Hello, John! My source is Greg Leyh (Lightning on Demand) who told me in person, that from his measurements, the breakdown of a high voltage, high frequency spark ⚡️ is 200 kV / m. You can use 200 kV / 40 in to get 5 kV / inch or 60 kV / foot.
      Greg has built a 40 story tall Tesla coil & has demonstrated it very often & annually at the Wardenclyffe Science Center in Shoreham, NY.
      His coil develops 3 million volts and produces discharges 15 meters (≈ 49 feet) long …
      So the above rule of thumb is what I use, until it is found to be wrong.
      And … Since he’s built the biggest Tesla coil in the world (to date), I believe him!
      A high frequency spark ⚡️ is a completely different animal compared to DC & low frequency (mains) discharges.

      @@williamfox8795 Spark length is very unreliable method for estimating TC output potential. aprox 76 kV/inch holds well only for:
      a) Uniform E-fields
      b)Static E-fields
      None of that is fullfiled for TC coils. But rule of thumb is not to exceed 400 kV/meter of voltage gradient for a tall secondary coil form if you want to avoid flashover, arcing between sec-primary etc. Size always matters. In this case the size of Tesla secondary coil🙂. 3 MV coil you're referring to is about 40' tall

    With a book that old and rare why are they not handling it with gloves? It should be kept in a temperature and humidity controlled environment.

    • @johnjenkins6829
      @johnjenkins6829 2 роки тому +1

      From the Library of Congress: "Though clean gloves prevent the transfer of natural skin oils to paper, they reduce tactile sensitivity and increase clumsiness. Studies have shown that skin oils can affect how paper ages, but some preservation experts prioritize reducing the physical risk from reduced tactility; see "Misperceptions About White Gloves / Fausses idées sur les gants blancs," [PDF: 192 KB / 14 p] from International Preservation News."
      As the owner of the books in question, I choose to follow the science, and only require clean hands when handling the books.
