So finally after 2 years, the video is here!
Yup! I wrote a Hackaday article about it last year and that lead me to new ideas that made me try again.
@@RimstarOrg Where were you when I was in high school? If you'd been around to explain it then I might actually have passed sciences and physics
Wowww......
These have existed for like 50 years. If you really wanted to know how they work, you could have just Googled it
And 4 years later it’s still being viewed
Dear Steve,
I just wanted to take a moment to express my sincere appreciation and gratitude for the incredible educational content that you create on your channel. As someone who has always been fascinated by the world of physics and technology, your videos have been an invaluable resource for me in expanding my knowledge and understanding of these subjects.
Your ability to break down complex concepts and explain them in a clear and concise manner is truly remarkable, and your passion for these topics shines through in every video you create. I am constantly amazed by the depth and breadth of your knowledge, and I have no doubt that your work has helped countless others, like myself, to deepen their appreciation for the wonders of the universe.
Thank you for all that you do, and for your unwavering commitment to educating and inspiring others. Your contributions to the world of science and technology are truly immeasurable, and I feel fortunate to be able to learn from you on a regular basis.
With sincere thanks and admiration,
Caio Cesar.
I offer my sincerest gratitude for giving me a greater understanding of this aspect. May peace and prosperity be upon you always.
I like how you used a capacitor to represent the spark gap.
Outstanding, excellent! Thank you very much!
I was about to run away from this video half way through. So many educational vids like this go from simple elementary explanations to quantum physics equations in a matter of seconds. But this video was a steady incline of new information that even I could grasp after a few drinks. Thank you so much for this!
THANKS !!
Awesome video
NIce! I wanna make one so bad.
I made this video explaining how to make one using as simple parts as possible ruclips.net/video/puC6-UaT9Fk/видео.html. It's not powerful enough for a lot of the demonstrations shown in this video but it works. I plan on showing how to make one that is powerful enough though.
brillant!!
The best device explaination
Another great video.
Thanks.
RimstarOrg , WHAT WOULD HAPPEN IF YOU PLACED MAGNETS IN OPPOSITE DIRECTIONS IN BETWEEN THE PLATES ? WOULD THIS INCREASE THE GAP DISTANCE OR PERHAPS THE INTENSITY OF THE SPARK ? WOULD BE INTERESTING TO SEE
this would be great for a new kind of alarm clock.. one get up zap to wake you up for the rest of the day... 🤪 thanks a lot 😎
So how does a holtz generator work it seems less complex?
collecting and using not only collecting. you can run your bike ,car or house with this type of el.static maschine
Hi, just looking at the output created by a Wimshurst machine, the spark, is it powerful to charge a battery? I remember way back in Highschool we would dare someone to place his finger between the 2 balls and get shocked. it was painful as i remember.!!!
There's probably enough energy to charge a battery, depending on the capacity of the battery it may take a while. The spark is high voltage though, in the thousands depending on how wide the spark gap is, so you'd have to somehow lower the voltage to something just above the battery voltage. It would probably be easier to remove the spark gap and the Leyden jars and instead take the energy directly from the collectors, putting them through some sort of circuit to make sure the voltage is just above the battery voltage.
5:34 in real machine there is a sparks between disk and combs. Is it useful sparks or not? How to explain this sparks?
I don't get sparks between he disk and the combs on my Wimshurst machines. If you're getting sparks then that sounds like the points on your combs aren't sharp enough. If they're not sharp enough then charge will build up on them and stay on them, instead of cross the gap a little at a time. That will cause the electric field between them get stronger and stronger until finally the charge bursts across all at once. That's the spark. That's what happens at the spark gap at 7:52.
@@RimstarOrg Thank you for your answer. ruclips.net/video/4nOhlfeQNkQ/видео.html ... 3:57 is seems this machine can work with only 3 brushes connected to disks. How to explain this?
In that case he's likely producing charge from only the side that has both ends of its neutralized bar touching. I say "likely" because the brush for the neutralizer where it's not touching has sharp points and it's possible that that end is interacting a little bit with the disk through ionized air. If you look at a Wimshurst machine in darkness then you'll see the disks glow a lot with bluish corona due to all the leaking charge from the sharp edges involved (on the sectors and the brushes).
PS. RUclips flagged your reply as spam, probably because of the link, so I only just now noticed it.
Very nice animation. Did you do it in Blender? :-)
Thanks. And yes, I did it in Blender 2.71.
I just noticed your channel name. You've done a few fun things yourself!
Didn't the original Victorian machines used glass discs? Surely they wouldn't generate a charge in the same way?
If you're referring to glass and/or plastic disks with no sectors on them, some do still do it that way. I'm no expert on that type. My guess is that you'd need to have the neutralizers not touching the disks but be sharp points facing them across an air gap like the collectors. That way they can interact with a larger area of the disks than just what they would otherwise come in contact with. If they used surface contact then they'd only interact with where they touched because the glass or plastic doesn't conduct electric charge over its surface. But I could be wrong about how those work since I haven't looked into them.
@@RimstarOrg The one I saw was supposedly an original and had etched glass segments. I bought one of the Chinese reproductions but I was unhappy with the wibbly wobbly stand and the copper stranded brushes so I made a frame from lab materials fitted onto a mahogany base and replaced the brushes for carbon strands from HT ignition leads. I love scientific displays and your channel is very educational and clear. Check out my Jacobs ladder: ruclips.net/video/4eHp7AwKf7k/видео.html
@@RimstarOrg That's a very interesting thought, I'd be interested in seeing that experimented with!
ok interesting , how about adding a transformer between the two round electrode ark spheres with two more spheres connected to the transformer and have an air gap that the charge crosses through the transformer primary. This should create some pulse fed into the transformer and could be rectified into DC, essentially making the energy created into a useful regular electrical energy we are so accustom to in our world. Store the energy in a battery system . Add a large flywheel to the rotating system with a DC tickler motor that would keep a specific speed of rotation for the static plates having monitoring input from a micro controller. . The flywheel would want to keep the system in motion as per the physics laws. The DC tickler motor would kick in when required and use very little power to keep the rotation happening once the machine was up to cruising speed. Maybe we have an energy system that doesn't break any laws of physics? Your thoughts?
The electrical energy output of a Wimshurst machine is less than the mechanical energy input required to turn the disks. There's no violation of the conservation of energy here. In addition to that, it's actually a fairly inefficient machine since there are a lot of losses wherever there are ions crossing an air gap. The transformer idea still sound fun though, even though you'd have to wait for a spark before it does anything.
@@RimstarOrg oh you misunderstand... I didn't say it was a violation of the conservation of energy . I simply was thinking of adding a transformer with two balls of it's own and air gapped between the two arking balls presently in your machine. Then I believe the transformer would turn the high voltage power into useable power which could be rectified to DC and stored in a battery system. now also add a large flywheel onto the machine which suggests something in motion tends to want to stay in motion. Tickle that motion with a small DC motor from the battery system as needed to keep the machine speed constant. Would there be an excess amount of energy available? Of course you'd need a micro controller and sensor on the flywheel to control the DC tickle motor as well... perhaps a project for you to do and make a video about?'
It does sound like a fun project. I particularly like the idea of using the output of the spark gap as input to a transformer. It's pretty spikey output so I'm not sure how well that would transform, but it'd be interesting. You'd still need to hand-crank it to keep it turning, even with the battery/flywheel/motor.
@@RimstarOrg you'd have to make it a step down transformer for sure and bring the voltage way down as I'm thinking the spark across the air gaps would require at least 30kv or more. Figureing out a flywheel and where to put it on the machine also would be a task and of course I'd just use an arduino with a speed sensor to regulate the speed.. The pulse would be some sort of dirty square wave as my guess. Do you have an oscilloscope ? I'm totally new to the channel so appologize if it's a stupid question.
I do have an oscilloscope but I'm too busy with a robotics project to do this now anyway. It's an interesting thing to think about though. I also wonder about the speed of the voltage change that you'd get with a spark an whether or not the transformer core would be able to keep up. I vaguely recall something about the speed of the creation of the magnetic field in the core being a factor.
Kind of like lord kelvin's thunderstorm
One of the clearest and best-animated science videos I’ve seen. Fantastic!
thank you so much for all of your hard work to get me to understand electricity on the fundamental level. I really appreciate this channel a lot.
Thanks for explanation. It is clear and precise. Very amazing and beautiful. Saludos desde España.
So well explained! your animations really help
Thanks! You've made so many things that I can't remember if you've made a Wimshurst machine. That might be an idea for you.
It deserves millions of views
Going into this video: "Hey, no fair. You've already explained how a Wimshurst machine works"
Watching this video: "Oh. Wait. Nevermind. This one is GORGEOUS."
Beautiful job. Good editing, incredible animation, loved it.
Please don’t stop what are you doing 🙏 it’s really excellent work 🎩🎩🎩
Wow! I've come across your videos from time to time and after I saw the one you made about the tea laser a few years ago I checked out most of what you had posted. You never used to really attempt to explain things in this sort of depth and always sort of underplayed your understanding of things. I have to say that your explaining in this video is not only just as good as I expected, but the animations are perfectly synchronized with the script and very clear and well done in their own right. Did you do all the CGI yourself too? In any case I'm very happy to see your channel continuing to mature beyond what was already a fascinating catalog of fun projects and demos. I'm sure the algorithm fairy will bring you at least another 100k subs by 2020 if you keep this up.
Thanks! I'm glad you like it. I've done a few of these long, detailed explanation videos but I haven't done a lot because, as you can guess, they're a lot of work - 3 weeks fulltime for a single one. But I do enjoy doing them. Another one which I did a long time ago and which you might also enjoy is my How a Crystal Radio Works video ruclips.net/video/0-PParSmwtE/видео.html
And yes, I do all the CGI too using Blender, a free 3D modelling and animation software.
I think I can build my own now, after watching your other video on how to build one. I ended up knowing that you can use a film disk 📀. But I won't build one Cus. am lazy😅
I never thought such a complex subject could be explained so well. Good job Man
Thanks. It didn't happen often but every now and then I had the time to do a video with a thorough explanation like this. Another is one about how a crystal radio works ruclips.net/video/0-PParSmwtE/видео.html Thanks for watching!
Thank you very much for this video! Im from Brazil, and work in Musem of Arts and Trades, in Belo Horizonte. Here have a Wimshurts machine and i needed to understand better how works, and this video helped me so much! I really love it! Perfect explanation, i am sending for all my collegues, thanks!!
Thankyou very much for that informative video on the basic construction of a wimshurst machine.
I am an electronic engineer and have always been fascinated by this device ever since childhood when I used to see those old 1950s Frankenstein movies where they had huge ones made to show massive sparks which probably couldn't have been achieved and also jacobs ladder sparks which would have been unfeasable using them. But in all those years even though I understood the principle behind how the charge was accumulated, I never took the time to discover how they actually were constructed.
I'm retired now and plan to make a big one with the best insulators I can find and see what I can do with it...
Hey Amigo nice to see this video again...the Wimshurst video you made last time was one of the best !! I even tickled you to make an '' N machine '' after that i remember!
That's strange. You're the second person to say they've seen another Wimshurst machine explanation by me but this is the first time making one that I can recall. I made a start a few years ago but didn't get past the intro. As you can imagine, it was a monumental amount of work. I also wrote a Hackaday article but that's all.
yes i do agree this video was the epitomy of explanation about this device!! well done!
Probably the best WH explanation I've ever seen! Great job! And thank you! Wow that was good graphics too!
Where were you when I needed you in college?! 😁
are you still in college or in a hamster cage now amigo? ;)
fidel catsro hamster cage sadly
hmm... sorry to know that, then you might as well be a faraday cage and absorb electrical fields then..
To know how the wimshurst engine works is to know how the USS Enterprise is powered....
Same images.
I Have seen that one in an Electric museum in Denmark. Tange Elmuseum
How much watts (voltage and current) does it produce every second?
That's hard to answer. The voltage really depends on the distance at the spark gap. I did read somewhere that the current at the collectors is around 10 microamps or less though. Of course, if you have a spark then the spark contains a much higher amount of current over a brief time.
Excellent video presentation! I've subscribed to your channel.
ABSOLUTELY crystal clear SUPERB explanation . BRAVO indeed.
Bruh I did the stupid.
So I built your wimshurst machine (the DIY version), and it turns out that I literally put the neutralizer rods the wrong way.
I fixed it and got my first spark!
Some modifications I made are:
16 foils on each
Made of cardboard (no corona leakage as far as I can tell)
2 cylinder shaped Leyden jars
I'm glad to hear you got it working. Thanks for letting me know.
Awesome explanation, and 3d model!
Impressive. Cette explication est impressionnante de clarté.
One day this will be understood by all interested, without the confusion of charged virtual particles, using only the dielectric fields
I got two words for you...
USS Enterprise.
The man built ships alright...
A working model of the USS Enterprise..
Great video , as always. Keep the voor work up , for all oud Young people and alderly who want to learn
wow learnt a new word today: ...alderly!!!
Great video! Would it work if the brushes have higher surface area and are very close to the sectors, but not touching them tho?
Thanks! I recall seeing some with contactless brushes. I don't recall what the brushes looked like though.
best explanation ever, when it comes to physics, other dont explain as good as you
lol can you imagine seeing that 10 speed bike coming at you with this contraption.
:-) You'd definitely be wondering what it was.
Could you please explain, why does this machine doesn’t work in very humid places?
Humid air is more electrically conductive than dry air. That allows a lot of the charge on the sectors/segments leaks to the surrounding air and so it is harder to start the whole process.
Short : damp acts as a short circuit...
😊
wow this is awesome! i'm planning to buy this one for my lab.
Great video, excellent explanation. But you have forgotten to clarify an important point:
How does the tension in the Leyden jars continue to increase?
After all, the electrons in the increasingly negatively charged jar must repel the electrons from the collector at some point, unless the tension at the collector keeps increasing to overcome this hurdle (and vice versa for the positive charges).
The explanation for this phenomenon is hidden in the capacitor formula's:
The two opposite sectors (one positively charged and the other negatively charged, in your video the ones at twelve o'clock ) together form a capacitor with a certain charge.
The well known capacitor formulas are: C = εA/d and C=Q/V.
Rewritten: Q/V=εA/d.
(The capacity C, Farads drops out of the equation)
The permittivity (ε), the surface area (A) and charge (Q) do not change (no leak assumed). Now that those two sectors at twelve o'clock are rotating away from each other, the mutual distance (d) does increase sharply. As a result, the (negative) voltage (V) across this capacitor must increase accordingly, and is always higher (lower) than the voltage across the Leyden jar.
In theory, if there were no discharge at all (which is impossible) , the tension between the two jars could rise to infinity.
I built a Wimshurst machine myself a few years ago. Maybe I will make a nice video with a detailed explanation concerning the build and theory.
In the mean time you can see it sparking here: ruclips.net/video/QrFva1FmDhk/видео.html
Great video and description!
Hello again Mr. RimstarOrg ! , Sir, I think I sort of solved the sector scraping problem. My Wimshurst Machine used four metal spikes to collect the charges. Two for one side and two for the other side. I just took a pair of pliers and removed them and replaced them with some aluminum tape shaped like a flat point that brushes up against the disks BUT wouldn't dig into them like the spikes did. Sir, after solving another problem I had I have to say that I have waaaaay better ESD than before. Its like the day I first got the machine. Good as new ! Okay, now I'm going to see if I can make a Wimshurst Machine FROM SCRATCH! The one thing this improvement to my Wimshurst Machine has taught me is that I should NEVER be afraid to experiment scientifically with Ideas and things ! If I can make a Wimshurst from scratch then I can make multiple units and drive them all with one dc motor and interconnect them with gears. At that point, "Skys' the limit" because I will be able to generate any amount of high voltage. I thank you sir for your videos, they're really helpful in mullng thins over in my mind. I hope I can talk like this with you from time to time, thank you again.
thanks for your video ;finnaly I understood how wimshurst machine works....I heard about brushless machine called bonneti machine ..would be great to se a movie with explanation how it works...here is some papper about bonneti machine www.coe.ufrj.br/~acmq/bonetti.html thank you again ..I just subscribed to your chanell ..
Excelent explanation!
Great explanation and awesome animation. Well done!
Thanks!
Perfect explanation. Thank you, sir.
Thanks from Brazil. So... why do you need the Leyden jars instead of solely conect the colectors to the spheres?
The Leyden jars are for getting bigger sparks. They collect additional charge so that when the spark gap breaks down, the spark will have more charge (current) and so will be bigger and brighter.
the secret is hidden right here, in plain sight. This is the same machine that starts up a Flux Liner (Black-Opps electro-gravitic vehicle), maybe a bit more sophisticated, but same idea
Thank you so so much for taking the time to make this video, and all of the others that you’ve posted!
This is one of the best science videos i have seen so far.
I am so greatful for this great video with the perfect balance of explanation and observable reactions happening. Thank you I have only been able to get this with this video
You explained it pefectly!!! Awesome video!!
wow really good explanation! I've always wondered how that worked. I've heard in the invention of X rays, the Wimshurst was used to generate high voltage for the first X-ray tube - still somewhat in its experimental stage
fantastic explanation mate. For all those who don't get it ... its all about shed tech, when high tech was something you could build in your shed! Today high tech is microchips and programming ... difficult to build in my shed!
Wow!!!! Amazing demonstration, thank you (thank you!) so much for taking the time to do all this!
It's so much fun I am so excited to one day build one of these to experiment and play around with they are so cool!
Hi, Can static electricity be harvested and used for high power use ?
In my experience, no. There isn't usually much power available when you generate static electricity. When there's a spark there is but then you have to wait to build up for another spark which makes it not much power overall. Regarding this Wimshurst machine, the power output will always be lower than the power you use to turn the crank. And since Wimshurst machines have a lot of losses, they're also not very efficient.
@@RimstarOrg Thank you . Do you think that " spark" would bust the water molecule ?
I don't know.
Yes ..see : star ship enterprise and ghost Buster rigs.
@@RimstarOrg wimshurst USS Enterprise design .
Wimshurst ghost Buster rigs designs.
Wimshurst used in Welles time machine.
In reality they don't use.
Only in fantasy.
I wish my ball were as charged as those described here👃
I wish my ball didn't premature discharge.
This does not explain why it generates sparks when rotating only in one direction, nor the ozone smell, nor why it creates measurable radiation the longer you use it (try measuring with a dosimeter next to a collecter).
臭氧是空气被高压电离，至于使用后会产生辐射也是高压
The ozone is probably formed by oxygen molecules being exposed to high temperature/high voltage.
So you turned the pyramids into a wheel! Well done, imagine your hand or the wheel been earth spinning, and your negative is the iron core! Every 100ft u go up it’s about 100kv now can you see how the system worked that lit earth up! Free energy baby. 👍🏻
Difference in potential as you gain elevation is due to lightning discharges to the Earth, not any pseudoscience of energy in the pyramids or a charged core...
the fact that you explained all that is crazy. you are a miracle man. Crazy gifted. lol omg lol
Thanks! It took a long time before I came up with how to explain it well, but I really wanted to do another "work of art" like I did with my crystal radio explanation ruclips.net/video/0-PParSmwtE/видео.html.
One thing my father told me, is if someone is better than you, you learn from them. I'm subscribing :P you god damn savant!
Nice presentation. Let me understand the operation enough to ask questions.
Why the capacitors continues to take charge and not saturate? or will the charge in capacitor flood back into the next charge carrier?
great question
nice. that really helped me understand. thank you.
Is this better than a Van de Graaf for the DIY-er? I made a Van deGraaf from coke cans but never got large sparks...good job on video...
You can get large sparks from a Van de Graaff generator too, you just need to make it bigger. I made a small Wimshurst machine and it's even less powerful than my coke can Van de Graaff generator. So I wouldn't say either is better. However, since you've already made a Van de Graaff, maybe it would be fun to try a Wimshurst machine this time.
Brilliant explanation - much superior to others I have found on the internet. Ever since I first saw a Wimshurst machine at school, 50 odd years ago, I have been mystified by how it could possibly work. Now I know (I think). Thanks!
Ditto! 45 years ago there was one stored in the back of our Science/Physics classroom. I never knew the name or what it was for - thanks for teaching us!
Such a great explanation. Thank you very much!
The fact is micro amps or milliamps current occurs , but how I=V/R equation conform with that? Where is so big resistance ? More over in example with 200meter ionized wire again (not a storm condition) pico amps current flows from earth to the top . I am confused
The air in the spark gap has high resistance
I was going to comment + - Porn ... then I saw 9:14... Subscribed!
Definitely referring to spark plugs as malfunctioning capacitors from now on...
im here because of a band with the same name as the maschine but that was a wonderful lesson perfect midnight knowlege thank you!!
Can you remove the "third capacitor" the one that sparks and connect all other capacitors into a battery and turn the current here into any usable energy?
Theoretically, yes. The voltage will likely be too high for the battery charging. Also, Wimshurst machines have been known to switch voltages while running -- one collector may be positive and the other negative, and then something happens to the charges on the sectors and all of a sudden the polarities at the collectors reverse. But if you can lower the voltage at the output then some diodes would take care of that.
@@RimstarOrg i kinda want to connect Wimshurst machine into a stirling engine to produce even the slightest useable energy, i wonder if i can do it with that configuration
Theoretically it's doable. The Wimshurst machines crank does take quite a bit of torque so you'd need a powerful Stirling engine.
How has he done those animations?, they look great.
Thanks! I use Blender, free 3D modelling and animation software from blender.org
I understand how this works, but nobody seems to mention the voltage multiplication effect of the contra-rotating discs. At school we were taught that Q=CV. When two plates are opposite, they have a fixed charge; as they move apart, the charge remains the same, but the capacitance is reduced, causing the voltage to increase proportionately. Once the plates are at maximum distance, the voltage increase is sufficient to enable the charge to 'bleed-off' to the leyden jars via the corona between the plates and the collector points. Have I misunderstood something here or just missed a point?
Hmmm... Interesting. I was aware of the voltage increasing as capacitor plates are separated but hadn't considered any part it may play in a Wimshurst machine. That voltage is between the plates but I guess since the collectors are capacitively coupled through the collectors then the voltage on that side would be affected too.
3:41 why ALL negative charge goes to lower sector? For charge is better to be split between upper and lower sectors? Isn't it?
At 3:34, the negative charge in the sector shown at the top repels the negative charge to the lower sector. That's what's really doing the repelling. The amount that will be repelled depends on how negative charged that top sector is.
Brilliant! I never knew they where as complex as that - the ones I played with as a boy in London's Science Museum are all mahogany and brass with most of the workings hidden away.
So the one on your bike - could you put a xenon strobe tube across the spark gap and have a headlight that made it look like everything was static? (pun intended)
Thanks! You'd have to hide the disks in a casing too, otherwise the spinning disks would also give it away.
Fantastic explanation and illustration, thank you!
your a professional narrator. i will watch all of your videos. i wish i had money to send you. what is your education? who are you? do you have a resume? you just seem to have appeared. your what utube is all about. have you ever thought of having a workshop were you teach people. were are you located? your like the wizard of oz.
I've been teaching in various ways all my career, it's an addiction. After I did programming, for many years I traveled all around the world teaching QNX to engineers (blackberry.qnx.com/en), but I've also taught evening classes for a local school board, and so on. I've also made movies when I was a teenager, and I've always enjoyed making things, science, and electronics. So RUclips allows me to combine all those things. Thanks for watching my videos. I'm glad you enjoy them.
What if we connect a small light bulb in between the capacitor or inbetween the spark gap, will it light up?
A small LED might light up. I know I've seen people put small LEDs where the neutralizer bars are, so cut a neutralizer bar and insert and LED. That works.
I think the term "neutralizer" is confusing.
I agree. It neutralizes in the sense that it makes the charge at the two ends the same, neutralizing them with respect to each other but they still carry a charge, just the same charge. They're not neutralized though in the sense that they have a neutral charge. Confusing.
@@RimstarOrg "It neutralizes in the sense that it makes the charge at the two ends the same" I thought that too. I think a better name would be "Charge pre-collectors". The collectors would be the end-collectors.
The Testatika generator belongs to the group of electrostatically influenced machines, which have been developed since the 19th century, most notably the Wimhurst machine in 1880.
In Switzerland, Europe, late 20th century, 1990s, the Swiss corporation Methernitha is said to have developed a self-powered generator (powered by its own feedback energy) in the form of a circuit. electronic. The Testatika generator is a self-powered generator, with the initial starting voltage being generated in the manner of a Wimhurst machine.
Nice video sir...
Very easy to understand.. Thank you
nice video it helped me to understand the aparatus, thank you very much! but one thing is missing a bit. the charge at the opposite sectors must become continuosly higher because otherwise it would not accumulate in the leyden jars. the fact that at the beginning it have only ONE sector charged and it influences charge separation at TWO sectors on the other plate makes the over all electric field stronger. this two charged sectors then rotate further and influence even stronger charge separation on the other side sectors and so on. so the charge separation effect adds up every time the "new/higher " charge meets the opposite neutralizer, and therefore charge becomes alternately higher on the front side and back side and cycles clockwise and anticlockwise.
That's correct. The charge on the sectors builds but quite a bit. The limiting factor is the leakiness of the sectors. In the dark, they glow with corona at their sharp edges and with corona between them. You can also smell ozone. If you don't collect at least some of the charge at the collectors then it becomes hard to turn the crank due to the strong attraction between the opposite sectors which in turn is due to the amount of charge on them.
Thats impressive. I would Not think that you can feel the force on the crankshaft Wow
I must be slow. I don't understand how this generates a charge and why it keeps growing.
All I see in the description is a lot of capacitors and wires holding charges. If you put a charge on a capacitor and then start connecting it to other capacitors the charges move and distribute but they don't grow in magnatude. They just keep getting smaller as you spread the charge over more capacitors.
I can grasp how this acts as a charge "sorter" so random starting charges get sorted by the action of the neutralizer bars moving charges. But I don't get how those sorted charges can ever exceed the total starting charge.
So what is the mechanism that causes the the charge to grow larger in this device?
I understand the mechanical motion of the device is the source of the energy generating the charge but I don't grasp how this works.
And why are the collector's pointed air gaps? Why not use another wire and brush to collect the charge? And what keeps the charge in the liden jars from returning to the disk? I don't understand why there is a one-way flow at work there.
My friend is convinced that this device can be used as a source of free energy. "I can harness this, regulate it, and then store it so it can later be used to chrage my batteries!"
Im not sure how to explain how that is not exactly likely.
He feels he just has to start it and walk away. Then come back to full batteries.
That isnt true is it?@@CurtWelch
Why don't the collectors touch the plates? Could they?
I think the reason they don't touch the plates is to allow a higher voltage to build up on the Leyden jars and across the spark gap. If they touch the plates then the plates that they touch will become a part of the larger high voltage capacitor and would probably discharge to adjacent plates. At least that's my guess.
@@RimstarOrg If the charge jumps the gap from the influencing plate to the capacitor couldn't we assume the same in reverse (the capacitor can jump back to the influencing plate)? And wouldn't the capacitor, once having the greater charge, function in this manner?
So technically it should never obtain a greater charge (voltage wise) than the influencing plate can provide? If it did, wouldn't it push against the influencing plate?
It seems they could only ever truly be equally charged (again, voltage wise, I guess?).*
Though, the capacitor being double walled increases it's capacitance due to the attraction of the opposite 'capacitor plate.' Of course the 'influencing plate' is still a part of that circuit..so, if connected, the capacitor should still draw charges away.
Once full, the nearby influencing plates have the same charge so they shouldn't be affected any more than the one touching the circuit. It may arc to the previously used plate, I suppose; though it's capacitance is low so not much loss would occur and only at peak charge anyway.
In fact, since the capacitance is greater on the capacitor, it's likely 'capacitively' charging until voltage is equal; where they both (the capacitor and the influencer plates) would then, I believe, simply work together to ionize the air (hence the coronal discharge you mentioned that becomes visible).
*Interestingly, I think this is analogous to fluid dynamics, specifically hydraulics; where it is easy for a small syringe to inject a larger one while the reverse is more difficult. This would mean a smaller influencer plate could provide greater voltages and/or capacitance?
Does the small plate actually have the same maximum voltage capability as the capacitor only with less capacitance?
I was just watching your cd wimshurst machine video and it occurred to me that, if it doesn't touch, the plates probably don't fully discharge which means they carry on somewhat over/under charged, too. So causing it to touch should only maximize the transfer; where the wire itself would probably produce the coronal discharge (being pointy by comparison), once the capacitor is full.
Unless connecting them weakens the influence and the air is needed as a medium??
I don't know, but It sure is fun to think about! I definitely enjoy understanding too, though, so thanks for your guidance and help!
Edit: Lines of force must come into play too. I wonder if adding a point to the influencer (lile the collectors) would aid in the transfer and reduce ionization/coronal discharge of the air.
Maybe even nested conical shapes? The emitter, like a solid pointed cone and the collector covering it like a dunce cap?
The collectors on my two machines DO touch the sectors and both work fine. This question continues to baffle me.
Yeah, it's a tough question for me too. If I were to try to apply my answer to your case, where the collectors do touch the sectors, then I'd say that you're not getting much loss from sector to sector. The sectors I'd worry about losses at are the one which has just passed a collector and the one that the collector is touching. The one that just passed the collector would be neutral and so there'd be a big potential difference between that one and the one touching the collector. That could lead to corona between them and conduction through that corona.
Why not use flat magnets?
Use flat magnets for which part?
No hay explicacion logica sobre la distribución de cargas; ya que ambas botellas tienen las mismas oportunidades de captación de electrones.
¿ Y que serian esas cargas pintadas de rojo ( +) ? . Tal vez Protones ?. Disculpe si no lo entendi muy bien por el idioma, pues yo solo hablo Español. Pero me di cuenta de su explicación. Pienso que el estudio de la electrostatica aun esta en pañales. Saludos.
Tu espanol es muy bien. Deseo que mi espanol era tan bien como las suyos.
Estoy de acuerdo. Pero por lo que yo entendí ambas botellas no se cargan igual, y por ello entre ellas se crea una diferencia de potencial que se iguala o equilibra cuando salta la chispa en el explosor.
Thank you for your great video!
Amazing explanation
It's like the first electromagnet disk player...
The design is similar to USS Enterprise...
The power too.
Took a dream catcher ..
Replaced wood with brass rings.
Replaced string with coated copper wire .
