House of the Rising Sun?
That is by far and away the nerdiest pun I have ever seen.Love it!
It's plasma-tastic! The startup looks brilliant.
The other way around. And as an interesting note, this fusor was fed with AC. In this configuration it self rectifies.
The grid here was stainless steel tig wire.
Thanks for the comment!
@KittyRokher Thanks for the question. The pump is not shown, but at the beginning of the vid, you can see the red vacuum line connected to the left of the fusor. The pump was a standard Ritchie Yellowjacket HVAC style portable unit.
Its been 2+ years since I ran this thing, so if i recall correctly, it was a 9kv 30ma NST. No deuterium in this model, it would be a total waste as this was not designed to fuse. Only testing the vacuum properties of various epoxies.
Man, you are an artist ! When it start, i have think a new star is born in your borosilicate tube. Congratulation! It's a very very beautiful.
@yakkit I think around 200 microns a fuzzy poissor with multiple bugle jets begins to form. In the video, I fluctuated the vacuum from atmosphere to about 70 microns. Below that, bugle jets disappear and electron beams form. The poissor also gets very small and well defined.
@DavidBurnward He has made plasma. No fusion occured in this video. Air was used as the gas, not deuterium.
@legomaniac150 Believe it or not, the small fusor self-rectifies. I havent tried it with a larger one, but this tends to operate fine on its own. Otherwise, I have a bunch of salvaged HV MW diodes that work just fine.
That startup is so satisfying you have no idea
Hey! I'm a huge fan. I saw this video years ago, probably when I was in middle school and now that I'm in college I'm actually in the process of designing and building a fusor myself! I was hoping you could answer a couple questions that could help me out. If you have time to answer even just a couple I'd be super appreciative!
1. What kind of vacuum port did you use? Is it the same type you'd recommend if I'm trying to actually get deuterium in and out of the chamber?
2. Did you have problems with air pressure rising as gas leaks in? Did that ruin your results? I work in a chemistry lab that uses strong vacuum so I have seen first hand that any time there's a vacuum there's ALWAYS gas leaking in.
3. How long were you able to run it at a time and what was the limiting factor? I assume something got too hot. What was it?
4. Do you know what kind of current you were getting? I am planning out a Cockroft Walton voltage multiplier at the moment and I'm trying to get the best compromise between voltage and current to achieve a satisfying result.
5. I didnt know until watching this video again today that you were still active and making fusors. I have only seen one of your more recent videos so far. What changes would you recommend making/what warnings would you give to someone following a similar design to what you show here? Any advice for a newbie would be appreciated.
Thanks so much! And thanks for the years of inspiration!
Love the plasma fusor and the music, I just love watching this video every so often
His entire neighborhood lights up as well.
Are you planning to record a tutorial for this and the circuit? I would love to build one!
Looks real cool...
It's a beautiful piece of science.
@solomonXR1 No. The brass caps are big enough to support ion recirculation. For neutron production, effeciency may be hampered a bit. However, neutrons were never made with this ultra-basic demo model. Probably couldnt anyway due to a wide variety of factors. As an interesting side note, the system (as pictured) was self rectifying. In other words, it was powered by pure 60 cycle AC.
I'm reading through these comments and it amazes me how much misinformation there is about fusion in general. Check out fusor.net for some great resources to learn how this works and even how to make your own!
I've been saying the same thing on this thread for years and years. fusor.net is the #1 RESOURCE.
Looking to make one with just about the same measurements. For the heavy tubing, could you recommend me a website to get these from? Also you did a great job with this fusor!
Epic. Definitely the coolest thing I've ever seen on UA-cam, other than when I first encountered Minecraft Alpha in '09.
The cylinder was made from heavy walled borosilicate glass. I m confident that it can handle a fairly deep vacuum under normal conditions. However, the fusor heats up really quickly. If allowed to run under full power for any length of time, I am just as confident of its failure. Regarding the epoxy adhesive, it works great as long as it has no direct contact with electron / particle beams, or plasma.
I had no idea there was video as well! I thought there were just pictures... brilliant!
@SantisNight
It also makes a very good neutron source, which has multiple applications in commercial industry.
Believe it or not, this fusor was self rectifying. Not too different from a 6BK4 shunt regulator tube. I powered it with an un-rectified NST.
Its been 2 years since I last worked on that but I think it operated around 20-30 microns.
I love it, if you guys want to make one, go to junk yard and pull out a h.I.d ballast from a newer car headlight. This gives you up to 20kv start and 2 to 3 k nominal. Very easy transformer.
Very cool! That's probably the coolest small thing I have ever seen. Is it reusable? I was thinking of possibly making one...
This is amazing. Truely beautiful. I wish i could construct something like this, if not exactly like this.
@bigglesworth5283 As clearly stated in the description;
"Just a proof of concept idea regarding the fesibility of hardware store epoxy in a high vacuum environment."
At NO TIME was this ever made to be more than that.
Is an outer grid needed? I've been using fusor net and have only seen Fusors with outer grids but I don't see yours. Great video and thanks for the upload!
@iordacho As pictured, air. Tried Argon before retiring the system.
not to sound disaproving (because it looks badass) but what would something like this be used for?
The comment section of YT is not formatted for detailed instructions on a fusor build. However, fusor dot net, is an amazing resource for this type of project.
D2O is hard to obtain but not impossible.
@chicagobanana11 Very good question. I have been using the same set of 4 NST for the past 11 years. They are all 30ma and range between 7500 and 15000kv. I have used and abused them for everything from Tesla coils and Fusors to capacitative discharge quarter shrinkers (can crushers) and halloween decorations. Still going strong! Had one hiccup with the 15kv unit, but nothing that a quick oven bake didnt fix...and that was about 7 years ago!
Oh, and when needed I used a variac.
@sixpackwill1 its not, whats happening is the grids are causing ions in a partial vacuum to become grouped into a very small area and collide with some force. Very few fusions are happening, if any
0:48 that is one of the most amazing things I have ever seen on UA-cam.
A tuly impressive demonstration of IEC for the time and materials put in.
I do have a rem ball (bonner sphere type) neutron counter. However, I would never attempt at generating neutrons with a device like this. I only put this together to test different types of epoxies.
Someday soon I will make a quick video on the neutron counter. Its been on the "list" for awhile now.
@TheChemlife The pictured device does not release neutron radiation.
wow thats very cool is there a place to figure out how to make one? and also i heard on other videos that these things release radiation...thats only for really high power ones right?
I'm assuming the results were successful as far as the epoxy holding up under vacuum were concerned?
@magicstix0r If you are referring to power generation, no one will (or should) disagree with that. For neutron production via thermonuclear fusion, they are quite feasible and real.
Is there anything you can point me twords to contrast something like yours? Everything Ive seen is complex but yours is elegant simple.
+clagwell Is this leaking? Why does the plasma seem to be exiting the inner sphere? I imagine this shouldn't happen in a full fusor?
As soon as it gains energy it overcomes confinement.
That thing looks so damn majestic.
Excelente trabajo !!!
looks great man maybe you can help me with a problem everytime i try to make a fusor it never glows it just arcs what am i doing wrong ty
The amperage would be too low. A couple of old MOT's in series have been known to work well.
A member of fusor.net has been conducting that experiment for the past month or so. Pics included.
But not much, just two independent poissers.
Some basic questions please :). 1. Is it dangerous , can it break explode etc . ? ....2 what voltage is injected ? What sort of temperatures are created within the core ?
Dont recall exactly since it was 4 years ago. However, it was powered from a ballasted 7500 volt NST. So perhaps around 5kv.
Also, does this emit any dangerous radiation?
this would be so cool as a tabletop device
bit worried about the prolonged exposure to the neutron radiation it produces though
That song
@spinafire Yes. I am sure I could pull it out of the display and make it work. The epoxy is just as strong as it was a couple of years ago.
Hello,
I have a question about your vaccum Pump? What kind of Vaccum pump do you use ? And what do you think how hard should the Vaccum be ?
@clagwell Thank you very much, I watched more of your videos and they are awesome.
At what pressure is it operating at? There doesn't seem to be any valve for the vacuum pump
Specific to 333's remark, apples and oranges. Just beause it looks similar, doesnt mean it is. So to answer you question, yes, it is plasma and ball-like in apparence. But in almost no way is it like a novelty shop plasma ball.
On a larger scale, this process is capable of small scale nuclear fusion. The process used for the toy version is totally different and only capable of making artistic plasma effects.
Your video has inspired me. I did a bit of research on this. Something I'm not seeing in your fusor is the "outer grid". Where is it? Is it even there? Is it not needed because you aren't going for the intensity of neutron radiation? Are you using the metal ends as your outer grid? or what? I want to build just for the glow (like yours) and if I don't truly need an "outer grid" that drastically simplifies the design I had in mind. Thank You
The outer grid is the metal plates on the top and bottom of the chamber (however only the surface of the metal plates on the inside of the vacuum will be used). This design doesn't produce neutrons from what I can observe, only a plasma discharge made from ionizing ordinary air molecules and colliding them at the cathode. Neutrons would be produced in an actual fusion reactor, but since shielding from x-rays is necessary, I don't think that this fusor actually "fuses" anything.
***** 100% correct.
As stated years ago in the above video description:
A fusor constructed with 5 minute epoxy. Nothing special here, just a proof of concept idea regarding the feasibility of hardware store epoxy in a high vacuum environment.
This is a demo fusor. No fusion. No hydrogen. Just air.
clagwell I'm actually making my own fusor and the process of trying to obtain a low vacuum is proving to be a bit difficult (i am just using viton o-rings as the sealant). However, now that I see that epoxy works very well, I might consider doing what you did. And just out of curiosity, what was the vacuum that you were pulling to achieve that plasma discharge?
What happens when you bring 2 fusors close together, preferably in the same vacuum chamber ?
do you think that effect would work permanently, in a sealed glass tube? i'm tempted to try that!
It should work
@@ClagwellsGarage why is the fusion happening inside the grid? I would have thought that it should be around the grid and therefore between the anode and cathode! But this doesn't make sense to me!
So technically if the grid was replaced by a plate, do you think that the plasma would form behind the plate? I'm sure that you have seen what the sapphire project has been doing, they are using a solid sphere but they have also tried a hollow sphere but your experiment clearly shows that if there's no surface, the gas will condense against itself!
Unless I'm mistaken, is that grid the anode or is there an anode inside the grid?
It's an excellent experiment! This video predates the sapphire project but they have taken it further and at a larger scale!
I think that they are looking at the energy going in vs the energy going out and I believe that they are thinking about using it to boil water to drive a turbine for electricity production! It's definitely clean and doesn't leave behind anything toxic and it can be shut down instantly! The future is bright!
How high vacuum are you using & how did you reach it?
Am attempting to construct a fusor and need a vacuum pump. would a modified fridge compressor work?
@spinafire Actually, using tritium is EXTREMELY illegal. In order to get fusion, people use deuterium. But if your not aiming for the goal of fusion, you can use almost any inert gas to make a plasms light show like in this video.
Interesting. Have you used a neutron detector? Is it above background?
In plain terms, I'm curious about the safety.
@ChmodLabs There was no instrumentation on this run. For visual effect, I fluctuated the vacuum from atmosphere to between 40-60 microns at its deepest. Just a guess based upon the bugle jets and the lack of a electron beam which is indicitave of a much deeper vacuum.
Rising sun indeed. It seems that this is operating as little more than a gas discharge tube. If some sort of refractory adhesive (like what's used to seal some types of halogen tubes) was used, is this safe enough to run for extended periods of time? It looks like there might be an appreciable amount of UV in there. Any danger of x-ray?
is there a speicial gas in the chamber or is there just a high vacuum
wounderful! did you use a glass cylinder or plexiglas cylinder?. if it wasn´t plexiglas do you know if it would work in high vacuum?
Few things. 1.) Awesome job on the fusor! I love loctite's 5 minute epoxy and clearly it was a great choice for this project. 2.) This is an awesome House of the Rising Sun version. Where can I find it? 3.) While this fusor has a relatively low input voltage and may not produce x-ray radiation, is it possibly still producing UV radiation?
Operating voltage is too low, something like 7kv. In other videos I ramp it up to about 20kv and show how xrays are present. If you want to construct a real neutron producing fusor, the voltage will have to be high and you will most definitely have xrays.
I have one of my own on my channel but I'm trying your exact design (more or less) as a comparison. In yours are both end plates grounded or just the one on the left? Also what is your approximate current?
Also what do you think the effect of doing a side feedthrough would be?
VERY neat!! I've seen several "Farnsworth Fusors" online. Now, I have a new project, to add to mt Tesla Coil & Jacobs' Ladder for my haloween party. :)
Simply put, yes. But dont expect self rectification with a chamber much bigger than pictured.
I'm a noob to this area, please can you make some kind of guide to make one of these? That would be awesome! And where did you get the vacuum system? How much did that cost?
@clagwell Is the centre grid negetivley charged? If so how did you achive it with a NST?
What is the power supply to the confinement coils? DC, AC, volts and amps please.
@clagwell So you don't need special gas? I heard you can use tritium, but I haven't really researched fusors that much...Do you know a place where I can research plans?
Hey, out of what and how did you make the filament and grid and what are you using for the vacuum?
You rock man ! We can see a kind of magnetic field similar to that of the earth.
i want to live inside one of those.
Hello,
Was wondering what kind of pressure you had the chamber at, and if anybody knew a good place to get some borosilicate tubing.
Cheers,
Tom
Is it hot to touch on the glass?
I'm assuming you need to wear protective clothing around these things?
this thing is beautiful
I havent seen anyone go below 30ma. However that may be due to the fact that most people use NST's. NST's usually have a 30ma rating. I would bet 10-20ma would work too for standard glow discharge.
sorry for all the questions but i have a big one does this have any harmfull radiation or the sort and if yes do i just take a regular jar and put a vaccum and run 9000 volts though it
Just an air vacuum. No plans on introducing any kind of gas to this device.
where did you get the NST and how did you actually wire it up? thanks
"No hydrogen. Just air." 1st vacuum is supposed to get that out second air is 2 oxygen so your fusing 2 oxygen molecules technically just wanted to let you know but despite that it looks awesome
Sorry if this was already asked, but could you possibly make a tutorial video for this?
Well more specifically a small one i know that MAKE made a tutorial but i dont have access to all those kinds of tools, if you dont that fine just figured id ask.
i'm thinking about building one of my own powered from a flyback transformer, do you have any advice for me? please help
Would a 30 mm/hg vacuum pump be good enough for this?
@spinafire For what I have shown in this video, no special gasses are required. Go to fusor dot net and use the search function. The archives go back more than 10 years and is rich with excellent data. Pretty much every question that could be asked has been and answered quite well.
@lezsmokehaze420 Yes, it is plasma. For a full description of whats happening, I suggest you go to fusor.net. Its about the most informative site regarding the fusor.
Thanks for the reply! Will steel sides work? And do you know what type of wire he used for the inner grid?
hi, its a ETW type fusor with -ve charged end plates right? how many torr is there in the fusor?
A stainless steel containment vessel, preferably with conflat flange type vacuum connections.
A variable (and metered) DC power supply capable of 30kv at 50ma.
A well metered vacuum system consisting of a roughing pump and a diffusion pump. Should be capable of drawing a vacuum down to 5 microns.
A gas handling system to slowly meter in the deuterium.
what can i use for vachum? is a car tire 12 compresor good enough? or a refrigerator compresor? (i ask of this 2 because i have both riged as compresor or vachum pump)
What is the grid made out of? ( and where do you buy 2"borosilicate tubing?!)
Evil Morty The grid is stainless steel Tig rod. The tubing can be purchased at most glass supply places. Sundance Art Glass in Ca usually has good stock.
So, you made a plasma ball... They sell these at novelty shops bro =P
