For all those interested in power generation, please read this pinned comment. The Farnsworth fusor is NOT a power reactor. The actual fusion energy being generated here is MANY orders of magnitude lower than the energy going in. This reactor is only used to demonstrate that nuclear fusion can be achieved on a small scale and as a decent neutron source. So please don’t ask how much power is being generated here or if it can be used to power your home.

It real fusion reactor, RESPECT AUTHOR!!! I'm Very bad know english language, but is is Very cool, thanks you author! I'm from Ukraine. P.S I like video, good luck :)
This is so nostalgic for me as I worked in 1980-1986 with TOF mass spectrometers I built. The pumps and instumentation were very similar. Can you make the DT reaction be more effective in the Fusor if you force the ions to move fast back and forth? Instead of using a DC HV, you could use an AC HV in the MHz range to keep the ions inside the reaction area? The ions would go again and again to the center increasing the reaction efficiency a lot ro overcome the Coulomb scattering. Just an idea. Good work people.
2:57 Ah, yes. State-of-the-art Harbor Freight monitoring equipment. Really the only choice when it comes to fusion reactors. Seriously though, nice work. It's always cool to see the complex devices that can be built in a garage using (relatively) obtainable parts. I'm surprised this video doesn't have more views. It looks like something that would be on Applied Science's channel. Ben would be impressed for sure!
My old boss bought one of those and I had to show him how shit they are. Rated for 300V It exploded in my hands on 120V! (Yes I was using the voltage terminal)
That dosimeter is _really_ cool, it's so simple yet ingenious. I've been playing with HV again lately after a decade hiatus (got shocked, almost died, but now the gun shy has worn off🤣) and in my quest to make a 1.6KJ capacitor bank charger I've made a rectified variac-fed MOT (with a couple different switchable current and voltage options using a series of different wattage and voltage light bulbs in series with the primary, with a switch on each one) that puts out up to 3000V DC, and now it has opened up a slew of opportunities in magnetron sputtering, wood burning, and now fusors. I definitely need to build one of these albeit a lot simpler than this one, that chamber is just way too nice for my taste (budget😔😅). I have a cheapo $100 vacuum pump but I need something a little stronger for one of these too though, it doesn't make anywhere near enough vacuum from what I hear. Anyone got a spare diffusion pump?😉

Thank you! I am glad to hear that you got a discharge tube working. Did you use a refrigerator pump for the vacuum or did you use a dedicated vacuum pump?
Science Marshal I used a 2 stage vacuum pump I had from a demo fusor and a 15kv 60ma NST that I had from my SG Tesla coil. The bottle produced a brilliant glow discharge, with striations. I just uploaded the video if you’re curious. Thanks for the inspiration and educational videos.
I’ll go check that out now! I’m glad that you enjoyed the project and that my video was put to good use! I got my inspiration from other people’s videos and posts online, so I’m happy I was able to pass it on.
Too bad I didn't see this video earlier, it would have saved me time! I'll look for the dosimeter. I used the same setup of fuel cell and syringe as you did, however I didn't find it convenient to store, so I preferred to fill a small bottle by having deuterium remove water, and I store it top-down with some water at the bottom. I then open it under water and pick a little bit of deuterium with the syringe, then I can close the bottle. The water at the bottom is enough to make it completely sealed. I'll look deeper into your voltmeter schematics, that could help me as well. I'm using small power with a tiny central sphere (~8mm) initially due to limited room, and it seems to allow me to run at low enough current. Good job!
So this is an actual reactor since it gives off nuclear radiation. Cool ! For me in this project its not about the output efficency or anythink but rather the fact that you can just DIY something like this.
Hi, Clean job. In my experience, the GM counter gets saturated by high voltage plasma before anything else, but the hot pixels on camera are definitely high energy particles, although I would not jump into conclusion about x-ray "only".

Thank you! I placed my xray/gamma dosimeter in front of the window and I measured a dose of 10 mrem/hour while operating around 25 kV, so there is definitely a lot of X-ray radiation coming out of the window.

@@Muonium1 While I agree with the sentiment of your second post entirely, I still won't recant my original post. It was nothing more than the display of his multi-plate rotary fusor(and of course, the blind and ignorant zeal of government jackboots) that garnered the knock on his door.
John Keely, of his 1800's workshop in Philadelphia, had tech notes published, and a portion of his frequencies section would be beneficial for controlling Cold Fusion testing of deuterium. "The Snell Manuscript"- which is summary of 3 Keely's lab note books. One amazing test was frequencies applied for condensation of ambient air in sealed brass globe with various levels of vacuum formed on open bath mercury manometer vacuum gauge, without cooling, suction pump, or chemical ablation. He said he had control of the forces of nature. Tesla didn't like him because Keely got more of investors' money than he did.
Hi! There is one point i couldnt find out about.. how hot does the fusor get? Esp. The inner surface of the vacuum chamber. A fusionreactor blanket is covered with wolfram.. for example
Really one of the most informative videos on the fusor construction! I've started to build a demo fusor, with a goal to upgrade it once to a real one. Could you pls show or give a link how to make a proper flyback transformer? Anyways, thanks for a really good explanation)
I’m glad to see how everything come together. Now I want to try to build one myself. I have a couple of questions if you wouldn’t mind answering them. First Are there any rotary vane vacuum pumps that can get down to a low enough pressure, if not then would a turbo molecular pump work well. Second where did you buy your bubble dosimeter, I can’t seem to find them anywhere.
I would recommend that you head over to the fusor forum at fusor.net/board/. You should spend many hours reading through the FAQ threads. Your questions have been answered there. My mistake early on was not spending enough time reading the forum before beginning to purchase components. There is a lot of knowledge, useful tips, and trial and error that have been documented there already. So it's best to learn from other people's success and mistakes! As far as the bubble dosimeters go, they are only sold by BTI Bubble Technology in Canada. The model I got is the BD-PND. You will have to contact them through email to make an order. Also the bubble dosimeter should be the last thing you purchase when you are completely ready for fusion as they have a limited shelf life.

Going to be honest, I thought you made and actual Fusion Generator (as in for general power production) and NOT a Fusion Reactor, used to produce special matter(s).
I missed the part where you talked about the energy output, but could this potentially be an energy solution? On a micro level? Small-scale units powering homes?
Most forms of energy recovery rely on heat generation, but this requires moving parts, pressure differentials, refrigerants and heat pumps, and imperfect thermodynamic isolation. Since the neutrons break apart after a little while into protons and electrons you may be able to envision an electrochemical mechanism like a fuel cell, but with added energy recovery for hot electrons and protons via charge steering (proton positive, takes different path than electron.). Fast neutrons are very tricky to capture safely, and they do a lot of damage to any materials they hit, and can leave behind lasting radiation from transmutation or decay initiation.
The estimate is something like 1 watt produced to 1,000,000,000 watts used. You are looking for the magical man made break-even reactor to which no one has be capable of producing especially from a DIY reactor. Plus as the other guy pointed out the fast neutrons are very difficult to safely capture. There are currently no such thing as a break-even reactor created by man as no man made reactor has been capable of it. God's reactor, the sun, is a break-even reactor and that is the closest you can come to seeing one in action. That is why the sun is so goddamn amazing.
very impressed sir. So I'm a College student and had a couple of doubts I hope you would oblige to answer : 1) What are the measures you took to contain the radiation, or was it negligible since the run was so small? 2) What was the output ratio that you were able to get? Is there anything you would have done better to increase that? I'm looking to do Fusion as my Final Year thesis and would love to hear some good news. Nice forum article!
I was impressed with what I put out given it was at the peak of Covid. My paper wasn’t exactly great as it was a review paper more than a research paper My design was on AutoCAD as I wasn’t able to procure the materials for actual construction, given the restrictions in the country I was in and the industry wide lock down made it hard for companies to provide with lab materials like the gas and specific pumps
Yes, the chamber does get hot after a fusion run! That is one of the downsides of using a smaller chamber like mine for fusion. A larger chamber doesn’t heat up so much.
@@ScienceMarshall Awesome. I was hoping I could be able to add some sort of peltier module or something, just so I can say it has a purpose lol. Do you remember what size your Turbo Pump was? I've found a few on eBay, and cheaper than come of the diffusion pumps oddly enough. Also I don't have to fill it with the ridiculously expensive diffusion pump oil.
Congratulations! Please add shielding behind the window sensor, and consider wrapping the 316 Stainless vessel with a neutron absorbing and blocking material like Boron, Cobalt, Titanium or Molybdenum (316 Stainless only has around 2% Moly, no Titanium), with something dense and non-radioactive like Pb-204,206,207,208. This is a great achievement, but there are 10, 20, and 80 year consequences for increasing your exposure to fast neutrons and 30keV Xrays. At that energy the attenuation through water puts them at around 3 centimeters depth. As the energy goes up, they begin to go through much more material before they are blocked, and as they go down, there is a higher chance they will hit something in your body that might give you cancer. P.S. What do you think about accelerator moderated fusion?
Congrats on your build. I didn't quite understand your gas feedthrough. Do you not use a mass flow meter or some sort of needle valve to have fine control over the pressure?
So question: I assume this cant be self sustaining. I have heard a story of Farnsworth getting it to sustain for almost a minute. If it can be self sustaining by using just the deuterium as fuel, can the titanium sphere be replaced with titanium pipes and inject water which will turn to steam to spin a turbine to produce electric?
I know this is a super late response but seeing as no one else said anything i thought I’d chime in. To answer your question no probably not, there would be too many other atoms in the way of the H-2 to cause consistant fusion. What you can do is use to fast neutrons produced by this setup to cause fission in a fuel such as thorium then use the heat from that to boil water and spin a turbine but at that point you basically have a fusion reactor powering a fission reactor which, while still cool, isn’t necessary since you can make a fission reactor without all the extra steps
hello, i am asking for the thickness of the stainless chamber needed for this prototype. I saw the website mentioned in the description, but some information is missed.
The chamber was a standard Conflat reducing cross. I’m not sure what the thickness was exactly, but it is the standard thickness for conflat flange tubing intended for vacuum.
If you have a side project and are still in the university, never ever show or acknowledge that you've used anything belonging to the university even their garbage. You will have a hard time to get a patent because most universities have you sign an agreement that your IP belongs to the university when you get admitted.
It's nice to see this project work out. You should try to create some microscopic amounts of tritium using lithium-6. But I suppose you'll find it hard to get lithium-6. You will find out why if you look at the uses of lithium-6
Superbly made video! Informative and clear. How's your PhD going? I made a demo fusor a few years ago. Now I'm circling back to make a neutron producing version, so your video is quite helpful in seeing other people's set ups.
Thank you! The PhD is going well. I’m kept busy between classes, research, and my one year old daughter! In the next year or two I’m hoping I’ll have more free time to work on personal projects and make more videos once I finish all my courses. Best of luck to you on your quest for neutrons!
Hey, I am a high school student willing to do a project on fusors and neutron scattering I was just wondering if I can get your email to ask a few questions regarding the experiment and other things, Thank you
what was the total input power used? a water pump? 3 volts x 1 amp to generate deuterium how much deuterium in oz? to generate how much energy in watt hours 30,000 volts x 5 mill-amps = 150 Watts output I read on the internet that fusion does not break even in energy in vs energy out. can it be used to store energy like a battery?
So lets say 30kV and 2,5 mA, that means the outcome effect of this reactor is around 75 W? I’m new to this, does this generate power, or just a reactor that makes heat
I'm a student learning a bit about this. Can anyone explain like what this would be able to power? Could it power a house? Or a car? Amazing video, thank you and sorry for my lack of knowledge.
Nice job. A reliable fusor powered with a electrolysis rig is not something many people do. How do you feel about it overall? Worthing doing over the traditional methods?
Thanks! I think that the electrolysis method was much better than using bottled deuterium. No pressure regulation needed and no worries about running out since I could get a lot of deuterium volume out of just a little heavy water volume. It’s also cheaper and much more accessible to the home experimentalist.
From what I’ve read, drying will give a substantial increase in the fusor’s neutron output. That would be one of the first upgrades I would make to the system!
Science Marshall, do you know if this is correct? Or am I still missing something/is something redundant? Vacuum chamber Power Supply (slayer exciter) Vacuum pump Geiger counter High voltage divider probe Thermocouple Neutron radiation detector Deuterium gas Large ballast resistor Airborne detector
Sounds like you’re on the right track. I’m not sure what the airborne detector means. Also don’t forget some sort of high vacuum measurement that will let you know if you have a deep vacuum and allow you to monitor how much deuterium you are adding. You say “vacuum pump” but unless you’ve got an amazing mechanical pump you will likely need the combination of a mechanical vacuum pump and a high vacuum pump like a diffusion or turbo molecular pump to get the initial chamber pressure low enough. I would recommend using something like the ZVS driver + high voltage multiplier I used to obtain the high voltage DC. You need >150 watts sustained for 10 minutes or more in order to do detectable fusion with a bubble dosimeter. A slayer exciter isn’t going to work well for that. Even my power supply was on the low end power-wise. The bulletproof option is to use an X-ray transformer but those are a little harder to get a hold of. If you are really serious about doing fusion, please go to the fusor forum in the description and read as much as you can on the FAQs there. They will do a much better job than me at teaching you to do fusion.
Hi, thank you for the informative video. Would you mind me ask a question here: if I'm planning to use a 15kv neon sign transformer instead of the flyback, is it OK to use the exact same voltage tripler design as yours? Is there any need to manipulate the capacitance of these capacitors? I suffers from poor electrical knowledge, really appreciate for your help.
The Farnsworth fusor is a notoriously inefficient fusion device. The actual fusion energy being released is less than a microwatt, and I’m running it on ~1000 watts with my vacuum system and power supply.

I was going to build one of these but I got really depressed reading about proton decay and never did
That is understandable.
Can you elaborate?
@@blackwidows570 yes
maaaaan I'm just learning about this & it's blowing my mind in to the universe.
@@blackwidows570 he is joking. the experimentally derived lower bound for the half life of protons and hence the universe is over 10^33 years.
Hello sir, can you make oxygen concentrator or liquid oxygen generator with household things..if you could ,it will help many people in emergency situation and save their lives...thank you.
Water electrolysis produces hydrogen and oxygen
yeah, any ambient air water condenser would get you water to electrolysis oxygen out of it
That's how you get government ants.
nah, still gotta make a video showing it doing neutron induced fission in a piece of U or something to attract those ants
@@Muonium1 I think Codydon Reeder would strongly disagree.
@@AtlasReburdened even Cody wasn't doing anything illegal. I still wish he would have told them to fuck off and continued with his experiments. It's a totally clear freedom of speech issue. Nothing whatsoever illegal in the US about converting uranium ore to the metal on a miniscule scale like he was. They just like intimidating people and they need to be put in their place.
@@Muonium1 While I agree with the sentiment of your second post entirely, I still won't recant my original post. It was nothing more than the display of his multi-plate rotary fusor(and of course, the blind and ignorant zeal of government jackboots) that garnered the knock on his door.
@@AtlasReburdened what is a multi plate fusor
Grat Video. Awesome setup and thoughtful presentation 👌.
What I wonder is who is behind the drywall?
Thanks for this video, I got stuck while working on mine, and this really helped! 😊
John Keely, of his 1800's workshop in Philadelphia, had tech notes published, and a portion of his frequencies section would be beneficial for controlling Cold Fusion testing of deuterium. "The Snell Manuscript"- which is summary of 3 Keely's lab note books. One amazing test was frequencies applied for condensation of ambient air in sealed brass globe with various levels of vacuum formed on open bath mercury manometer vacuum gauge, without cooling, suction pump, or chemical ablation. He said he had control of the forces of nature. Tesla didn't like him because Keely got more of investors' money than he did.
Great job! Congratulations on a very successful run.
Thank you!
Hi! There is one point i couldnt find out about.. how hot does the fusor get? Esp. The inner surface of the vacuum chamber. A fusionreactor blanket is covered with wolfram.. for example
Really one of the most informative videos on the fusor construction! I've started to build a demo fusor, with a goal to upgrade it once to a real one. Could you pls show or give a link how to make a proper flyback transformer? Anyways, thanks for a really good explanation)
Hello, Im building one as well, Im making the demo now
I’m glad to see how everything come together. Now I want to try to build one myself. I have a couple of questions if you wouldn’t mind answering them. First Are there any rotary vane vacuum pumps that can get down to a low enough pressure, if not then would a turbo molecular pump work well. Second where did you buy your bubble dosimeter, I can’t seem to find them anywhere.
I would recommend that you head over to the fusor forum at fusor.net/board/. You should spend many hours reading through the FAQ threads. Your questions have been answered there. My mistake early on was not spending enough time reading the forum before beginning to purchase components. There is a lot of knowledge, useful tips, and trial and error that have been documented there already. So it's best to learn from other people's success and mistakes! As far as the bubble dosimeters go, they are only sold by BTI Bubble Technology in Canada. The model I got is the BD-PND. You will have to contact them through email to make an order. Also the bubble dosimeter should be the last thing you purchase when you are completely ready for fusion as they have a limited shelf life.
Ok, thank you and keep up the awesome projects.
nice work! congratulations and welcome to the neutron club!
Thank you! I've enjoyed reading about your fusor work on the forum.
Neighbours on the other side of that wall opposite the x-ray view port: "Why is it when the TV reception drops out, I get this warm fuzzy feeling and I can see the bones in my hands?"
That's some impressive work. Great job
Just WOW, huge thumbs up. Stupid question - can electricity be generated in any way (even theoretical) with your reactor?
Dope neutron source brother :) Good job & cool video!
This is incredible. Thanks for sharing.
When news articles say kids 14 and under have done all of this work, I don't believe them. My first question would be how they got all of this stuff without their parents knowing - or did the parents "help"?
Amazing job and great presentation!
I have been working for pinewood in roblox since a while,it’s better be careful with the fusion and core,I wore a PET hazmat suit and went to the core,therefore it worked except during meltdown
VERY COOL! I am going to power my house with these
Going to be honest, I thought you made and actual Fusion Generator (as in for general power production) and NOT a Fusion Reactor, used to produce special matter(s).
Wow neat. What would happen if you placed your hand in front of the view port? Is that enough radiation to definitely or potentially cause cancer?
hooooly mooooly this is blowing my mind!!! & the proton decay
I missed the part where you talked about the energy output, but could this potentially be an energy solution? On a micro level? Small-scale units powering homes?
What a great achievement 🔥
The next question is how to transform the produced energy in electricity. The energy must be greater then the input energy. I wish you luck!
Most forms of energy recovery rely on heat generation, but this requires moving parts, pressure differentials, refrigerants and heat pumps, and imperfect thermodynamic isolation. Since the neutrons break apart after a little while into protons and electrons you may be able to envision an electrochemical mechanism like a fuel cell, but with added energy recovery for hot electrons and protons via charge steering (proton positive, takes different path than electron.). Fast neutrons are very tricky to capture safely, and they do a lot of damage to any materials they hit, and can leave behind lasting radiation from transmutation or decay initiation.
The estimate is something like 1 watt produced to 1,000,000,000 watts used. You are looking for the magical man made break-even reactor to which no one has be capable of producing especially from a DIY reactor. Plus as the other guy pointed out the fast neutrons are very difficult to safely capture.
There are currently no such thing as a break-even reactor created by man as no man made reactor has been capable of it.
God's reactor, the sun, is a break-even reactor and that is the closest you can come to seeing one in action. That is why the sun is so goddamn amazing.
Nice camera. If ever again... make a picture of something you always wanted to look thru.
congratulations! well done.
very impressed sir. So I'm a College student and had a couple of doubts I hope you would oblige to answer :
1) What are the measures you took to contain the radiation, or was it negligible since the run was so small?
2) What was the output ratio that you were able to get? Is there anything you would have done better to increase that?
I'm looking to do Fusion as my Final Year thesis and would love to hear some good news. Nice forum article!
How did your thesis go
How did your thesis go
I was impressed with what I put out given it was at the peak of Covid. My paper wasn’t exactly great as it was a review paper more than a research paper
My design was on AutoCAD as I wasn’t able to procure the materials for actual construction, given the restrictions in the country I was in and the industry wide lock down made it hard for companies to provide with lab materials like the gas and specific pumps
I changed my thesis to then a comparison between Tokamaks and Stellarators.
Se ve que es muy buen video! Pero lastima que no hablo inglés! Hace tiempo quise hacer deuterio al vacío con una lámpara metiendole hidrógeno
Such a cool project. I’m working on my own at the moment, and I’m wondering if the chamber gets hot to the touch.
Yes, the chamber does get hot after a fusion run! That is one of the downsides of using a smaller chamber like mine for fusion. A larger chamber doesn’t heat up so much.
@@ScienceMarshall Awesome. I was hoping I could be able to add some sort of peltier module or something, just so I can say it has a purpose lol. Do you remember what size your Turbo Pump was? I've found a few on eBay, and cheaper than come of the diffusion pumps oddly enough. Also I don't have to fill it with the ridiculously expensive diffusion pump oil.
Congratulations! Please add shielding behind the window sensor, and consider wrapping the 316 Stainless vessel with a neutron absorbing and blocking material like Boron, Cobalt, Titanium or Molybdenum (316 Stainless only has around 2% Moly, no Titanium), with something dense and non-radioactive like Pb-204,206,207,208.
This is a great achievement, but there are 10, 20, and 80 year consequences for increasing your exposure to fast neutrons and 30keV Xrays. At that energy the attenuation through water puts them at around 3 centimeters depth. As the energy goes up, they begin to go through much more material before they are blocked, and as they go down, there is a higher chance they will hit something in your body that might give you cancer.
P.S. What do you think about accelerator moderated fusion?
hello, i am trying to build a fusor reactor, but I do not know what is the thickness of 316 Stainless needed for this.
Can you use a turbo molecular pump instead of a diff pump?
Bet you 5 bucks he's on a watch list
Congrats on your build. I didn't quite understand your gas feedthrough. Do you not use a mass flow meter or some sort of needle valve to have fine control over the pressure?
5:00 rig up an x-ray sensor, too!
oh, you did! 6:00
So question: I assume this cant be self sustaining. I have heard a story of Farnsworth getting it to sustain for almost a minute. If it can be self sustaining by using just the deuterium as fuel, can the titanium sphere be replaced with titanium pipes and inject water which will turn to steam to spin a turbine to produce electric?
I know this is a super late response but seeing as no one else said anything i thought I’d chime in. To answer your question no probably not, there would be too many other atoms in the way of the H-2 to cause consistant fusion. What you can do is use to fast neutrons produced by this setup to cause fission in a fuel such as thorium then use the heat from that to boil water and spin a turbine but at that point you basically have a fusion reactor powering a fission reactor which, while still cool, isn’t necessary since you can make a fission reactor without all the extra steps
hello, i am asking for the thickness of the stainless chamber needed for this prototype. I saw the website mentioned in the description, but some information is missed.
The chamber was a standard Conflat reducing cross. I’m not sure what the thickness was exactly, but it is the standard thickness for conflat flange tubing intended for vacuum.
If you have a side project and are still in the university, never ever show or acknowledge that you've used anything belonging to the university even their garbage. You will have a hard time to get a patent because most universities have you sign an agreement that your IP belongs to the university when you get admitted.
now i can make my doomsday device thank you forhelping me with this
It's nice to see this project work out. You should try to create some microscopic amounts of tritium using lithium-6. But I suppose you'll find it hard to get lithium-6. You will find out why if you look at the uses of lithium-6
you do know the half life of lithium-6 is under a second, right?
@@notioncreangaThere is no half life for lithium 6. Did you mistake helium-6 with lithium-6 since helium-6's half life is under a second
@@dankmemes6254 Shit. Forgot that lithium-6 and lithium-7 are the only stable isotopes of lithium. My bad :)
If you distill the tritium out of the worn out car batteries ? Ron cheap recycling
When you “pour in” hydrogen fuel, pressure rises a little bit. What is the maximum pressure you achieved during fusion?
It actually work now i can generate my own energy for my houshold thx a lot
No you can't. Takes more energy to run the machine than what the machine can give you. You'll end up with a hell of an electrical bill.
Esta é uma importante tecnologia para tornar a humanidade uma espécie planetária.
But is possibile know the energy product by fusion? It is much more than the energy for a fusion reaction?
Superbly made video! Informative and clear. How's your PhD going?
I made a demo fusor a few years ago. Now I'm circling back to make a neutron producing version, so your video is quite helpful in seeing other people's set ups.
Thank you! The PhD is going well. I’m kept busy between classes, research, and my one year old daughter! In the next year or two I’m hoping I’ll have more free time to work on personal projects and make more videos once I finish all my courses. Best of luck to you on your quest for neutrons!
Cool x ray emitter
Fusion yes
Would you make experiments with Solar panels around it? And how far away should it be placed?
Or did you need an fluorescent filter ?
Hi, is there any heat beeing produced in the chamber? If yes what is the temperature?
Hey, I am a high school student willing to do a project on fusors and neutron scattering I was just wondering if I can get your email to ask a few questions regarding the experiment and other things, Thank you
you should really look into storing those fusion products to cash in on when the helium shortage finally hits
what was the total input power used?
a water pump?
3 volts x 1 amp to generate deuterium
how much deuterium in oz? to generate how much energy in watt hours
30,000 volts x 5 mill-amps = 150 Watts output
I read on the internet that fusion does not break even in energy in vs energy out.
can it be used to store energy like a battery?
So lets say 30kV and 2,5 mA, that means the outcome effect of this reactor is around 75 W? I’m new to this, does this generate power, or just a reactor that makes heat
What can you do to prevent gettong any sickness from radiation? Also good job on the reactor. I am planning on building one.
Use a neutron moderator to slow down neutrons and cover the reactor with metal plating
Don't stand in front of the beam. That's literally it.
Do not look into the operational end of the device.
Iodine... rodin coil if you don't want to affect the neighbors... but maybe first culculate the circumference of the moon. Useless but save.
is it possible to determine the neutron output from the fusor (neutons/sec). I am trying to compare the outputs from this Fusor and a D-D NG
You gotta try breeding thorium to uranium 233.
I'm a student learning a bit about this. Can anyone explain like what this would be able to power? Could it power a house? Or a car? Amazing video, thank you and sorry for my lack of knowledge.
How much power is being generated here, can it be use to power my entire home?
OMG. That's amazing 😮😮
Nice job. A reliable fusor powered with a electrolysis rig is not something many people do. How do you feel about it overall? Worthing doing over the traditional methods?
Thanks! I think that the electrolysis method was much better than using bottled deuterium. No pressure regulation needed and no worries about running out since I could get a lot of deuterium volume out of just a little heavy water volume. It’s also cheaper and much more accessible to the home experimentalist.
@@ScienceMarshall And what about drying? The FaQs gloss over that quite substantially.
From what I’ve read, drying will give a substantial increase in the fusor’s neutron output. That would be one of the first upgrades I would make to the system!
I need to know about how to make a desktop synchrotron (proton accelerator). Is for satellite project.
Science Marshall, do you know if this is correct? Or am I still missing something/is something redundant?
Vacuum chamber
Power Supply (slayer exciter)
Vacuum pump
Geiger counter
High voltage divider probe
Thermocouple
Neutron radiation detector
Deuterium gas
Large ballast resistor
Airborne detector
Sounds like you’re on the right track. I’m not sure what the airborne detector means. Also don’t forget some sort of high vacuum measurement that will let you know if you have a deep vacuum and allow you to monitor how much deuterium you are adding. You say “vacuum pump” but unless you’ve got an amazing mechanical pump you will likely need the combination of a mechanical vacuum pump and a high vacuum pump like a diffusion or turbo molecular pump to get the initial chamber pressure low enough. I would recommend using something like the ZVS driver + high voltage multiplier I used to obtain the high voltage DC. You need >150 watts sustained for 10 minutes or more in order to do detectable fusion with a bubble dosimeter. A slayer exciter isn’t going to work well for that. Even my power supply was on the low end power-wise. The bulletproof option is to use an X-ray transformer but those are a little harder to get a hold of. If you are really serious about doing fusion, please go to the fusor forum in the description and read as much as you can on the FAQs there. They will do a much better job than me at teaching you to do fusion.
great job !
Good job
That's cool thank you
awesome job! what other experiments or differences in power supply are you going to work on next?
What happens if you use this to hit boron atoms with the hydrogen ions? I think it's viable
Outstanding
is there any way to test it before using raw materials just in case?
Hi, thank you for the informative video. Would you mind me ask a question here: if I'm planning to use a 15kv neon sign transformer instead of the flyback, is it OK to use the exact same voltage tripler design as yours? Is there any need to manipulate the capacitance of these capacitors? I suffers from poor electrical knowledge, really appreciate for your help.
Power is power,it doesn't really matter
Could you make it able to generate usable power? And that is efficient, it outputs more than you input...
The Farnsworth fusor is a notoriously inefficient fusion device. The actual fusion energy being released is less than a microwatt, and I’m running it on ~1000 watts with my vacuum system and power supply.
didnt burning the deuterium just produce heavy water vapor in your air?
Great job! Where did you land cost wise?
Hi. How to generate energy for a gas with this equipment? Is it possible to generate energy with it?
Found a listing for deuterium on ebay from global rare gases just saying
