My Farnsworth-Hirsch-Meeks Fusor - A Homemade Demo Ionic Fusion Reactor 

I can't believe I just learned of the existence of these things today. I'm learning a lot and your video is the best one I've seen so far. Thank you for taking the time to explain it!

Good news everyone!

It’s such a nice glow the body of the spiral is glowing too

Excellent project well executed & simply explained & well built. i plan to take a shot at one of these myself for a display piece soon hence finding your video production. those 5 years where certainly worth it. This is one of the best home builds ive seen so far. Ide like to have a pop a a deuterium set up one day, but the the level of construction needed is nothing short of industrial to achieve that. I will start simple, i already have a lifetime of HV experience, so there is a good grounding (pun intended) Its good to see people still doing things like this in the UK, excellent lab build to.

This is definition of beauty. Very nice project.

The overall clean and compact design is impressive!

if you want a cheap vacuum booster, get a pipe that is 30 feet long with caps on both ends. Then put a ball valve on one side (bottom) and connect a vacuum line to the other end (top). connect the vacuum line from the pipe into a Tee in your current vacuum system. Fill the whole pipe with water and then stand it up and put a bucket around the valve so when the bucket is full the valve will be submerged. pump as much vacuum as you can with the pump and then open the valve on the bottom of the pipe to start draining the water out, the 30 ft of water will pull an almost perfect vacuum.

Great content. I'm nowhere near an engineer or a scientist but I'm actually really enjoying it. Well done. Instant subscribe.

Congrats. You made a Florescent lightbulb the hard way.

Great video mate. Best and most simple fusor I have seen so far. Very supprised that your channel hasn't got many many times more subs. Keep on going on!

Underrated channel

Hi, just a suggestion, why didn't you use a capacitor to filter the output of the HV transformer, without one the, the supply voltage to the anode in the vacuum chamber will be pulsating to the frequency (half) of the mains supply, you can salvage one from a microwave and it would stabilise the dc current to the anode. Great project!

Hi, just wanted to congratulate you on the project completion. I've done a similar one using a few different pumps. One note thou, there seems to be some restriction in the vacuum line, like a check valve or something. You can hear the pump stop gurgling way too fast and that is not how it should sound with such a chamber. I think you could get a much improved vacuum if the lines from the pump was free from restrictions and not too small dimensions. Hope you get to run that often and inspire others to get involved in the field, greetings from Sweden (:

Thanks for very educational video ! excellent keep up the fine work !so much better than conventional "institutional monopolies" !📚📊📈👍📗

1. For your safety, verify the absence of gamma rays with a Geiger Counter. 2. A Utah state grad student built the fusor based on Farnsworth's patent document. He used a stack of CDs in front of his Geiger counter tube to be able to detect neutrons. It worked. 3. To get the electrical connection into the chamber through the plastic, next time consider using a ceramic feed-through capacitor. The capacitance value is irrelevant since you will be mounting the feed-through capacitor flange into the chamber plastic base or wall. Screw the steel post into a block of plastic inside the chamber which is then glued to the chamber base inside. 4. If you can disconnect the transformer secondary high voltage from the ground or transformer case, then you can use a full-wave rectifier bridge to produce full-wave DC output (2KV.)

i love the wooden box its attached to, building one soon hopefully

Very nice project and well documented! Just a question on your vacuum chamber: is that standard glass or is it some kind of plastic like plexiglass (PMMA) or something similar?

Nice job and nice expression ❤️🙏

Hi, great fusor, I was wondering, since its not able to fuse deuterium because of the neutrons and the radioactivity, could you try helion-3 instead?

according to other fusor videos there should be glow at the central point of the spherical grid, where the fusion is happening. Maybe it needs to be more symmetrical?

If you lose your voltage every half wave it seems that the ions will scatter and won't build up over time the way they would if there was a constant DC voltage.

FULL BRIDGE RECTIFIER ! Does it even generate a single neutron?

Much respect bro, and thanks for the knowledge. So cool.

Good new everyone!

Hi! I am a IB student from the Netherlands. I myself am building a Fusor for a school project and my question is if you would be willing to be interviewed for my Personal Project. Possibly give me some tips on the electrical engineering etc, I hope to hear back from you! Thank you in advance and kind regards, Jayden Beesemer IB MYP 5

Cool reactor! Did you say what was being fused in it?

great stuff what you did there.

Nice WoodenToaster toaster.

Nice project! How can you be sure that you are actually getting a fusion reaction? Do you have a gas analyzer? Or a Geiger counter at least?

Tendría que poner dentro de una cámara neblina para ver las partículas radiactivas

hope you've managed to get a diffusion pump

Will it fuse Hydrogen-1in air to helium-2 which decays to deuterium+ some particles and radiation, is this correct to assume?

i don't understand why you're not shielding yourself from the reaction, aren't there neutrons and xrays being emitted?

I need to know about how to make a desktop synchrotron (proton accelerator). Is for satellite project.

is it possible to get the high voltage from lightning and convert the energy to electricity and save it in a battery ?

2kVac rectifies is probably at a low end of reactivity for deuterium-deuterium. Too bad there was no neutron counter to verify if there is any fusion or if that is just plasma.

If your located in or around Las Vegas, let me know. High vacuum is a hobby of mine and I own a turbo pump as well as an edwards rv8

Have you made any more progress on this project?

But would you make experiments with Solar panels around it? And how far away should it be placed?

That’s just a lil weird plasma but then again it’s a small demo as said in the video

Doesnt this ball shoot out pretty strong radioactive waves? Or is this obly if you fill the chamber with deutrium

Am I the only one that first thought it said "Demonic Fusion Reactor"?

Doesnt atomic fusion give off gamma radiation?

What is the wavelength in nm that is being emitted please

Nice work

Hai i ask for u whether u using Hidrogen gas in vakum Chamber??

The side of the vacuum pump says it is able to reach a 0.01 Pa vacuum. That would be enough for a fusor (I think), so the 0.01 Pa pledge is not true :( Did you measured what is the best vacuum it can achieve?

What is the center of the Fusor made of? Is it a metal wire? Or is it Tungsten wire.

Wow awesome video man

This is my dad's invention. If anyone has any interesting questions, I can ask him....

And what is the power requirement for the diffusion pump could I get away with a pump that pumps 5 l per minute and could i use hydrogen as my fusion fuel

Could the chamber walls be the ground if made from metal instead of a glass chamber with the grid inside?

Two quick questions if I could: 1) Although this is a demo fusor as you say, does it produce anything that can be detected on a geiger counter? 2) If you run two microwave transformers in series, shouldn't that multiply your voltage again for more effect? Thanks! :)

Me and the boys making the sun

What are your thoughts on the Safire Project? They claim that injecting a catalyst provided at least a 20-fold amplification. Could that ultimately produce more energy than it consumes if sufficiently scaled up?

curious what you'd see if you were looking at it in the xray and infra red spectrum

Where do you buy deuterium?

Next build an Ainsworth Holy Grail Fusor

what a haircut

What is the material on the center??

Make a Dyson Sphere around it !!

Is that a uni-ball signo pen? That is the ONLY pen I'm able to write with :D Big thumbs up :D

I thought for an official fusion reaction it reaches temperatures of around 27 million degrees Fahrenheit (15 million degrees Celsius). I think I don't understand science. :P And 2 Earths plus negative I thought would cancel out each other. I thought Negative was earth and Positive was the opposite. Its an Ionisation system I think and what some old clock radios and lights used before the days old good LED's. Yeah Science !

Great project. Can you tell me what kind of fusion reaction happens? In the system with deuterium it is basically the reaction happening in the sun. So deuterium combines to produce Helium (with maybe the step in between where Tritium is produced). In this process also Neutrons are created. What kind of fusion reaction happens with air? I'm really curious about that

Good news everybody

I have a much simpler method of sealing the vacuum chamber. is there a way we can chat?

How do all of those neutrons and x-rays feel on your face bud?

hey mate if your interested check out my fusion reactor prototype. keep in mind I used theoretical work done by lpp fusion when I engineered this prototype. it increases the particle interactions allowing way lower vacuum and power requirement's and produces a high energy fusion reaction and is relatively easy to manufacture and is scalable. there are four videos on my channel this was a no deuterium test run of the first half of the test core and 28 mercury's is the vacuum so there's a major boost in performance if I get a better pump, and materials read the descriptions for more info.

when you convert the current into DC using the diodes where do you wire the positive end to complete the circuit on the electrode?

Amazing project! But i have a question, in this case, just pumping out air and firing it, does it emits radiation? And if you put other gases, like hydrogen, will it?

what if you used a vandegraf generator for the voltage?

Doesn't that emit neutrons when operating?

Congratulations on creating a lightbulb exactly the same principal sorry for the criticism

That’s not fusion at all

Good news everyone: you can buy tritium on amazon in tubes

Excellent video. Approximately how much did this particular system cost in its entirety?

With ordinary hydrogen shines just as well. This is an ordinary gas discharge lamp. Light is emitted when recombination of positive ions with electrons. A positively charged electrode separates the electron from the nucleus and a positively charged ion is formed - the nucleus of hydrogen. The positively charged hydrogen nucleus is accelerated by the electric field and flies towards the negatively charged grid. Electrons are produced on the grid, which recombine with hydrogen nuclei and emit light. If deuterium is used, then perhaps a small part of the hydrogen nuclei, accelerated by an electric field, collides in the center and forms helium-4. That is, nuclear fusion is purely kinetic. And it depends on the probability of getting into the effective cross section of the nucleus. To really start a thermonuclear reaction, you must first create a highly ionized deuterium plasma. Then, it is necessary to place this positively charged plasma in a very strongly positively charged sphere. So much charged that the repulsive force from the walls of the sphere was more repulsive forces in an array of nuclei. In this case, the nuclei will be concentrated and squeezed in the center of the sphere.

What's the fusion energy gain factor?

Is it truely a fusion reactor though? Just appears to be a plasma generator. Robert Pirlot said its an expensive light bulb

try boil some water with that. its actually just a ordinary neon lamp. they just call it fusion this or that.

A question: How come the plasma gets brighter and seems to have more of it around the electrodes the deeper the vacuum becomes? If the plasma is dependent on the matter and it's state then why as you remove more matter from the space does the plasma become thicker? Case in point: Start with no vacuum and set the voltage to a plasma inducing state then turn on the pump. As the vacuum draws more matter out of the space the plasma will develop and become thicker. WHY? If plasma was the state of matter then the whole space would become plasmatic and reduce as the matter is drawn from that space. That is simply not the case. WHY? Ever heard of cold plasma or dark mode plasma? what is the difference between the two modes of plasma cold or dark and hot or radiant plasma?

How did you get your H-2. Ie deuterium

wow you made a plasma globe big deal

Does it produce neutrons?

3:43 to skip the preamble bs

Now pruve that the video is not fake

Use safety glasses next time

Yeah

That’s not how philo farnsworth Fusor operates. Why do people keep making typical circuits and say it didn’t work? If you learn anything from philo farnsworth work and his multipactor tube you would see it is not wired simply with opposing high voltages. The devices use high voltages of the same polarity with a neutral floating grid.

yeah i think you just made a plasma ball that you could buy at a novelty store lol, still cool though i'll give ya that.

I'm currently working on a mini nuclear fusor for my physics lab of my school. Anyone who intends to create one want to collaborate with me? ☢️☢️

goggles man

2000В no .

Ok, base on comment and above video, that you can't vacuum all air and you say it is impossible? Why is that? Or you can vacuum all air, but part of air that is electrons is being vacuumed, so leftover is stronger particles that are nucleons. So, it interacts as there is nothing except each other, but of course, I can be wrong since nucleons is stronger that means the vacuum is not high or you say impossible that it pulls the nucleons, the stronger particles than electrons. So, perhaps you can't vacuum because it is not full as whole vacuum because of the rate of motion, per degree in Geometric shape that is the location of vacuum is on one side and below the side where the bottom is that is the air that travel to exit hole, which the diameter of the vacuum is smaller than bottom round part where you sealed it up, so the rate of degree motion. To make it clear to understand what I am typing that is the diameter is 180 degree, so above is a line of parallel 180 that is vertical to horizontal, so the wider part to narrow part is a divide which it is a fraction so you divide the remaining diameter into two sides of center diameter where the exit is, so for parallel diameter to side diameter to equal as 2 or more, so it needs more power as to travel to direction from far side to center side since the degree motion is in addition to horizontal motion, so can't suck all because it sucks with it. But if it is long horizontal that is a smaller size diameter that match bottom size, so it does not suck but takes a long time to suck it. So, ya can't suck all because it is a limit diameter of sucking to non-sucking diameter on the side, or no matter if it is parallel on the bottom, you can't take all air? I am sure ya can or it would be the particles itself exceed the vacuum power as the vacuum space in comparison to the diameter of particles, so the ratio vacuum is higher in power in holding the particles so the vacuum is not strong enough. Or it is about the energy of the atom itself that causes the motion in the higher level, the more the vacuum power increase so atom has freer of non-interact of other atoms so the energy of solo atom is higher so take more energy to remove it. But I doubt it. Another thing so the plasma comes from volt or the volt is necessary to start the process and which it interacts atom of air which there is no atom to atom, but directly atom to the metal itself, so it means high mean free path or clear path. So, it is about directly impacted, not indirectly impact which another atom that is secondary was getting bummed from the first atom, which the secondary impact to metal will not cause light? With high mean free path, there is only two interact from air itself to metal, so it is same as solid itself as there is no interact of solid, so the higher speed so it is about higher speed so the air in a balloon to above to ground, the balloon expands as the air inside travel fast as the mean free path is high base on the outside so the weaker pressure is expanding as there is no additional pressure from outside so you remove the outside, so the inside get stronger so it creates higher impact. So, it is about the impact that causes light. So, the volt is for what?? You have pressure which is negative pressure so you remove the air, so the speed of motion will cause the speed of the range of the gap of space is being filled at one time. What is volt for? LIke you vacuum the air that is fast so the steel drum will collapse because the diameter of a gap of space per ms is being vacuumed so it needs to fill up in milliseconds. So, when you have higher pressure to suck up, the energy forward to impact needs to be high so it impacts the center to create light. So. It is about balance of everything to make work. You can create two vacuum for external side and for the internal side, so using the right math so the speed of sucking outward to speed of sucking inward so the inward impact causes bigger light. That would be a good experiment to understand the balance to result of power.

Fusor (that isn't really) = Fluorescent bulb.

This is a plasma...... try to add some hydrogen to it. Then you will get F.Reactor

Seems that you made your own fusion reactor………… I was looking forward for magnificent glow but hey………… This is better than nothing I suppose

Hidrogеn and vacuum weak

Good job! But what you do is quite dangerous, you get bombed by x-rays every time you switch the Fusor on. And the amount is indeed not low without any shielding.

Noguchi of early 1940s Hamgyong did muon catalyzed better,
