How to make a demo fusion reactor(no fusion)

Pyrotechnical Science - 2019-08-20

This is just a demo reactor, no fusion is achieved (AKA a big gas discharge tube) just wanted to add this since a lot of people seem to be getting confused(:

hey guys this has been a long going project for me and I haven’t uploaded in a while so here ya go! And my apologies in advance for saying “ummm” every 5 seconds, didn’t realize until I made it(: also go check out fusor.net for more information than I explain. And as always enjoy!

Now I can make a hydrogen bomb

Jason Kloss - 2019-08-20

WOW THANK!! Now I can become Ironman and laser blast Syria and ummmm

Renite HD - 2020-09-27

DONT BLAST SYRIA

MinecraftMario Boy - 2020-12-21

Thank you for doing america a great service.

Pedro Trujillo - 2019-11-01

Harrison it’s Pedro I see you back on that YT grind my boy

Pyrotechnical Science - 2019-11-01

Pedro Trujillo yes indeed!👍🏼

Jim fakes - 2019-10-18

Where can I get my hands on some deterium gas?

Pyrotechnical Science - 2019-10-18

Jim fakes well if your budget is very high you can buy it in a gas cylinder from a company online (forgot the name) but you can find it . The more practical route if your on a budget is to buy heavy water then use electrolysis to obtain the deuterium gas. if you want a great website that will show you this in detail I’d go to fusor.net.

Jim fakes - 2019-10-18

Thank you also I loved your video with the magnetron gun keep it up.

Pyrotechnical Science - 2019-10-18

Jim fakes Thank you it means a lot! If you have any questions feel free to ask!

Ike Kennedy - 2020-10-15

Would you suggest to wrap the stems of the copper in wire coverings? I was considering doing that in addition some small plastic tubing.

Pyrotechnical Science - 2020-10-15

Ike Kennedy yeah, the less exposed wires the better.

Tanay Dakarapu - 2020-09-10

I know you can see the plasma, but how do you know fusion is happening?

Pyrotechnical Science - 2020-09-10

Tanay Dakarapu I don’t use deuterium in this reactor, it’s just a demo reactor so no fusion is actually taking place.

Unrell - 2020-08-02

I think I’m going to attempt to build this with no prior education on the matter

Pyrotechnical Science - 2020-08-02

I’d recommend definitely getting some experience with high voltage first. The voltages in this can jump easy and would kill you, so id definitely recommend not building this right off the bat.

Jason Kloss - 2019-08-20

Kristian Flaugher not thank

K L - 2020-07-31

You skipped the best part!!!

Asher Spector - 2020-07-12

This is a great video! I have prepared to create this fusor with a few tweaks. Would you be able to tell me what the dimensions of your glass chamber are? I have one ready, but I’m concerned the chamber won’t be large enough for two copper cages. Thanks in advance.

Pyrotechnical Science - 2020-07-12

I don’t know the exact dimensions, and sadly my chamber has broken since then so I can’t take any measurements. You can make the cages any size you want so size shouldn’t be to big of an issue.

Asher Spector - 2020-07-12

I’m sorry to hear your chamber broke. Just to make sure, would the size of the cages have any effect on the amount of atoms fused after adding fuel, or does it depend more on the electricity and a good vacuum?

Pyrotechnical Science - 2020-07-12

I’d assume the cages and the electricity are both limiting factors, kinda like how Volts and amps = power. And a very good vacuum is necessary for the fusion to take place beyond what my little vacuum pump could do. although this design is mainly meant for a demo reactor where deuterium is not added, if you were to do a design that actually fuses it’s best to use stainless steel chambers and parts.

Sr.Torrada - 2020-10-03

How high does the power supply voltage has to be?

Pyrotechnical Science - 2020-10-03

3000-4000 volts will be plenty if you just want to do a demo reactor. the thought emporium has a video where he uses microwave transformers to achieve this.

Sr.Torrada - 2020-10-04

@Pyrotechnical Science Thank you (:

ripalkys - 2020-03-27

Hey can i use hydrogen gas i saw a guy using it but i think the spark will detonate the hydrogen and light my house on fire

Pyrotechnical Science - 2020-03-27

You have to use the isotope of hydrogen deuterium, and it shouldn’t blow up cause of the lack of oxygen from the vacuum so the hydrogen can’t even burn.

Stephen Villano - 2020-04-01

@Pyrotechnical Science if you really have a budget, you could go with tritium gas. Of course, going whole hog that way, I'd boost the voltage up a bit more and use a lithium deuteride target. I figure around 125kv or so and neutrons should be detected, though I'd be hard pressed to see the detector. Way too many things could get interesting with a hard vacuum and hydrogen, with the addition of such high voltage.

Ezenbaatar Batjargal - 2020-12-08

What was the link of the fusers.net again?

aborjinovski - 2020-09-28

where can i find blueprints for this i want to build for myself to produce electicity

Pyrotechnical Science - 2020-09-28

Not worth the time, there’s not even fusion in this.

aborjinovski - 2020-09-29

@Pyrotechnical Science how can I find plans blue prints

Pyrotechnical Science - 2020-09-29

I don’t have any for this.

Isaac Kennedy - 2020-12-14

I tried using a neon light transformer and that sort of worked. The plasma only arced from one electrode to the other. I meant to also use a voltage multiplier but that didn't work either.

Юрий Алтунин - 2020-09-26

If there is no radiation - why Geiger counter registers radiation? My feeling - it is not radiation, but just ionizing of the air around Hi-Voltage parts of the machine.

Pyrotechnical Science - 2020-09-26

well I originally thought it was the high voltage causing a false reading, since the vacuum wasn’t that great I didn’t really expect any X-rays from it. But I ran the chamber with no vacuum and the reading stopped I also covered the Geiger counter with aluminum foil to stop any possible interference but it still gave a reading. While this doesn’t 100% prove its low energy X-rays, it’s just what I could do at the time. Although I still have some suspicion that it’s still HV interference.

Marco Pendoli - 2020-03-23

What model of vacuum pump did you use?

Pyrotechnical Science - 2020-03-23

TheRealPendols thank you! I really appreciate it!!

Stephen Villano - 2020-04-01

@Pyrotechnical Science how hard of a vacuum are you pulling? Looks like nitrogen was ionizing around the grid more than the deeper colored ionized hydrogen glow.

Pyrotechnical Science - 2020-04-01

Stephen Villano Not very strong, I was working with the bare minimum lol.

Stephen Villano - 2020-04-01

@Pyrotechnical Science not all that bare minimum, your improvised bell jar didn't implode. :)


We'll see, once this virus mess untangles my finances, I might try for a higher budget model. Hard vacuum, 125 - 150 kv acceleration and if the expensive element gods smile upon me, perhaps a lithium tritiride target for the deuterium to kiss fondly. If I get tons of neutrons and decent gamma, I'm onto something, if it melts, I'll have a patent.

Pyrotechnical Science - 2020-04-02

Sounds like a good project!

Renite HD - 2020-09-27

Hii how can i generate electricy?

Pyrotechnical Science - 2020-09-27

Renite HD you can’t with this

Renite HD - 2020-09-27

@Pyrotechnical Science ok thanks

Renite HD - 2020-09-28

Can you pls make one that i can generate electricy?

Pyrotechnical Science - 2020-09-28

Not worth the time, there’s not even fusion in this.

The Vault Boy - 2020-11-04

is this safe?

The Vault Boy - 2020-11-04

@Pyrotechnical Science i was gonna use this for my school investigatory

Pyrotechnical Science - 2020-11-04

If this is you’re first time with high voltage, I wouldn’t recommend it.

The Vault Boy - 2020-11-04

Its better with parental supervision right?

Pyrotechnical Science - 2020-11-04

matt matt only if you’re parents have experience with high voltage.

The Vault Boy - 2020-11-04

@Pyrotechnical Science good thing my dad is an engineer

ChechenKrygzleague 00 - 2020-03-16

8:09 3.6 roetgen, not bad, not terrible

Stephen Villano - 2020-04-01

Use tungsten for the grid, see the x-rays really fly!

Titanic Lover115 - 2021-01-04

Um thats not a good idea especially in a home inviorment AND OUT OF A 13 DOLLAR GLASS TUBE AND OTHER DIY ELECTRICAL PRODUCTS

Titanic Lover115 - 2021-01-04

@Pyrotechnical Science yeh but still fusion is really dangerous when your doing it yourself

Pyrotechnical Science - 2021-01-04

This isn’t fusion, it a demo reactor.

Titanic Lover115 - 2021-01-04

@Pyrotechnical Science i though I heard you say at the beginning it was fusion

Titanic Lover115 - 2021-01-04

Wait

Titanic Lover115 - 2021-01-04

Now I'm near the end of the vid now I can see its not fusion

Dante Johnson - 2019-08-20

Radiation Poisoning has entered the Chat

Jason Kloss - 2019-08-20

Dante Johnson thank

Pyrotechnical Science - 2019-12-21

This reactor only produces x-rays due to the vacuum and high voltage, but normal fusion does produce radiation in the form of neutrons mainly.

Stephen Villano - 2020-04-01

@Pyrotechnical Science never get fusion without deuterium or tritium, didn't see a source for the hydrogen to enter the chamber, so all you have is discharge of air in the chamber.

Pyrotechnical Science - 2020-04-01

Stephen Villano yes, this is just a demo reactor. AKA a fancy looking gas discharge tube.

been fox - 2019-12-15

How do you harness the energy?

been fox - 2019-12-17

Rad, thank you

ChechenKrygzleague 00 - 2020-03-16

@Pyrotechnical Science I've heard that there is a lot of research into Direct Transfer of energy, especially for fusion reactors for spacecraft.

Pyrotechnical Science - 2020-03-16

Dindunuthingwrong haven’t heard of that, you have any links to papers on it?

Stephen Villano - 2020-04-01

@been fox either by direct beta particles being drained from the reaction or more commonly, heat.
Let's face it, the majority of our really expensive ways to generate power involve really expensive ways to boil water.

Jameson 123 - 2020-09-01

Probably the same way modern fission reactors do using the immense heat to boil water and turn a turbine

xLesk - 2019-08-20
