    well, you need to overcome the force that repels atoms and usually keeps them from merging with each other. basically, the heavier the elements you want to fuse together, the more force you will need to get them to merge. our giant nuclear fusion reactor, the sun, can only merge elements up to iron. heavier elements are born in supernovae's r-process. if you're really interested, read on wikipedia about:
    - the sun
    - nuclear fusion
    - supernovae
    - nucleosynthesis
    these keywords are a good start!

    you can get fusor equipment at e.g. wiederlabs-dot-com, and gas companies such as LINDE will sell deuterium. a tiny bottle (that will last for years with fusors) is about $200. a vacuum pump, you'll find by googling, sometimes ebay has some good ones.

    To those who are whining that this isn't home-made, let me tell you something. I know this person via internet, we are part of a loose collective of fusor builders, and I have also made one of these (I believe I'm the leader in Q and output currently) myself. Search youtube for a Vice video with the terms fusion and gunsmith and you'll get mine. Does that mean I smelted the iron and fabbed all the stainless steel, made my own turbopump and so on? Heck no. This kind of stuff is often available in high-tech scrapyards, university auctions and so on. Do you make your own axe heads? Of course not, someone else does that part for you. The specialized parts, yes, we make those ourselves, using the normal machine tools. Doh.
    Did the original source of some of the high tech parts assemble these parts into a fusor? No, they originally had some other purpose when bought new by someone else in most cases. Do you do the masking and processing of the silicon in your computer? Get real, one uses what one can get to get to a result...she is sharing hers, I share mine, let's see yours.
    Or, STFU. You can check dcfusor on youtube for my own efforts. I didn't make the lathe, either...would you have? Really?

    sorry if that was a bit confusing. 10^-7 torr is the pressure after initially removing the gas / air in the fusor.
    AFTER admission of *deuterium*, it is indeed in the *militorr* range. :)

    it'll be fun once you get over the basics, as it's pure logic and easy to build up upon. it'll be extremely awesome and with always new things to explore, like zooming into a beautiful fractal infinitely, the big and the small will be equal (like the universe and an atom), and all will be logic and bliss.

      Hi where can we learn about its basic. I mean nuclear fusion basic?

  • @bionerd23
    @bionerd23  11 років тому +1

    yes, you could do that. however, the neutron flux is way too low in one of these fusors; 10^7 neutrons/second is not a lot. it can activate stuff for a while, but it'll cause too few nuclear reactions to have true samples, e.g. of Co-60. Co-60 is usually produces with fission reactor neutrons at much greater flux intensities.

  • @bionerd23
    @bionerd23  13 років тому +1

    @lollazers
    depleted uranium is another word for uranium 238, and that is not fissile material. however, bombarding it with fast neutrons would result in U-238 -> neutron capture -> U-239 -> beta-decay -> Np-239 -> beta-decay -> Pu-239. it produces plutonium, and as has been done in "fast breeder reactors".
    bombaring fissile U-235 with thermal neutrons would result in fission and additional neutrons, however.

  • @ThePolywellGuy
    @ThePolywellGuy 11 років тому +5

    You should stress the fact that a fusor uses an electric field to do work on atoms, to heat them to fusion conditions. That is the key physical mechanism. Otherwise this is a great bit of work. I really like your explanation.

  • @VestedUTuber
    @VestedUTuber 12 років тому +1

    So, to break it down...
    1. Create a strong vacuum
    2. Direct a strong electrical current through said vacuum
    3. Inject deuterium gas into the path of the electrical current. This will ionize the deuterium with a positive charge
    4. The resulting high temperatures will cause the deuterium nuclei to combine into Helium-4 nuclei
    5. The Helium-4 ion ejects a neutron or proton, creating a Helium-3 ion or a Tritum ion and giving off massive amounts of energy, or it just ejects a gamma ray.

    as i stated in the video, this is not my fusor. and, well... it's an experiment rather than a power plant, but it does produce sufficient heat to melt its own electrodes if run for too long or at too high voltages (~100kV = runtime of much less than a minute, or the reactor's inner electrode melts).

    so the silver acts like a 'control rod' of sorts? how do you know when it's absorbed it's limit? does it get coated in cadmium and you can scrape it off, or does it aersol into the air? I suppose this is based on surface area, or does mass play a part? How do you know the ratio of converted helium vs hydrogen again, which could seed more of the reaction. I always wondered how a 'net positive' reactor actually works in regards to what is happening under the hood. I know this is just an experiment, but in a perfect world, how do you know when to input more fuel?

  • @lollazers

    One quick question.
    Since this fusor can force nuclear transmutation, lets say we replace the silver in this experiment with Th 232. Will it transmute into U233 and release beta particles and lead to a Thorium fuel cycle or is the neutron flow too slow for it?

    Hi, Illy. Nice video on a great topic !
    However, your pressure seems off by a factor of 1000 or so.
    In the vacuum trade, a "micron" is a micrometer of mercury or (very slighyly more than) a millitorr (mTorr) NOT a microtorr. One pascal (Pa) is about 7.5 microns. You probably mean 1 or 0,1 micron, which is already an impressive vacuum. I'd have a tough time believing your figure of 0.001 or 0.0001 micron ;-)

    Why does everyone treat protons as hard static charged balls and try to bash them together, when we know that they are *dynamic* , moving.
    Perhaps, if they can be made to *engage* at just the right velocity (v) , the right spin characteristics(s) and at the right phase (Φ) in their spin, they may just _pull_ together.
    With a dynamic proton, the Coulomb barrier looks less like a wall, and more like a charged coiled ball.
    A spinning ball with a random chance of (say) 1/100,000 chance meeting another proton, with just the right combination of v,s & Φ .
    Perhaps if we work at precisely controlling v,s & Φ the odds will start to approach 1:1. and power, containment and energetic neutron generation would lessen?
    Food for thought.

    Awesome. I'm looking to make one of my own.

    You can't use these to generate electricity, these things way more power than what is put out.

    They look a lot like the weld produced by a spot welder, usually used for two thin metals side by side sandwiched between two contact points. (instructablesdotcom/image/FPCM3RHFJADQC4B/Building-the-jaws.jpg). Looking more closely at the picture, this looks like a metal lid of some sort around a spherical body, so I would say it is composed of two disks spot-welded together. When you machine the metal, it usually looks like this. I built and tested a spot welder with a friend a couple years ago.

    i was wrong, not illegal, but still is there any chance of a critical failure in the reactor? how much does it cost to build this? approximately

    uh yes. i have some 30 videos or so up about my chernobyl tours. just check out my channel if you're interested. :)
