    @SolarWebsite You're clearly confused in thinking that on large scale " green renewable energy" is an efficient power source.. Used as back up and reserve energy its fine.. Used on small scale house by house basis its Ok.. powering whole countries.. Nada.. Highly unreliable i.e Wind doesn't blow all day, sun doesn't shine everyday or every where.. Rolling blackouts are the norm and extremely high energy costs.. for those few idiots that have tried to use it on scale.. I/e California, and last winter in Texas.. theres failed. No no no.. The best power source would surely be Nuclear.. its clean and highly efficient.. but fusion would surely be great if they could actually do it.. Nuclear my friend nuclear.

    You can bet the moment anyone figures how to maintain plasma in the tokamak it will be patented and the intellectual property rigorously defended for 20 years as they drag their feet. The same as is being done right now for the flash graphene process that could eliminate all plastic and most other hydrocarbon waste materials.

    Hello there, Excellent videos. I'm happily retired and in my 70's, I used to work at the UofB in the UK designing and building scientific and electronic equipment and I thoroughly enjoyed every minute of it. Many people use such equipment to obtain results/qualifications etc but may not actually enjoy the workings of the apparatus. Similar to you I found my work fascinating and your videos are a reminder of how I felt before I retired. I'm looking forward to seeing more. Many thanks Chris.

  • MSivonen

    You always manage to talk like you actually know everything about the subject and have experience about it, and not like you just learned it yesterday. Very detailed explanations like behaviours of different plastics etc. Either you are doing amazing background work, or you just happen to know -everything-. Keep on enter-/educating us. Thank you!

    One of the things I always found interesting from an engineering perspective was the function of various vacuum tubes. The materials and different effects they have on environmental variables which gave them their characteristics . I've seen old labs where they were produced, it's amazing what they understood even 50 or more years ago. I'm surprised that something more didn't develop from those earlier technologies.

  • Mark Honea

    Perhaps something more did develop from those vacuum tube expirements, and it wasn't shared with the general public. Also, around that time, it is possible top military scientists were reverse engineering technology from crashed alien spacecraft, and that would certainly up the game. Just a thought. I too am fascinated by vacuum tube development and effects.👍

  • Philip Zheng

    Thank you so much for the presentation and all the clear explanations. I've subscribed your channel and try to learn more!! 33 years ago I worked on a plasma research project (sponsored by DOE) for my master electrical engineering degree. I designed and implemented a Langmuir probe to measure the plasma intensity. The system is fairly big in a donut shape which is made out of stainless steel. All the flange seals were in copper rings. After watching your video, now I understood why the copper rings was used instead of rubber rings.

  • M D

    Thanks so much for the awesome content, your channel rocks. I thought to myself at 16:40 it isn't negative resistance until it's plasma, and I feel there's a lesson to be learned here about negative coefficient of resistance. Does negative resistance exist in the universe in plasma's absence? Just out of curiosity, I love this stuff.

  • Tech Ingredients

    Tech Ingredients


    Thanks! The principle of negative resistance should not be construed to mean that the flow of electrons is accelerated or energy is gained. In a plasma the greater the current flow, the more carriers that are generated by that flow and the easier even more current can flow.

    EDIT: received the epoxy 2 days after this comment, I'm sure a coincidence but very happy to get it! Would have loved at least one email from them saying things were slow or something, but oh well. Probably easier since they take orders and then never deliver or respond. I ordered 2 pair of the thermal epoxy 6 weeks ago and nothing. Emailed them many times and posted on their website forum where others have the same issue. I really like the videos, clearly since I tried to buy their epoxy, but am now fed up with no response. I don’t mind waiting if I know what’s up, but now they’re intentionally ignoring us.

    Love the video and your teaching style is a solid 10/10. I've done my fair share of independent study... orders of magnitude above "fair" considering I didn't attend university 😅. I wish I'd come across your channel back when I was a starry-eyed nooby, but as a seasoned vet I'll say I appreciate how well thought out this is and how you cover the perfect amount of material. You hit all three key points in my opinion: you cover enough to satiate any fledgling curiosity, you clearly explain the inherent risks and dangers, but most importantly you leave a lot of the finer details just the right degree of vague. Someone with a passing interest will watch this and leave with a head full of answers, but to anyone who's clever enough to always have a head always full of questions will leave with ten by ten thousand more. Seriously great work and I thank you for it, only in part because when society thanks men like you it's so often mistaken as praise for another. You have such an impact on the next generation or bright minds, my hats off to you. P.s. and no, I'll not forgive the innuendo ✌😁🤙

    I love that you actually describe what each part does so I can learn how it works. Usually you see videos like these and they will skip over stuff they see as obvious and ill end up losing me along the way. You made this very easy to digest and understand. This example had me thinking that there must be some kind of a capacitor type effect between charged particles from the sun flowing over the Earth and attracting negative charges to the surface, is something that could be possible

    Great way of explaining the difficulty of fusion in layman's terms. I'm so excited for the ITER facilities to be finished. The plasma gun method also sounds pretty promising. This next decade should be the greatest leap forward in human technology ever. So much so that the advances in this decade will be greater than the entirety of our advances thus far. I mean, arguments can be made for some of the incredible achievements... and these upcoming achievements wouldn't be possible without the achievements of the past... but these upcoming achievements are going to completely change everything. We won't need to pollute the earth anywhere near the amount we've had to currently - and the capabilities will be infinitely greater. The introduction of fusion and superconductors on a large scale will be incredibly exciting

    As always very interesting and entertaining provided I have the time available, it always goes to fast. Thanks for sharing your thoughts and ideas. If you like science than you might also like sci-fi. I love when I see sci-fi creators randomly create a plot gimmick that could of actually been rooted in science, after watching numerous videos about thorium energy, I have concluded the engine in firefly was a molten salt thorium reactor, using the spinning action to provide the artificial gravity needed to operate the reactor in free fall and provide the power for the atmospheric engines meanwhile the leftover gasses from the thorium process provide the propellent for the ion engines. I would love to see someone with your creativity to actually put together a demonstration model, probably wouldn’t take you very long either. BTW fusion energy could be our greatest mistake, when have you ever known humans to be able to practice moderation, if given an nearly infinite source of energy we will devise the need for infinite plus 1 demand. We need all the hydrogen we have bonded to the oxygen we have to maintain life or else we will become the next ball of iron oxide in the solar system right after Mars. We don’t need thorium to maintain life, thusly it’s my pick for the future, maybe just a demonstration on the process to share the technology to the uninformed public. Stay safe, wishing you and your family the best.


    I'd LOVE to see some CVD (Carbon Vapor Deposition) experiments with all of this plasma gear. Maybe you could make some CVD diamond projects, like a DIY diamond heat spreader. Or apply a diamond coating to various substrates like copper.

    This is amazing. I was always fascinated by plasma phenomena, but never been able to understand it. Now that I have gone through electrical engineering university I have found the theory of plasma more clear. I also have question, so nixie tubes used for clocks are also using this plasma phenomena? And we should not forget about the fluorescent tube lamps that were very widely used before LEDs. I hope that plasma technology will develop further and efficient energy harvesting systems will become a thing in NEAR future. I would also like to see a very high quality and efficient plasma lights more widely used for lighting such as sulfur light that emits near perfect sun spectrum.

    As a technician with many years of high vacuum plasma equipment mfg and R&D ....This was the best and most thorough presentation I have ever seen. Most of my knowledge of plasma physics in vacuum was learned on the job and by being lucky enough to have worked directly with several PhDs most of whom were very patient and generous in imparting their knowledge to me. Thank you 👍✌

    Fantastic experiment!!! I seen it once when I was younger at school... I could never interact with the experiment itself, but it's asthonishing. Those "diamonds of light" there inside the tube, could be a macroscopic effect of the quantum world laws? Time to time I ever wondered if one could do an experiment where the quantum laws are predominant over the phisical, macroscopic laws world has?

    Excellent content as always; your work is truly valuable. I'm convinced that similitude rules out the viability of fusion power on any sub-stellar scale. Could you explain why you're so optimistic? Could you dispel the concern that ignition costs will always be more costly than capturable energy from fusion reactions on anything other than a very, very large super-planetary scale?

  • Spirit

    Great video! You made a small mistake describing radioactivity: Shorter half life means it's *more* radioactive. Even the simplest tritium-powered glow-in-the-dark keychain sticks can contain multiple *Curies* of tritium. This is why Uranium, even enriched, with a very long half life is far safer to handle than an equivalent amount(by weight) of tritium.

    re: "but both are still radioactive phenomena" Sorry, dummy, that's a dumbed-down interpretation. Embrace the word "radiation" as a verb rather than a noun and you might get the right idea. (IOW my 2-way radio 'radiates' EM energy BUT is not a radiation source, like Uranium.)

  • EgonSorensen



    @uploadJ - "Ionizing particles are one thing, UV EM "radiation" is another ..." - but both are still radioactive phenomena... "Alpha particles consist of two protons and two neutrons bound together into a particle identical to a *helium* nucleus. Alpha particle emissions are generally produced in the process of alpha decay, but may also be produced in other ways." -

    I still remember doing this experiment in high school several decades ago. we only did one gas however. Our teacher also used a magnet to bend the beam and plasma but only for a short time; he said as this is a cathode ray tube, it does produce some radiation and bending the beam towards the magnet also causes the radiation to redirect and exit the glass right where your hand is holding the magnet. Normally the radiation manly exits at the ends and you can just avoid being on either end to be safe. Oil burner ignition transformers are also a good alternative to the neon sign transformers; also center tapped and about (10KV and 20 mA) if I remember right. I am not sure if the KV is just one leg to center, or both together; it has been a while since I have dealt with them.

    Honestly this reminds me of when i had a 10mW HeNe tube laser and my first year of college we spent a number of nights shining it through prisms and plastic bottles of various textures and glass vessels to play with and watch the refraction and diffusion against the wall with the lights out. Fun times.

    High voltage vacuum experiments are one of the most interesting visual experiences for me and I would like to see more of them. One question by the way: What is the situation with these experiments with possibly emerging X-rays. I think the danger is not so high in this particular case - no high vacuum and no intense electron emission which is stopped abruptly like in a classical X-ray tube. But still I would like to know more about it and have a practical confirmation. Thanks for the great video and the absolutely detailed description.

    Thanks for all the detail! What would happen with H2O or CO2? Would the high energy electrons disassociate them or would the molecules be ionized? Would it all happen in one place or would there be bands of different colors related to the different ions? This is one of the best recommendations THmy has given me in a while!

    There are many infrared wavelengths generated by the molecular excitations. One of the most common and powerful lasers is the CO2 laser that emits at 10.6 um when it is energized in a tube much like the one we demonstrated.

    I have a question that I'm hoping you can explain. Recently while working at a factory installing a control system the maintenance crew came and got me to explain what they were seeing. They led me over to a couple of florescent fixtures that were on and pointed up at them. There were bands just as those in your glow tube. There were about 30 of them in the 8 foot tubes. (two tubes) They were moving in unison at about a half foot per second from one end to the other end about 1-1/2 inches (38mm) apart. They evaporated at the far end and a new one appeared at the starting end to keep the whole procession continuously moving. I understand most of what's occurring in your glow tubes in detail but I couldn't explain how those rings in a glow discharge created by an AC current would favor moving in a particular steady-state direction. Any Ideas?

    I'm very happy you talked about the striations. I noticed them in the fluorescent tube lights in the underground trains where I live, something interesting about them though is thst they are not static, but they appear to move along the lights (not sure if it's thst they're actually moving, of it it's thst the wavelength is changing and that makes them appear to move?). Do you know what may cause the pattern to not be static? The behaviour of the striations is not the same within all the lights within the carriage, nor is it consistent - it seems to ramp up and down during the journey. I pressumed its a function of the condition of the light and maybe when the trains are accelerating they have less power to provide to the lights? But I've never found a satisfactory explanation of what's going on...

  • Af0ulwind

    I will have to watch this again and again to get some of this down before playing with it... On other subjects though, you mentioned fusion and the methods using high temps and lasers as well as the magnetic confinement and the requirement for the lasers to cool down over a long duration of time... I tend to believe a lot of the reasons for a need of high temperatures may have a lot to do with a lack of understanding on magnetic forces and the interactions of charged particles. I have been following some of the developments in Tokamak reactors such as ITER and think they could greatly benefit from a change in structure and shape of their design. i have thought about it a few times and think an incorporation of aspects from a focus fusion reactor and a set of multi tired electromagnets could potentially change the temp requirements by improving the electromagnetic isolation of charged particles as well as shielding, and the method of colliding the different clouds of particles through sequential pulses of differing tiers in the magnetic isolation. perhaps sometime if you are interested we could discus further in a more private setting?
