Manky custom ioniser refurb with safety violation.
HTML-код
- Опубликовано: 4 окт 2024
- I made this completely custom ioniser (negative ion generator) for my mum and dad decades ago. It has a fairly beefy multiplier and an outlet terminal that allows different emitters to be plugged in. I can recall that I made a multi point emitter for air cleaning and a probe that emitted ions from the end for medical purposes.
It's been in use continuously since, mainly to keep a musty larder (food store) fresh by precipitating any dust out of the air and generating a tiny quantity of ozone to freshen it too.
My brother told me he didn't think it was working any more because the lights on it weren't lighting up. It was working, but was really in need of a good clean and refurbishment, so here it is.

Big Clive: the Bob Ross of electrical engineering.
It is almost disturbing how relaxing his videos are.
Love the GrayStillPlayz reference
"This is very dangerous!"... says the man who buys shoddy electronic on Ebay for a living.
Rene Schickbauer nahh.... That's just for fun and giggles....
Rene Schickbauer missed the whole point all together of this channel
Seems like you've got 62 official health and safety executives watching your videos, Clive.
As of this time there are a hundred and thirty-six health and safety inspectors. whom have seen this
@@jonathanfurtado3696 now 143, but I don't think they are actually WH&S personnel. More likely humorless wowsers with sloping foreheads. Wait, that's the same thing isn't it?
NAUGHTY NAUGHTY BEAR!
furry confirmed? lol first it was the bad dragon brick next its him callin himself a bear hmm
So far it looks like there have been 11 health and safety experts to view this video. :D
We are up to 35 now :)
Now 43. I didn't think they had that many employees
make that 42 limp-wristed toss pots
Now it's up to 99 .. wtf XD
105 now haha
Loved this! Thank you Clive....naughty 🐻!
The more of Clive I watch, the more I find myself loving him. Uniquely..... Clive
Thumbs up, purely for the Health and Safety violation!!! :-D
naughty bear
Yes I giggled when I suddenly pictured him dressed 'village people" style.
Bear or bairn? I'm not sure.
tis bear he refers to bears in his other videos
en.wikipedia.org/wiki/Bear_(gay_culture) i bet clive tells all his friends how naughty he is when filming himself........taking apart electronics.
I see. Yes, that makes sense. Judging from Clive's vocabulary and accent, he's spent a formative, post-pubescent period in the US.
Are bears also into small, dangerous, garish pink electronic appliances? Or is that just Big Clive?
I can verify that a 50 cap cockroft-Walton multiplier works on NA voltage. I just need to rebuild it and make a better emitter.
I've never once really understood a single one of your videos. they all just fascinate me.
I made a small one many years ago and used to sit it on a sheet of paper to collect the dust.
As a semi professional bodger of the wrangling of the slightly angry electron, I see no issue with your jerry rigged apparatus but don't quote me as I have been bitten by angry Electrons a couple of times
After he pokes it at around 5:27, anybody else see the lead on the 6th diode down on the right column start shimmering as if its arcing?
Yeah, I noticed that too! I figured it might have been a reflection or something though.
oh yeah
I never noticed that. Well spotted. I wonder if Clive will notice your comment and give us his professional opinion on what it was?
I never saw that but now I want to know.
Well spotted, that looks like it's going to fail soon, that will bring the final voltage down, to zero if it opens.
Why I must think about the health and safety video from photonicinduction...
Photon's awesome :)
Just checked out photon... couldn't take more than 30 seconds of it. That accent of English gives me the runs and pukes. God, no comparison with Clive AT ALL. YUCK.
What kind of fabulous bright yellow outfit is that? :D
It's a hi vis yellow hoody. The nature of my work means I have plenty of high visibility clothing.
It's the HSE appeasing outfit.
+bigclivedotcom still better than running around in dull black clothing all the time... ;)
Made a 5 pound purchase of a USB ioniser a few years ago. I bought a load of LED filaments after watching all the Big Clive videos on them. Actually makes a decent light for reading and runs off lithium power banks. It's Cockroft-Walton by the way which makes a good Geiger counter circuit with a high impedance speaker.
These are really quite fascinating little devices.
I made one of these, and messed with it until it became powerful enough to blow out a candle flame.
The key to it was the use of an accelerator plate behind the ion emitter pins.
Imagine that, a personal fan that doesn't have any moving parts :) .
I don't know much about electicity but find your videos very interesting.
Thumbed the video up despite your urgings to the contrary because naughty bears are badasses.
it's called villard voltage doubler. i'm currently playing with this in my 2 stroke cdi build. very helpful to get better spark.
We used to have an air purifier that had the needles sticking out in a sort of plastic cage. It worked fairly well but came with a damn fan and carbon filter to clean the air as well. Back then (before the Doctors got a hold on my old body) I had a difficult time getting to sleep, and uncommonly, white noise just bothered the hell out of me, so I told my good wife of 50 years to throw that damn thing out! She did. Now that I am doped up, I have a hard time staying awake at night, even before going to bed, with the noises of the house, and my good wife watching the television at a sound level that the neighbors call to complain about the gun fire when detective programs are on I sort of wish I had it back. I was thinking of trying to build one of these for our home but after seeing how many cells I would have to make for our 125 volt system I sort of put it on hold for awhile. Perhaps I will try to duplicate the one you built and see if that will work. I wonder if 400 volt rated 0.022 micro fared caps would work? I have at least a hundred of those little buggers that came in a combo pack from Electronic Goldmine.
Could you tell more about ozone generators? I thought ionizers with high enough voltage always generates ozone as well. (sure, ozone can be generated with arcs and AC corona too, but that is another subject I guess).
+hoggif Ozone is toxic and levels above 100 parts per billion are considered hazardous.
I thought some clarification between ozone generator and ion generator could be explained when they are describes as two completely different apparatus in the video.
Yes, ozone is very toxic. You also tend to get used to increasing levels and your nose will not tell you levels have risen quit high perhaps. Done that with large amont of corona in closed space, it gives you nausiness and perhaps a nasty headache as well.
So far, 25 officials in the Health & Safety dept. watched this video!
I thought it was a mains vape.
Hey, there's an idea.
Video request: a build-along for an American version of this!! :)
Gave a thumb up because I like naughty bears. ♡
Do ionisers really help with the "damp" smell? How would one find a good and cheap one on eBay? I.e. what to look for?
They won't solve dampness issues. That has to be done at the source, or if it's just ambient humidity then a decent dehumidifier will help. But an ioniser can help remove pollen, spores and dust from the air, and if a small amount of ozone is involved it will oxidise airborne contaminants at the same time.
Hi Clive. Loved the video but don't need an ioniser to leave a "shadow" around things in my shed there's plenty of dust for that!
I noticed you did not touch the needles at the end, even with the two 1 Meg 'safety' resistors in series with the ionizer output. This begs the question... how shocking is it?
If you approach the needles from the front it'snot too bad, but if you approach from the side then it tends to give you a static shock.
Working on the 50 capacitor arrangement here in America on 120v. I will let you know how well it works when finished.
Now the challenge is to scale it up and see if you can get measurable thrust :p
Lifters are not a viable earth-borne propulsion idea at all. Space yes. Gravity no.
61 health and safety professionals disliked this video.
I evilized a USB ionizer to increase the power. You see, there's a SMD resistor marked 105 on the output of the voltage multiplier, so I removed it. It now has a bit of visible corona around it in complete darkness. As it has sucha tiny output, that's pretty much not a issue in terms of safety. Might I add you should NEVER plug one into actual USB ports if it lacks cutouts under the transformer. Use a wall adaptor, or it can become a USB killer and nuke your MB. Might I add integrating one into the inside intake fan of your PC is a good idea. I made SATA to USB power cable so it would be connected to the power supply and not near data connections. I took a brushless fan and put metallic mesh of both sides of it, one side goes to the HV output of the ionizer, and the other to ground. The mesh is epoxied around the edges to prevent corona around the fan, and make sure it occurs between the meshes. The dust will attract to the mesh after it enters the case, and stick there instead of everywhere else. You have to vacuum or remove and blow out the fan once a month or so, but it really keeps dust buildup internally to a minimum. The ions don't bother the motherboard, provided it's a good 6in away and the grounded mesh facing the internals never disconnects.

Interesting, that's good to know. So they're pretty much the same circuit as in those little cubes that have the input wires and white output wires with bristles.
I have one of those as well, and they output a very nice amount of ions, and a very noticeable amount of air movement.
There's a barely detectable scent of ozone if the leads are too close to a grounded surface and it actually arcs. So I guess it could be used for ions or ozone.
Well made, and long lasting. Good job!

Sorry i just have to say: Dude I love your vids a lot, specially due to your accent. Makes me feel home again.
I miss Edinburgh. I was in love with your channel when I found your festival clips. I know you don't live there, but makes you very sympathetic to me nevertheless. I'd love to come back up there ;)
PS: I've never ever found those pens outside UK again :( They have a very nice ink ratio.
I've been living in Edinburgh for over a month now and it's a nice place. Feels way smaller than it is
Thumbs up for being a naughty bear.
Naughty bear ... Wearing yellow on RUclips ... Very Paddington of you :)
Hi vis shirt. Thanks to work I have no shortage of hi vis clothing.
I'm curious, does your work require safety shoes?
Yes, I usually wear either steel toecap shoes, rigger boots or just plain trainers if the work does not involve foot hazards.
Years back I had a pyramid shaped ioniser, and if you put your finger near it, you could see the arc, it also came with this weird test bulb to see if it worked, you held the yester a distance away, and if the lamp flickered, it was working
Sounds like an Amcor unit. Quite big and heavy because it had a transformer in it.
Yep it was an Amcor, it was fairly substantial, and after a while it would leave a black outline where it was placed. I think that could have been partly down to the coal fire at my parents house.
with some quick math, the output of a 30cap system is ~4500v at 220VAC (rectified being 220*1.4 = ~308VDC) so in America or another 120VAC country you would need 28 multipliers to reach 4760VDC which is 56caps
you naughty man. Excellent vid Clive
Looks like it should have been fitted with a pre 1984 mains plug with uninsulated live and neutral pins.
With one of those old plugs you never needed a quicktest/safeblock. Just hold the bare mains wires over the live and neutral outlet openings and plug the old style plug in. An instant very dodgy mains connection.
bob s Hello from freedomland!
That's one of about two things I don't like about the NEMA standards.
@bob s
it still works , you just need longer bare wires :-)
a better way is to use a figure 8 connector for two core or clover leaf (or kettle / computer) lead for 3 core and just push the wires in then plug it in , if the device your testing starts misbehaving you only have to pull the wires out to switch it off :-)
what a naughty bear
youre my favorite YT channel ,clive
Electrically-charged metal tends to oxidize more readily in the air. I had a metal-cased ionizer in my house for awhile, and it developed white corrosion all over it.
Are you sure that wasn't an ozone generator? A metal cased ioniser would be a terrible idea.
Purported to be an "ionizer" but I'm sure it produced ozone. I'm not sure what actually caused the corrosion, but your corroded electrode reminded me of it.
Amazing Work Clive. Very Cool Item. Keep up the great work. Nick.
Im gonna send this to all the Building Codes and Underwriter Labs officials and you naughty bear!!!
I'm a naughy bear too, I liked the video.
In my house, if you put ANYTHING down on a white surface and come back a week later and pick it up you'll see a white space with a grayish outline.
Oh if only could double-like the video for taking the piss out of H&S people, cos we all know H&S is just for people who don't know what they're doing... :P
HSE started off so well. It was sensible policies that saved lives. Then it turned into an industry and there are just so many freeloading safety experts now. I stopped working on construction sites when the level of ludicrous regulations and nasty power-hungry officials stripped all the pleasure out of site work. Carillion were the absolute worst.
bigclivedotcom
In my mind, there are no accidents, only ignorance, and I'm guilty of ignorance too given the times I've done stupid things and hurt myself, but, once upon a time, it used to be just common sense to not walk into a scaffold pole or not chop you hand off with a saw, but these days, yeah, too many people just leeching off the entire H&S thing, both as the H&SE enforcers and as compensation claimers, which isn't helped by them "Have you had an accident at work that wasn't your fault?" ads on TV & radio, it's amazing anything actually gets done these days with all the paperwork involved before you can even set foot on a work site... :\
The burden of useless people on the construction and engineering industries has pretty much added a zero to the end of the price of work.
bigclivedotcom
Indeed, it's sad when the Japanese can rebuild destroyed roads within days after an earthquake, but it takes months to fill in a small pothole here...
Then 2 months after they filled the pothole, it's back and bigger than ever. Then they have to send out inspectors who haven't a clue what went wrong and it turns into a committee meeting that calls for investigations that take many more months and the costs escalate ! It would have been simpler, cheaper and longer lasting if they did it the old way using people with common sense who knew how not to get hurt at work and if they did, they blamed themselves.
We have a major dust problem where I currently live. Where could I possibly buy one of these or make it myself if I wanted to? Great video, I always learn something new! :D
125 Health and Safety Executive reps have evidently viewed this video.
BigClive, could you make one out of a microwave transformer ? lol
That would 'ironise' anything including people that touch the prongs including flys
Probably not, if it was rated at the same voltage as this device and (crucially) had the same 2 Mohm series resistance.
I've made a few out of old CFL driver boards, and the generic "Ignition Coils" available via Clive's "usual suppliers" - e.g. - www.banggood.com/49CC-Mini-Car-Coil-Ignition-Motorcycle-Conversion-For-Two-stroke-Engine-p-1074109.html?rmmds=search. If you find the HV isn't high enough (VERY unlikely) a few extra Cockroft-Walton stages will suffice.
Given the current a MOT can supply I wouldn't trust a couple of resistors between me and it.
Since efficient ionisation does need a decent voltage, I'd suspect that using an MOT wouldn't be that effective, so you'd have an ineffective (yet potentially VERY lethal) "Room Ioniser" :-(
I enjoy your videos a bunch! Thank you so much! :)
Cockroft-Walton Generator
A Cockroft-Walton generator is a voltage multiplier that converts AC or pulsing DC electrical power from a low voltage level to a higher DC voltage level. It is made up of a voltage multiplier ladder network of capacitors and diodes. Unlike transformers, this method eliminates the requirement for the heavy core and the bulk of insulation, as the voltage at all the levels is identical. Using only capacitors and diodes, these voltage multipliers can step up relatively low voltages to extremely high values, while at the same time being far lighter and cheaper than transformers. Another advantage of such circuits is that one can also tap the output from any stage, like a multi tapped transformer. In practice, the multiplier has a number of drawbacks. As the number of stages is increased, the voltages of the higher stages begin to sag, primarily due to the zero impedance of the capacitors in the lower stages It is virtually impossible to feed the device off of commercial-frequency voltage, as this requires larger capacitors, which substantially reduces the overall physical size and weight indicators of the CW. The rectified current pulsations are also increased, which in some cases is unacceptable. Usually the voltage on the output is supplied from a high-frequency transformer, and then increased to the required value using the Cockroft-Walton generator. Cockroft-Walton multipliers can produce voltage of just several volts to several megavolts. Cockroft-Walton generators are used in many technical fields, like: Laser systems, High-voltage power supplies, X-ray systems, LCD backlighting, traveling wave tube amplifiers, ion pumps, electrostatic systems, air ionisers, particle accelerators, copy machines, scientific instrumentation, oscilloscopes, TV sets and many other applications that use high-voltage DC.

Brilliant as always. Whats the large red / black terminal box you with the N E L connections? Cant quite read the name on the front. Thanks Clive
Sparking the positive charge so we may drive the negative force to ground.
BTW falling water will create negative ions
Can you do an experiment with the ioniser to show common people what it does. Maybe a smoke test.
It seems like it would be useful to aim this thing at a positively charged screen (or even just a grounded one) so that all that dust and gunk has somewhere to collect, rather than just going all over the surface of everything.
I had my wireless router mounted on the wall and when I took it off years later there was a grey shadow of it on the surface. I'm guessing it's the same thing.
I wouldn't mind trying to make one for my room. Is there any kind of rough guide on how big of a multiplier and how many needles are needed to cover a smallish bedroom?
what is a good cheap ioniser?
So it's basically a fan without any moving parts, that works by invoking wind spirits?
I work in contract cleaning where dust is my arch nemesis.
🤔An ioniser might just be the thing in a couple of very dusty sites I know.
You can also do a 4:1 transformer here and use 1kv caps so only 15 of them would be needed.
Would be cool if someone designed a custom pcb for those stuck using 110v. I wouldn't mind an insanely large voltage multiplier to get the voltage I need to make it work. Would definitely save on weight.
It looks like there were at least 100 health & safety inspectors watching.
Now to scale it up to desk fan size for some super quiet room cooling via the immense breeze it creates :p
I don't want to see your power bill after you've scaled it up enough to provide an actual breeze. Although that level of ozone would likely result in lower internal body temperatures, as is typical in a corpse. But building that might be a good way to score a job interview with your local space agency.
Is the case you used from a fish tank vibrating bubbler? Could you take a bubbler to bits and explain how it vibrates and works? Thanks great videos!
I've taken at least one aquarium pump to bits in a video.
And a big 'hi' to Ralf
A dear child has many names... I recall a name for the multiplier as Greinacher - Villard.
At the point 4:10 This video got a thumbs up. Reason being. Health and safety is a load of bollocks. I love dangerous stuff and lastly for the fact of giving yourself a bollocking had me in stitches lol
+bigclivedotcom I believe you have drawn the Cockcroft-Walton multiplier section of your schematic with the diodes backwards.
+bigclivedotcom Ignore the diode comment. After simulating the circuit, I see that with the diodes pointing toward the supply the result is negative voltage output. And, with the diodes pointing away from the supply, the result is positive output.
Another very cool video, I might make an ionizer in the future if I get the chance. Wonder if I had a Grounded metal plate nearby to the ionizer if most of the debris would collect on that instead of everything else?
I should take apart another ioniser I have here that goes one step further. It has a dust collection plate with its own small positive multiplier that is theoretically a preferable place for charged dust to settle.
It'd be very cool if you do, and it is good to get some confrontation that the theory of a "Collection Plate" is possible.
Clive, do you have PCB boards for this project for sale, or do you have the Gerber file's?
I don't. It was a very long time ago. I'll have to have a hunt through old files or do a redesign.
Interesting you mention ozone generators, I've been considering picking one up recently since my wife's trunk got damp and is now quite musty. Not sure if it'd really do the trick to eliminate the smell, but I figure it couldn't hurt.
The only thing I don't like about ozone generators is the fact that the ozone kind of burns your lungs and nose. I've actually heard there's a correlation between ozone and cancer as well, so not something you probably want to breath in all the time. BUT for locking in a trunk for a few days to kill mildew or mold spores? Maybe.
High ozone levels (those you can actually smell) will quickly cause irritation to your membranes like eyes, nose and throat. It's basically an airborne oxidiser like bleach. It also corrodes materials like rubber and metal when in high concentrations. I'd recommend trying to clean any affected fabrics and then treating them with a mold killing spray.
Jesse Crandle If you can, park the car with the trunk open, facing the sun. Do this as often as possible. Sunlight does a great job of killing the spores.
James Potts I live in Florida, so life is a strange paradox: either everything is soggy wet and rotting or it's sun-bleached and crumbling apart. The plastic trim and paint on my car fades more and more each year, and yet the constant rain has made the trunk mildewy. I don't recommend anyone move here, and I'm not sure why so many people have lol.
Anyways yes, the sun would definitely help, but I'd have to keep a strict eye on it as it can rain at ANY moment. Flash downpours are an everyday thing here, sunny one moment, pouring rain the next.
Fulllllll bridge rectifier . Ah wrong guy 😂
0:10 " ...had a little cupboard under the stairs."
Nope, nope, not gonna do it. Not... gonna ... say it. Must...resist...
Those are some seriously disco sleeves, Clive.
Hi vis shirt. Complete with reflective tape.
So they can find your corpse easily after you inevitably electrocute yourself on your youtube show.
If most ionizers don't produce ions, is there one that you can recommend that actually work?
No BigClive ionizer factory?
got here as fast as i could
That wiring makes me feel very uncomfortable, even if I'm nowhere near it!
Hey Clive, Question, is that the same sort of thing as an ion engine. If you beef up the ionic stream, I guess the actual device would move across your workbench.
It would take massive ion force to do that.
You say many are ozone generators and not ionizers. How does one create ozone without ionizing the air?
My understanding is that rain creates vast quantities negative ions. I have always found that I sleep very well and heavy rain and I believe it's the negative ions that are responsible although at this point I can't say I remember how I came to that belief. I've often thought of building some sort of negative ion generator for my bedroom so that I could enjoy the effect in all weather. Anyone have any thoughts on this?
I've never heard of these positive effects of an ioniser. And especially an ozone generator, I remember in the 90s when they all threw out their old laser printers because they were generating ozone and it was considered a health hazard. This is fascinating, why can't we buy something like this? OK, 30 caps, 30 diodes and 2 high value resistors and one can build one themself (if one knows the circuit diagram), but still, this sounds like something every household should have!
What kind of medical application is the other probe intended to being used for?
The probe was based on research that showed that wounds exposed to a stream of ionised air healed faster. It may have been the sterile environment it created. Ionisers used to be very common, but the best type are not so easy to find now.
bigclivedotcom OK, so the best bet would probably still be to build one from the circuit diagram you showed in this video. The only problem I have with it is: In Germany, we have the normal EU plugs, and they are not directional, so it could be plugged in either way. What would happen if it gets plugged in the wrong way?
I used 20 stages on a 700 volt CT transformer from a tube amp I did the stile that uses bridge rectifiers
could you please do a build along video to make those ark lighters
Much more complicated than a average user can build.
I was having a really 'Thick-as-a-brick' moment trying to understand how these work. In my mind Live is at 220-240V(rms) and Neutral is at (ish) 0V (tied to earth at the substation end) so I was struggling to see how the circuit reversed to create the + - , - + alternating to make the diodes work. I then re-taught myself that it's actually the CURRENT that is alternating between the L and N wires which is when the penny dropped. Excuse my stupidness at this time, I have 'man flu' and not thinking straight right now lol
Id like to hack that black pyramid ioniser I have to put better pins on it :)
The 1M resistors also make sense now as they are a current limiting device and have no/little effect on voltage, like i said, feeling so thick right now.
Thanks for this vid Mr 'Naughty Bear' you always make me laugh and always teach me something cool in every vid :D
When you ground the AC output of a transformer at one side it is still AC, but one leg of it is referenced to ground. So with respect to actual ground it may seem like zero voltage either way, but to the other side of the transformer winding it still appears as alternating polarity. If that made sense.
Yeah that makes more sense buddy,for some reason I was spinning out not seeing the logical side of it. Many thanks for stopping my head spin :D Thank you :)
Could you add a discharge resistor to remove the "inconvenient" tingle you get from the pins after unplugging? If so where and what value?
You could add two one megohm resistors in series across live and neutral. Or kill two birds with one stone by adding an LED indicator like I did which will safely discharge the plug down to about 2.5V while also adding a useful indicator.
For 120V input, wouldn't you need only one more stage since it essentially doubles with each stage?
No, it multiplies the input by the number of stages, each stage has 2 capacitors and 2 diodes .
On a plug, are both the live and neutral pins on a sine wave or is it just the live pin and the neutral stays at 0v?
Would ionisers work better at controlling dust if there was a device emitting positive ions on the other side of the room? Presumably the positive-charged dust and negative charged dust would be attracted to each other and more likely to stick together and fall.
I'm not sure what effect that would have. It might just result in charge cancellation. You do get industrial ionisers for removing static charges that put out positive and negative charge to cancel out surface charges.
If each multiplier stage doubles the voltage, could us 120 Vac users just add another multiplier stage?
He does answer this in the video.
Oh ok I'm used to the typical voltage doubler that does double the output when lightly loaded.
@jmcinvale
it is only a doubler at the first stage each extra stage only adds the starting voltage to the end :-)
I love the smell of ozone.
I guess it has similar "charm" to other harmful habits, like smoking tobacco
MrJohhhnnnyyy and booze.
***** Yep, but sniffing ozone and smoking is similar concept :)
If you can smell ozone then your voltage is too high.
so is Oxygen.
Could you do a video of what bench equipment us have?
If the ionizer is causing a small breeze, could it be super-sized for use as a form of thrust in like a rocket or satelite?
Some of them used to turn small 'windmills' as a visual confirmation that something was actually happening iirc... don't think it's got much scope for earthly propulsion but you can make an ion drive that ionises xenon for use on spacecraft and they have a lot of potential.
Ion propulsion is indeed one way you could push a spacecraft. It's the sort of thing you'd use on something small and/or that doesn't have to accelerate very quickly. It's minuscule amounts of Delta-V, but if you don't care how long it takes, it's about the most efficient form of propulsion there is short of science fiction "reactionless thrusters." Note that you would still have to inject something into the ionizer to act as reaction mass, but it could be almost anything, and in very small amounts.
But if you've got any sort of friction, ion propulsion is useless. You probably couldn't scale it up large enough to work in an atmosphere, and even if you did somehow manage it, the power consumption would be atrocious and the ionization/ozone creation would be dangerous.
TheRealColBosch what about a craft that uses skates on ice? You wouldn't need to inject anything since you're within an atmosphere. and you could beam energy to the craft using microwaves. Just a thought.
No. Ice still has friction, and the air alone would be too much resistance for any reasonable setup. And again, you'd have to use obscene amounts of power, it it's possible at all. It'd be far more efficient to just use sails or a standard motor driving a fan. Even if all you wanted to do was push air around, a fan is a much better idea.
TheRealColBosch it must be a miniscule amount of thrust then. Still interesting!
Great Video :) Maybe I missed it, but what range does this have? How big can a room be at maximum, so an ioniser of this kind is effective?
Hello Clive, I have a question about this ioniser. How would you make this work with an EU plug that isn't polarised?
@DANGERTIM112
it will work any way round as its ac :-)
