How to Make/Build a Lifter or Ionocraft

[@RimstarOrg]

Back in the day when more people were playing with lifters I recall at least one person who got a dirigible shaped helium balloon and attached a lifter to it with controls for tilting the lifter for steering. So the balloon was for the lift and the lifter was for the propulsion. Worked great. And I'm glad you liked the video. Thanks!

[@RimstarOrg]

Cool! It became very popular with more of the mainstream when MIT released a paper around a month ago about ionocrafts (which is what lifters are) and their efficiency. This video was embedded on a large number of websites since it was the only clear how-to-make and demonstration one out there. Thanks for letting me know, Grant.

*REAL* craft would lift itself. this POS won't move if it was attached 2 the power supply. RIP

[@seb_gibbs]

You said it works if connected to positive or negative? Which is very interesting, as it means its not Ions that provides power to the lift.

It's amazing how many innuendos you can get out that part of the video with terms like discharge stick, balls, skirt, safe. I realized it as I was saying it but left it in anyway. Gotta have some humor. :)

[@RimstarOrg]

I made the power supply that I use so it's definitely possible to make one. If you can still find an old tube style computer monitor then you can adapt that. I put some links in the description below this video to pages on my website where I show various options. And I'm glad you like the video! Thanks for watching!

[@Salafrance]

Nicely done. I'll have to try this when I finally have my flat sorted. Another project I'd like to try is a variation on this theme: Create a disc with a series of concentric wire circles. Power them such that they sum, centre to edge, but never exceed the breakdown voltage between adjacent concentric circles. Arrange a surface with a dense population of strong magnets below the disc such that there's a toroidal field, again concentric with the disc, with the field lines passing vertically through the body of the disc. The idea is to create a combination of magnetic and electric fields such that a Lorenz force acts on the air ionised by the circular electrodes, causing it to spin (concentric with the disc) and centrifuge outwards from centre to disc edge; in effect, creating a vortex. I'm curious as to how much aerodynamic lift you could generate in this way...

Your attention to detail and safety is awesome. Thank you for the demonstration.

[@RimstarOrg]

It is. One pole of my psu is HV positive with respect to ground and the other pole is ground. I prefer to connect the skirt to ground since the skirt is closer to the table and the table is also ground. But it can be done either way. Theoretically, you get better results with the wire connected to positive, but the actual performance is hard to measure.

[@RimstarOrg]

Thanks for the suggestion, Paul. I've thought of that approach but that just gives the lift-off thrust, though I guess you could keep adding mass until it can't lift anymore. By the way, such a challenge was done back in 2003 and was the 100 gram challenge, to lift 100 grams in addition to the weight of the lifter. Do a search on google for "100g payload lifter".

[@RimstarOrg]

I suspect you're remembering Major de Seversky's ionocrafts. From the videos and photos they still look pretty lightweight though. Before these triangular lifters came along I made one using aluminum fly mesh instead of the skirt. It worked. Though it looks like de Seversky used a bunch of sharp point instead of the continuous thin wire.

[@DigGil3]

When I built my first lifter I was having an hard time making the triangle ones like yours work, so I decided to build an hexagonal one because I had figured a way to use less wood per triangular section that way. I guess the more triangular sections, the less would (by comparison) is needed!

[@RimstarOrg]

Re the ozone, the room was ventilated. If you run this for only a few minutes and not often then it's not that harmful. Ions around a sharp point will spread out since they repel each other. But to become ionized there's usually an electrode with opposite polarity nearby. That's the foil skirt in this case. We don't want the ions shooting down to start with since we want an ion cloud for the foil to attract upward to. They will move down because of the foil though.

[@RimstarOrg]

In this power supply the negative is connected to ground and is connected to the skirt. So the negative is at the same potential as the Earth ground which is ultimately connected to a pole stuck in the ground in the backyard. The positive can be as much as +30kV relative to that. If the ground truly has the same number of electrons as protons then you could say it's not negative as all, in which case I have HV positive and 0V.

Putting some close to each other is ok as long as the structural requirements don't weigh too much. What I'd really worry about it the weight of the gyro sensor or whatever type is needed, making sure it safe from the ions and high voltage (which may mean more weight for structure), and how to communicate with the sensor. If it's a feed wire then that'll drag down on the lifter, if it's remote control then that's added weight. A lot has changed over the years. It may now be possible.

You can buy a power supply, or you can use an old computer monitor, one that doesn't have power saving features. There are links in the description below this video for both those. Some of the very first triangular lifters actually used a very large Van de Graaff generator, one with a dome that looked to be around 12 inches in diameter, though I've never tried it myself or heard of anyone else doing it since.

[@kajallison8896]

[@RimstarOrg]

It's really high voltage with high current too. The voltage need only be enough to create the necessary electric field across the given gap size. The current is what provides the electrons for ionizing the air (or takes them away depending on your polarity.) So 26kV which mine is supplying, plus more current would allow larger ones to fly.

If you're getting arcs then the wire should be moved farther from the aluminum foil. Mine are 3.5cm at the closest. Also try playing around with the wires that lead to the lifter. Arrange them so that they don't restrict the lifter from lifting up. You can lift the lifter by hand to get an idea of if they're holding it down. Also, it has to be as lightweight as possible. Mine are only around 2 grams. 15kv is a little low, but don't give up yet.

[@unvergebeneid]

RimstarOrg I didn't keep looking. I guess when I ever stumble upon a high-voltage power supply, I will get back to this.

[@RimstarOrg]

With the lifter we want unidirectional thrust. So the bare wire does the corona discharge (i.e. it ionizes air) and the smooth foil skirt is attracted up to the ionized air. The fact that it's smooth allows it to build up a surface charge, or high voltage with respect to the ionized air, so that it can be attracted to the ionized air. If it discharged instead, then it wouldn't build up the surface charge and it wouldn't be attracted.

[@SciHeartJourney]

This reminds me of working with CRT TVs or monitors. You can feel the hair on your arms moving!

[@RimstarOrg]

It's a very efficient design in terms of a weight to lift ratio. Lifters have to be extremely lightweight and this triangular shape uses a minimum of material. A good shape is one with a hole in the middle but it's harder to make a lightweight cylinder. Two sided wouldn't have a hole. Four sided required more material than three sided.

The very thin, uninsulated wire acts like a sharp point. When you use high voltage with a sharp point it ionizes the surrounding air. The foil thickness doesn't matter but the fact that the edge facing the wire is smooth means it doesn't ionize air, or not much. Instead, the foil is attracted to the cloud of ions that the wire made, and so the whole thing rises up. At the same time the ions are attracted downward, producing a noticeable downward ion wind.

[@RimstarOrg]

John Bump Yeah, the part that takes time is finding a suitable power supply. Once you have that, the lifter takes a half hour or so. Just make sure you try it in the dark. Seeing where the purplish corona is makes all the difference in getting it to work.

[@RimstarOrg]

John Bump Oh, you need a much higher voltage and current. Mine takes off at around 25kV and 250microamps.

[@vladokvk]

Can I use 100kv AC? It is real problem to rectify it

[@RimstarOrg]

Vladimir Knežević You need DC or pulsed DC. AC won't work because the ion wind will just keep reversing directions. It wouldn't get off the ground.

[@RimstarOrg]

The GRA 10 supplies up to 20kV. My lifter didn't fly until 25kV, so I can't guarantee that it'll work. They are fairly reliable and knowledgeable people, so it may just take a little playing with the lifter and care with the wiring leading to the lifter to minimize losses. The GRA 10 requires a 12V, 3amp power supply. I'd just use an adaptor, one of those things you plug in the wall that puts out 12V DC. There's also no fuse so either add one or use resistors as I point out in my video.

[@bharathpuluru7050]

how much voltage is needed to lift an avg.human? please reply me

[@MikaelMurstam]

bharath puluru it doesn't work that way. More voltage does not mean more lift.

[@RimstarOrg]

bharath puluru It would require at least a million volts but also with a lot of current. The ionocraft would also have to be around the size of a house and require protection to protect the human from the high voltage/current. It's not practical.

[@saikumarreddysama5261]

RimstarOrg oh! then how does satellite thrusters work?

[@MikaelMurstam]

No it could work with just 30kV. The voltage is not that relevant. You just need enough voltage to ionize the air. To prove this, just imagine a lifter running on 30kV. It has a thrust to weight ratio larger than 1. This means you could use a million lifters to lift something heavy, all running on the same voltage. It is the amount of ionized air that counts here. The amount of total thrust. Sure a million volts would increase the thrust, but you only NEED 30kV as a minimum

[@RimstarOrg]

sai kumar reddy Sama Some satellites do use ion propulsion with xenon gas as the propellant for moving around while in orbit. But they're not being lifted against Earth's gravity so the thrust can be much less and the acceleration is very small, so the satellite moves and can get up to high speed (if needed) over a longish period of time.

[@RimstarOrg]

@mrnewagemotor I'm with you in thinking that it requires an atmosphere. However, some experiments have been done with high vacuums in vacuum chambers that still show a little movement - not enough to lift them but enough to make them turn a very low friction rotor at slow speed. But I still leave room here the movement being due to the ejection of electrons, or ejection of material from arcs, ... I wouldn't call it conclusive without a lot more testing.

[@hewhowaits8991]

When you are currently playing Steins Gate and wonder what a lifter is, then watch it and let your imagination run to design some time machines blueprints... This too must be the choice of Steins Gate... El Psy Kongroo...

[@RimstarOrg]

The fact that the wire has a small diameter and the foil is smooth determines the direction of airflow and lifter movement. The polarity has some effect, but is secondary. Any other wiring between the two would have the same effect as decreasing the distance between the two and result in more charge flowing directly between the two, shorting it out and making it no longer work. People have gotten better performance by using DC pulses instead of straight DC.

[@suoppsdn9751]

Do you have any suggestions or opinions why they lift? I know the MythBusters said it was because the wire is vibrating so much it causes lift because it was vibrating the air around the lifter, but somehow that doesn't sound right to me. They tried to prove their point by placing the lifter in a container that was vacuumed of air to prove it wasn't defeating Gravity, and it didn't rise in an atmosphere vacuumed of air. Correct me if I am wrong. What is at rest will remain at rest unless acted upon by another force, and what is in motion will stay in motion unless acted upon by another force. By removing the air they cut out the force of buoyancy lifting something that was at rest. Before they removed the air the force of buoyancy help lift the lifter. Am I right or is MythBusters right?

[@RimstarOrg]

+Steve Rabon Really? That was Mythbusters' theory? I'm surprised. It's just plain old ion propulsion. Here's my explanatory video kzbin.info/www/bejne/ZmKpaYlrfs11a80. And here's a smoke test video I did a while back kzbin.info/www/bejne/goCqcpSFl9iBask.

[@suoppsdn9751]

Thanks; why didn't it continue to move in a place that was vacuumed of air? Shouldn't it had moved without the absent of air?

[@RimstarOrg]

+Steve Rabon Because it's basically a jet. It takes air from the top and pulls it down. That's the action. The reaction is that the lifter moves up. If you watch my ion propulsion video that I gave a link to you'll see that air is needed. You can even see the moving air in the smoke test in the other video I gave a link to. I didn't see the Mythbuster episode so I can't speak about what they said.

[@suoppsdn9751]

OK so it ionizes the air?

[@RimstarOrg]

Steve Rabon Did you watch either video I gave a link to?

[@RimstarOrg]

I think you need at least 30kV but I seem to recall reading once years ago about someone using single digits kV. If you do try, you'll have to put the wire much closer to the top of the foil skirt due to the lower voltage. Best if the distance between wire and foil skirt is adjustable so you can try different distances. Make it as lightweight as possible too.

Sorry, I somehow missed this comment of yours. It works with the top wire positive or negative - this video uses positive, my other lifter video uses negative - but I think I recall it works a little better if negative (I could be remembering wrongly - something for your science fair experiment to test!) Alligator clips are heavy. You can use them as long as it's where the lifter doesn't have to lift them.

[@DuhDaDuh2]

12:38 for the ladies

[@kajallison8896]

Hahah

[@RimstarOrg]

The thin wire acts like a sharp edge. The electric field near a sharp edge is very strong. This strong field either leaks electrons (if the wire is negative) or rips electrons from nearby atoms in the air (if it's positive.) This results is ionized air near the wire. This ionized air is attracted to the field around the foil skirt and is what starts off the whole ion wind that makes the lifter fly. The wire must be uninsulated and as thin as practical. Mine was 30 AWG (American Wire Gauge).

[@callmebuffthighs6723]

does anyone think this could be implemented into somebody's boots or something so they could fly around like iron man?

[@RimstarOrg]

That's a good sign as far as the lifter is concerned because that means ionization is going on. But you should have some ventilation if you'll be breathing it a lot, though it takes a alot to be harmful. To see ionization, turn out the lights and you should see a purplish glow around the wire in places. The less powerful your power supply, the dimmer the glow. You may also hear a hissing sound.

[@terradragon9192]

"touch the balls..." LOL XD

[@RimstarOrg]

It depends on the voltage and how light your lifter is. The lighter your lifter, the lower the voltage required. The lower the voltage, the smaller the distance can be. Humidity also has an effect. So I don't have any specific numbers. In my "Lifter Voltage/Current and Smoke/Airflow Test Measurements" video my 2 gram lifter lifted off at 26,000 volts, with a distance at one corner of 2.5 cm and 4 cm at another corner. I suggest making the distance adjustable like mine.

[@x2thel]

"If you don't have balls like that to touch, you can touch the skirt"

[@RimstarOrg]

There are many different high voltage DC power supplies so it depends on which one. Ones that have a flyback as their last stage put out AC but ones that have a Cockcroft-Walton voltage multiplier as their last stage are rectified and put out DC. Mine has a flyback followed by a Cockcroft-Walton voltage multiplier so it's rectified and hence is DC.

[@dragonzbw]

But he's a guy

I've tried to think of ways of measuring the thrust but so far have been unable to. As for working at lower air pressures, tests have been done in vacuum chambers at very low pressure and they did move, though with clearly far less thrust.

[@RimstarOrg]

It's a form of ion wind. The thin, bare top wire ionizes a large volume of air at the top. The foil skit is charged with opposite polarity and has a smooth top so it doesn't ionize much air. Since the foil skirt is opposite in polarity to the ionized air, it's pulled up to that air. Meanwhile that air is pulled down. Not all of the air makes it down since it collides with other air molecules. Watch my "Lifter Voltage/Current and Smoke/Airflow Test Measurements" video to see the air in action.

[@RimstarOrg]

@mrnewagemotor What do you mean by "atmospheric anti-gravitation"? I've done wind tests back in 2001. It's basically a jet (see the link in the description, the flame test.) The top wire creates a cloud of ionized air and the foil skirt attracts the ionized air down. The skirt doesn't ionize much air because of the rounded top edge. If there is an anti-grav effect, it doesn't play a significant part. I should do another video measuring voltage and current to answer your second question.

You're welcome. Thanks for watching it. In answer to your question, the conductor would only disintegrate, or melt, if the current flowing through it was large enough. The current in this case is too small, even though as you point out the conductor is thin, so that doesn't happen.

[@RimstarOrg]

If the rips/holes are near the top of the foil then it's the same as the foil having some sharp edges. Instead of the foil holding onto its charge, it will start losing some and ionizing air. The voltage between the foil and the wire-produced ion cloud will be lower and the lift will be less. I usually see this if there's a lot of sparking between the wire and the foil. The sparks blow tiny holes in the foil and the lift performance eventually decreases.

[@takumifujiwara1931]

[@RimstarOrg]

By the way, I give links in the description below this video to three different power supply options, one of which is the monitor power supply. And if anyone uses the convergence and deflection coils as Gary suggests, make sure to remove the thin enamel insulation. Gary, how did you remove the insulation, a lighter?

[@RimstarOrg]

I don't know enough about taser batteries to say but tasers do seem to produce quite a strong, continuous arc, so maybe.

[@RimstarOrg]

If the distance is too small then it can spark, which ruins the effect. Beyond that, I'm not sure if a bigger distance is better or not.

[@RimstarOrg]

I've no doubt shape would make some difference and as you point out, there are many variations. But I don't think any one person has done enough variations to rigorously say what's best. Oh, pulsing the high voltage can also be an improvement. The best list I know of is on the blazelabs website, in the EHD Thrusters menu, Thrusters Performance page. No one's gotten close to lifting the power supply and until some kind of super light power supply tech is invented, they probably won't.

[@RimstarOrg]

If your cloth is light enough and you have enough current feeding your needle, you might get a reaction. You'd probably have to do quite a bit of trial and error first. I also find cloth hard to charge up. Thin nylon or acrylic might be better. But you can do without the cloth since a sharp, negatively charged needle will emit electrons on its own due the the strong electric field at the needle tip. That's what I did in my "Ion Wind Rotor" video.

[@RimstarOrg]

The power being used to maintain its flight is around 7 watts (26kV x 275uA) and the lifter weighs around 2 grams, so 3.5 W/g. See the "Lifter Voltage and Airflow Tests" annotation link at the end of this video to see me making these measurements. However, I've seen as good as 1 W/g where an 85g lifter lifted itself plus an additional 100g. Do a google search for "experiment 14 100g". And I recall a Japanese one that was room sized. Still couldn't lift its own power supply though.

[@RimstarOrg]

Fifty dollar for crazy glue would be much more than I'd spend too. The glue was $5, the price tag on the bottle showed $4.99. I'm not familiar with stun gun output so I can't say if a modded one would work. As well as the high voltage, it does need quite a bit of current to feed the ion wind. In my "Lifter Voltage/Current and Smoke/Airflow Test Measurements" video I show it using 26kv and 275 microamps. There's a link in the description for this video if you're curious to see the measurements.

[@RimstarOrg]

I know what you're getting at but terminal velocity applies to an object that's falling, not under power. If a jet is flying downward under power then it can move downward at a higher velocity than it's terminal velocity. A lifter under power is just like the jet under power. So I'd imagine an upside down lifter, under power, moving downward would move down faster than if it were not under power, even assuming a heavy lifter that wouldn't be blown sideways in a wind.

[@RimstarOrg]

;-) You need a high voltage, reasonable high current power supply. There are some links in the description below this video to my webpage where I show how I made my 30kV power supply and another link to how to use an old computer monitor as a power supply and also a link to where you can buy one (make sure it's output is high voltage DC.)

[@RimstarOrg]

You'd need something that still very lightweight. This lifter is only around 2 grams. The only thing that comes to mind is carbon fiber, which you can usually get in hobby stores that sell radio controlled planes. And I guess you can find it online. I don't have experience with it so I don't know if even that is light enough or what kind of work is involved in making parts out of carbon fiber. I know there are also carbon fiber rods.

[@RimstarOrg]

I want to do the same thing. Unfortunately I'm not aware of any way of hovering off the ground like iron man does with his small repulsors. Ionic thrusters won't do it. In fact you're better off looking toward chemical rockets.

[@RimstarOrg]

The experiment was done with pulsing from 0 to 100Hz. 70Hz required the least power, 17.72 watts, 14.59Kv RMS and 1.22 mA RMS. But you can experiment to find what works best for you. It can't be alternating. It has to be DC pulses. You can see it at jnaudin.free.fr/html/lftphv.htm

You could try making a high voltage power supply using an old computer monitor. I have a link in the description below the video that leads to my webpage where I talk about how to make a high voltage power supply using a computer monitor.

Hmmm... Interesting idea. Because of the weight issue though, about all you could lift would be the sensors. The comparitive circuit and everything else would have to stay on the ground.

I had such crappy math and physics teachers. I am not surprised how ordinary people build crafts u would never tought people could build outside an lab hidden for the mass. Thx for the video ❤

I thought they already were used for cooling systems. I haven't read the study but I've read an article about it. Sounds like there might be renewed interest.

Just made one of these using coffee stirring straws which were lighter than balsa and won't immediately catch fire when I inevitably jack the power up to make pretty coronas and shorting arcs :)

[@RimstarOrg]

I don't think so. And x-ray requires a high energy electron hitting a heavy element like tungsten (atomic weight 183.84). The only time there are high energy electrons in a lifter are if you have an arc between the wire and the aluminum foil. Aluminum's atomic weight is just 26.982. But I don't know if there's enough energy in the electrons during the arc or if aluminum is too lightweight. I've never heard of there being a danger.

It gives off ozone. Some say that large quantities of ozone can be harmful. Just use it in a ventilated room and you'll be fine. When I'm filming a lifter I have to shut all windows due to sound issues, but I open them afterwards and run a fan and I've had no problems.

I don't think it can be scaled up to lift people off Earth to get to space but it is used in space for deep space missions. It doesn't work in vacuum this same way since it needs a gaseous medium but for the deep space missions they carry their own gaseous medium with them, often xenon gas. It gives very little thrust but for a given mass of gas you can get enough and it doesn't use up much gas at a time so you can build up speed slowly. There is a some ongoing research by NASA and others.

30,000 can be gotten with a small Van de Graaff generator easily, but you also need the current, around 250 microamps, which a small Van de Graaff cannot supply (hmmm... I should try my big VDG). There are links in the description below this video to my webpages about making the higher current power supply I used in this video and also an old PC monitor one but the really old monitors are hard to find.

I guess toothpicks can be used if you can find some that are long enough. Or you can make a very small lifter. The first lifter I ever made was pretty small.

That's commonly known as a Variac, basically a variable transformer. I plug it into the wall socket so it gets 120 volts AC as input. I then plug something else into the Variac. As I turn the dial from 0 to maximum, whatever is plugged into it gets 0 volts AC up to 120 volts AC. In my case my I plug my 24 volt DC power supply into it. Giving my 24 VDC power supply an input voltage from 0 to 120 volts AC causes the power supply to output 0 to 24 volts DC. That feeds my high voltage power supply.

[@furulevi]

Is that high voltage pulsed at a certain frequency? (AC or DC?)

[@RimstarOrg]

It's flat DC. AC won't work. Some have used pulsed DC in the past but I've never tried.

[@RimstarOrg]

I haven't tried a circular shape but I've seen others who have. It works.

[@RimstarOrg]

Then you either build your own HV power supply from scratch (other link in the description) or buy one (I just added another link to the description.) You do need some current in order to ionize the air sufficiently for the required amount of ion wind so things like Wimshurst machines and Van de Graaff generators are usually not sufficient. However, I think I recall that the original lifter made by Transdimensional Technologies used a large VDG generator, a 1 foot dome (approximately).

[@RimstarOrg]

I haven't tried. But I've done the smoke test and there's plenty of air blowing down. Have a look at my video "Lifter Voltage/Current and Smoke/Airflow Test Measurements". There's a link to it in the description below this video.

Wood is an insulator. I've heard that it can be bad to use wood with high voltage but in all my years I've never found that to be the case. That includes with lifters. I've had plenty of arcs but they've never traveled along the wooden supports. Maybe if the wood's wet with tap water containing impurities, or something is coating the wood, or it's some sort of wood that has a lot of conductive material in it. Anyway, I'm glad you enjoy my videos, and thanks for watching!

Well, I guess I'm not sure it's ozone since I have no reference. But there's a very distinct smell when I heavily ionize air in these types of experiments and so I've just always said it's ozone. A lot of people do the same. Maybe it's not the ozone that's stimulating the nasal senses, but maybe if whatever it is is present then we can assume there's ozone too. It's a fact that this type of ionization produces ozone. Either way, it's good that there's a smell to remind people to ventilate.
