[@robertlapointe4093]

Hi Jay, nice video. A few thoughts on the "humidity problem". Humidity effects high voltage devices by adsorbing to the surfaces of solids, such as the materials of construction and dust particles in the air. Water adsorbed on surfaces reduces the surface resistance by providing a more conductive layer. This could be mitigated by using materials of construction with less affinity for water. PLA, Nylon, PVC, acrylic, PET and many others adsorb quite a bit of water. Better materials from this perspective would be polycarbonate, polystyrene, polyolefins (such as ultra high molecular weight polyethylene or polypropylene), Teflon and silicone rubber. Also, it might be interesting to try using a super-hydrophobic coating on the more problematic materials. This still leaves the problem of water adsorption on dust particles, which tend to clump together under humid conditions (the adsorbed water provides a sticky coating) forming small conductive clumps, which act as corona points in an electric field, reducing the breakdown voltage. One way around this problem is to choose dry, low particulate pollution (dust, pollen, soot, etc.) days for testing. Probably the worst environments for ionic thrusters would be in the vicinity of sea spray, or at higher altitude (where reduced air pressure will increase the conductivity of the air itself by increasing the mean-free-path for impact ionization). These problems could be mitigated by increasing the electrode distances in the thruster, but probably with a reduction in efficiency. Looking forward to see how you tackle these issues.

[@maxluthor6800]

what about simply putting an air filter +dehumidifier in front of the thrust inlet? we do that in our cars already. We cool the air.

[@hyakinthos_0902]

commenting so that this comment gets bumped

[@rbtgmnstcs]

One, maybe possible, solution I was thinking about, was if the incoming air, before the thruster, went through a flat section, between two charged plates, formed like a flat trumpet/horn. Then it might be possible to divert the particles in the air to either of the plates. If the intake side of the thruster would be pinched and placed close to the "mouth of the trumpet", then some of the air (hopefully containing more "unwanted stuff") would more likely pass outside of the pinched intake than going through the thruster. Basically an electrostaticly charged particle diverter. I haven't thought about it, but could the thruster have a flat shape, or would it become less efficient? If not, I guess the diverter would cause less drop in efficiency.

[@conorstewart2214]

A hydrophobic coating is probably the easiest option. Polycarbonate isn’t the easiest to print and polypropylene can be very difficult at times. Maybe trying resin prints would be an easier option?

[@brsrc759]

Dang bro you sound like a rocket scientist 😂

[@RimstarOrg]

Nice work! Since you're not working with aluminum foil, it may not be so noticeable but each spark makes a tiny hole in your smooth electrode, making it less smooth and possibly more likely to spark. You could try replacing the electrode if you had a lot of sparking to see if it gets better.

I have a bit of experience with 3d prints and high voltage from my previous job. One thing we discovered was that directionality of the print matters; very high voltage had a tendency to pass clean through the layer lines, sometimes creating little carbon trails and making them a better conductor than a pure air gap. You may be able to reduce sparking by making the rings a nested two-part design, with the nesting parts printed 90 degrees from each other (though that might require a more support material than is practical). You could also try printing with a material you can glaze (e.g. ABS + acetone spray, though this is a huge pain to work with), or experiment with various coatings (maybe a thinned rubber sealant).

[@PlasmaChannel]

Thanks for this input, its very good to know. Yeah, I luckily have not had issues with the voltage jumping through, as long as I keep all edges rounded on the ground.

[@iczer01]

Did you ever test using sla or Msla vs fdm I could see how the exotic resins and high resolution of sla could be a way to avoid your findings

[@ntorix599]

I think having the thrusters rotate would be a huge improvement. You could use the force of trusters combined with the counter force of the water to make a higher net force forward like a sail boat. That would be pretty complicated though so maybe just turning the thrusters to simulate the forces on a boat from sails and adding a rudder for steering. You'd probably need to add some plastic under the hauls to increase side ways friction.

[@robvod]

would a spiral shape help with density of the thruster. As I understand electrical charge is fired from the positive -> negative terminal, hitting air molecules that then creates thrust. By using a spiral-shaped postive terminal + spiral-shaped negative terminal to match, the density of electrons flying across would be much increased (potentially). It could even be set up to be a spiral along the z-axis as well. A bit more complex to build but if done incrementally, it may improve the thrust? Also could all the sparks be re-routed to another circuit/ground?

[@broodaiamdewey622]

​@@robvodI've seen other creators using straight surfaces with serrated edges. Maybe they're using the tips to concentrate that flow like a bunch of mini nozzles.

[@roelieboy204]

If you would put the thrusters on a 360° rotating servo, you could steer with both engines active, thus having more power while steering. It can also be used as a reverse by rotating the servo's 180° This could be a nice addition.

Love watching the ion engine evolve. I used to work with electrostatics when I was an engineer at a laser printer company. One of the things that I first found surprising, but then obvious after some thought was how much the environment played a role in getting toner on paper. Humidity, temperature, and altitude all made a considerable impact. Enough so that even your average printer has sensors inside the case to keep track of those variables to adjust the xerographics every time you press print.

10:38 That looks like adding a significant weight to the catamaran. I would opt for something 3D printed and super minimalist light weight. Same with the hull which seems larger and deeper than it needs to be, thus adding unnecessary weight. This extra weight would slow down the pickup speed of the boat.

[@kendric5578]

First, this is super cool. I can't wait to see larger scale models. A question about it being 'silent'. Have you checked this with an oscilloscope or something similar?

For your engines, I would suggest making jet panels for air concentration, like jet planes have. Where the exhaust diameter is reduced for more thrust. In terms of humidity, all you have to do is make air filters in front of the engine out of some kind of woven mesh so that you don't kill more insects.

[@BootlegHuman]

Would be curious to see the comparison of this versus a catamaran using two piezoelectric fans in terms of noise, power and turning

[@billyheng4824]

Electrical interference can be caused by other electronic devices, such as power lines or radios. To overcome these problems, you can try the following: Use a dehumidifier: A dehumidifier can help to reduce the humidity in the air, which can help to reduce electrical noise. Isolate the ion engine from vibration: You can try to isolate the ion engine from vibration by mounting it on a vibration-resistant platform. Use shielded cables: Shielded cables can help to protect the ion engine from electrical interference. Use a noise filter: A noise filter can help to reduce electrical noise. It is also important to make sure that the ion engine is properly grounded. This will help to prevent electrical noise from entering the ion engine

Then modulate a sound source thru the high voltage source. The salt ions are what vibrate to make the sound.

I have an idea: Widen the gaps so that the boat takes advantage of the humidity to function. You've got a design optimized for low-humidity air, now you just need to modify it to be optimized for high-humidity air.

[@marcods6546]

I like this idea. My alternative approach would be to install a heater in front of the ion thrusters (literally just some hot wires) that would evaporate the water droplets before entering the ion thruster. But if your idea works, it sounds way more economical!

[@TwinShards]

I like this idea too. This wouldn't be possible as fix 3D printed parts alone but i bet someone could come up with a design that can make tighter or larger gap based of a humidity sensor. The lower the humidity, the closer the components are together. The higher the humidity the larger the gap become.

[@malcomreynolds4103]

that reduces the thrust

[@callmeyang]

Here are some ideas: . Isolate the thruster from humidity. . use existing airflow against a sail or wing . Point thruster other directions, including a sail . Hydrofoil the cat once any of this is working. . Use solar or metal/rust air battery or something similar to deliver power to thrusters without having to charge

The problem isn't droplets, it's that humid air arcs at a lower voltage than non-humid air.

[@Franckie.G]

Incredible project! The concept of using ionic thrust to power a boat is truly groundbreaking and has the potential to revolutionize marine transportation. The silent operation and zero-emission nature of this technology are particularly impressive. However, as with any pioneering technology, there’s always room for improvement. Here are a few suggestions: .1 Humidity Resistance: The thrusters’ performance was significantly affected by humidity. To combat this, consider using a hydrophobic coating such as a nano-coating spray on the thruster components. Also, consider integrating a small Peltier dehumidifier system within the thruster assembly. These are compact, lightweight, and can effectively reduce the humidity in enclosed spaces. You could also design a 3D printed casing for the thrusters using a water-resistant material like PETG, which could include a small compartment for silica gel packets to absorb moisture. 2. Thrust Efficiency: To increase the thrust, consider using a high-frequency, high-voltage power supply. This could potentially generate more ions and thus increase thrust. You could also experiment with different electrode materials and designs. For instance, tungsten or graphite electrodes might provide better performance due to their high melting points and good electrical conductivity. Using a 3D printer, you could easily create electrodes with larger surface areas or unique shapes that might generate more ions. For instance, a comb-like structure could potentially increase the ion output. 3. Reverse Thrust Capability: To add reverse capability, consider designing a mechanical system that physically reverses the orientation of the thrusters. This could be achieved using a servo motor controlled by a microcontroller like an Arduino. You could 3D print the necessary mounts and linkages to connect the servo to the thrusters. Alternatively, you could use a Double Pole Double Throw (DPDT) switch to reverse the polarity of the voltage applied to the thrusters, reversing the direction of the ion flow. 4. Renewable Energy Sources: To extend the boat’s operating time, consider incorporating a hybrid energy system combining solar panels and a small wind turbine. This would provide power in a wider range of conditions. You could 3D print a custom mount to securely attach the solar panels and the wind turbine to the boat. Also, consider using a more energy-dense battery technology, like lithium-polymer, to extend the operation time. 5. Safety Measures: For safety, consider using a fuse or a circuit breaker in your power supply circuit to prevent overcurrent situations. Also, consider using a Residual Current Device (RCD) or Ground Fault Circuit Interrupter (GFCI) to protect against electric shock. Consider 3D printing a well-insulated, waterproof housing for the high-voltage components. This would protect against both electric shock and water damage. Also, consider integrating a voltage indicator or a warning light that alerts when the system is powered on. 6. Hull Design: Consider using a hydrodynamic simulation software like OpenFOAM or CAESES to optimize the hull design. This could help reduce drag and increase stability. You could then use these optimized designs as a basis for your 3D printed hull. You could also experiment with adjustable hull features, like a retractable keel, to adapt to different water conditions. 7. Lightweight Materials: Consider using advanced composite materials like carbon fiber or Kevlar for the boat’s construction. These materials are lightweight yet extremely strong and durable. They can be molded into complex shapes, making them suitable for both the hull and the thrusters. For parts that can be 3D printed, consider using lightweight but strong materials like PLA+ or PETG. For parts requiring extra strength, consider using a carbon fiber-infused filament. 8. Modular Design: Consider designing the boat in a modular way, where components like the thrusters, power supply, and control systems can be easily replaced or upgraded. This would allow for easier maintenance and the ability to upgrade the boat as technology advances. You could 3D print custom mounts and brackets to make the components easily removable. Your passion is truly inspiring, and I can’t wait to see how this project evolves.

[@Iridiumalchemist]

I think that could dramatically improve this project by optimizing things like thrust to power input. If the accounting you gave around 7:45 is correct, full power delivers only marginal improvements in thrust. There is likely an optimal wattage and voltage and laying out the thrust curve for this device would be an interesting video in and of itself. In addition, other improvements like nozzling airflow towards the output will give you better directed thrust. Having several small optimized ion thrusters will produce significantly better results that having one large unoptimized thruster. Additionally, it will allow you to control directionality without the addition of moving parts by reducing thrust to a particular thruster.

[@dangerousfables]

I was thinking about putting glitter on it.

[@Soheil-ev6ls]

As a side note, diminished airspeed on higher power input is expected, due to kinetic energy following a curve. So yes, slower is more efficient.

[@Wolforce]

I imagine the humidity changes the conductivity of the air? Maybe start with variable distance grids and with time you could automate them depending of the current humidy ( I'm guessing more humidity = more conductivity = bigger distance between the thruster grids) What a journey it has been already though, amazing videos

[@GlennHamblin]

Some early humidity sensors used a strand of hair or fiber under slight tension that stretched when they absorbed moisture and shrank when they dried. Perhaps something based on this idea could automatically adjust filament spacing in the engines?

[@RichardBetel]

Electrostatic discharge machining uses sparks to cut steel. Those systems monitor current to manage spark gap width. I think that would work more generally: other factors like temperature, air pressure, and voltage would already be accounted for if you aim for constant current. If you start with humidity, you’d need a bunch of other sensors and correction factors.

This might be why some UFOs are reported making their own mist or gas around their hulls. If they fly via ionization, it could explain why some look like solid ovals or saucers of light.

[@alderin1]

When I was experimenting with ionic lifters back in the late 1990's, the method to reduce arcing due to humidity was to separate the fields more.

I'm envisioning a scissor-lift style arrangement that keeps proportions but only needs one actuator. Otherwise, great work! Hope this helps!

If you can eventually get enough thrust then look into adding hydrofoils to your catamaran.

First a ducted fan to get you out of the water then switch to the ion thruster.

Quick suggestion! Don't use a ducted design, you might be loosing airflow that way. I'd suggest using a fuselage, and treat it like a solid state jet engine(my dads words on this), with a place to compress the airflow to increase the speed and all

[@glonkfpv]

It might not have enough static pressure to be able to push air through a restriction like a nozzle.

[@KingBobXVI]

@@glonkfpv - I believe you're correct; watch the original video on the ionic thruster, the first version didn't have ducts and just resulted in pressure loss.

[@glonkfpv]

@KingBobXIV exactly my point it would be like putting a nozzle on an edf jet. you can't just make more thrust with an edf or an ionic thruster by restricting the flow like you can a rocket or a turbine

[@prototypedrakon9899]

@glonkFPV true, leaving the nozzle put would work better, but the ducted design here leaves too many holes and is losing airspeed

[@karatos]

@@prototypedrakon9899 No, it is gaining net thrust. The ion jet makes a stream of low pressure which brings air in from around it to provide the majority of the thrust. If you don't let air in then you don't get that thrust. The structure provides containment and direction to try to keep existing flow but choking it off leaves only the very little movement of the air from the mouth of the system.

[@AerialWaviator]

Great work Jay, EPIC results! Since you and Daniel are so good on the collaboration thing, suggest you two make an ionic airship. Maybe the folks at Climate Plage Arena would let you do some indoor testing. Just use helium, not hydrogen. ;) If all goes well testing, could fly it around the Space Needle!

[@parsonsenergy]

Good idea but hydrogen under modest pressure is not an explosive issue… as long as the pressure is above atmospheric.. it can also act as a reservoir to pass through a fuel cell to power the electrostatic thrusters…

[@k-boi-501]

that diesel boat and airboat had such a sexy sound! the airboat sounded better than most cars out there!!

[@Nerdiasme]

Finally someone who sees noise pollution as a problem ! 👍

[@simonhall886]

I wonder what the difference in performance if there were more modules making the drive longer.I also wonder what the effect of making them thinner. A bit of inspiration from Star Trek Enterprise 😁

[@smartcarfor2]

The sound of zaps was kind of cool! Can’t wait to see how this goes as it gets scaled up!

[@georgemathieson6097]

Just wanna say, you're a LOT more genuine these days - it's great to see!

[@milespeterson5049]

The Next step would be to make an Ionic Thrust Drone, completely noiseless, very cool and I would love to see that in the future.

[@aripenumbra]

You are the real iron man we needed in life. So flippin cool

[@andymuzzo8568]

Awesome. Great idea for this collaboration. And what an awesome build.

[@altus1226]

For your next version, I want you to consider a series of stationary baffled blades with the electrodes at positions to feed air in shapes resembling an air foil. You should look to Jet engine design for this, their internal series of fans are excellent at compressing air (somewhat) uniformly and using it for propulsive thrust. You just want your blades to be static, with a later revision perhaps having variably pitching blades to adapt to air pressure conditions. I suspect you'll want the blades to be really low angle of attack though. But that is just my mental guesstimate, higher could well be moar better. Or the whole thing bunk /shrug Also make a series of spots for particles to be deflected from the air-path vortexes. To this end, look up Cyclone Dust Collectors

[@anonymously4U]

Good thinking

[@PaulTTN]

Thanks!

[@snuselus9143]

16:27 Those with good ears hearing this high pitch noise knows all the dogs be freaking out to shit sound

[@MrSpinmeout88]

Just a thought. Have you tried testing your air velocity with a nozzle restriction to see if you can find a happy medium between thrust performance and airflow restriction? Love the concept, don't love the arcing going on around water, bit too scary. Have fun!

[@billyheng4824]

increasing the size of the input could help to optimize the thruster. This would allow the catamaran to inhale more air, which would then be expelled out the back, creating thrust. This could potentially increase the speed of the catamaran.hope to see this in you next version being implement GOOD LUCK !!!

[@Naughtius_Maximus]

You should try metering in helium through manifolds placed at intake plates and checking those airflow speed tests again . Also I'm curious if modulating the plates output from first to last would yield gains . Great work !

[@Streamcatcher]

Exactly, I am wondering about this to. As varying the size and shapes of each stage. To compress the airflow sort of like in an jet engine. I am wildly aiming at the therm "electrostatic vortex air compression". 😍

[@Naughtius_Maximus]

@@Streamcatcher You got me thinking that super cooling helium would aid in compression by lowering intake air temperature and creating even more expansion when ionized. I like how you think

[@nbrpwng]

Maybe you could add some magnetohydrodyamic (MHD) thrusters underwater too, as another electric propulsion option? That wouldn't suffer from humidity, and maybe there's some advantages to using either one in certain situations?

[@lissaxitray8110]

The most unbelievable part is how that goose didn't immediately hiss and charge at you.

[@pokulan]

You should implement somehow a way to increase the distance between the electrodes depending on humidity :) Maybe a telescopic design with servos?

[@pattheplanter]

I assumed the humidity would actually help with the ionisation, if you can adapt the gap for optimal thrust.

[@olddog2newtricks]

I have a thought. What if each stage of the thruster got smaller? Each stage is trying to accelerate air that is moving faster than the stage before so if the size reduced then you might get a bit of a venturi effect, increasing air speed.

[@trirunner2520]

I had the exact same idea. If each section started at the size of the previous and slightly reduced down until the final section and have it a bit longer and more focused. Of course this works with a standard motorized fan, but not sure if it would hold true for ionic wind. I would think so.

[@aaronhighfill2959]

The humidity will even effect inboard boats- I took a fishing trip in the gulf and it took almost half an hour for the condensation to evaporate off the pulleys so that the captan could go full throttle bc other wise it would just squeal, I also think Onshape is a great tool for people who want to create free models

[@ObviousSchism]

Noise pollution is vastly underrated.

[@AllBeingsAreLoveAmen]

Seems like you should make it waterproof and reduce sparking noise. If only it went faster. Cool build.

[@Saporling]

Whenever you drop a new ion video I just wanna watch it, love that it goes into something practical as well. Maybe worth just controlling the steering with a rudder and just let the thrusters deal with the speed?

[@gp5313]

Can't wait to see this masterpeace in the acual big scale!

[@andreydanilchuk8343]

It's work. It's much important for high speed. Very nice idea 👍

[@xomvoid_akaluchiru_987]

So a huge advantage of ionic thrust is how little noise it makes, but what about an electric powered toroidal propeller? Research in that direction is also cutting edge, from what I know, and maybe it could get even quieter. I'm just taking a guess using my limited knowledge, but isn't ionic thrust really inefficient? It seems like you'd get more power using an electric motor. So what other advantages of ionic thrust am I missing? I'm really curious!

[@wizardozark2735]

Another way you could test it is with a plane ballast with helium, shaped like something from a popular sci Fi show. The options are a little limited but something like an x-wing would work well, just lighten it with helium filled in the center, maybe a balloon or two tied to it as well, not sure how the weight would play out but essentially get it neutral to ground level and test how they would work in a slightly more finalized manor like if they were installed into something marketable, what would that look like housing wise, and how much would it hinder flight? I'm saying sci Fi nods/reference just for the showmanship aspect. Also because you know when it's successful you'll want to display it and bonus points when it nods to something that inspired you. Also how can you not when developing ionic thrusters? 😂 But hey this is an amazing build, I am so impressed with your work. Definitely call this a win for science.😊

[@DM-wp9vq]

They could use a sailboat. Solved for that type of research. I used to sail with a couple of friends and one of my friend's boat, a nice 26 footer. They're very maneuverable, and silent. Plus they're incredibly easy to use. Sailing isn't hard, at all. Just pick a day with a good breeze, and go study whales until tech reaches a viable solution for commerce, recreation, and research. In other words, simplifying and upscaling Ion Drive tech or figuring out another as for now unknown method of propulsion. Great videos as always sir! I love how chill they are and how informative you make them. You're a knowledgeable dude for sure!

[@TrailBlazers757]

How would you waterproof the thrusters , flip it upside down , and use the water for coolant? Oh and make them bigger!

[@SVPearler]

As a sail boat owner, humidity/water will be a big issue. Even on nice days, water mist goes over the boat. My cockpit screen is well over 2m from the water and to the rear of the boat, and it gets water on it. This is the small droplets from the spray the hulls create. My boat is 43ft long. Can a TIE create lots of horsepower. My Catamaran is quite light for its 43ft. Two 20hp engines propel it at 9 knots full throttle. They also dont take up much space. Maybe this system could be an assist system, like sail assist on some container ships. Just got to figure a way to insulate it from rain, sea spray, fog, humidity!

[@brianevans6423]

Brother you deserve 10 million subs, just found your channel and I am completely enthralled by the science here!! You're gonna change the world one day dude.

[@PlasmaChannel]

Thank you, that means a lot. I’m honored you’re part of the plasma Fam.

[@sergeys.8830]

Great attempt and video! Looking forward for the version next. I am becoming a fan of the electric propulsion systems

[@donaldblankenship8057]

The arcing is very good for propulsion if it is conserved with ducting. It provides thousands of degrees of heat breaking down h2o as a hi-T nonflamable propellant. In a light-weight design, it could propel full-scale aircraft of any size.

[@dennissorensen8765]

You could revolutionize the Arctic dog-sled business! Solar panel roof, treadmill for emergency charging, 4 skates on the sides to lower for when on pure ice, effectively making it an ice racer without a sail. I mean... hot damn! 😅🤓🙈

[@Nau-Tec]

Well done project! Would be curious to see how the propulsion would be affected if the air stream of the ion engines would directly guided in to the water. Converting the system basically to a water jet motor.

[@CrazyFunnyCats]

9 mosquitos 🦟 died making this video 😂 Awesome vid dudes 👍☕️☕️☕️

[@joshuadaugherty5642]

A&P here. I keep looking at this from your inlet speed revelation and - with this having a very similar design to multistage, axial flow, turbine engine - i had a few ideas that might help multiply thrust per stage through aero manipulation. These ideas might be some of the ideas you tried and didn’t work, just thought I’d throw out the idea or two. You have to use bypass to make the multistage work. I feel like the middle of your grids aren’t helping with thrust past the first stage. I wondered about a radial grid design where the bars are perpendicular to the radius, with an inner airfoil for a support ring. The outer ring would become a one piece, high bypass duct, with a reverse Venturi shape to help slow the bypass air down and achieve maximum acceleration per stage. Have a convergent duct after the final stage to convert the increased pressure to velocity. I’ve got ideas to fine tune but I’ve already written a novel 😂 love the channel keep up the awesome work!
