Designing a Futuristic Magnetic Turbine (MHD drive)

oh that's just next level the volume of this is crazy a few months ago i started researching mhd units or magneto hydrodynamic thrust it's a super exotic type of thrust that uses no moving parts and is straight out of science fiction, better yet, produce it. Incredibly easy, as many videos on YouTube show, all you need is two electrodes, a magnet and some salt water plus electricity. For the sake of categories, I call these one-dimensional thrusters, so after physically testing numerous variables, I designed what I consider a two-dimensional thruster. some potential with speeds above 35cm per second, like many early prototypes, the design looked promising, but had plenty of room for improvement, from the magnets and electrodes to the geometry and repairability.

Everything could be better after a considerable redesign. Printing and proofs. I found a solution in the form of what I like to call a three dimensional brm thruster, this video is sponsored by novium. Okay, so the mhd Thrust can be used to move water plasma or any conductive fluid. However, now what interests me most is its use for maritime transport. We've had propellers since the beginning of time, so what's the point? Both gasoline-powered boats and diesel boats emit enormous amounts of noise pollution into the ocean, which can have detrimental effects on marine life. They don't like that as long as they aren't.

Perfect mhd units can offer a quieter alternative. They also have no moving parts, which is great. Check out my first mhd thruster. To start, a few design improvements come to mind. These magnets are metallic, which means they conduct electricity. Submerged underwater they act as a kind of partial short circuit between the electrodes, stealing energy from the system. This isn't completely submerged, but you get the idea: the

magnetic

fields at the top and bottom are completely exposed. This is a great inefficiency. because while the main outlet goes backwards, this exposure causes a countercurrent to flow forward. The nozzle I designed is too narrow, it slows down the output.

The electrodes corrode easily and lastly, the magnets I used are not the strongest grade of neodymium. Easy to repair. Assembly was also high on my list, so after many hours staring into space, I realized that a radial design might be the way to go, so I got to work

designing

a booster that would solve all these problems looking for magnets similar in dimensions to the ones Last time I used a little deeper and found identical sizes but stronger on the pole, while the old ones were n42, these were n45. I ordered 16 and cried silently. Then I went to onlinemetals.com and looked for an external electrode and an internal electrode.

Made of 316 stainless steel with ordered supplies. I sat down for a super intensive 3D modeling session after 2 days. I arrived at the design that held magnets between two radially shaped circular electrodes. The magnets could be waterproofed and then slid into these separate compartments with the The hardest part behind me I pressed print and prepared myself for an incredible wait. Removing the supports from this print was as fun as a first date. You know what I'm talking about. I love how it turned out, although soon after my two stainless steel. Steel tubes arrived, as well as the most

magnetic

box in the world containing my 16 neodymium magnets, absolute powers of strength.

Turns out these tubes were not cut to spec, so a quick sanding solution to ensure these magnets don't conduct electricity while I'm underwater. I arranged them individually a bit like a ceremonial sacrifice and gave them a flexible re-treatment, that's a lot of damage after they dried. I had everything I needed to assemble the Thruster. The beauty of this design lies in how simple it is to assemble or disassemble. For repairs, the inner electrode slides into place as does the outer electrode. It's that simple, it looks great, let's try it before the initial tests. This was the intention behind my design.

The inner tube is the positive electrode and the outer tube is the negative, so that the electric field. It will radiate outward from the center, all the magnets are placed to produce a magnetic field perpendicular to this electric field and the entire magnetic field is being used, we will see if it works as intended. I didn't do many calculations. I just went off the principles. I learned about the first Thruster after printing a custom mount and mixing about 15 gallons of salt water. It was good, let's start with 10 volts. Out of curiosity, yes it works, it's quite slow, but it works.

I repeated the test three times and found an average speed of 17 cm per second, this is 15 volts, yes, yes, faster speed, cool, wow, with another triplicate test, the average speed was now 20 cm per second, let's get to 20 volts and oh look at that water column, you can definitely see that column. of water moving at an even faster speed this time the average output was 28.5 per second and 25 volts Ah, that's a massive increase in output, definitely the fastest output yet, but still not as fast as I would like and with the final test speed in triplicate. It averaged 37 CM per second, as you can clearly see, this is a positive correlation, the thruster clearly worked, although not as well as I would have expected, so after thinking a little more I realized that this design already had room for improvement. improvement, i.e. the hydrodynamics, the front and rear are simply flat, this slows down the entry of water and produces eddy currents behind the supports visible here, which increases the resistance, so I sat down for an intense redesign of this propellant using the form to start.

I added an end cone to decrease drag at the exit as well as a removable center insert, then I turned it around and molded a hydrodynamic front end. This is the design program I've used for all of my 3D printing projects because it's really simple and designed to be used by almost anyone I've grown up with. I really like it and I'll leave a link in the description below so you can try it for free by photographing the design on my Prussa. He got to work and brought this final design to life. Well, it will be printed forever like all the others.

Only one of these attempts took now. If you've been following my channel for a while, you may have noticed that my builds tend to be very clean and precise because, frankly, I prefer a product that looks completely fine, so here's why. Video Sponsor I have partnered with novium, they create unique and innovative high-end products, such as their levitating floating pens, with the goal of inspiring creativity and curiosity, not unlike the goal of my channel, so this guy is your pen floating interstellar, it is an inspired space. The design tilts at 23.5° as a tribute to the Earth's axis and comes with the option of embedding a piece of meteorite into the handle.

I love meteorites and I have a huge collection which is great. It also comes in various colors, such as magma from Mars and Neptune. Blue and 18K gold plated, they also have their future Edition floating pen, which is a 2-in-one SL fountain pen that tilts almost sideways. These things are the perfect combination of art and space and to be honest, they make for some amazing writing. drawing experience, so it's no surprise that they won Time Magazine's award for best inventions in 2022. This makes them an amazing gift for anyone who loves science. You can find them at novium design.com and I'll leave links in the description below.

Oh, it took me a staggering 51 hours to print, but the results were worth the wait after punching a few. The locating holes in the inner tube, each of the 12 magnets, slid into place, then the outer shell and inner shell that screwed the tubes into place provided stability, but also an electrical connection for the positive, for height. I inserted the exhaust which blocks the well The rebuild is complete and a lot of work went into this so let's give it some power and see what it's capable of.

Here goes 15 volts, oh oh, that's definitely better, it's much better, while this view is great for measuring speed and the final view provides an incredible window into electrolyte gas production and it's crazy how fast it happens in speed wise this redesign now pushes 28 CM per second here's 25 oh which is just the next level the volume on this is crazy adding D to the input really helped visualize the flow On this thruster you can clearly see that the inlet is laminar and the outlet turbulent, which is really cool and it's pretty clear that the added end cones were doing their job of focusing the thrust.

Allin with 25 volts in this redesign the speed now averaged 47 CM per second, that's a problem, so the radial topography used here clearly shows some promise. I'm very excited about it. I'm also pretty happy with the results. Let's compare this design with its predecessor. The first design produced an exhaust velocity of 35 cm per second, resulting in With a flow rate of 250 m/second and requiring 12 s at 25 volts, the brm Thruster produced an exhaust velocity close to 50 cm/second, which resulted in a flow rate of 3650 m/second and requiring 30 amperes at 25 volts. Different performances, but depend on identical science, essentially, this thruster is a solid-state

turbine

that is based on the principles of magneto hydrodynamic thrust, which is a type of thrust that does not use moving parts but is based on sibling rivalry. , so to speak, between magnetic fields and electric fields.

I mentioned this relationship in my first Marine Thruster video when a magnetic field interacts with an electric field that is oriented perpendicularly the electric charge carriers experience a force in the Z direction which is called the Loren force and in this case what are they? the charge carriers of electrified water? Remember that this design creates a perpendicular alignment between the electric and magnetic fields in terms of the material. I chose 316 stainless steel tubes because they are super corrosion resistant, but they will eventually corrode due to electrolysis, so repairing the impeller is as easy as sliding. tube and replace it with a new one.

While this propeller may not have comparable power to a propeller, it has the advantage of being quieter to operate both above and below water and does not involve moving parts. You know it might be interesting to build a boat using these propellers, let me know your thoughts in the comments below and don't forget to subscribe to see what I'll be working on over the years.
