Let's make a big one together.

Just a tip for your demonstrations, try adding fine mica powder to the water instead of ink. The mica shows flow and looks really cool, but most importantly it shows basically every detail of turbulence, flow and direction very clearly. (Think of those cool paint mixing videos with the insane swirls and colors.) and they come in basically any color and you only need to add it once and it will just continue to work without constantly adding dye or particulates. We used this technique in school when we learned about fluid dynamics and I use them all the time for resin work, so they’re readily available now because of the popularity of epoxy crafting.

My first thought..."one ping only" 😂 can't beat that caterpillar drive

from the data presented here, you can easily calculate the efficiency to be 0.12%. A ship propeller has a hydrodynamic efficiency of about 60%. That is a factor of 500. There is much more Energy in the electrolysis, and electrolysis is needed for the current.

I’d like to see a boat, but even more a comparison of efficiency between propellers and your drive.

That's awesome! Also I think you just gave me an idea

The lack of rotating components is actually a great feature of the turbine considering how damage prone a high speed propeller is to light impacts. This would also minimise marine wildlife incidents where props end up cutting and harming marine life. It also means that there would be significantly less maintenance and manufacturing requirement, and being sealed off as one part is a very good trait for something designed to be leakproof

Invented 1966 and tested with an submarine EMS-1 at the coast of California... Also Mitshubishi worked on it in the 1980-90s. They need about 4 Tesla to make it work. Probably does not work with sweet water rivers.

These would seem more interesting on a submarine rather than a boat especially since you could have them articulate in any direction for better 3d movement compared to a propellor

Oh man, a boat with these things would be awesome! Not sure if you meant toy/model boat or something bigger, but it'd be neat to see how many it takes to move a canoe or something small-but-mannable

I've had many sleepless nights with magnetohydrodynamic thrust.

Just came upon your channel and that was excellent. You put a lot of time, effort and funds into that thruster, and it exceeded expectations. I had to subscribe.

The one thing that i am not really sure about this idea is that you could actually see the dye shift colours (a possible indication of pH change as Sodium Hydroxide is being produced trough the electrolysis of salt water). Also, the chlorine produced gets bond to the sodium Hydroxide to make sodium chlorate. Not sure if alot of ships using this technology would produce significant amounts of either sodium Hydroxide or Sodium Chlorate thst could affect marine life. I mean sodium Hydroxide is corrosive to metal and skin

Have you considered electromagnets for this purpose? It would make it harder to repair since you now have a bunch of wires sticking through the outer casing but may provide a benefit in strength of the magnetic field and resultant thrust. Individual control of these could also possibly provide thrust vectoring without movement of the nozzles?

I pay for premium so I don't have ads and then they put them in the videos

Instead of measuring exhaust speed I would be interested in seeing it floated in the tank and static thrust measured with a scale, also static thrust per watt. I think this thing probably pulls an awful lot of power compared to a traditional prop judging by the fact that the cables caught fire.

Would love to see a scale replica of a cargo carrier vessel with a set of these and perhaps either azipod based or the through hull mounted thrusters some carriers use. Perhaps if there was a way to create a suitable powerbank in a water sealed environment? Would be super cool!

You are amazing!! I am very impressed. In my next life I hope to some of the things that you do. Look forward to see if a boat will move with your design.

Taking the time to explain your premise, testing, revisions, and processes brings us on the journey with you.
