Thank you for teaching this old man something new every time I watch one of your videos! You have taught me on a daily basis. You are a fantastic teacher. Please keep it up if you can. The Magneto hydrodynamic drive episode was great!
I love how The Action Lab does a great job of showing all these arcane wonders unknown to laypeople, and we get his mild bemusement when it works. "Whoa, look how fast it's flowing!" he says, after demonstrating something that looks like pure science fiction.

I love watching and better understanding these concepts the way you explain and actually show us things through experiment and your genuine love for this shows and helps with the teaching/learning aspect!
does the opposite happen ? if you flow an ionic fluid flow through a channel connected with wire, does it produce a current ? I guess a potential application would be sea water power generator that use generate power when the tide rise and fall. Since there is no moving part, you don't need worry about rust or other mechanical failure form the harsh sea environment
Wondering the same thing here!

This is one of your best informatives videos like magneto levitation, Which was something new for me to learn.
Check out acoustic levitation

Sees title: Magnetodhydad... what?

This was one of my absolute favorites! Go get a Nobel Prize or something dang!
thx for experiment. I see great use of this effect in simple rust removal process with electrolysis. You actually get water to flow, what seems useful, maybe.
You are so amazingly sychronous! I just finished prototyping an MHD vacuum pump. I needed a backing pump to clear out remaining gases in a high vacuum. Ion pumps ignore some gases and turbomolecular pumps are too expensive and high maintenance. The ancient Sprengel mercury pump was suitable but too tall, too fragile and too slow. I realized all I needed was a liquid metal slug passing the same Y junction repeatedly as fast as possible. I made a flat circular MHD ring track to pump two molten eutectic alloy slugs around a small loop at high speed. Had to place a small reservior and drop gate between inlet and outlet ports to prevent gas from bypassing the slugs. As one slug plows into the reservoir it triggers a launch circuit to eject a drop from the other side of the reservior which then plows gas ahead of it around to the outlet stem again. It runs like a bat out of hell because it is only turned on once the roughing pump takes things down to 10 microns. And since the alloy is eutectic it's vapor pressure is worlds below that of the mercury originally used for this purpose. I am still working on the final build since it has been a nightmare designing the parts and materials to eliminate all the absorbed gases and keep the droplet from jetting out it's middle while the rest remained behind on the track walls to break up and break electrical contact. I actually made opposing magnets move the drop through the charged channel. This makes the drop force itself together from opposite directions to stop it from breaking up. The external moving magnets then shuffle the drops around the track. Still needs refinements. I am still getting a few X-rays from electrons hitting remnant gas in my DIY X-ray tube.
are you making a spacecraft engine?
I just think you are awesome, such a nice, positive person who really has a passion and does a great job sharing it. Love watching your videos, also do you have a patron or some kind of funding?
*Well, my friend, i really thank you for making my lockdown* 😉😊😌

Wow ! Truly awesome !! I can see the warp drive is moving in that way .
What if you could collect the hydrogen bubbles and run them back through a fuel cell that creates the energy to propel it.
That's actually a pretty good idea. That might be able to get some of that lost efficiency back
or even ignite the hydrogen for extra thrust!
Would be a great idea for a submarine or a boat, submarines have massive reactors though so I don't really think its needed... it seems they could use this for stealth technology for submarines
To create hydrogen fuel is very costly, to run a car for 1km with hydrogen fuel but in the process it need to burn 4x fossil fuel for that hydrogen. Btw hydrogen car is electric car, that hydrogen cannot be burned to move your car like gasoline, so another energy loss to convert hydrogen to electric
@@CahyoPrabowo you definitely can burn hydrogen in a combustion engine..
People do it all the time.
I've seen where people do gain some efficiency, especially if they can reprogram the ECU to compensate for the extra oxygen(unmodified the car will sense extra oxygen from hho, and it will dump more gas in to compensate)
Hydrogen has a very high octane, and it also has a better rate of expansion... so this means it can help gas engines run better by burning more gas closer to the cylinder wall that would otherwise go unburned. It also helps remove engine deposits by turning to steam after combustion, which also helps lower nox emissions and cool the exhaust..
There are some methods that are more efficient then others, and I believe people need to experiment more.
The fact im an idiot and don't understand anything, but I still watch this type of videos shows that even idiots can watch videos

Learning about this is actually a gamechanger for the sci-fi I'm writing about a futuristic post-post apocalypse society (meaning there *was* an apocalypse, but things recovered now) that commonly employs boat transit to get around (due to both cultural/historical reasons and their reality's Earth having higher sea levels)
They also strive to be eco-friendly, so this also being a clean propulsion method (assuming the power plant the energy came from is also clean) is huge.
The efficiency problem of course exists, but I figure that would improve dramatically because this fictional society has room-temp superconductors and nanites.
Jean-pierre petit from CNRS discovered this very long time ago, that's great that young scientist like you is studying this and show that it is working! thanks for your share...
wait until this concept is utilized with supercavitation.
Love this channel, cheers from Argentina

Great demo! So simple.
Wow, this is amazing and fascinating! Really neat! 👍🏻😀
If you increase the voltage to over 10 kV or 20 kV (I used maybe 30-50 kV) you can use deionized water and probably get more propulsion. (Hardly any electrolysis happens.)
Each and every time ! , This guy amazes us 👍❤️, love from india bro
The ideas this inspires for me makes this very interesting.
Fascinating stuff. Thanks!
Good Bad or Ugly, I've been waiting years for someone to demonstrate an inductive based MHD vs the many conductive based MHD.
one might google: Pulsed Induction thruster.
I think you may be able to get more out of it if you increased the plates. If it's anything like electrolysis, anything over 2v between plates is overvoltage and results in steam. If you're using a nine volt battery try putting three or four plates between the cathode and anode. Count the spaces as 2v each. Just a thought. Now you got me wondering. Gotta build one. LOL.
Magneto- with the “e” separated from the next vowel, the “o”, by only one consonant, the “t”, it should be pronounced as “magneeto”.
Should have mentioned the full scale test ship that was built. It used enormous diesel generator sets for power, and did not move very fast. And then of course there was the Red October!
Very nice demo and description. Have always been fascinated with the concept. Too bad our seas are not mercury. ;)

You can do the same with non-conductive liquids too. It works with oil, and you can do it without the use of a magnet. Because oil is an insulator, you need to use the electric field instead - hence why you need a very high voltage.
can you please explain why is it moving?
Just thought that I can't be surprised to the bottom of my heart with a simple physical experiment. This channel keeps prove me wrong.
Great concept demonstration. These are the seeds of knowledge that planted in young minds will lead to amazing things. I always wondered how that sub in Red October actually worked in principle. Thank you for the explanation.

I never knew this really existed. This idea came to my mind and was thinking of testing it, but now am really amazed that it really works.
5:26 That's gotta be the best pirate I've ever seen.
Awesome video! Thank you!
Very interesting and important the experiments done here.
Hmm could it be possible to generate electricity by passing a ionised fluid through the same set-up but the electrodes are connected to a bulb or some load?
wow
There would be a loss so it would be easier and better to just connect it to you power supply
Probably, but you'd have to use more energy in the first place to set the fluid in motion
It is possible, but the power output is very low
It does have use though. The food industry often uses flow meters based on this principle to measure the flow of liquids without risking contamination
his students are the ones who are going to make the flying cars normal
Thank you
You managed to explain that in a way even I was able to understand
Was looking to understand how Magnetohydrodynamic drives work... thanks for your video :)

@@Think_Inc no prob with the title.
Really interesting, thank you!
Nice experiment ,now i can understand how magneto hydro dinamic work
So dumb question, but could this process be reversed to make an energy collection source in something like salt water?
Oddly enough, no.
@@mastermenthe saw a vid recently about a tesla turbine that utilized incredibly close plates and the viscosity of water to turn. Could be an interesting combination if this effect worked with the one in the vid (assuming it could work in reverse)
@@jacksonp12345 the key is that current must flow from electrode 1 into electrode 2, creating the electric field lines that intersect with the water to convert into motion. If you wanted to extract energy from the motion of water, you would need the water to somehow create its own electric field, or carry an electric field from another source, which would then ground itself into the electrodes.
If you attempted to run the drive in reverse like a normal motor generator, by forcing the flow of the water to travel in the opposite direction of the field lines, it would just act as a circuit resistor until it completely swamped the total current and voltage, shutting off the current flow entirely.
@@mastermenthe so I haven't looking heavily into the design of a tesla gen, but I'm assuming the plates rotate through a magnet or simply connect directly to a gen mechanically to make power yes? The main idea that prompted the combination suggestion is how the plates look alot like a capacitor and the salt water being the dielectric. Your 2nd paragraph sounds alot like a capacitor as well due to "saturation till no current flow" bit. Idea I'm more going for is trying to think of ways to increase tesla turbine efficiency, rather than making the concept in vid work perfectly.
It can be reversed, but it's even more inefficient. So far it only found its place in the food industry to measure the flow of liquids without having moving parts in the pipes and therefore not risking contamination
I read the title as, "I Made a Real Magneto... hydro... dynamico... Drive-o" XD

This is really informative.
This effect can be produced and with simple electric coil, considering a fact that water is paramagnetic. Set bunch of coils to form a tube, put on each coil one diode (to avoid tank circuit scenario) and start pumping dc in pulses. This is how caterpillar should work :)
This is what's powering the flying saucers people have been seeing for years. Ever wonder why they're always over the ocean? Also, 6:02. They can work over land
I'm always inspired by the videos you make

Great and simple way to harvest the magnetic force of magnets. Its already being used to propel boats with rotating magnets. Using the force to produce energy is the cleanest and most efficient way imo.
