self-powered magnetohydrodynamic motor

[MrJESUSGARCIA13]

Do you know of a possible way of making it spin faster?

[doctordavid22]

Hey, thanks. MHD makes sooooo much more sense now! I never looked at it from the chemical side, I was just focused on magnetic fields.

[tsbrownie]

So use gaseous electrodes that don't break down, stainless structure and use it for sewage treatment vats.

[DragonBoyGame]

Why does it turn this direction not the opposite?

[MucusFelidae]

Nice demo, like it for the surprise effect.

[lapmarty]

yes it is self power in the sens it is a battery

[johnshepherd2011]

how long will it continue to run before stopping?

[gilbondfac]

@johnshepherd2011 few hours...

[BuiltFarmStrong]

how did you build it

[Atomank68]

Surprisingly, the great Jules Verne described the exact same process in his great novels 20,000 LEAGUES UNDER THE SEA, and MASTER OF THE WORLD. The first using the salt waters of the ocean itself to act as the electrolyte to generate in magnetized electrodes in the Nautilus sub an electric current to generate electricity. In the latter case, he makes the argument that the magneized propellers of the "Arbatross" cut perpendicular to the Earth's manetic field to produce electricity and (Cont'd)

[Atomank68]

(Cont'd)...In the latter case, he makes the argument that the magnetized propellers of the "Arbotross" cut perpendicularly to the Earth's magnetic field to produce electricity and therefore self-propulsion. While the former example has been established over 150-years ago, the latter case may need verification. This is taking nothing away from Verne, who obviously studied the scientific papers of Faraday, Lorentnz, The great Nicolo Tesla, an others. Curious how this science has not advanced much!

[tehnookster]

@Atomank68 Tesla was a great great mind, halted because of the pursuit of money, who knows where he would have been with the proper funding. I believe electricity as we know it now was just the tip of the iceberg, energy is all around us, from sun, sea, wind, magnetism... crazy stuff.

[sloth7250]

isnt this just a battery with spinning electrodes? or an inside out homopolar? lol

[SirVladDracula]

How much torque would this motor kick out?

I realise that it's only a demonstration of principle; but if used as a mechanical device, how much torque could it really kick out?

[sloth7250]

@SirVladDracula not a whole lot, if any

[001110brad]

so...um...what would you hook it up to...a lamp or some thing it dont look like it would make much electricity. hell from here i could use my bike to make more electricity but....i dont use my bike :P

[hotondale]

now attach a motor and tada u have powerrr!!!! make a bigger ? ;)

[drakonian232]

gz man good mind

[ziziintube]

Why is it rotating?

[inventhead]

let me get a burger fry and a large orange drink!

[skunkape49]

ok have you tryed tapping power off the rotter and grounding to the fluid and check volts

[L571J]

So it's a battery propelled motor with a fancy name. I'm pretty sure that this type of thing has been around for a very long time. What, exactly, is the point of all this? Is it just to have fun and play around with magnets/electricity?

Lorentz forces, to my understand, are not what make an MHD motor. After all, those forces are all around us all the time. I thought to be an MHD it had to have no moving parts and it had to the be the water moving. I can't tell, is the water moving?

[Thepoliticman]

@L571J Ummm... it SELF POWERS?? thats not normal....

[L571J]

@Thepoliticman It's just a battery. The guy is calling it "self-powered," but it is using the current created from the electrodes that are slowing being broken down in the sulfuric acid. This creates and electric current, which, in turn, creates a magnetic field. This magnetic field is counter to the one created by the donut magnet and the two forces causes rotation. Eventually, the electrodes will degrade/corrode and the motor will stop.

[Flyingwigs]

this is cool and all, but i could turn the same mass at about 10% the same input with an inefficient dc motor, so not entirely practical :P

[fatdu4]

can i put this in my car?.......if not, move one.

[piespokladowy]

Very interesting!



[michalchik]

Are you sure this is a magnetohydrodynamic motor and not a homopolar motor?

[gilbondfac]

@michalchik No ! it's MHD in fluid (lorentz force)

[michalchik]

@gilbondfac After re-watching carefully the later part of the film with the lid off, I think you have both. It looks like the fluid is going in the opposite direction. Fix the metal in place and put some glitter or other inert tracers in the fluid to follow its flow.

[DragonFlyback256]

@gilbondfac

Homopolar motors use Lorentz force too. It pretty much looks like one to me as well.

On the funny side, it makes a great electrolite stirrer. xD

[FreeEnergyNow1]

@michalchik

Just another scam, the acid and copper plates is a basic battery. The magnet acts as the stator, and the rotor rotates these are the basic scams today!

[michalchik]

@FreeEnergyNow1 gilbondfac is not trying not a crazy perpetual motion guy, everyone knows this is a electrochemically powered. The only question is, is it moving because of hydrodynamic or homo polar type mechanisms.

[michalchik]

@A1Skeptic Cruel but funny. Sometimes the point is just to demonstrate it can be done.

[cervantesphantom]

Excelent experiment! Congratulations for the design! You always surprise me with new, excelent and amazing experiments! Imagination empowered to teach physics! You're a real physics guru! Cheers!

[m3sca1]

amazing demonstration

[richcollins513]

if you heat a speakers magnet with a torch it will loosen the glue that holds it in place and your magnets wont be chipped from flat head screwdrivers and hammers. Nice device...

[JamesThomas]

What are the gases being released at the center core? Can these be harvested?

[gilbondfac]

@JamesThomas Hydrogen: of course you can do it.

[pubtor]

anyway to get a electricity free fan?

[piranha031091]

Très joli, mais je n'ai pas compris l'intérêt du bichromate de potassium?

[gilbondfac]

@piranha031091 un dépolarisant pour éviter que l'intensité décroit trop rapidement le long des électrodes de cuivre (production hydrogène)...phénomène très connu dans les batteries ou piles

[gilbondfac]

@piranha031091 de plus on évite une oxydoréduction trop rapide

[speedomike747]

Hey I had a question.

Cuz I have a idea(mayby world changing :D)

[gilbondfac]

@speedomike747 ask your question!

[speedomike747]

@gilbondfac O sent u a PM

[batteryphil]

very impressive! can you redo with rare earth magnets now?

[gilbondfac]

@batteryphil yes come soon

[mecrazy5]

Fukkin magnets..
