- Characteristics: 4 cells of 1.5 volts for a total of 6 volts and a current of 35-40 mA. The running time is approximately 30-35 minutes. To restore power to the battery to replace the salt water and ready for the new energy. This battery also works with water and salt, but the duration of the charge drops to 10-12 minutes, this is due because the salt dissolved in water has few active ions of sea water. The battery can be charged externally from 9 volts with only 4-5 minutes with a significant increase of the discharge time.
*The motor and leds that are seen in this video are 3 volts each. The motor used is a CD rom motor. In this experiment, I do not recommend using any type of motor for toys, they absorb too
much power.

Salam.. from Pakistan. I tried it and it worked great.
You can get these Mg rods easily.... I think they are used in water heaters.
It also works with Steel if you cannot get your hands on Carbon Rod.
Also works with soldering wire :)
I made a mixture of salt water + vinegar + few drops of oils (to slow down evaporation). It pumped around 100 mAmps :)
Talha Kamran Bravo, I'm glad that at least one person has replicated this experiment :)
Talha Kamran what kind of soldering wire? the one that they use for welding?
yes..the one used in soldering jobs.
I also tried Mg in graphite crucible and that worked well as well. I used raw sea salt as my salt. But in this scenario cell will last probably 2 months and you may need to add water once in a week. Few ml will work fine.
Her is a tip for guys making it out there. Use buck converter. It is super cheap. It is like a joule thief. It is suppose to increase 0.9v dc to 5v dc. Anything less than 5v , it will try to crank it up to 5v. It also has a usb outlet but you just connect your +ive to its +ve outlet and negative to negative. Hope that will help guys....
Peace and keep on having fun with experiments.
Copper + Mg is best
Graphite + Mg is also good
Aluminum + Graphite is cheap and is good for momentary blinking of ED's. Keep it wet no issue with decay. It will take years to decay them as compare to Mg.
With Copper and Mg. First put your copper in them cleansing agents that when dissolved in water forms an acid type of solution that can clean pipes and utensils. Dip copper in it for few minutes to deform the top layer of copper. Can do same with Mg but be careful Mg will react very quickly. Do it out in open with safety.
Thanks for the comments :)
Salam....I used a Mg ribbon and tried it with used BBQ charcoal (cracks in it). Soaked a paper towel in a solution of (salt+50% vinegar + 45% water + 5% vegetable oil to slow down evaporation). Wrapped the charcoal in towel and then wrapped Mg ribbon around it. It lit a small LED for 2 days :)
Great video, great atmosphere, requires no dialogue at all : ) Thanks for the upload...
jdcproducts Thanks friend :)
yes his videos requires no explanation.. even a cat can understand after watching it

What is the life of the graphite and magnesium electrodes?
Love the concept! I have tried two metals, including this one and using copper and zinc. They actually both work the same! Thanks so much for the video! This concludes that bieng very green, by using the salt water from the ocean! Love the atmosphere!
I tried something similar today with regular salt water, iron and zinc coted plates and it works a treat. I am only powering a small LED but, it works well and it still makes me smile. I made a battery today.
@Ma Ramon
The battery develops more or less 6 volts. Each cell 1.5 volts.
+Drone Legion Yes, it is able to load with 6 volts, but only for a limited time to 30-40 minutes, then to it you have to change the water ;)
+Drone Legion The only drawback of this is that it wants sea water to give 30-40 minutes charge, only with water and salt it gives half the time. The sea contains many active ions to generate power, water and salt has no.
+Drone Legion Your idea is not bad :)
+Roobert33 if it is put in the sea will the battery generate electricity forever?
+Roobert33 that makes want to live nearby the seaside building with pile of magnesium stock lol
Thank you so much for Electric Experiments Roobert33 for showing magnesium, graphite useful experiment.
naaah, that's not powered by salt water. It's powered by fukushima.
Outstanding research 😎
One of my favorite Roobert videos.
How many cycles does the magnesium last for if recharging with say solar panels instead of constantly changing out the water?
sir , may i know what type wires have you used?
and can u tell us that should we use a salt bridge and try this process?
I'm really impressed with this but what current were you getting there? I think this system could be easily implemented on a ship lol. Scaled up a lot
Hi. I will make my Science Fair based on this. Where I can find/purchase these cells:magnesium and graphite ?
Sorry, also can we duplicate that and use converter to get 220v from 12v?? thanks alot
@Electric Experiments Roobert33
Could you explain the chemical reactions going on in this type battery?
Is the magnesium or the graphite disolving into a solution with the salt water?
What is the chemical equation?
Uhm can i ask what are the things that did you use?
Thank you for opening up my mind : imagine if boats could use this!!!. WOW!!
I guess you could add a lot of these glasses + solar panels + reserve energy + energy generated by the engine rotation to make a boat work :)
What are the dimensions of the tank, the graphite and magnesium rods you used?
Magnesium is the 8th most Abundant elements in Earth's crust.
Magnesium is very cheap, +-2.00 per pound if bought by the ton, and it's very light. But they will corrode on the outside, using a continuous feed of very thin magnesium strips seems to be ideal. and it cost very little. Scientists are working on magnesium batteries that will most likely change the world. And will never need recharging... as long as you have magnesium.
Oh and yes, magnesium sulfate is recyclable.
What is the discharge time of this batry
Hi, Thanks for the video, this is awesome. I'm just wondering two things:
Would this current be enough to charge a cellphone? I know its not nearly as much as a regular charger, but would it bring it back to life if the battery was dead.
And is there any way to do it without the cups, just by sticking the rods in wet sand? maybe using plastic plates as insulators between the pairs of rods.
Simon Lopes The current which is generated between bars is quite sufficient to charge a phone. The absorption phone is less than what you see in the video. The bars can also be put in the wet sand, it does not change anything..
Where did you find the cylinders of magnesium and graphite
where can we buy that magnesium electrode? and is Magnesium Element Metal Rod can be use in that experiment in exchange for magnesium elecrode?? thanks for any reply
It's great !
If you live by the sea , you can make a floating platform at sea and place the electrodes in it.
This avoids having to fill salt water.
YES...
What are the half reaction formulas?
Anode: Mg(s) --> Mg2+(aq) + 2e- (Magnesium forming magnesium ions, simultaneously sending electrons down the wire)
Cathode: Na+(aq) + e- --> Na(s) (Probably incorrect, what happens here?)
Can't get my calculations to match your voltages (1.5V per cell).
Thanks,
Mg + NaCl + H2O -> MgCl +NaOH + H
Hermit Oldguy not quite right
Anode: Mg -> Mg2+ + 2e-
Cathode: 2H2O + 2e- -> 2OH- + H2
--------------------
Overall: Mg + 2H2O -> Mg(OH)2 + H2
If you assume that the electrode is porous and oxygen will diffuse through it the redox reaction looks like this:
2Mg + O2 -> 2MgO
Why does Seawater have more 'active ions' than Saline Water? Is it because water from the sea has more minerals in it?
thanks ill use those elements
keep up the good work
How long is the durability of electrical energy going on?
Old news, this worked for Captain Nemo. The Nautilus was powered with salt water batteries. But VERY cool demonstration.
Torpedos are also powered by such battery, so arming them consists of filling the battery with sea water before firing.
I thought the Nautilus was an atomic sub it may have had saltwater batteries but it generated power by splitting the atom
Cool!
nice vid. thanks. where do u get the parts for this experiment?
+kazuza9 You have to read the description of the video.
mi is very useful, the skulls asked and none knew nothing, not that way retibuirle ... thanks, thank you very much
Compact and convenient!
What happens when you drain the water between uses and seal the beekers? Is the oxide layer negligible?
Yeah.. the big question is, does an oxide layer form? This (and depleted electrolyte) is WHY batteries "run out".
Nice project i love it.
just out of curiosity what is in the black thing on the back of the piece of wood?
The black object behind the wood, it is a piece of plastic that is used to tilt the basis for a clearer vision of the leds.
great video. is there a way to find natural products to do this? I suppose in the past vinegar and lead were the most common because lead was easier to find?
+Gristle Von Raben I do not have understood correctly your question, you can better explain :)
Thank you for responding. I am always trying to figure out ways to survive in a situation where there is no electricity, but just a cell phone with information on it, like survival manuals and books. To keep the cell phone alive, I often try to find ways to make enough electricity in the wild to charge it. So far, a small dc motor with fins on the gear can make electricity if used as a water generator. But your invention here shows that it should be easier to make electricity quickly if the correct raw materials could be found and sea water was added to them.
Many people think you can just add salt to water on the mainland, but truth is, when supply lines break down, salt becomes scarce and as valuable as gold.
+Gristle Von Raben Now I get it..
All that produces current, static or rotating, draw from always something that allows it. In my experiment with seawater and bars, it works as long as galvanic corrosion does not consume them and everything ends. In practice, how you say, lead and vinegar, produce current. But then everything runs out.
But it's definitely faster than a hamster in a wheel LOL
my question is would you be able to recharge it with a charger instead of replacing the water?
Great job!I'd like to ask you the water amoubt will effect finally or only the salt inside the water(the amount of water will decreased or it will not decrease?)Great thanks!
With seawater it works very well, a lot less water and salt.
Electric Experiments Roobert33
It should work with normal water without salt. But the construction has to be changed.
I used a 1.5 AAA batery to power a drone servo, it blow a lot of air, I using it as a fan, so this is going to be an awesome Project....
great work
Replace graphene with cooper, they use the minerals still in the ground with large connectors to harvest the differentials.
Stunning piece of equipment art! What is the black rod. Very nice 👍🏼
Jessica Rossi black rod is carbon graphite

How much volts does that electric motor take up? Will it work if I use a toy motor?
Wow. Amazing.
Robert. How does one get in contact with you?
great video
thumbs up ^^
Build a floating holder for the electrodes that goes up and down with tide..Permanent Green Power....Nice demo..
Electric Experiments Roobert33
Yes, there's quite a few possible good applications, after all there is a LOT of salt water around !
MrFreddiew1 Yes :)
MrFreddiew1
Has there been any investigating on how this could mesh with the air aluminum battery being developed by Phinergy/Alcoa? Could a system be created that would use multiple power generating concepts in one power system?
Alan Blanes
Dont know, not my video...but I expect you can find out on TH-cam or by Google-ing for answers.
Nice video as always. You're awesome :)
FIEX Thanks :)
Why not use conventional/original brushless 6vdc fan for demonstration?
that's great. I am just wondering how much time you could keep the Mg bar or the other one. ? and in this duration how many watts or KW could produce? what is the weight of both bars too please?
The magnesium rod is consumed in 30-40 days running of continuous work. The graphite rod is consumed after several months of continuous work. The bars weigh more or less 50 grams each. The power in watts that can give I have not measured, just to make the video.
thanks million
Are they "consumed" by the chemical reaktion? And wouldn't the water become acidic over time?
@Electric Experiments Roobert33 Also, can you tell me the chemical reaktion?
thanks for the video and sharing. Does any of the electrodes wear out or dissolve eventually?
+aabasiry The experiment is the only one electrode to dissolve magnesium, at least one month in seawater.
Thanks.. But I'm still not clear on what you wrote. . Are you trying to say that the Magnesium did not dissolve for one month?
+aabasiry Magnesium bars you consume slowly plunged into the sea after a few months of constant work.
Thank you.
Where did you get the graphite and magnesium rods and those metal things you screwed them on to?
Rizzo's Reef The graphite and magnesium search on Ebay. The pins above the bars are steel screws that I cut to size.
how much volt of electricity does it produce
is the salt in water is converting in to energy
Legend has it he's still there waiting for the fan to stop 🙂
Only joking 35 minutes run time
wow, nice video, thanks. Can you help me, maybe you have about graphs of current and voltage for this experiments. thanks
good day sir. is there a computation for this? like the size in length and diameter of the ,magnesium and graphite electrodes affect in generating electricity. and in the sea water or salt. thanks a lot for any help. i need computation for my study.
this experiment does not require special measures to function.
Я бы не смотрел это видео так долго если бы не шум прибоя ... спасибо автору за сеанс релакса...
P.S. короче сворачиваю видюху и слушаю
I'm guessing the metals in the cell are slowly eaten away?
Is there any way to do this (electricity from salt water) that does not result in the corrosion of the terminals (ie: continuous energy for like an LED floating buoy or something).
Tom D
The bars of magnesium and graphite are not consumed rapidly within a few days of immersion in water, they always have a certain margin of time to operate. However, the corrosion always occurs in all metals, yet not invent materials immune.
Gold?
you can try to get some beach sand in it contains some places slightly radioactive thorium and should give more volts
good suggestion
Carbon+4 carbon-4 battery diodes
Or lithium flouride batteries?
Amazing.... how long did this battery bank run?
Jared Graber The details are in the video description.
I'd love to see this setup as a near perpetual contraption. I can't wait to map it out and get the idea out of my head and into reality :) Or maybe I'm just manic.
Isto ai experiencia seria gostei!!!!
if we want to create a battery like duracell per example , how can this work ? Does it need just one set of two electrodes or 4 electrodes or more??
That's easy, one of those elements on either end, with sea water in the middle.
Open ended plastic tube, graphite on one end fill with sea water n cork the other end with magnesium
I would add more than 8 electrodes since you are using seawater. If an octopus came across your battery it may want to fight or mess it up if it thought it could beat it due to having less limbs. Personally I always have 9 electrodes but only use 8. The number 9 electrode is used only to spook an aggressive octopus into thinking this octopus has an extra tentacle and may have a weapon like a claw or a glock 9. This generally prolongs the life of the cell
I am planning to build houses in coastal areas. I need 12 VDC electric power, I figure, I could make 8 sets instead of 4 sets, to get 12 VDC.
If you dip the whole sets in the ocean, which means the salt water keep renewed their power all the times. Will that last until the Magnesium or Graphite dissolved?
How many Ampere they produced? Can that device additionally recharge themselves (like car battery system)?
Salam.... I have little knowledge like you.
Magnesium rod will start decaying...
At the same time you may get some white particles collected on Mg rod over time.....
Once in a while take Mg rod out and scrub it with sand paper to get rid of that white magnesium oxide....
rooberts is it possible to make a self charging simple dc motor that runs and also charges its battery by itself like a bedini self runner?
+ Fidel catsro eu fiz a mesma pergunta em outro video semelhante!
Bonjour ,
Est ce que l' on peut recharger cette batterie avec des panneaux solaire ? Est ce que l on peut la recharger en mettant une tension au borne de la batterie
je crois qu'il dit que ca perd en capacité tres vite (dans la description)
the lifetime of the magnesium tube and of the graphite tube?
Hi
just want to ask about the volume of the glasses or the amount of water
Each glass contains about 150 cl.
cl ?? do you mean millimeter(ml) or what
1 cl equals 10 ml
Hussain Hammad it does not make much difference, what counts is the material used for the rods, the distance between rods, their diameter (exposed area), conductivity of the liquid, number of pairs, type of connection (parallel or series), diameter/lenght of wires.
If you can put one big anode in the Indian ocean and one cathode in the dead sea graphite and magnesium respectively, you can simply power the whole world..LOL!
did you ever solve the surface oxidation, with an electrolyte that dissolves the protective oxide layer
@thunder cloud then it stops functioning as a fuel cell electrode, just like the oxide passivation layer, not optimal, not solution, to stop the battery working
@thunder cloud maybe use molten tin (air fuel cell) where the oxides either float or sink to the bottom
Have you consider using magnesium and copper combination?? and by attaching a joule thief circuit to greater increase the voltage and current of the output?? Based on my research, magnesium and copper combination is deal for maximum voltage and current output, but i havent tried graphite yet..
Also, have you ever tried experimenting different salt to water ratio for maximum voltage and current output rather than seawater?? im trying to build a portable flashlight that runs on saltwater but i dont have the necessary materials yet :)
Rhenz Raizen The salt does not have enough active ions in comparison with sea water. Copper is slightly lower than the graphite.
You can not get more current with a joules thief because you musst keep the same potency (watt). If you increase the volt you decrese the current
What about two very large flat plates, mounted closely together and hung over the side of your boat?
hehehe, a good idea :)
No I really like that idea, power indefinitely, Just need to change over the magnesium when it gets worn out completely. I like that idea actually lol
you could use zinc washers and pencil leads with a lemon juice electrolyte
The magnesium rod are they expensive for that size?
Magnesium is very cheap, +-2.50 per pound if bought by the ton,
Where did you buy the magnesuim and graphite?

will the rods ever need to be replaced
Roy Slaman yes. The magnesium is reacting and will need replacement over time.
One question!
for me build a system that generates 1 amper on 12v I will spend how many money?
when will it stop?
For the long use of this can't one use Graphite for the anode and cathode?
No, graphite for the anode and cathode, magnesium and graphite.
+Micheal, energy is being produced because the graphite and Magnesium are different from each other. This is a galvanic cell. It derives electrical energy from redox/corrosion. This corrosion occurs when two dissimilar conductors (on the Galvanic series) are located in contact with each other in the presence of an electrolyte such as salt water. Graphite and Magnesium are as dissimilar as you can get; they are literally on opposite ends of the spectrum with Graphite being a Cathode (+) and Magnesium being an Anode (-) in this application. Because of the weak salt water electrolyte, you need very dissimilar conductors having very high to get any viable work out of the cell.
You have to use different materials to get a voltage. If the anode and cathode are the same material in the same electrolyte, then you don't have a battery.
if you place the setup under ocean and connect the fan through a longer wire, will the fan run forever?
It always works until the bars are consumed.
Electric Experiments Roobert33 Thanks
Some marine buoys uses this kind of batty for navigation lights, as well as the white emergency lights on life vests.
@@ElectricExperimentsRobert33 what do you mean until the bars are consumed?
@@petersmountainonejreaper6688 the reaction withers away the bars as they're eaten up by the sea water electrical reaction. You see... Aliens can neither be created nor destroyed.
The good thing about this I think is that a flow battery can be built...

Friend alright!
One question!
(Graphite and magnesium) a calculation of what would be the size of a reactor to generate 10 amps at 12V but if possible, or
if possible small so small is even better
to much
thanks one mor time friends
how many kilos?
Ricardo Oliveira How many pounds I do not know this, considering that it takes a lot of graphite rods and magnesium to cover the entire surface..
Electric Experiments Roobert33
What would happen if elecrodes are not separated by walls of cups?
Montenegro Montenegrin The electrodes must be separated, otherwise if they are joined to touch each, there is no current.
Hi! So is this a more efficient way of making a salt water battery than let's say, galvanised zinc and copper?
noleenification The electrodes are of graphite and magnesium, but also with the copper and zinc is possible to do it.
Electric Experiments Roobert33
which of the two options gives the best results?
Alan Blanes By far higher magnesium and graphite :)
Electric Experiments Roobert33 Thanks for the response...do you feel that it has the practicality needed for commercial use?
what will happen if you put all of that magnesium and graphite rods in a single square container and has a distance between each of them?
A wormhole would most probably open up and spiral all your stuff into the other dimensions. You can't get your stuff back from there, I wouldn't recommend it
It might work depending on how far they are apart from each other but it would more inefficient.
The sound of the waves and of the fan remind me of the old computer game called "Myst."
how will you compute for the voltage output of the battery from the chemical reaction? can i estimate the output and will it increase depending on the size of the electrodes?
+Benson Arcenas The calculation of the voltage is determined automatically by the reaction of the elements with water and salt.
do you know the formula to compute for the voltage output?and what are the factors that affects it?
example: if i increase the size of the size of the electrodes will it increase its voltage?
+Benson Arcenas increasing the size of the electrodes the voltage is always the same, only increases the direct current power.
so i can only increase the voltage by making a series connection?
Protect with conductive ink based on graphite
What would happen if put the cathode and the anode in the sea?
Would the battery last "forever"?
Albin9000 Yes, it gives current sea until the electrodes are not worn out.
No, el magnesio también se consume
Daniel Twingo Y yo no escribí que son consumidos ambos en el mar?
Electric Experiments Roobert33 no sé =)
Sir what is the material in your video to performed that kind of immortality
He used many materials. And also, fix your grammar!
May I know what have u used to connect the carbon and graphite rod of two different glass??plss
you can use any conductive material. Copper or Aluminium are common and suitable
ladi jada Aluminium is completely unsuitable it will corrode away like nothing because of its redox potential
@@GreenCaulerpa it's not in the electrolyte; I don't see the issue
ladi jada carbon rods are - unless you use graphite - porous and will therefore soak up the electrolyte which leads to corrosion. Stainless steel would be a better option to use.
@@GreenCaulerpa These rods are purportedly graphite. Also, they're connected to the interconnects with a metal screw, having two nuts and a plastic clip between the interconnect and the graphite.
Perhaps the screw & nut will be having a hard time (and could be stainless steel, as you suggested); the interconnects: not so much.
What type of Graphite are you using?
the kind made of carbon 🤦♂
Do was are the rods
