***** Thanks for the reply dude. Luv the way you present science, unpolished and completely connectable to curious minds. You truly are an inspiration. Even for a 44 year old fart like me. How's the mine coming along. Curious to see how much of the entrance you have dug out.
+Cody'sLab Check out MP3 Gain. It's free which is nice. If you produce a test audio file as an MP3 you can measure the sound level in dB. I don't recommend actually changing the sound level with this tool as it will degrade the quality of your audio. To that end it's better to change the sound level in some other program and test again. This will let you produce consistent sound volumes in your videos.
Things like electrochemistry are why I wanted to study Chemical Engineering. Organic Chemistry is what made me dump that option, so now I'm learning how to put a plain on air instead...
Cody just started subscription after seeing your video on explosion welding. I had already been watching u for a while. That was a really neat reaction to that, it felt very personal. You inspire me to be science oriented!!!!
I've always wanted to try this with Pure Nickel metal, as it's in the same Vertical row as Platinum on the ptoe. It also seems to have the ability to absorb hydrogen gas too, maybe lots more under pressure
Yeah, a nickel anode and a silver cathode. One source I found said that the voltage potential on one of the electrodes increases with the log of pressure. The temperature can also be increased up to the boiling point. This is extremely corrosive though. Don't touch! Vp(mV) = 1.5 T(Kelvin) log(P2/P1) (Vp = cathode potential? in millivolts) Vn(mV) = 4.0 (T2-T1) (Vn = anode potential? in millivolts)
Hey Cody, I've done quite a bit of research into building fuel cells, and I want to warn you that you're going down a dead end with this design. You're patterning your cell off of the Grove Cell, which suffers from 3 big problems: A) Power output is related to the distance between the two electrodes. With the grove cell, you'll never be able to get them very close together. B) Power output is related to the surface area of the electrodes. with the wire, you're kinda stuck in a corner on this one... C) The grove cell takes up a LOT of space compared to other designs, so it's not easily stackable. Look into the Bacon cell and sintered nickel gas-diffusion-electrodes. It's a flat design, so it's easily stackable, the electrodes are extremely close together, and the electrodes have an extremely large surface area. Another big plus is that you might even be able to nix the platinum altogether. The basic cell design is two electrode plates, between which is a very thin spongey or cloth material that holds the electrolyte. Gas is forced under slight pressure into the electrodes, so that the electrolyte and the reactants meet inside them. PM me if you'd like more information!
What if you try nickel(it will not corrode in lye even under voltage, and some forms of it are catalytic) instead of Pt wire? You could try even nichrome wire if not having pure Ni, will you try?
Interesting concept. You could cover the potassium hydroxide solution with silicon oil, to prevent the formation of potassium carbonate from the CO2 in the air.
Thank you so much for the information. I watched grant thompsons video on his hydrogen fuel cell but, I didn't quite understand it. Also I hope to try this.
+Cody'sLab a tip. Even if you have problems with your software, If you could afford, record the audio with a separated good microphone. It does wonders in the video. Your channel rocks!
Cody what if you casted a sponge and put the mold into ice, then you pour platinum inside the mold and after a few seconds suck out the still liquid platinum. you'll be left with a maximum surface area hollow sponge.
+Liquid Metal (Lear) to make that work you would need a shit ton (technical term) of platinum, to be able to pour it, and to have some still liquid after a second of it touching the cold mold :P stuff's hella expensive
I have a box of solar cells and I've given up trying to solder them. Even with my expensive, regulated iron and a broad tip and silver solder, they keep cracking. Looking forward to hearing your tips.
As you said bigger surface area = more power. i have hand crank rolling mill, i have used to thin out silver for catalytic oxidation of stuff. so far only acetone and paint thinner have worked for me. what in trying to say is thin the platin out like leaf gold or somting.idk continue your great work.
Those are the smallest dang bottles... Hey Cody; Ill be in Utah on the way to Cali. we sent out our 8 truckloads to cali already. 3300 Colonies. I'd really like to visit with you someday- given my original passion (From Montana ;) ) was Geology, and I am now I Raise my own queens mainly by grafting but I have a few other tricks. I am the age give or take (I'm 35) and It seems logical that we meet. Oh and BTW- Fellow red headed beard; and proud of it!
+TheMontanaDave You get good prices on Topaz there? Buddy has a 258 Gram Beautiful specimen, I just can't cough up the 5k ish or more its worth. We have a Gem show coming up soon, maybe he will have some luck there. I have a friend that is an undergrad at MSU in the Bio-Chem. Ironically he go Malaria in S. America. They are now taking samples and studying Propolis. His goal- To Cure Malaria via Propolis. Now that stuff is crazy... I found a Mouse/Snake and a bat in hives that had got killed and the bees merely covered them over with Propolis. Now they are using on burn victims to prevent infection and pills to help with ulcers. Got to love them Ladies!
it should but the platnium would need to be in solution aqua regia being the acid to use you end up with chloroplatonic acid... the issues you will end up with is the platnium burning off the copper...
Hoping you will do something on solar panels! Particularly interested in encapsulation. I think I've watched all of your videos, and I don't think you've ever detailed the off-the-grid power system on your ranch. Very interested in this, too. Thanks!
you could have predicted your cell voltage from the half cell potentials (0.4-(-0.8))... agrees quite well with experiment! had you used an acid electrolyte, you'd have made the actual 'standard hydrogen electrode' which was used to reference other half cell reactions (as 0.00v) :-) very nice!
Semi-related question. What would be more efficient for converting electricity into kinetic energy: an electric motor, or using electricity to run water through an electrolysis cell and then use the resulting gasses to run an engine?
Supposedly it is said that one can make an alkaline fuel cell like this with a nickel anode and a silver cathode. Among the metals, Silver has about the right bonding strength with oxygen for the oxygen reduction reaction.
In another youtubers video you said that you would attempt to produce and distill methanol, is there a date we should be waiting for or are you simply going to do it eventually?
2:15 I'm going to make one and design one for my laptop, because the battery discharges too quickly and the batter replacement is too expensive. I'm happy I took Chemistry, so I know about hydrogen fuel cells and how they work, but am researching further to try and design a small fuel cell that can work easily with my laptop.
Hi! what if you hammer this wires, their area will increase dramatically. By the way, 0.5mA should be enough for led to give some light even lower, its voltage need to be more
It wasn't until I went to California and saw one there, that I found our sunrises in Utah (along the Wasatch front) are kind of unique. We don't get much dawn light here, it's dark, then the sun's up. (just saying cause I noticed at the end of the time laps we see sunrise)
Could you power a car with a bigger version please? much more platinum / surface area... foil sheets? Sheets rolled around a "spongey" material... H2 and O2 separate? Can it run on liquid H2 O2? Maybe the gas can not only "power" it but super cool something towards lower resistance... dunno.
Been a fan for a while. Came across this video while looking for a substitute to lithium ion and lithium polymer batteries. Do you think the hydrogen battery would be able be more energy dense than LiO/Lipoly batteries? When are you going to scale this up?
my understanding is that hydrogen fuel cells work by recombining the hydrogen and oxygen to for water and use the movement of electrons from this process to create electricity. question: where are the hydrogen and oxygen recombined? do ions travel through the electrolyte and which ones?
why some fuel cells or electrolyzers can make hydrogen and oxygen without potassium hydroxide, from pure water? How much efficiency you achieve using platinum? I wanna know if it is possible to make a reversible fuel cell myself and if I can achieve at least 60% efficiency in electrolyzer and 40% for the fuel cell. I know that the state in the art is at 93% and 60%
is 19.5V, 3.3A and 65W (Laptop charger Output)enough for electrolysis? If yes how much HHO production can i expect? Pls answer it'll MEAN and HELP a LOT.
wasn't the problem with hydrogen that it diffuses even through solid steel? (as evidenced by the fact that your HHO torch tanks were missing about 50 psi when you tested them)
not as fast as iron, sure, but it still permeates through aluminium at about 10^-10 Mol/((meter*second*Pascal)^.5) (compared to about 10^-9 for iron) (according to www.rebresearch.com/H2perm2.htm at least) EDIT: wait... this is at 700+ degrees celsius,i thought it was at 70... extrapolating the number gives me about 10^-17 for aluminium, compared to 10^-11 for iron you're probably right in saying that aluminium is your best bet though :P unless you wanted to make them out of gold xD
actually i sorta have an idea for a neat experiment due to that unit (mol/M*S*Pa^0.5) i figure that, because the external environment doesn't really contain hydrogen gas, it should leak out of a sealed container until the internal atmosphere is an almost perfect vacuum (hydrogen leaks out, helium is hardly present in sea-level atmosphere, and the next gas is nitrogen, which is 14 times heavier and will therefore not permeate through the container)
Hey, even I tried this with 4 cells in series and it's only generating a voltage of 2.6V and current of 0.11mA and it's not enough to run a 3V motor. Can you please help me out?
Try making a methanol fuel cell it's almost like a hydrogen fuel cell but it's much safer and some buildings use methanol fuel cells as a back up power supply for when power goes out :)
+Mote of Dust It was a looping 8 hour time lapse. If you can't deduce what is shining through the window 8 hours into the night, then I don't know what to do.
***** Ok. Imagine it is about 11 PM. Add 8 hours to that. Imagine that time passing in about a second and a half. What thing comes up in the sky as morning comes? What very bright thing could be shining through his windows at 7 AM?
Excuse me Cody'sLab, can you list down the materials and variables needed to make this Electrochemical Hydrogen Fuel Cell? Am I allowed to make a fuel cell like this in my research? Thanks.
One question. In don't know any of these stuff, I'm just told to make something to present at school. Can this power a dc motor even at a low rpm? Doesn't really need to be fast
Cool video but next time can you raise the audio level a bit? I had to crank up my speakers to hear your voice, then quickly lower the volume when the ending music came up. Thanks
You can substitute nitrogen doped carbon nanotubes or N-doped graphene for the platinum For cheap proton exchange membranes you can use PVA chitosan h2s04 gel electrolyte. Trust me unless you are going to invest in a sputtering setup platinum will break the bank before you have a system big enough to matter.
Was reminded of something when I saw diy solar panels at end......Has anyone ever heard of using sterling engines as generator? I do not know how plausible the science behind it is, but supposedly you can concentrate sun onto a sterling engine with mirrors and it will produce up to double the amount of electricity then solar panels. Idk how true this is, or if just a concept. Comment if anyone knows if this is true/false. thnkz
Sterling engines can be used for solar power generation, but they are much less efficient than a solar cell. The efficiency of a normal solar cell is somewhere between 22 and 40%, while a sterling engine has an effieciency of around 1.5 - 3%
+Clyde Connors Sterling engines have a theoretical max of 40% efficiency to convert heat energy to mechanical energy which is better than most solar panels but by the time you have made that into electricity solar wins because you dont have alternator losses. Here is an engine that I made: th-cam.com/video/H85DJwRyaIk/w-d-xo.html
A silicon solar cell is around 15% efficient. A toy Stirling engine is likely around 1-3%. A power-producing Stirling engine is typically around 10%-20% , around half of the theoretical max (Carnot) efficiency.
those actual stirling engines are not perfectly made they use the stirling cycle wich is ideal but their construction and build isnt the best and most efficient design of stirling cycle i saw, were the freepiston one using compressed hydrogen as themodynamic gas
+Cody'sLab: I absolutely love your videos! They're filled with so much amazing information and are always very procedural and detailed. My sincere gratitude goes out to you for constructing these amazingly educational and entertaining videos! Keep up the great work! I'm certain your videos may have an impact upon the world as some great mind liken to yours will eventually make some pivotal use of some slice of knowledge you so kindly share with detailed explanation. Again, thanks Codey. :)
Hey guys I was planning to do a chemistry lab experiment on these fuel cel and was wondering about the independent variables that I could change to study the effect it has on another variable. So far I’ve been thing about changing the concentration of KOH on the effect of current change supplies with a constant voltage (9V). Anyone have any other suggestion?
and they say that there will be a war for water... solar pannels, sea water and decombining hydrogen and oxygen from it THEN recombining it to pure water is all that is needed! now if it needs minerals, those could be added later! so by building a hydrogene battery they fixed the future problem of water...
Sorry about the audio quality, I'll look into the issue. Perhaps its just time to upgrade my editing software.
+Cody'sLab Do you study at university or are you a backyard scientist?
baarni
Both I guess.
***** Thanks for the reply dude. Luv the way you present science, unpolished and completely connectable to curious minds. You truly are an inspiration. Even for a 44 year old fart like me. How's the mine coming along. Curious to see how much of the entrance you have dug out.

Dude your videos are insane! You deserve much more subs than you already have!

Next week, the DIY *Thermonuclear* Hydrogen Fuel Cell.
+Gareth Dean
Try next month. ;)

I wouldn't put it past you, I know it's possible to fuse hydrogen on a benchtop.
Cody just started subscription after seeing your video on explosion welding. I had already been watching u for a while. That was a really neat reaction to that, it felt very personal. You inspire me to be science oriented!!!!

+BasementBen
look up nickel hydrogen battery. "The negative hydrogen electrode utilises a teflon-bonded platinum black catalyst"
Yeah, a nickel anode and a silver cathode.
One source I found said that the voltage potential on one of the electrodes increases with the log of pressure.
The temperature can also be increased up to the boiling point.
This is extremely corrosive though. Don't touch!
Vp(mV) = 1.5 T(Kelvin) log(P2/P1) (Vp = cathode potential? in millivolts)
Vn(mV) = 4.0 (T2-T1) (Vn = anode potential? in millivolts)

Yes and silver for the cathode. Silver has about the right bonding strength with oxygen for the oxygen reduction reaction.
I'm a dumb person no idea why I love your videos but don't stop your projects they're awesome
seen you playing with solars at the end, can you make a vid of you making a solar panel that would be awsome
I made one with a 500mm² platinum surface a long time ago.
Works great but the oxy-hydrogen explosions are not so great so I changed for ANFO.
+Sceeker lol XD
Are we going to sometime see a bigger version of this some time in the future?
Interesting concept. You could cover the potassium hydroxide solution with silicon oil, to prevent the formation of potassium carbonate from the CO2 in the air.
This is like *the only* problem with Alkaline fuel cells. Pretty amazing devices.
Thank you so much for the information. I watched grant thompsons video on his hydrogen fuel cell but, I didn't quite understand it. Also I hope to try this.
Realy enjoy watching your video's keep up the good work.
i think the audio is fine, and cody i think you and your channel are awesome. thanks you !
Thats so clear and quick. Really interesting .
I'd love to see what kind of things you could power if you used a jewel thief to increase the voltage
+Cody'sLab a tip. Even if you have problems with your software, If you could afford, record the audio with a separated good microphone. It does wonders in the video. Your channel rocks!
Cody what if you casted a sponge and put the mold into ice, then you pour platinum inside the mold and after a few seconds suck out the still liquid platinum. you'll be left with a maximum surface area hollow sponge.
+Liquid Metal (Lear) You could make the mold out of something you can chemically desolve to extact the sponge properly

Great demo. I think if you pitted the wire by sand blasting, etc. you could increase the surface area.
Would it be possible to electroplate the copper wire with platinum in order to use the expensive metal more efficiently?
it should but the platnium would need to be in solution aqua regia being the acid to use you end up with chloroplatonic acid...
the issues you will end up with is the platnium burning off the copper...
Or just use a nickel anode and a silver cathode.

Semi-related question. What would be more efficient for converting electricity into kinetic energy: an electric motor, or using electricity to run water through an electrolysis cell and then use the resulting gasses to run an engine?
Does platinum not react with oxygen at all or is it just extreamly mild?
+Justin Brown
Oxygen does react at the surface but is easily removed by other reactive atoms.
+Logan Bowers
That was with hydrogen mixed in.
+Logan Bowers no. There must be at least two reactants for a reaction to occur. The platinum is only the catalyst, not a reactant
Being a catalyst, platinum will react with the oxygen and release it with little extra energy needed
Supposedly it is said that one can make an alkaline fuel cell like this with a nickel anode and a silver cathode. Among the metals, Silver has about the right bonding strength with oxygen for the oxygen reduction reaction.
In another youtubers video you said that you would attempt to produce and distill methanol, is there a date we should be waiting for or are you simply going to do it eventually?
If you need more surface in small space: Maybe you could re-use old catalyst from a car exhaust. (if you can get hand on some with platinum in it).
2:15 I'm going to make one and design one for my laptop, because the battery discharges too quickly and the batter replacement is too expensive.
I'm happy I took Chemistry, so I know about hydrogen fuel cells and how they work, but am researching further to try and design a small fuel cell that can work easily with my laptop.
SOLAR PANELS.... when?
I wanna know about the panels at the end, what were you doing? removing old solider? I would love to see a photovoltaic video series
he sows you in the video after this :)
I combed through all the videos and found it. thank you
nick and Aaron
XD
Cody in 2050 be like: Hi everyone, welcome back to Cody'sLab, today im gonna build a space ship out of some materials i found in my backyard.
Looking forward to the possibility of a video with a bigger and more efficient version... but even this is pretty impressive.
What are the blue flashes in the background?
The sunrise. It was an 8-hour timelapse.
if you don't find platinum wire, is there maybe some other metal that can be used and doesn't corrode instantly when used ?
Hi! what if you hammer this wires, their area will increase dramatically. By the way, 0.5mA should be enough for led to give some light even lower, its voltage need to be more
+Uterr
yes, I need about 3 volts. so 3 or more in parallel should work but I need more platinum.
+Cody'sLab in parallel you will get 3x current, not voltage :)
It wasn't until I went to California and saw one there, that I found our sunrises in Utah (along the Wasatch front) are kind of unique. We don't get much dawn light here, it's dark, then the sun's up. (just saying cause I noticed at the end of the time laps we see sunrise)
0.5mA will totally light an LED, not very brightly, but 1.2V is too low for any visible LED.
Could you power a car with a bigger version please? much more platinum / surface area... foil sheets? Sheets rolled around a "spongey" material... H2 and O2 separate? Can it run on liquid H2 O2? Maybe the gas can not only "power" it but super cool something towards lower resistance... dunno.

+mysterioushooded
Yes ions move through the electrolyte
ok thanks
Why we apply flame to platinium metal. Any major reason behind it 😊
Why did he use potassim hydroxid instead of regular table salt
why some fuel cells or electrolyzers can make hydrogen and oxygen without potassium hydroxide, from pure water?
How much efficiency you achieve using platinum?
I wanna know if it is possible to make a reversible fuel cell myself and if I can achieve at least 60% efficiency in electrolyzer and 40% for the fuel cell.
I know that the state in the art is at 93% and 60%
Just what I was looking for!
If there was more platinum wire in it would it discharge faster?
is 19.5V, 3.3A and 65W (Laptop charger Output)enough for electrolysis?
If yes how much HHO production can i expect?
Pls answer it'll MEAN and HELP a LOT.
wasn't the problem with hydrogen that it diffuses even through solid steel? (as evidenced by the fact that your HHO torch tanks were missing about 50 psi when you tested them)
+Sirius Black
I should be ok with aluminum tanks.
not as fast as iron, sure, but it still permeates through aluminium at about 10^-10 Mol/((meter*second*Pascal)^.5) (compared to about 10^-9 for iron)
(according to www.rebresearch.com/H2perm2.htm at least)
EDIT: wait... this is at 700+ degrees celsius,i thought it was at 70...
extrapolating the number gives me about 10^-17 for aluminium, compared to 10^-11 for iron
you're probably right in saying that aluminium is your best bet though :P unless you wanted to make them out of gold xD
actually i sorta have an idea for a neat experiment due to that unit (mol/M*S*Pa^0.5)
i figure that, because the external environment doesn't really contain hydrogen gas, it should leak out of a sealed container until the internal atmosphere is an almost perfect vacuum (hydrogen leaks out, helium is hardly present in sea-level atmosphere, and the next gas is nitrogen, which is 14 times heavier and will therefore not permeate through the container)
+Sirius Black
It would actually create a slight vacuum, far from a perfect vacuum though.
Cool I can't wait to see the big one
as normal I have very little clue of what is actually going on here.... but I can't seem to get enough of it... give me more.....
Are you sure the gas isn't diffusing in the water?
+Davi Poyastro
It probably is a little but hydrogen has a low solubility and the gas loss seems to have stopped when I unhooked the wires.
+Cody'sLab I might add that the two gases dissolve in amounts way different from each other yet they change the same amount
Hey, even I tried this with 4 cells in series and it's only generating a voltage of 2.6V and current of 0.11mA and it's not enough to run a 3V motor. Can you please help me out?
wow i'm literally doing this in chemistry at school :D
I would personal amplify the sound and re-upload, can't make out a thing on stock monitor speakers :/
Another dead end project....unbelievably cool thou
Try making a methanol fuel cell it's almost like a hydrogen fuel cell but it's much safer and some buildings use methanol fuel cells as a back up power supply for when power goes out :)
what was the flashing during the time lapse? also it seemed as though your camera was moving ever so slightly when each picture was taken. Weird!
+Mote of Dust It was a looping 8 hour time lapse. If you can't deduce what is shining through the window 8 hours into the night, then I don't know what to do.
***** Ok. Imagine it is about 11 PM. Add 8 hours to that. Imagine that time passing in about a second and a half. What thing comes up in the sky as morning comes? What very bright thing could be shining through his windows at 7 AM?
your channel is always intresting keep it up bro
You used shoe goo to glue this together?
How about silver solder wire instead of platinum?
What happened to the heavy water series? those were amazing.
Excuse me Cody'sLab, can you list down the materials and variables needed to make this Electrochemical Hydrogen Fuel Cell? Am I allowed to make a fuel cell like this in my research? Thanks.
Nice was about to go to bed but new video yay
Cody Make a crystal cell with copper and magnesium and an electrolyte :D those generate alot more
One question. In don't know any of these stuff, I'm just told to make something to present at school. Can this power a dc motor even at a low rpm? Doesn't really need to be fast
This is awesome! would this work with stainless steel too or is platinum a nescessity?
Cool video but next time can you raise the audio level a bit? I had to crank up my speakers to hear your voice, then quickly lower the volume when the ending music came up. Thanks
+Acksull
Ugh! I thought I had that problem solved... I'll see what I can do.
You can substitute nitrogen doped carbon nanotubes or N-doped graphene for the platinum For cheap proton exchange membranes you can use PVA chitosan h2s04 gel electrolyte. Trust me unless you are going to invest in a sputtering setup platinum will break the bank before you have a system big enough to matter.
So in order to increase voltage, I have to increase the size of the could for better surface area?
Was reminded of something when I saw diy solar panels at end......Has anyone ever heard of using sterling engines as generator?

A silicon solar cell is around 15% efficient. A toy Stirling engine is likely around 1-3%. A power-producing Stirling engine is typically around 10%-20% , around half of the theoretical max (Carnot) efficiency.
those actual stirling engines are not perfectly made
they use the stirling cycle wich is ideal
but their construction and build isnt
the best and most efficient design of stirling cycle i saw, were the freepiston one using compressed hydrogen as themodynamic gas
50mA I certainly more than enough to power a regular led!
i wonder what you could power with a much larger version of this
+Cody'sLab: I absolutely love your videos! They're filled with so much amazing information and are always very procedural and detailed. My sincere gratitude goes out to you for constructing these amazingly educational and entertaining videos! Keep up the great work! I'm certain your videos may have an impact upon the world as some great mind liken to yours will eventually make some pivotal use of some slice of knowledge you so kindly share with detailed explanation. Again, thanks Codey. :)
Can we get electricity from the reaction within a catalytic converter on a vehicle? I know they heat up. Is that heat waisted electricity potential?
What's your degree(s) in, I see you post such a wide range of complex things it's crazy.
Hey guys I was planning to do a chemistry lab experiment on these fuel cel and was wondering about the independent variables that I could change to study the effect it has on another variable.
So far I’ve been thing about changing the concentration of KOH on the effect of current change supplies with a constant voltage (9V). Anyone have any other suggestion?
and they say that there will be a war for water... solar pannels, sea water and decombining hydrogen and oxygen from it THEN recombining it to pure water is all that is needed! now if it needs minerals, those could be added later! so by building a hydrogene battery they fixed the future problem of water...
im sorry man are you in fact using a battery in that? cause it sounds like your using more energy than your getting back.
Yeah it's not a very efficient battery because electrolysis is inefficient, but it does work!
Please tell the music name from the end.
definatly gonna watch this
How thin is your Platinum wire? 0,2 mm in diameter is ok?
Could you use a carbon electrode instead of platinum? or would that dissolve into solution?
I did some reading on Alkaline fuel cells, and it should be possible to use a nickel anode and a silver cathode.
How much did you pay for that amount of platinum wire?
Could you try to make phosphorus out of phosphate rock/cow skull you found when looking for meteorites?
What are you doing at the end?
What type of gloves were you using?
Thanks For This Video.
Now I finally have a reason why I bought potassium hydroxide
I'm going to try to scale this up but with a 1000 ml beaker and test tubes
I can't do it now bc I have pneumonia but I'll try
+Victor Fiori try uploading the finished product? :D
ok but I have to order some platinum wire unless I could use something else below this I will comment with my other channel.
+Marty Camenzind this is the channel I will upload it on. plz subscribe :D
can u show how to desulfate a battery?
thanks
You ever going to cover precious metal recovery from computer chips?
+Rezzy Beans
yes
Is there a way to make it on a bigger scale.
Did you scale up this setup?
Is there any sound?
Its fun to listen to you :D..... 99.9999999% i have no idea what you talk about but oooooooh funky stuff :D
What was that at the end?! DIY Solar cells?!
Anybody know approximately how long it takes to create enough gas in the cells to see voltage when I connect it to a voltmeter?
are you making a solar panel?
