1658 A DIY Battery That Is Crazy Simple To Make

[@officialsterlingarcher]

Boss, tell them that Zinc sulfate is more soluble in ethylene glycol. When you construct a cell using that as your electrolyte and you use zinc foil, the paper claims after 10,000 cycles the capacity is still 99%. It's what I call the forever battery. I'm glad to see you found out about the Zinc Iodide battery.

Dear Robert I would like to share an idea, it has nothing to do with this video but I find it interesting, a few days ago I saw a video of what happened in a jungle when the sections of a bamboo plant were cut, and how pure and clean water emanated from each of the cavities of the bamboo sections and how it was stored there, and how these sections behaved as natural osmotic membranes and taking into account the high resistance of bamboo, it seemed to me that this could have interesting applications such as chemical leaching of some contaminated water or use as separators in batteries, or filters to desalinate water, more ecological and economical and easy to build I leave that idea there in case it may seem interesting to you

Dang it! You make these videos faster than I can keep up! I'm not complaining. So, I am looking for a battery idea that is fairly simple and uses inexpensive materials. I have a large footprint, like a small parking lot, so space is not as much of an issue. I have looked at the molten metal ideas but am wondering if you are aware of any other groovy ideas I may not have heard of. Things an old farmer might be able to manage. Thanks, and please continue with your videos. I absolutely love them!

[@MikeGrayM70]

I love these DIY battery ideas. I want to try one made from aluminum and copper. The fellow who I saw made his with a separator made from paper towels with a PVA glue coating on one side. Supposedly, this protects the copper from degradation, though the aluminum eventually has to be replaced. I produce mountains of empty soda cans each year, so any battery I could make with aluminum would be great since I have that material abundantly available.

[@captainnemo6655]

If aluminum is your wish.... Have you ever seen the souvenir penny machines? The ones that flatten and stretch out the coin? Those do something funny by unintended consequence... Each pressed penny is a cathode plate. If you sandwich some cardboard or paper soaked in electrolyte and add a thin sheet of aluminum on top, then make a repeating stack about 9 coins high... You get a copper aluminum coin battery.

@@brettmoore3194 we can complain you realise. There is an engineering solution available that would save the majority of humanity - from at the very least the idiotic oil war. I just can't find anyone who really wants to, as they hardly understand the problem. The problem is of course hidden knowledge. The science of the human mind has advanced to the extent that human nature can be predicted. Our structures use these principles against us for not being organised enough to object. The lone voice of the whistle-blower blower is supported in principle but as all the money of society is controlled through structures designed to manipulate human will. There is no money to pursue the concern and the money suggests the brave individual is a grifter. Anyway I share your feelings, if you can find a few more folk that understand the science. I really don't know how much science you need to read the IPCC report. Our intention to be greedy, selfish but full of good intentions is actually the motivation for the suicide occurring. Our desire to selfishly face no bad consequences for our actions by deferring to those that pay us means all leaders are ignorent of this deception - instead trusting to the corporate protection of reasonable doubt. If there is reasonable doubt it suggests unreasonable profiteering at work. The climate data is very carefully considered information. It might be the best scientific data humanity has ever held. It is really clear. Global war is not even on the top 100 ideas to fight these issues. With a healthy economy it might feature but as we have printed money to run everything at the ragged edge. It looks a bit more like protection money paid to the military by those responsible for the impending catastrophic events. I bet they wished we all went back to believing the earth was flat so they could blame the devil. Data suggests our leaders are killing us and we all know it we just wish it was not true.

A lot of outdoors stores and survival stores do not have ANY of this stuff required to make simple primitive primary batteries in a survival situation. Like for my purposes a kit would be just the wires, the carbon and zinc mesh, the salty iodine and a foldable pouch or maybe all that stuff plus something like a few rods of carbon and zinc plus some hollow sections of pipe for other battery types like earth and mud batteries with a simple diagram on how to stick em together. This would be the perfect emergency battery survival kit for the outdoors types like me. A ready to go pouch ready to go just in case anything happens. For home emergency kits it would be an awesome addition to have too. Just a thought, seeing as how places like in California there will be a mega flood and natural disasters are getting more and more brutal elsewhere on the world. THANK YOU ROB AND LUKE!!

Wood ash can be used for its significant amount of potasium oxide that when mixed with water will make potasium hydroxide. Then if you can use nickle and iron for a 1.2v Edison battery probably have to charge it, but they are known to be tolerant of overcharging. Iron is the negative plate and nickle is the positive plate. At 1.2v per cell, 5 cells in serries should give you a voltage of 6 volts to charge your cellphone.

Zink has a strong tendency to form dendrites that are easilly disturbed and may break off. So if you charge it and the dendrites break off.

[@kreynolds1123]

@@JJFX- during charging, it takes energy to plate the zink. If the fragile zing dendrites breaks it's no longer conducts electricity and the energy stored in the plated zink that's no longer part of the circuit becomes unavailable. It will eventually mix with the iodine again which could be replated, so the battery could be recharged many times. But I doubt the usefulness of trying to replace automotive lead acid batteries given the fragility. Maybe a gell electrolyte might work better.

What if you created a number of 'spines' of zinc facing downwards into a fish tank, a bunch of copper 'spines' coming up off of the bottom of the tank, fill it with water, iodine and potassium iodide, and then made it so the zinc spines could be raised and lowered into the tank? Would you get higher voltage and more amps or would the voltage stay the same just with increased amperage? Is it 1.2V per piece of zinc? Maybe use solid wires for the spines? Make 'em easy to replace as they corrode out?

I also wander if you made a screw thread lifting/extracting mechanism; via an Arduino, to halt the reaction and/or reduce the current and controlling the charging by partially removing the zinc rods to produce only a specific current that you are needing, e.g feeding another battery or super capacitor bank to run power

I will refund you 3 of those cents... He has already done so in other videos... Did you see those?

[@clivefrancis3546]

What about a silicate salt battery tutorial?

[@kevinroberts781]

How about a 55 gallon drum?

[@robtherub]

As you are a chemist would like to see the reaction diagrams. Zinc iodide is made?

[@RussellFletcher-v2g]

Rob,Hope you are well. I need you to get in touch with me. I’ve made perpetual motion

[@kennethjessop6073]

What is the purpose of the plastic layer?

[@j.m.hughes1810]

I would like to know what type of plastic it is, and also what purpose it serves.

[@ralphsammis7330]

That’s a new one “conductive plastic”?

[@ThinkingandTinkering]

oh ok

[@offgridwanabe]

easier than the concrete battery

[@captainnemo6655]

Different battery. This one is meant for when you are stuck in a survival situation... Concrete battery? That's for when the danger has passed

[@ricodegallo3060]

👍🏽

[@garygranato9164]

isnt it more of a generator considering you didnt have to charge it up. ?

[@rockjockchick]

Yes like the D or AA batteries you buy at the store.

[@josepeixoto3384]

sizes? numbers, volts, amps..?

[@adrianelliott5555]

What about the good old lemon battery a piece of zinc and copper jabbed in a lemon? I can't think of an easier battery than that. Yours maybe the easiest rechargeable battery though.

[@captainnemo6655]

I always thought about these batteries and Egyptian mummies!! Have you ever tried to keep the lemon as intact as possible for battery longevity? I had an idea to scrabble the insides of the lemon completely and then inject a bit of iodine salt to this lemon smoothie electrolyte and then stick a spike of copper and the other one.
