I maintain Edison batteries. The voltage comes from the chemical reaction of the batteries. The amp capacity comes from the surface area of the electrodes in the salt bridge solution and the distance between the electrodes. Battery manufacturers use a mesh like electrodes to increase the amp capacity and size. Deep cycle NiCd, FeLiPO4, and FeNi use a a lattice framework layered with powdered Ni and Cd. The powder increases the surface area for each plate. There are some Edison batteries that have been in service for about a hundred years. My batteries' age are about forty and fifty years.

You could have made a lead acid battery from technology over 1,000 years ago. Galena and sulfur and glass to make the whole thing.

You can certainly make a lead-acid battery but those are rechargeable so you'd still have the same predicament. AFAIK if you start with lead plates the battery would be fully discharged.

[@johnbrizendine7716]

@@eDoc2020 They will actually have a bit of voltage on them, and if the lead is oxidized to begin with(only the positive plate/anode should be oxidized lead), it will react with the battery acid and be anywhere from 20% to 60% charged just from being built.

I am immediately wondering how one would be able to test the voltage or the battery? Assuming advanced tech and knowing the voltage (and amps, ect) that it would require, how could you test that in the same rudimentary way you are creating the battery? Other than not overcharging or undercharging, how would you know you got it?

[@PrebleStreetRecords]

Look up the “electroscope”, a very early means of detecting and measuring charge.

[@PixlRainbow]

early voltmeters are made with a very high resistance resistor attached to an extremely sensitive galvanometer. A galvanometer is constructed like a motor, except that it only has a single coil/pole and it contains a spring that pulls it out of alignment. Applying voltage causes current to flow, which causes the galvanometer to pull against the spring. As the tension force of a spring is directly proportional to the elongation of the spring, the angle where the galvanometer stops rotating indicates the amount of force the galvanometer is applying, which is proportional to the amount of current flowing through the coils. As the current is directly proportional to voltage, this gives you an indication of the voltage. To avoid draining so much current that the voltage sags from battery internal resistance, the whole system is calibrated to run with very very little current.

[@ElliotKrueger]

@@PixlRainbow It might be interesting for us to attempt to construct one of these. I don't mind my current method though, of just "tasting" the electricity 🙂.

So I understand that the video is about making a battery, which was very fascinating, however, based on the title, would it not be easier to make a generator, powered by a water wheel? Oddly enought the exact premise is something I have thought about (going back in time and needing to charge my phone), and I always figured that a geneartor would be easier to create/source material for then the chemicals for a battery. Basically, magnets and copper wire. I'm not an engineer, so maybe its more difficult?

[@PixlRainbow]

the magnets?

[@ElliotKrueger]

I think this is something we're definitely wanting to do. However, one of the major setbacks is how to produce permanent magnets of a significant strength. From what I understand, natural loadstone magnets are pretty weak, and making stronger ones typically requires pulses of electricity at a very high current. Additionally, you'll want to produce a lot of very thin wire, which from our experience, is pretty laborious. I don't think any of this is outside the realm of possibility though!

[@JPRTonundFilmstudio]

​@@ElliotKruegerisn't it feasible to generate electricity by having a small battery serving as a "starting magnetic field" and the generated current in part to amplifying the magnetic fields further. I thought that car alternators partially work like that. When you spin then you don't feel the axle locking that you feel when spinning a permanent magnet motor. I am not an expert though...

You don't need to go back 100 years to be amazed. 1995 me would have been absolutely blown away by even budget smart phones we have today.

The fact that the device would have been the most powerful computer on the planet and fit in your pocket would have been equally impressive. The largest problem to taking a cell phone back in time is the fact that almost everything relies upon constant internet/cellualr. There was no 3 or 4G (forget 5G), no wifi, and no USB on computers means you have no way to do much (except what is already downloaded on the phone) even if you could charge the thing.

The irony of the comment (12:18) of how simple telecommunications starts and where it is today, modern communications uses a digital signal (either on or off) and the old simple telegraph uses a digital signal (either on or off), it is just the encoding of the signal that has changed. The modern system uses a fixed byte size and standardises the signal, where as the 'old tech' used a variable byte size with an 'end' signal, thus minimising the 'dead' time in the transmission (when no data was being sent, just empty bits), example on Morse code 0 (zero), which has the longest signal in Morse code (5 dashes) is a 23 bit byte (1110111011101110111000), but e is only a 4 bit byte (1000), both having the 000 as the 'end signal' to show the end of the byte, thus saving 19 bits of bandwidth for use on the next byte (or more). Funny how sometimes 'old technology' is often more advanced than the 'new technology' as the old timers had to make more efficient use of the available resources (in this case the 'bandwidth' available).

Verry nice project! Now i have a good intuition on how much more energy dense these lithium batteries are. Copper, sulfur and zinc are all non toxic, right? (unlike lead acid batteries)

[@05Matz]

They're... not _non_ toxic (I know copper compounds in particular are dangerous for fish and other aquatic organisms), but they're things I'd be much happier working with than lead. I'm certainly no chemical expert though. AFAIK, all three should be only 'temporary' poisons that clear from your system over time if a little bit of contamination gets in. Lead sticks around mostly for life. Some of those compounds might be harmful just because their PH would burn you, though? Lead acid batteries are full of... well, strong acid though. that would DEFINITELY burn you. So these batteries are almost certainly much safer, I would think. Modern lead acid batteries are pretty good at keeping both the lead and the acid far away from you, though.

[@ahveganpizzabella]

Zinc fumes are sadly very toxic when you melt the zinc especially, giving terrible zinc poisoning and zinc disease similar to lead poisoning. Sulphur is highly damaging to lungs esp the burning fumes of it, or acid fumes, and kills the liver when ingested. Copper is less toxic but it will accumulate in your body organs like eyes, liver etc over time if u work with it unprotected and taste the wires and breathe in fumes from the acid solutions like they do

With Android, we found that you only need the power and ground leads to charge it. However, with iPhones, you would need a total of 4 wires, two of which for power and ground, and two of which for data and ground. You'd then have to supply two different voltages, with the data being 3v in order to signal the phone that it's okay to accept a charge. It took some experimentation for us to get this to work, and I may have destroyed more than one of HTME's iPhone chargers figuring this out. 🙂
