What this video represents is personal learning and exploration. That's never "useless".
I have no hopes of replacing hundreds of years of battery research by individuals and corporations with more knowledge and resources that what I posses. So, please take your negative comment and shove it up your voltaic pile.
Well, hopefully you understand how useless this "research" is. For 45$ you can buy about 250 AAA 1.5 Volt Batteries, that will power your led a lifetime....And it would be nicer to take the energy from your energy company. Than you can power this 10mW device for 0.15$ a year...
While laundry detergent usually does not specifically name the exact chemicals; I
would suggest that it is the "brightening agents", i.e, sodium hypochlorite that is
the real electrolyte reaction you are seeing (bleach). Magnesium will always
oxidize somewhat in the presence of such; it's kind of like a "sacrificial anode" and get used up, and turn into magnesium oxide. Your surfaces will also have
a somewhat thin and non-conductive surface forming almost immediately.
@pyrolytic Right, they do develop a non-conductive coating within a few days! I've been trying various household (and industrial) chemicals looking for a good electrolyte that is active enough without being too corrosive of the magnesium. Diluted drain cleaner seems pretty good, but even with that I need to clean the plates every few days... Any suggestions? I also made some "dirt" batteries, and the dirt seems to keep the formation of the non-conductive layer to a minimum.
@harveyworks I'd suggest no cleaning whatsoever, and take a note of the current likely rising faster than when
it was "cleaned" prior. I think the reason is that as the magnesium gets somewhat oxidized/pitted, it actually creates more total surface area than when it was new. It may not look ~ nice then; but its probably more
efficient for it's energy use. When air dried out, some of oxide will flake and fall off anyway.
@JacobH420 , the amperage drops as the fabric dries out. It comes right back when I re-wet the pieces. Eventually, the magnesium will corrode away, but with a mild electrolyte like laundry detergent, I think that might be months or years. I've tried more active electrolytes like bleach, and hydrochloric acid, and they significant;y boost the amperage, but they also corrode the magnesium pretty quickly.
would using zinc and copper be better? or does your combination produce more voltage/amps?

@00imwagenvormir00 Youre an idiot and if everyone thought the way you did, we would have never made progress

Hello
You can use magnet...Instead of use saled water or vinegar (no corosion)
You can see iron phosphate lithium to use with salt water

@harveyworks try using two different electrolytes instead of two different materials for the anode and cathode them tell us your results please :-)

thats pretty cool , how long do they stay charged?
