A complete teardown and analysis of the Blackout Buddy H2O water powered flashlight. This is an emergency flashlight intended to have a very long shelf life, but activate when water is added.
Although this technology is often described as "water powered" in similar products, the water is merely rehydrating the dry electrolyte in a multi-call battery and as soon as it is added the battery electrodes start to change state as in normal cells. That means that after activation the battery will have a short active life before being depleted completely. In this case all the energy created is used to illuminate three LEDs taped in parallel across the two sides of the cell stack. Brightness will vary widely in use until gradually fading away.

LMAO, I knew you were tasting it(electrolyte), mad scientists usually do.
Bro What is the inside of salt water lamp and check the voltage and amps upload video bro
Warning on package: Do not disassemble. Do not eat the contents of the battery.
Bigclive: …
I wonder if they have this in the Air Cell Battery Version, If not then Lets Build it and Sell it to China..$$$$..
At school, way back in 1970, we used blotting paper for our separators. Our electrodes were old copper pennies and shillings. They needed to be minted before a particular year because the metals in them were important to the experiment. Our electrolyte was a saturated salt solution, if I remember correctly, and the main reason we conducted the experiment was because the old coinage was being withdrawn from circulation and the "New Pence" coins either, weren't as effective, or not effective at all.
We had an array of "Griffin & George" instruments to measure our success, or failure!
We did actually manage to light some small filament light bulbs, which I thought was most impressive! We tried to power a transistor radio at some point, but the pile couldn't develop enough sustainable current to make it effective, but we did get a few pops and crackles, with just a hint of "Radio 4".
i saw something somewhere about improvements you get with tiny fuzzy wuzzy surfaces. i forget now. you're welcome.
Torch.
My brain hurts!
I remember years ago I used to bite down on flat dubble and tripple a batteries to get extra life out of em. But I got older and battery casings got tougher so resorted to using a hammer.. lol
But it worked
I sympathize with you being tempted to taste it to figure out what it might be XD
so Clive , you tasting the electrolite made me remember back to my early 20's , someone decided to make my life slightly harder than it already was , and put in a complaint to the local constabulary dobbing me in for 'possession of drugs' . Well in all honesty I was and still am 45 years later a pot smoker (but nothing harder) . Anyway , this over zealous cop decided to open the freezer and examine the contents , he picked up a zip lock bag containing frozen brine shrimp , food for my aquarium full of tropical fish . So he opens the bag , breaks off a decent sized chunk of very rancid smelling frozen dead brine shrimp , placed it on his toungue and began masticating upon it ……………..I didnt have time to stop him , and wouldnt have anyway (lmao) and he looks at me and actually swallowed it and says and what do we have here then ????? so I said , it's fish food mate , you shouldnt actually eat it , of course he didnt believe me and was convinced it was some kind of nefarious illegal substance , so I asked if I might demonstrate , and took it to the aquarium and dropped some in starting the usual feeding frenzy of my ciclid population . I dont know if he ever learned his lesson not to put unknown substances in his gob , but there ya go , just thought I'd share a memory 🙂
When I was a kid I "took to bits" several zinc-carbon batteries. (The carbon rods were useful for electrolysis, for example.) The electrolyte as far as I can remember was mostly manganese dioxide, with perhaps a bit of ammonium chloride added. Mostly a black powder. No idea of the proportions though. Can you even buy those any more?
This i like! Thanks!
I remember demonstrating one of those coin, cardboard cells when I was in Primary school! Everyone in the class thought I was a wizard. Lol! Led to an obsession with science to this day, potato clocks and all.
Very Cool man!!
