WW2 American H20 batteries wanted

[31337]

My teacher told me about a batterie that can charge up just by trowing it in the water. He uses it every week since he got it and it still works! He sais the americans left those behind during ww2. When charged up it can make a bulb light up for 3 days in a row, battery is low? ==> trow it in the water again.

to be short ==> i want one :D
where can i find it?
i dont even know the name of that thing :oops:

OK............

stop ignoring me :bash:

euhm
if you guys dont know where to find it, can you guys tell me where i get a good change finding it? :(

Try Atlantis.

First time i hear about them, for sure they are not eternal but hell it would be cool if that would be at least partialy true....

A picture tells a thousand words, i think your teacher was having a lend of you mate. ;)

The only thing like this that I can find is an aluminum air battery (or cell).


Aluminum / air cells have also been made for marine applications. These are "rechargeable" by replacing the seawater electrolyte until the aluminum is exhausted, then replacing the aluminum. Some cells that are open to seawater have also been researched. Since salt water solutions tend to passivate the aluminum, pumping the electrolyte back and forth along the cell surface has been successful. For those cells that don't need to use ocean water, an electrolyte of KCL and KF solutions is used.

# Aluminum-air : long shelf-life and high energy density vs complex and low efficiency. Aluminum-air batteries obtain their energy from the interaction of aluminum with air. The incoming air must be filtered, scrubbed of CO2, and dehumidified; the water and electrolyte must be pumped and maintained within a narrow temperature range - hence the complexity of the battery. The batteries are not electrically recharged but are "refueled" by replacing the aluminum anodes and the water supply.

I found some mention of these type of batteries being used on WWII subs, in torpedos. When I first read your post I thought Atlantis and tinfoil hats too. But it does seem that this type of battery exists.

How practical, where to get? Dunno. Just found some pointers for you.

:bow:
thx for the info mate
SEEEEEEEEEEEEEEEEEEEEEEEE, ITS TRUE!!!!!!!!!!!!!!!!!!!!!!!!!!!
that will teach you guys :p

I stand corrected :)

How big are they physically? Since you have to replace them with sea-water i don't suppose they'd end up as a replacement for the AA ;)

it worked on normal water, not salt water
it was as big as a PC power-suply
