I'm currently putting together a bag that I can just grab and get out of town for a day or so. Came across an interesting article about a newly developed type of battery that's rechargeable in water. Did a bit more digging and found out about NoPoPo (No Pollution Power).

Developed by the Japanese in response to their power going out a couple of times a year, it runs off any water-based liquid.

Made by Nakabayashi, the AA battery can be charged by dropping it into a glass of water, juice or beer (no thanks) or even by feeding it saliva using a pipette. It's rechargeable up to 5 times and has a shelf life of 20 years!. According to the manufacturer, it's capable of running an LED flashlight for 5 hours.

Given the usual BS that goes with the whole advertising process, even if as a back up I can get 2-3 hours of power, that'll do me.

A set of 3 costs about $8, I assume plus delivery. Which sounds fair.

Anyway, just thought I'd put it out there. These things will definitely find their way into my backpack as an emergency sourch of power.

Anybody out there heard of these or have seen them work?

I havn't heard of these before...interesting. Sound like a good kit item IMO.
 
If it works, I'd be all for it. Interested on hearing any reviews that may pop up.
 
They've been around for years in one revision or another. There was a big fuss made about them being able to be powered by water, beer, urine and so on. I gather the more recent revisions are just a dump in water effort rather than using a supplied pipette. There's a lone review on Amazon UK that stops short of saying “con”because they actually do something, but folks might want to read the rest. There's video on YouTube too.............My take on it is that they are rubbish. I doubt I'd get 5 good charges even if they did work as advertised. Add to that the power output is feeble. Stressed is that they are for powering portable radio or LED torches. I suspect that was for the type of LED torch that some wrist watches could power. One of the gadget show type reviews I saw cooed over it because it powered up a remote control. W00T, back in the day remote controls were the last place batteries went to live before the bin when they were to knackered to power anything else.
 
That may be right. They may not be worth the investment, particularly in a survival situation. From the reviews I've read on the net, the newest form of the batteries which incorporate better technology might not be the same POS.

I'll check them out. If they're any good, I'll report back.
