Just a little interesting knowledge here I learned when in the Philippines: Did you know if a regular battery (not rechargeable) is very weak, not dead, you can boil it in hot water for 2-3 minutes...and you'll get about another 1/2 to 1 hour of full power? It loosens up and excites the electrolites. This is lifesaving knowledge in an emergency. Perhaps auto companies could cook their batteries by thermally insulating them to squeeze more mileage out of an electric?

Anyway...high 5's to Japan; that's quite an achievement!]]>Jan 15th 2009 1:21PMhttp://www.switched.com/2009/01/15/nopopo-batteries-last-10-years-thanks-to-urine-and-beer/http://www.switched.com/2009/01/15/nopopo-batteries-last-10-years-thanks-to-urine-and-beer/Jan 15th 2009 2:32PMhttp://www.switched.com/2009/01/15/nopopo-batteries-last-10-years-thanks-to-urine-and-beer/http://www.switched.com/2009/01/15/nopopo-batteries-last-10-years-thanks-to-urine-and-beer/wasteful...but in some 3rd world countries...a battery store isn''t
always around the corner, or if you are deep in the woods. The joules
wasted are not even in the equation if it's an emergency. The idea is
to USE the battery because you don't have a replacement.

BTW - if you have a magnifying glass (with rotation and a glove) and
a bright sun, or a small torch, you might get similar but not as
efficient results. Peeling the label 1st is advised to avoid embers.
Natch, a red hot battery will not only will ruin the device, but the
electrolites inside may dry and clot, rendering your experiment into
overkill. Boiling is your 1st choice. Why 2-3 minutes? Just long
enough to HEAT the battery, not render it soggy or spring a leak.

What if you don't HAVE a good battery at all...and you're out in the
bush??? Look for citrus fruit or acidics...either in your supplies or on a tree if in a warm climate. A simple lemon can output 1.5 volts with the
right bi metal electrodes. The very best is the grapefruit, with high
acid content. Milliamps are as good as any AA battery. Also try starch, like in potatos or carrots, and salt water.]]>Jan 15th 2009 3:55PMhttp://www.switched.com/2009/01/15/nopopo-batteries-last-10-years-thanks-to-urine-and-beer/http://www.switched.com/2009/01/15/nopopo-batteries-last-10-years-thanks-to-urine-and-beer/Jan 15th 2009 3:58PMhttp://www.switched.com/2009/01/15/nopopo-batteries-last-10-years-thanks-to-urine-and-beer/http://www.switched.com/2009/01/15/nopopo-batteries-last-10-years-thanks-to-urine-and-beer/
I'd buy a couple.]]>Jan 15th 2009 5:55PM
