Working Air Battery

[markdansie]

Hi,
This is a great thread. Great video's
It will be interesing to see how long they last.

Here is a link to a commecial battery using similar principles. Unfortunately they can only be used a few times.

They were released in Japan in 2007

Kind Regards

@lasersaber
Thanks for your video, it was great.
I have one question.
You copper wire, how far did you drill down into the rod? would there be any advantage in drilling further down and say use a rod to increase the surface area? Just thinking aloud.
I posted a couple of links on the Nopopo battery. Unfortunately they cost a fortune ($15 each) and only last once filled four ties. I am really interested in your battery the key will be how long it will last. I gather the magnesium is the only thing that will corode and it should be easy enough to wind another ribbon on to recondition the battery with time.
Many thanks and great work
Mark

Hello Everyone,
I've been following everyone's work for a while, especially the work on the JT circuit and these Air Batteries by Lasersaber. Well i figured it's time i began to contribute some myself. I rewound some Air Batteries today using Lasersaber's newest video and got pretty good results, but still no significant current from just the moisture in the air. (I live in Southern CA by the way so there's not much moisture in the air in the summer.  ) By adding a few drops of water i was able to light just about any LED or small set of LEDs to full brightness. That's a lot better considering that before i literally had to soak the Air Batteries to get this amount of current. So now i have redone the Batteries only this time i decided to add a bit of baking soda to the mixture instead of just salt, and it got me a good jump in current. I was able to light some LEDs off humidity this time around, and by wiring two together and adding about a ML of water to each I was able to light a fluorescent using a Jeanna's Light JT circuit. So I thought that was pretty neat and i will leave you guys with a picture to go with this, and keep up the good work everyone.

How long will this run continously?
