Solar Bottle Bulb (Part II)

September 17th, 2011 by Zachary Shahan

I covered this technique for bringing good light to homes using plastic soda bottles and water awhile back. But the technique has been getting more attention and Priti Ambani of our sister site Ecopreneurist has written about it in more depth, and found a good new video showing how to install the lights and calling for support to help spread the word via MyShelter Foundation Inc.’s “Isang Litrong Liwanag” (or “A Liter of Light”) Project. Check out Priti’s piece here:

I’ve been trying the technique with coke bottles and clorox but no results so far.I must be doing something wrong as I tried numerous dilutions.I’d love to use them for pathway lights if I can get some advice on how to make it work.I am using rain water,but that’s all I have.

$2-3 per bulb? Why so much? A free bottle, free or very cheap water, a tiny amount of bleach and sealer.
