Light up dark areas in your home during daytime using this green and sustainable concept. Recycle used clear plastic soda bottles, add water+bleach, then install. After installation this solar light bulb can provide approximately 55 watts of light from the sun! 

The comments below have noted that this is like a solar tube or deck prism. 

The communities who benefit from this idea live in areas where the houses hardly have windows and live in darkness even during daytime. Their solution up until this innovation was to turn on the light bulb and use electricity.

Materials:
*PET soda bottle
*Galvanized Iron (GI) sheet
*Rubber sealant
*Bleach
*Filtered Water

Step 1: Cut approximately 9 x 10 inches of GI sheet (corrugated or flat)

(Filipino: Gumupit ng yero na may sukat na 9 x 10 inches.)


*Here is a how-to video
<p>How do they make this thing work at night though? In the video I saw at literoflight.org the people have a tube like thing in the bottle with something giving off the light, and there has to be something retaining the energy during the day. This would be a great science fair project! Anybody know how to do this? There is more to it than just the bottle, water, bleach, holes, rivets and sealants. They are using these at night.</p>
<p>The literoflite ones use a small solar panel to charge up a battery which then powers the bulb at nite.</p><p>If you look carefully you can see the water level at the halfway mark, so they are using water as a light diffuser. The tube bit is most likely insulating the bulb wires that run down in the water to stop corrosion which could change the water clarity.</p><p>This version is a daytime only one with no batteries, solar panels or bulbs.</p><p>Just in case you were still wondering. :)</p>
Can we use bleaching powder in it !
<p>Although I'm, let's say disappointed with the lack of understanding in the comment about crowd funding, I have always loved this idea. However, It does need some improvement. In Australia the sun will cause the plastic to perish in a single summer. Glass would be a better option, as would a clear liquid that ISN'T prone to grow algae. I have wanted to install some of these in our sheds, but I also have experience with a Solatube, and find that to be a much better option. Now if someone could find a way to use that technology adapting it to re-use of materials, THAT would be brilliant. Crowd funding is not something to blow ones nose at! It has been used by some greedy self important jerks true,as is anything that they can jump on to try to accumulate &quot;points&quot;... but it has also helped others with ideas that DO seek to make products that HELP the poor, the disabled, etc.. People should not be put off the idea of crowd funding simply because of a few with bad intentions. People should be encouraged to think about the need for the product, and do so without greed being the motivation for investing. Invest to make this world a better place for everyone. THAT is the reason for crowd funding my friends.</p>
You do know that bleach kills algae, right? Also, a certain type of plasticbottle must be used. That is because itlasts longer. I believe that this video will help you: https://youtu.be/i5YQ4t5apPM
<p>what is Solatube?</p>
<p>Google it?</p>
<p>What is Google?</p>
<p>Here you will find some information:</p><p>http://lmgtfy.com/?q=Solatube</p>
<p>Is it worthy? How much investment need for that?</p>
<p>I think it is wonderful that people are exercising their initiative in helping themselves. Why would I want to hinder that by contributing? People beg Jesus for miracles; beggars beg for money; neighbors ask questions instead of looking things up. If the boy scout troop wants to go to Hawaii, that's great! Go! Why are they going around asking people to get them there? </p>
<p>What are you talking about?</p>
lol right!?
<p>Saw a documentery about this on tV about four years ago, the idea has been around for quite some time and has been used all over Africa and South America, as well as Malasia.</p>
<p>Just a question: what if I don't have a Bosch lithium-ion cordless drill?</p>
<p>Just a quesstion: Why are you being a jerk?</p>

<p>This a very thought provoking instructable.... How would glycerin behave, a little oil? So many more avenues for inquiry. Thanks for the challenges. </p>
<p>beutiful project </p><p>I want to help them there if i get the change</p>
<p>Awesome Project....</p>
<p>this plastic bottle light is a remake on a centuries old idea used to illuminate the interiors of darks boats. they are called deck prisms. </p><p>see: <a href="https://en.wikipedia.org/wiki/Deck_prism" rel="nofollow"> https://en.wikipedia.org/wiki/Deck_prism</a></p><p>still its nice idea.</p>
<p>What if you use a glass coca cola bottle, with its curvy form. Will it work the same?</p>
What kind of bleach are gonna put in ? Just like commercial bleach?
<p>cool but this soda solar bottle bulb doesnt work on dark night. Moonlight maybe dont now. </p>
<p>Can not work at night .....no Sun</p>
<p>1 ) Chlorine in bleach is to prevent water going green from Algae.</p><p>2 ) Can not work at night .....no Sun </p>
<p>Great for desert areas... Not direct sunlight, yet you are lighted up with shelter... If you need... Then just grab your AC and just live your life out.</p>
<p>LOL if you had AC, you could just plug in a flourecent light bulb...</p>
<p>Hm... Can you do this without busting your roof open? Maybe... Place them on windows? Except it won't work at noon... Then, another amazing thought... What if people wayyyy back then could do this, and they could have made a clock out of it? like... think... If it went dark in the room, it was noon. If it was bright on one window, it was morning, on the other, evening... Then when it was dark altogether, then it was night.</p>
<p>Amazing idea. Free. Unlinke the Crowdfunding ideas which seek a millions to fund the development of a product the poor cannot afford.</p><p>This won't work under many non-solar conditions but when it does work it must be a miracle for these folks.</p><p>Now if the liquid could be made to store the light similar to fireflies and fish...</p><p>Have you tried using longer tubes, for instance an eight foot tall pipe in the corner of a room? Or a long clear plastic pipe and maybe diffuse its surface? Plastic fiber tubes are used to transfer light from one end to the other.</p>
<p>AMAZING! WHAT A GREAT PERSON THIS IS!!!!!!</p>
<p>My grandfather used this trick to light a work area in his barn when I was a kid. </p>
