Picture of How to build a SOLAR BOTTLE BULB

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)

Dear

I have tried the same but It's not work. may I was wrongly do the procedure from filling water + bleaching powder. I want to know more descriptive information i.e. how much water and bleaching powder required and how much time it will keep in sunlight. (i.e. quantity, time required)

is any gas is generated in the solution ? questions are created while bleaching powder is mix in water

in anticipation

If you are in a temperate climate where freezing during the winter months may be a problem {tool sheds, garages, & etc.}, DON'T use water as you medium. To avoid the medium from freezing, JUST use an edible grade of mineral oil (~$5.00/Liter) as your medium! It has a freezing point of -20 degrees F or -30 degrees C. The refraction of the light would not be much different!!

I would add some salt and alcohol too, if it freezes the bottle will suffer less forces because the water will not freeze which results in ice; ice has a lower density than water so the volume will go up, stress on bottle where the bottle is inside the roof-panels. Adding fluorescent components wiil make it glow a little, not enough to see what you would be doing but maybe nice as an orientation light. These kind of bottle lights can also be placed in a wall, I saw it in one of the Transformer movies near the Pyramids where megan and shia hide and are found by a bug-transformer, these look more like glass wine bottles glued in a cement wall, looks pretty cool too!

Great how/where can l get bleach. My email jopeyemi60@yahoo.com or stanleyboy39@yahoo.com pls help me

You can ALSO use some finely cut up pieces (1-2 oz.) of copper wire placed in the solution if you absolutely don't have access to any liquid chlorine bleach!

Another substitute is 15 ml of an Iodine Solution instead of chlorine bleach may be used. Iodine can be found on most medical shelves in many types of stores!!

Both of these things can help to prevent the growth of algae in any water in the bottle!!!

Clorox

will indirect solar radiation be enough to light the bottle? for instance could this technique be used to light a room without a window by placing the bottle in the wall between the rooms?

can you use it as a amplify for lights???

will it work at night

Not without a light source to shine on the bottle, which kind of defeats the purpose

As for the bleach - is it hypochlorous acid or hydrogen peroxide?

The only purpose of the bleach is to keep algae and other fungi from growing in the water over time

whether it will still be lit if I put it in the garden? with poles for example, as a replacement for garden lights?

It won't work in the dark.

What will work is a battery operated headlamp around the clear bottle of water. Light facing the water. Try a clear milk jug for even more light. The water "magnifies" the light.

will it work at night???????? Upto how much time a bottle will go????? any thoughts.......

It is run by sunshine. If it is dark outside, it won't light your room.

it does not work at night. (unless you got streetlights outside though the resulting lumination would be really dim compared to that of at day) and it only refracts sun light.

I doubt very much that street lights would produce enough light to penetrate the bottle.

Obviously it doesn't work without natural light. It's the light outside that shines through the water in the bottle that creates the light. The bottle will work endlessly unless it's broken.

This is being done in South Africa where it is very successful as there is abundant sunshine.

if it has solar panel and battery, it can be used at night, and even can charger small device like phone ,mp3 etc
optional: remote control, usb port ,
let bring light to life .

Where can i find a plastic tube? Ive been looking everywhere for something similar to old film containers but havent found anything similar. Any advice?

Buy Coke or Sprite 1.5L.

Are you going to be traveling to Taos soon? I am not sure if I am asking the right person :-)

I don't think you need anyone to travel to Taos. You can simply make it yourself with an empty clear plastic bottle or container.
