Solar bottle light bulbs

As you know, there are countless uses for empty plastic bottles.

Here is another one to add to that ever-growing list: a solar-powered light bulb.

You can watch the YouTube video below to see how they are installing these solar-powered bulbs to houses in the Phillipines. If your Internet access doesn't permit you to watch the video, don't worry. I have taken screen shots and explained the process below.



This first picture shows the inside of a home in the Phillipines in the middle of the day. You couldn't tell the difference because it is so dark.



You take a piece of tin roofing and cut a hole to place the large bottle. You need to seal it in place.



Then you fill the bottles with water.



Put a bottle cap's worth of chlorine in the bottles.



Cut a hole in the roof for the bottle to fit into.


Place the bottle in the roof.


Let there be light.


Social entrepreneurs in the Philippines are turning solar-powered light bulb installation into small businesses. It does not require technical training, and all the materials are readily available.
