SOLAR LIGHT BOTTLES - how does it work?

[vincedin]

---

A solar bottle light bulb, an innovation introduced in the Philippines by Illac Diaz of MyShelter Foundation, as a cheap alternative to other light sources. It was an ingenious invention by an engineer in Brazil. It is called “bottle bulb” because it is made of an empty 1.5 liter soda bottle and in it is a liquid bleach and purified water that can be used as an alternative electric powered light bulb. However, it is only useful during daytime but its luminance was tested and shown to produce as much light as a 50W incandescent bulb.

How to make your own Solar Bottle Light Bulb?

The materials are the following: 1.5 liter soda bottle, 1’x1’ roof sheet material, purified water, camera film dispenser, chlorine and a rubber sealant.

Procedure:

Step 1. Fill the 1.5 liter clear soda bottle with purified water then add 3 tablespoons of liquid bleach and tightly seal the cap. Do not use tap water because this will allow the growth of moss.

Step 2. Make a hole in the 1’x1’ roof sheet material, just the same size of the bottle’s circumference and insert the bottom part of the bottle leaving it exposed under the sunlight.

Step 3. Next, make another hole on the roof of the house (same as the bottle’s circumference) where you want to put the solar bulb and firmly fix the device.

Step 4. Seal the roof with a sealant to prevent raindrops from getting inside the house. It will produce a light when the water inside the bottle bulb refracts and scatters the light inside the house.

The solar bulb is expected to last up to two years before it needs changing.

Gihimo ni siya nga project primarily para sa mga kabos--sige daw, adto sa squatter or slum area, tan-awa ang mga balay didto if naa ba'y space for windows...wala. Mao nga gihimo ni nga idea so that the oppressed people of the slums can liberate themselves from IGNORANCE by READING. The light coming from these bottles can effectively provide enough light for reading, para sad ang mga bata from these slum areas can read, study, learn, and thus find ways to liberate these oppressed people from their condition.

wala man cguro ni gi design pra sa inyohang balay..pra man cguro ni sa mga balay na ngit2x or limit ra au ang light mosulod inig ka butang..

tungod man siguro sa tubig mao ni kusog ang light

Both water and shape of the bottle contribute the propagation of light from the hole in the roof into the interior of the house, via the process known as refraction, and a bit of light amplification through magnification is at work too.
