low-cost light tube using bottel , water & sunlight



Hunter's comment

Liter of Light is a global, grassroots movement that uses inexpensive, readily available materials to provide high quality solar lighting to people with limited or no access to electricity.
The Liter of Light is both a day and night solution that provides passive daylight as well as solar nightlights such as lanterns, house lights, and streetlights. The solar bottle bulb is a simple device consisting of a 1.5–2 litre plastic bottle filled with water plus a little bleach to inhibit algal growth and fitted into a hole in a roof to refract sunlight. The device functions like a deck prism: during daytime the water inside the bottle refracts sunlight, delivering about as much light as a 40–60 watt incandescent bulb to the inside of the house. One solar bottle bulb helps prevent carbon emissions of up to 200 kilos and can keep working for as long as five years

Donate them for making this word more colourful to peoples who are in dark......

Thanks for updated information.

For sure these kinds of projects should be donated. They are really important for energy sources. I hope it will be successful. Thanks for sharing.

WOW What an innovative idea it is? I'm shocked that what a creativity in this bottle. Really, technology is growing day by day rapidly. Solar Lights are now in trending everywhere. It is a very good way to use Sun Energy instead of Expensive Electricity.
