Have you ever thought what you can do for the villagers? For those that would rather live in dark than to pay for the unreasonable electricity bills issued by the government? 

We take for granted our electric lights, windows and skylights to access the sun’s glow, but for those living in close-together shacks with corrugated-metal roofs, a stray ray is welcome, and something that can spread light to the darkest interior corners can be a dream come true.

Personally, I’ve been to a village in Chiang Rai, saw how they survive in such dark houses and even experienced it. Their kitchen, toilet, provision shop,etc were all kinda dark in the morning. I believe it caused lots of inconvenience to them though they are already used to it alr. 

So my friends and i planned to make a trip back and help them to build this solar lamps in their houses:) 

Hopefully the project is successful! Hopefully we can visit more village to build this too! This really save lots of their money i guess?  

The physics of the concept are straightforward: the bottles are placed in roofs – half outside, half inside – and their lower portions refract light like 60-Watt light bulb but without the need for a power source. A few drops of bleach serve to keep the water clear, clean and germ-free for years to come.
