Bottles of water provide light inside housing of the poor

July 11 - A bottled liter of water with a few teaspoons of bleach is proving to be a successful recipe for dwellers in the light-deprived slums of the Philippines. The simple technology is spreading sunlight in places where it has never been, and saving residents money at the same time

That's pretty awesome and clever thinking. A good way of putting western plastic trash to good use in the third world. Imagine the difference this sort of thing would have made even in the western world if people could easily make a plastic container a century or two ago.

yep. Thats a step up from the homeless ppl using computers with only 4gb ram.


but seriously, when its daylight outside you can open up a window or door. Havent these ppl ever heard of candles or glow-sticks? what a stupid thing to do...................



just kidding. Its pretty cool!

I know you are just kidding, but these people don't have a window they can open. Let alone a glow stick Candles pollute the air and give off very little light for the amount of energy they consume.

This sort of thing could be used in a refined form in the west too. Light tanks in the roof. Especially in small offices where workers spend their day indoors.

It's a neat discovery. I'm surprised it's taken people up until now to figure it out.
