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. Gemma Haines reports.

  • Its not meant to replace a light bulb at night. It's to save using electricity during the day!

  • @abmac did you see electricity ran to any of those shanties? didnt think so. even if it was, do you think they could afford it? also the creation of jobs in impoverished communities is an amazing thing. the holes also appear to have been sealed, thus no leaks. go grab another footlong, or maybe buy some lightbulbs for someone living in the dark (including possibly yourself) ...

  • you can't save what you don't have

  • i c.. any transparent bleaching brand is ok..get the transparent clear bleach so that the water wont get murky..

  • hi, thanks 4 d suggestion.. will any detergent soap will do.. i belong to india.. so i think v don't get "zonrox" brand here.. v get "robin" brand bleach here..!!

  • this is just to save electricity during the peak hours of the day..

  • plastic sheet cant withstand the wear and tear from the sun and storms, not to mention falling debris also..and these families most of them dont buy new GI sheets.. they would rather buy 2nd hand GI sheets from the shop..

  • and that would cost how much? u have good idea.. but this is a lot cheaper...

  • a small plastic transparent window on the roof maybe an alternative but it will only have the light in one direction with out the water refraction. and besides, those people cannot afford to have a window built, and its a litle use to have windows on the wall coz light wont penetrate inside due to the fact that these houses are very close to each other, i mean very close...

  • if u cant afford the electricity bill, its much better to have atleast a bright day than having it dark both day n night.. anyway we r used to have candles or kerosene lamps during the night if we dont have electricity in the philippines ...

  • try zonrox brand... u know, the transparent liquid use to make clothes whiter?.. u use it with laundry soap..

  • it a good idea to.to put window on the roof.but the point here is to save money..they cannot afford to buy windows and put it on the roof hehehe ..
