No one really associates a plastic bottle with a lighting bulb. However, Isang Litrong Liwanag (“A Liter of Light”) a Philippines based-program aims in bringing free indoor lighting to some of the country poorest residents.
This is simple, cheap, and unbelievably effective idea. This is brilliant. I am amazed. A simple innovation – using water, bleach, one liter soft drink plastic bottle, and some epoxy, sealed into the roof becomes a natural solar light bulb. Once it’s all done the refracted light is powerful enough to brighten up home.
Take a moment to watch the resourcefulness and innovation of a Pinoy. Love this nice mini-docu. The video says it all, and you’ll be surprised at how bright the “bulb” is.
I hope this A Liter of Light campaign will reach those remote areas which lacks or does not have access or supply of electricity.
