Bottle Lighting, a Liter of Light

The bright idea of bottle lighting, from the Philippine project “A liter of light” (Isang Litrong Liwanag) brightens up the life of ten thousands of poor people in the Philippines and will spread out to other, especially tropical countries for sure. The idea is very easy, but effective and inexpensive. Used plastic bottles, which would end up as garbage, are filled with filtered water and a bit of chlorine (bleach) to create not just an energy saving light, this lamp doesn`t need any electric energy at all, just only the sun. The bottle lighting has just to be inserted in the roof and sealed properly against rain water. There are already more than 15.000 lighting bottles installed in the Philippines and brighten the life of the very poor. Another postive side effect is the prevention of fire hazards in poor areas, caused by bad and often illegal electrical connections and easily-flammable materials. The very simple idea of the bottle lighting has been invented by students of the Massachusetts Institute of Technology (MIT).

The man behind the “A liter of light” (Isang Litrong Liwanag) project, the Pinoy entrepreneur Illac Diaz, has great plans. One of his goals is to install a 100.000 solar light bulbs in the second-biggest city of the Philipines, Cebu. Now, due to the high demand, inmates of a prison in Manila assembling bottle lighting sets and got a reasonable engagement for the benefit of their very poor compatriots. Illac Diaz claims that every solar light bulb, compared with an electric light bulb, saves 17 kg of carbon dioxide, one of the gases that causes global warming.
