Bottle light can help conserve energy, prevent fire

Thursday, 24 February 2011

MANILA, Philippines – Residents of Barangay San Vicente in San Pedro, Laguna wholeheartedly embraced the innovation introduced to them by My Shelter Foundation, a nongovernment organization, on Wednesday afternoon.

It is called the “bottle light”, so called because it is made of an empty 1.5-liter soft drink bottle that can be made a source of light.

It is a cheaper alternative to other light sources because all one has to do is to install it on the roof. The bottle light will then absorb the sunlight and will scatter it inside the house.

“Usually ‘yung mga nagkakasunog kasi gumagamit ng kandila. Marami ang namumuhay sa dilim,” said Illac Diaz of My Shelter Foundation.

The said barangay is the first in the country and even in Asia to use the bottle lights in homes. Four hundred homes were lighted at the project launch on Wednesday.

“Dati natisod ako.. Ang sakit na nga ng paa ko.. Buti na lamang may ganito,” said Aling Lucia, one of the homeowners who tried out the bottle light.

Studies have shown that one can save by using the bottle light instead of a light bulb during daytime.

“Ayon sa Meralco, P70-80 ang mase-save kung one month ‘di gagamitin ang bombilya,” said Vice Mayor Novic Solidum.

Illac Diaz of My Shelter Foundation explains how to make the bottle light.
One will only spend P150 per bottle light and making one is easy:

Fill a 1.5-liter clear soft drink bottle with purified water as tap water will produce moss in the future.

Add 3 tablespoons of liquid bleach.

Tightly seal the cap.

Make a hole in the roof and insert the bottom part of the bottle leaving it exposed under the sunlight.

Seal roof with sealant to prevent raindrops from getting inside the house.

The group is hoping that what they have started will be replicated in the entire country so no Filipino will ever live in a dark home again.

Meanwhile, Diaz asked everyone to donate, instead of throw away, their empty soft drink bottles so they may provide more bottle lights to other depressed areas in the country.
