Solar Bottle Bulb

You may have previously heard or read this before. Due to its practicality, its cost, materials availability, the effect that is impacting our daily lives, I am delighted to spread this idea.

As those wise men keep saying, necessity is the mother of inventions. The electrical shortage and increasing cost of electricity, the solar bottle bulb technology was born in Brazil invented by Alfredo Poser in 2002, a mechanic worker looking for a way for a substitute to electricity light using bottles of water.

This simple idea, a solution to energy crisis took many years before it was realized, implemented and spread to the world and at last, it's here in the Philippines. A Liter of Light (Isang Litrong Liwanag), proposes an alternative solution for household electricity dependence and open flame fire hazards using the natural source of light - The Sun.

The lightning project will use the solar bottle bulbs made from recyclables 1.5 Liter PET bottles, filtered water, chlorine and salt. This will cost approximately P50 to make 1 piece and will save at least P500 monthly electric bill. It will also save our planet earth from global warming, preventing climate change. 1 solar bulb would save 17 kg of carbon dioxide in a year. Imagine a millions solar bottles installed in household throughout our country and the whole world.

A Liter of Light is the latest project venture by MyShelter Foundation established by Illac Diaz to create a system of sustainability and reliability through its capability building and employment generating projects. The project aims to light a millions homes in dispriveledge communities nationwide in 2012.


Philippines Guinness World Record for Most Solar Bulbs installed in a day

Last Nov 30,  11,300 solar bulbs was installed by Rotary Club District 3380 and Armed Forces of the Philippines (AFP) in low income communities in Metro Manila to break world record for the the most installed solar bulb in 1 day set by Brazil which is 3000. Continuing for the project, 100,000 will be installed in Cebu this December and another 107, 000 solar bulbs early next year which marks 107th anniversary of Rotary Club District.


How to Make a Solar Bottle Bulb

To make a Solar Bottle Bulb, you need a 1.5 Liter PET bottles, flat or corrugated metal roof, filtered water, chlorine, salt and sealant. This simple lighting technology is very easy to make. Just follow the simple steps below.


Cut a circular Hole in the metal roof, approximately less than the diameter of your 1.5 Liter Soda bottle. Make a small strips perpendicular to the hole for a better grip of sealant and the container.


Insert the 1.5L soda bottle to the metal roof up to 1/3 of  its body and apply sealant around the metal strips. Let it dry.


Filled with filtered water. Water should be free from contamination to be able to reflect light perfectly. Put chlorine to resist the growth of algae, moss or any microorganisms.


Installed in your roof. Apply sealant for waterproofing.


Solar Bottle Bulb works by refraction of light rays because of different medium, air and water. By refracting light from the sun, it produces light 360 degrees around the room with equivalent light power of 60 watts bulb. It will last for 5 years without maintenance and before the water has to be changed. The chlorine prevent the growth of microorganism and maintain the clarity of the water.
