Information Madness

In the age of cell phones and iPads, we forget the basic engineering and technology. We are so used to the electricity that when power goes, we fumble around for the torch (which again uses batteries). Here is a really simple genius solution to create 50 watts of Solar Lamp with just empty Soda bottle, water and chlorine.

MyShelter Foundation, an NGO in Philippines is bringing lights to the people who are living in darkness with just 2 Liter Soda bottle, Water and Chlorine.  Isang Litrong Liwanag (A Liter of Light), is a sustainable lighting project which aims to bring the eco-friendly Solar Bottle Bulb to disprivileged communities nationwide. Designed and developed by students from the Massachusetts Institute of Technology (MIT), the Solar Bottle Bulb is based on the principles.

I am pretty sure many Indians can also utilize this and use the power of Solar to build this Soda Bottle Solar Lamp. Here are the steps to create your on Soda Bottle Solar Lamp.

The needed materials are: 1.5 liter soda bottle, 1’x 1’ roof sheet material, purified water, camera film dispenser, chlorine and a rubber sealant.

Procedure:

• Step 1. Fill the 1.5 liter clear soda bottle with purified water then add 3 tablespoons of liquid bleach and tightly seal the cap. Do not use tap water because this will allow the growth of moss.
• Step 2. Make a hole in the 1’x1’ roof sheet material, just the same size of the bottle’s circumference and insert the bottom part of the bottle leaving it exposed under the sunlight.
• Step 3. Make another hole on the roof of the house (same as the bottle’s circumference) where you want to put the solar bulb and firmly fix the device.
• Step 4. Seal the roof with a sealant to prevent raindrops from getting inside the house. It will produce a light when the water inside the bottle bulb refracts and scatters the light inside the house.The Solar Bottle Bulb is expected to last up to two years before it needs changing.

The key here is that the Soda Bottle should have access to direct sun light. This can be a great Solar Lamp for small villages and houses build in close spaces.
