How to build a Solar Bottle Bulb ???

          Light up dark areas in your home during daytime using this green and sustainable concept. Recycle used clear plastic soda bottles, add water+bleach, then install. After installation this solar light bulb can provide approximately 55 watts of light from the sun! T

 

he communities who benefit from this idea live in areas where the houses hardly have windows and live in darkness even during daytime. Their solution up until this innovation was to turn on the light bulb and use electricity.

You Will Need :

• PET soda bottle
• Galvanized Iron (GI) sheet
• Rubber sealant
• Bleach
• Filtered Water

Process :

Cut approximately 9 x 10 inches of GI sheet (corrugated or flat). 

At the center of the GI sheet, draw 2 circles.

And Cut the internal circle.

Cut the 1 cm difference radially, making strips and bend upwards, perpendicular to the GI sheet.

Using sandpaper, scratch the surface around the upper third portion of the soda bottle where the GI sheet will be placed, to allow the rubber sealant to stick better.

Insert the bottle into the GI sheet until the upper third.

Apply rubber sealant on the strips above and around the area below. Wait to dry.

Fill the soda bottle with filtered water and ~10 mL (2 capfuls) of bleach.

Cover with its original cap.

The solar bottle bulb is now ready for installation !

Installation :

Cut a hole on the roof, similar to the bottle circumference.

Place the solar bottle bulb into the hole. Make sure it is firmly in place.

Drill 4 holes on each side of the solar bottle bulb using Bosch lithium-ion cordless drill and put in the rivets.

Apply rubber sealant around all edges of the GI sheet of the solar bottle bulb to avoid leakage. Make sure to cover the rivets.

Place a protective plastic tube on the bottle cap and apply rubber sealant.
