Eat Your Vegetables (#2) with Isang Litrong Liwanag

When I was a kid I didn't like to eat my vegetables. At the time I didn't see a need for them. I used to joke to my mom that I would catch up on eating all my vegetables at our next Thanksgiving dinner which of course was months away. I understand now that my mom wanted me to be healthy and vegetables are good for me. This segment is about eating your vegetables, well mentally. The vegetables that I'll be dishing out to you are for your own good. It's a dose of getting exposed to something that might be new to most of you, even outside of the usual surf culture. It's ok if you don't like it, but like my mom said, "at least give it a try before next Thanksgiving."

A bottled liter of water with a few teaspoons of bleach is proving to be a successful recipe for dwellers in the light-deprived slums of the Philippines. The simple technology is spreading sunlight in places where it has never been. Its not meant to replace a light bulb at night, it's used to save electricity during the day. Installation costs about $1 and a solar daytime running light to be installed which produces 55 Watts to 60 watts for about ten months and will work during the day for about 5 years. Please take a look at these video clips to learn more.

How to Build a Solar Bottle Bulb 2.0 

( Updated English Version)

1) Always scratch the sides of the bottle to create better grip to the sealant. The top part where the bottle meets the metal is the leak point in the build so use industrial strength sealant (epoxy or DOW Corning 791) on the top and bottom if possible.



2) Always put a protective cover over the bottle cap as the suns rays tend to make the original bottle cap brittle and a crack in the bottle cap will allow the water in the bottle to leak during evaporation.



3) Always RIVET the metal sheet holder on to the roof.



4) DON'T USE THIN METAL ROOFING SHEETS. there will be no bite on the plastic bottle and the different expansion rates will cause leaks later on. Go for thicker roof sheet.
