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.
