A liter of light for the poor

[GliderGuider]

This is phenomenal! A liter of water, some bleach and a discarded pop bottle changes lives.

1. that is amazing!

2. Let's send them our gallon milk jugs - that would be even MORE light!

So, in Manilla they might even not know about gallon plastic milk jugs!
The several times I've been to Europe I've never seen a gallon milk jug.
Mostly in Europe they use a square cardboard package for milk (that doesn't need to be refrigerated before being opened).

Also, CNN had a 'CNN Hero' segment in KENYA, Nairobi - a while back regarding solar lights, here's a link:

Thanks for posting that and, as you say, providing something
to smile about today!

4. Those would work for the daytime, but some solar lights

could be used at night for light.

5. Not "but" --- "and"! The solar LEDs are being distrrubted by "Light Up The World"

Light Up The World

Light up the World (LUTW) was the first international development organization dedicated to illuminating the lives of the world's poor by providing affordable, safe, healthy, efficient, and environmentally responsible lighting.

In 1997, Dr. Dave Irvine-Halliday, a Professor of Electrical Engineering at the University of Calgary, had the vision to use LED lighting to bring practical, economical, and environmentally safe lighting to the developing world. While on sabbatical in Nepal, Dave visited local villages and was struck by the poor conditions of the people. Most of them were relying on kerosene lamps which produced little light and filled the homes with dangerous smoke. As the annual income of the Nepalese villagers averaged $200 USD, Dr. Irvine-Halliday realized that there was a great need for simple, safe, healthy, affordable and rugged lighting.

Dave had been working with LEDs for more than two decades, and spent most of 1997 and 1998 trying to make an acceptable white light from various combinations of colored indicator LEDs. He made white light but it was simply not bright enough to be of any practical use in the developing world. Nichia, a Japanese company, had invented a bright White LED a few years earlier and Dave immediately requested samples. The 'eureka' moment occurred when Dave lit his first White Light Emitting Diode.

6. It's a solar tube, made with easily obtained materials.

Good idea. Bleach keeps them from clouding with algae too soon.

Larger jugs might not be so good. Full of water they might put too much weight in a concentrated area of the roof. Better to use several small ones, spread out.
