Bottled light in the Philipines


There's a novel, simple idea spreading in the Philipines - using bottles of water as skylights.

The concept is staggeringly simple - slum dwellings are dark, and need light, even in the daytime.

Though they have electricity, it is the most expensive in the area, so they can't afford to use powered lights.

Instead, they use water.

A two-litre bottle of water, with a little bleach to prevent algal growth, is set into a section of metal sheeting, which in turn is set into the roofs of dwellings, workshops, even chicken-coops.  The water-bottle refracts the light in all directions, instead of letting it shine through in a single beam, and provides as much illumination as a traditional 60W bulb.

OK, so this is old news to some people, but it's new to me.

For more information, have a look at the Litre of Light website, or just have a poke around Google and YouTube.

Its a big help especially to families who can't afford to pay electric bills in the Philippines.
Absolutely Nizerbean. Please, Instructable writers and readers, if you can, watch this. You are a very special group of people, and this is a thought provoking clip.

"Clip"? It's an hour-long documentary!

It's a good watch, though. I saw it on TV.
Well, I've certainly been publically shamed-great comment to wake up to. Documentary is in more than one part, I should have said "episode" instead of "clip" I'm sure readers will now be forewarned.
Hey, I don't think you've been "shamed" at all. :)

I like the concept, and the engineer's mind wonders what happens
when it gets gets freezing cold.

I bit of antifreeze (without the coloring of course) might solve that one

Could mix yellow, green or blue. Alcohol is clear.
I think they ship some spirits in plastic containers.
