I remember reading a story about people in a very poor country using this method to light their windowless shack during daylight hours. I couldn't find it but here is the idea.

Yes, those bottles work reasonably well. I've seen them in operation in a few places. In places where they get monsoons, the bottles aren't real effective because of low, heavy cloud cover, and they're prone to leaks around them. I usually try to bring small solar powered lights, because either there's no electricity, or the electricity is intermittent.

did i ever mention i have a fondness for old sailing ships? they often used a deck prism to pipe light below decks. same idea new materials. The coke bottle idea is cool but won't it turn green in a week or two?

That's why they put a little bleach in the water in the bottle. The bleach keeps the algae from growing.

cool, that would fix it.
