Great idea!

Nice. If you use a 2 litre bottle does it equal a 100W bulb?
This could be useful even in the west. I\'m sure there are plenty of back yard tool sheds, fishing shacks and the like that could benefit from some extra light.

THAT IS REALLY GOOD.
I'd make ONE upgrade - USE GLASS BOTTLES - they last an eternity, the plastic ones die in the strong UV.

A nice, cheap lighting solution. It could deliver even more light to lower areas of the room if lengths of 3 to 5 inch wide by X-inch long reflective metal (or any thin, long material covered with aluminum foil) were positioned on the ceiling forming a triangle, square or other geometric around the bottle at any desired diameter and down-facing angle to reflect more of the upper light (which really serves no purpose other than lighting the upper walls) down to where it is more useful.

I have seen log cabins with whiskey bottles fitted in between logs to provide indoor light. No water though, in Colorado it would freeze in winter.

Nice initiative . . . but IS IT ORIGINAL ? On July 2008, O Globo (one of Brazil\'s main journals) reported from Uberaba, Minais Gerais: \"Litros de Luz\" (liters of light) . . .

@Slowburn - doesn\'t whiskey have a lower freezing point? or maybe the light transmission is poor...
This is a lo-tech version of the Solatube lighting system and ideal for underdeveloped countries. One might ask why they don\'t have windows, or would that be spoiling the game?

This is brilliant. There used to be something on sailing ships that did a similar job - a deck prism made of glass, it had a flat area that was level with the ship\'s deck, and the prism shape shone the light through down into the holds etc.
