Make light from a water bottle?

Here is a brilliant idea. Yes, really. By placing a one litre water pop bottle filled with water in the ceiling, it turns out that it is bright enough to brilliantly light up a room. Brilliant!

A clear one-liter pop bottle is filled with water, chlorine is added, after which the bottle is attached to the ceiling, through a hole in a piece of corrugated tin. A hole is also cut in the tin roof of a house, and he tin-and-bottle is secured over the hole so that the bottom of the bottle hangs down through the ceiling. Lastly, caulking is applied to prevent rain from getting in.

Here is the really cool part. When sunlight hits the roof and the top of the bottle, its rays are carried down through the water and dispersed into the interior of the room. This provides about as much light as a 55-watt bulb.

This system produces light during daylight hours, and it also diverts bottles that might otherwise end up in a landfill. Event though the bottles don't provide light once the Sun sets, homeowners do at least have the option of performing indoor activities that require illumination during the day, when the light is available.

The videos below show the installation process, and the effectiveness of the bulbs.
