Introducing Water Lamp

The video below shows a few Brazilians speaking Portuguese, so you English-speaking people reading this post may not understand the dialog. The video is still wortwatching, though. I plan on adding some subtitles eventually, but because I don't know when I'll get to that I thought I'd go ahead and post the video nonetheless.



The video starts with the reporter saying "every bottle filled with water helps save energy". The guy in the blue shirt came up with this idea of filling soda bottles and then placing them on the ceiling. This is a very poor neighborhood, so the reporter says the idea spread very quickly. Then you can see the lady showing her house. The reporter asks her if there's any disadvantage to have this "lamp". She thinks for a few seconds, then responds "there's no disadvantage". She says it works also when it rains, and that they don't have water leaking inside. At 2 minutes and 12 seconds of the video you can see the reporter inside another house. This time they are comparing how the much light they were getting with regular light bulbs before installing these "water lamps". That's why they have dark buckets covering two "water lamps". Then they turn off the light bulbs and it gets dark. Then they remove the buckets from the water lamps. Tye final comment is that they get more light from the "water lamps". The guy in the previous scene says "the light is always on" in that little factory they show.
