It's too bad no one here seems to have a clue about portuguese language (and there's nothing wrong with that).

This happens in Brazil, and one of the FIRST things they say in that piece of news video is that it IS about scattering light and that ONLY works when the sun is up and shining... for sealed or no-windowed rooms, saving eletrical power in daylight by NOT turning on regular light bulbs when necessary.

No one in the video is claiming magic or out-of-this-world results.

And the adding bleach stuff, is just to make water as transparent as it can be, and also to prevent a very dangerous mosquito (aegis Egipt, or something like this) to reproduce.

Peace
