Interesting idea. I'm sure they stop working sometime around sundown. But it would be much less expensive than setting up solar lamps in a garden shed or such to help out with daytime light issues.
I'll be keeping this in mind and trying it later in the year.

Very ingenius idea, but your roof has to be pretty thin for this to work and it may embolden people to cut holes in the roof who really should not be doing so.
Might work in outside sheds and such but in the USA, where homes have attics and thick insulation, likely not so much for the main living areas. Windows give enough light if there were no electricity. Do you really want to compromise your roof?
Now, for a garden shed or chicken coop it might be worth a try. But, in northern climates, will that bottle freeze in the winter? I've never set bleach out in sub-zero to test.
Sure if you can afford it. But the people in the video can't afford such luxury.
I was only half joking but there is no way I would put holes in the roof and hang a bottle with 4 plus pounds of water in it, you are just asking for a leaky roof.

That's cool, and i agree that it may not be wise to have those lights in main living areas (you might be inviting thieves or something). However, it does benefit those who live in poorer communities. It's a great supplement to that yellow light the lady in the video used.
If your going to cut a big hole in your roof, why bother with the bottle of water. Just cut a hole and let the light in.
