You obviously didn’t read the article. These people can’t afford electricity much less window glass. These put out as much light as a 40+ watt bulb. There is no need to be so negative. Check out this link for good videos on these.

I read it. I just think some of the posters here are going goofy over this like they did over Christie and a bunch of other non-events.

Wrong. They don't put out any light. They simply allow light to pass through - same as a hole

These people can’t afford electricity much less window glass.

But apparently they can afford soda.

Try realistic. Use your ability to reason and examine these in the "light" of reason. They're holes in the roof with a bottle in them. They cannot let in any more light than the hole (first law) and they have to let in LESS light than a simple hole (second law). The only advantage the confer is that they keep out the rain and the diffuse the light. A bigger hole with a piece of glass (which you claim they can't aford) would let in more light. A bigger hole with a flap to cover it in the rain would let in more light.
