Genius! Simple, effective, innovative. These types of ideas are more sexy to me than any anorexic model alive. This is ideal for any business that operates during hours of sunlight.

S & F

I definitely have to try that out.

Time to start saving my two liter bottles.

Yeah I'd like to see a set of plans... I have a shed out back where they would work out fine... never work in my house though...wouldn't be much bottle left to stick out after going through 1 inch of roofing materials then another 4 inches of insulation

Isn't it always the simplest things that make you say WOW! Free lighting and keeps the plastic out of the landfills.

I was hoping to see something more technical than a simple skylight but cost-wise, this proposal is streets ahead of commercial equivalents. It's still dark after sunset though.

Well, paint the room with glow-in-the-dark paint, that will give you some light for a while after sunset.

Plastic 2ltre bottle, Add 2 capfulls Bleach, Fill rest with water. Add plastic film canister to neck, this is to stop the bottles cap from degrading by sunlight.Cut a great big hole through your roof and plug it with the bottle.

there is no trick to this, sunlight will come through the hole in roof wether the bottle is there or not, the only difference is that the bottle defuses that light beam coming through the hole in roof to a more spread out light such as a normal light bulb does. Guess it plugs up the leaks as well when it rains.

You all know this only works in the daylight right?...full daylight...

There is no way this would work with the light of the moon, and during stormy days you will be in the dark, and who uses lightbulbs during the day?

I saw this before a while back.

It's pretty neat and good for a tin roof or thin cement roofs.
But in a typical European house with two floors and an attic it would only benefit the loft areas.

Still good to know though

Simple. Genius

Obviously you would have to use a light bulb at night, but as was shown, one guy was using them in his workshop, a woman was using her in her bathroom. Obviously in an area where glass is expensive and/or hard to come by, its simple things like this that make a big difference. I remember watching a video of an African surgery where they were complaining about the solar panels they had which could only power only 1 or 2 items, and they needed light obviously, so they had to be very careful operating the vaccine fridge. This simple discovery could work wonders for them.

Well a light bulb that works only during sunlight hours and makes your roof leaky, I'm not sure he'd get the backing in dragons den.

What happens when it freezes outside?

Uh Oh

I don't think they have that problem in Brazil.

It is suited more towards warmer climates - like mine.

Fantastic idea.
