That's pretty interesting and dang good idea!

I would need pop bottles at least 4ft long :D although regular 2L would light up the attic well I'm sure.

That is pretty cool! I'm like Zap, I would need these to be about 4 foot long but they would be cool.
Thanks!

I like it! so simple but effective. The demo at the end shows just how effective they are.

I have quite a few out houses and sheds with tin roofs and I have been meaning to run power to them for lights but never got around to it !

Getting a good seal could be tricky but doable with plenty of silicone.

Thanks for posting I will definitely be giving it a try!

They do look like they're pretty gooped into the roof tops. At 1:29 you can see how much goop they have.
The coolest part to me is the automatic built in dusk/dawn control  ;)

Yeah... the dusk/dawn control :D

I'd be worried about them freezing up then shifting etc.
I'd like to try it just to see if they really do give out that much light... wouldn't be the first time someone's pulled a hoax on the internet!

I need to replace the tin on most of my sheds so I will most likely just buy a few clear sheets and be done with it.
I can see this working on the hen house, some extra light helps to keep them laying in the winter months.

Nice idea

like the idea of using them in a chicken house, be a usefull idea in the garden shed too, definatly a novelty idea, a good example of nessesity being the mother of invention,ways around the freezing,and the sealing probs,

Taking it a stage further, i suppose it wouldnt be that hard to go bigger in many ways, as long as a substancial   amount is poking in the light, even horizontil ones ie long tube with light inlet on both ends, also i expect algea groth will occur, again probly preventable with additaves,

He says that he adds 2 capfulls of bleach to the water, that should stop algae. I use bleach when I wash our polytunnel cover and it keeps it clear.
You could also use the large water cooler bottles,one concern would be if they where to fall it would hurt!

That water will be loaded with algae in days which will impede light transfer substantially.

Just IMHO

Or Not?

But imagine the nice green hue.  What ambiance!

You guys miss the part about adding two caps full of bleach to the mix?

No algae there. :)

Steve

EDIT -

Someone mentioned freezing too... Instead of water, use something such as isopropyl alcohol. Just leave enough room in the bottle so that it can expand on hot summer days.

That would solve the algae AND freezing problem (unless maybe you're installing them in Antarctica LOL)

The size of the project matters not.

make a parabolic mirror to put around them and have moon lit rooms LOL
 I wouldn't want any filled with isopropal though  I would think that would be like having a series of bombs mounted in the roof . neat Idea though for energy conservation much easier than mirrors and ducting where you have direct access roof to ceiling

Would need antifreeze here, but a good idea for cheap lighting.

Or (if you've got the money) you could use deck prisms like they use on boats - i.e. a lump of glass.

Salt water will prevent a freeze in most climates.

This is Brazil, tropical weather, so no freezing problems. He didn't fill the bottle all the way anyway. If there was freezing there is plenty of air space for expansion. That would also be a pretty hard freeze, if it occurred. The water is under the roof, that's all the water he adds. For the inside at the roof level to freeze would require a layer of snow or an unoccupied building.

It's now being used in the Phillipines.
