what do you guys think?
er, it's a light-pipe, right?
diverts daylight down into dark rooms with few or no windows - sort of instant solar energy?
makes better use of the sun's energy before turning-on another I^2*R lamp
i liked the quote "At night, switch off automatically" - yep, i noticed that about daylight too ;)
so, maybe not what some forum members would immediately think of as Free Energy, but still a cool idea

Hi
I think this is a total reflection based solar lamp. Something like a giant optical fiber.
Cool.!
Victor
actually i think the guy says it automatically shuts off at midnight, so i am guessing it stays illuminated for quite sometime after the sun is out?
so is it really chlorox or maybe bleach or something else in the mix?
hi Free
my quote "At night, switch off automatically" is cut-and-pasted directly from their website
the 'switch' happens at sunset! (and the additional light will be pretty weak even before then)
if it was possible to switch it off some other way, they wouldn't need for the old lady to stand on a chair and cover it with a bucket when they wanted to show how dark the room would be without it shining into the room
if there's any bleach product added to the water then it's to stop the water growing mold with time
believe me, like i said above - it's just a clever light-pipe!

actually i was quoting it from the video not the website.
Excellent adaptation of TIR. (total internal reflection/refraction) Yes, I agree this is a light pipe variation. Does anyone know what he used in the end of the bottles? A lens of some kind? Or, possible just a piece of clear plastic (fiber optic)?
This is a great use of this idea. It really seems to put out the light. I don't like all of the holes in the roof with sealant around them, which may leak after a while. It would seem to me that one could have a "collector" and used fiber optic lines that could run to each bottle. This way, only one entry point for the group of lines and they could distribute from that entry point.
Thanks for posting the video.

hi Bill
Moser says he uses a case ('potinho') for a camera film to cover & protect the bottle cap (presumably so the seal doesn't degrade in the UV from the sunlight)
i'm with you on the practical aspects, Bill - holes in the roof don't seem like a good idea to me - i guess it's a trade-off between efficiency and cost: part of the thinking behind this project was 'recycling' everyday objects which they say would only end up as landfill or street debris otherwise
there's another project they have, using similar components, where they just lay bottles refilled with water in the sun & have the UV rays sterilise the water
@Free
it's clear from the video, when you see them visiting buildings to film the 'sun-lamps' in action, that the sun is shining outdoors & then the rooms they go into have little natural light - hence the benefit of adding these bottles in the roof
if these lamps worked after dark they could have visited the homes at night and got a more impressive demonstration
in the video they hold a bottle up to the sunlight straight after filling, so you can see something of the TIR effect, even outdoors
i think you'll find they don't work after sundown ;)
like Bill says, thanks for posting the video - it's a neat idea

I liked this because it's low cost solar lighting.I guess one could use clear plastic tubing for special effects.triffid
I think that is cool 8). Good way of bringing sunlight into a dark warehouse, without unnecessary use of electricity during the day.
LOL
Why not simply make large windows ??
On the roof or in walls and seal them tight.
Did I mis the point? :o
i guess so ;)
this is a village/town near Sao Paulo, Brazil - i wonder what proportion of these good people's wages (if employed) installing even one large, well-sealed window would cost?
they've made good use of water & no-longer-required plastic bottles to make '40W' globes - there's infinitely more 'Free Energy' in this construction than i've seen on most threads in our forum! :)

Although that would look good, I'm not sure that a window would concentrate the light as good as a chamber that is filled with liquid.
What is the bottles ? Any replications ? I would like to try it out ?
How much of the light spectrum goes through ? Does UV Light goes through ?
