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

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.

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 think that is cool  . Good way of bringing sunlight into a dark warehouse, without unnecessary use of electricity during the day.

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!

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 ?
