A rhetorical question perhaps!
-
nope truelly want to know if there is anything in this, found it online
-
If there was anything in it wouldn't people cleaning their toilets and sinks have been reporting the same thing for decades?
-
It states "creating a lightbulb". What exactly is the claim ... if they are using it as a diffuser it could make sense but not to generate light.
-
It's not the water and bleach creating light - it's refracting from the top of the bottle (outside, above the roof) to the bottom (inside). Look at the bottom left photo.
Apparently, the light emitted at the bottom end of the bottle is compatible to a 55W bulb.

Just Googled it, yes you're right. Similar ideas are available commercially sold under the name Sun pipe or similar I think .

I understand that in some 3rd world countries they rely on this for light in dim areas during the day. People specialise in fitting them. Half is outside to gather the light the other half inside to illuminate the room.
I assume the bleach is to keep the water clear.

that makes me think, the last job i worked on with K.H had 2 tubes from roof to landing ceiling, inside tubes were very shiny mirror finish sides the light shone through and lit the top of stairs very well

Ive read a few posts about these light diffusers, thing is i cant remember where, they do work tho
-
Saw that idea a few years ago, it's used in shanty towns.
Can't remember the equivalent wattage but I think it's about 60w.
One major drawback though, you can use'm at night.

yuo could if you put a lightbulb in them.

I have it on good authority that they work. (NOT the BBC)
They were apparently thought up by a Filipino, and are quite common in flipper land. Now and again the BBC or Daily Mail does a major exclusive scoop, and attributes them to an Indian or a Brazilian. My guess is that Captain Caveman probably figured it out, with a large chunk of ice.
Mostly used in tin shacks, where the streets are narrow and don't let the light in.

It was I!!! I posted it on vod donkeys years ago, saw it on hackaday.com. There was a video about it on YouTube or somewhere. If you ever lift a clear glass filled with water in a lit room (sunshine or otherwise) you will see movement of reflected light. The water is refracting the light like a magnifying glass. Bleach is there to stop the growth of algae.
Only practical if you have a very thin roof. Like the corrugated ones in shanty towns!

They would work well in our bio/veg sheds.
I have no windows in mine, so need lights on in the day.
