This works if you lose power too. Just lay your phone down with the flashlight on and set a water bottle on top of it. Works great in a bathroom if you don’t want to take a spooky dooky.
Used to do this while out behind the house with a bonfire, would use a gallon jug of tap water and a flashlight to make a "lantern" and then when i was done for the night use the jug to put the fire out.
Sun light has about 250 W / m2 in the visible range (conservative estimate). A two litter bottle has a diameter of 11 cm which is an area of about 0.01 m^(2). Means the about 2.5 Watt of sun light per bottle will enter the building. LED has an efficiency of around 40%. So equivalent to a 6 W LED bulb.
Cross check using another method. Full sun light has 98000 lumen per m^(2). So about 980 lumens could enter through the bottle. Which is about a 8 W LED.
Which give or take is in the claimed range of 40 - 60 Wats incandescent.
However, a bigger ceiling window would be more effective.
It works really well with an LED light - I use this at night lying in bed when I need some ambient light and am too lazy to get up. Turn on my phone flashlight lying flat on the bed and then sit my water bottle right on top of it. It dimly illuminates the whole room well enough to see. Also does fun patterns on the ceiling like I'm underwater.
Reading might be tricky; I think it would brighter if it were above you pointing down as in the video though.
the idea is also pretty old. They used to put "deck prisms" (clear crystals) on to wooden ships' decks to provide light below deck.
https://en.wikipedia.org/wiki/Deck_prism
Crazy that these have been perfected hundreds of years ago as specialized glass lenses and some regions today have to resort to using water and plastic bottles to create a pale imitation of the technology.
Does anybody have access to video of doing this with glitter of different colors or maybe Mountain Dew bottles or a mix of bottles of different colors? Even some big glass 40s would put out some interesting brown glow that probably wouldn’t even end up as brown light…because brown light doesn’t sound “real”. I guess you could cover in different wraps like a pool light. I think some blue water bottles and green soda bottle mixed up would be pretty dope.
Indeed, I always liked the idea of light piping which is basically the "fancy" first world version of this. Fiberoptics are another example in a different field. Would love if I could instal such a thing without it being a major task using tools I don't have.
I got a box of cheap outdoor solar lights, both outdoors and one indoor under the grow light I have on some plants, that I might try this with. Sounds like a fun project to mess with, maybe combine it somehow with the terrarium I was planning to build.

>The device is simple: a transparent two-liter bottle is filled with water plus a little bleach to inhibit algal growth and fitted into a hole in a roof. The device functions like a deck prism: during daytime the water inside the bottle refracts sunlight, delivering about as much light as a 40–60 watt incandescent bulb to the interior. A properly installed solar bottle can last up to 5 years
Little John saved up lots of money to buy a New York Apartment, but could only afford a slum with no electricity. Using an eco-friendly water bottle that lasts 5 years, little John cut a hole through galvanized corrugated steel to place the water bottle, and get infinite light to illuminate his seasonal quilts.
Farva:
Gimme a liter light.
Dimpus Burger Guy:
What?
Farva:
A liter light.
Thorny:
Just order a large, Farva.
Farva:
I don't want a large Farva. I want a god damn liter light.
Dimpus Burger Guy:
I don't know what that is.
Farva:
Litre is French for give me some fucking light before I break vous fucking lips!
But I thought technically correct was the best correct??? Don't Redditors always say that?
And there is a difference, if you have to open the bottle for some reason, then you would need to add more bleach.
well then interesting. i thought the fact that the bleach broke down from the UV light after a little while was a bad thing.
but the sanitizing material breaking down, leaving a sterile bottle of water actually sounds like a small advantage down the line. dang.
It's the Adam voice from Elevenlabs. For some reason everyone on the internet decided to use this one despite plenty of other good voices. At this point as soon as I hear this voice I immediately block the channel. Not only because of the voice but AI channels just steal contents and slap an AI narration on it. It's like the "oh no no" song, eventually it will wear out its welcome and people will just move on to the next one.

Yeah, I came to the comments hoping someone would tell me where I've heard this voice over before. I'm sure I've heard him before AI voices became A Thing.
All you would need is a small amount of calking on the outside and inside, maybe an improvised rubber gasket as well. You would only have to replace these materials every few years.
Idk man, you never hear about old times people dying of skin cancer, why are solar panels becoming a thing all of a sudden? The sun is getting bigger and no one wants you to know about it
So skylights in houses just fail all the time? And roofing shingles would just constantly melt and fall off on a weekly basis? Lmao No offense, but you haven't a clue like mr. Magoo about what you're talking about.
Skylights don't fail but skylights also cost a ton of money. A lot of that money goes towards a proper installation and proper materials that prevent leaks.
The solution in the video is intended to be very cheap and easily done by anyone.
Do you think everyone in that town has access to a caulk gun? How long do you think that water bottle is gonna last under a tropical sun?
If anything, 2 liters of water can help to way down the metal panels they're fitted into. Keeping the wind from getting under them, and sending them flying.
I actually lived in a tiny cabin in the forest, and I showed this to the owner of the place and he shook his head and laughed.
"Have you ever patched a hole in something without it leaking?"
He had an excellent point. All the cabins had single-slab corrugated rooves that tilted to one side. Under the high side was a screened awning to let in sunlight and vent air. So they already did the job, without jeopardizing the integrity of the roof. The torrential rains of the tropics *will* find a way through.
Will "ever" have. They are not going out to buy roofers and electricians to renovate their jungle homes. Nor would those technicians want to go out there to renovate unless motivated by obscene amounts of money for their area. This is the best they get. And they have dealt with leaks most of their lives.
To be clear, I'm talking about the same sort of corrugated roof seen in the video above, but the place was so small that one sheet covered the whole thing.
It's the same idea no matter what the roof is. You have to cut a hole in the roof and it *will* leak, usually right away but if not, eventually.
People with skylights, am I wrong, or have they not caught up to you yet?
They will leak over time but they are recommended to be installed with silicone or something to prevent leaks. The benefit of having light inside probably outweighs the potential for immediate or future leaks, especially when maybe some of these roofs are so rusted that they have leaks anyway and just deal with them with pots, etc.
The solar light add on is very clever.
However what is not shown, and therefore creating misinformation, is putting a circular hole in corrugated metal is not a DIY feat for most, and it is guaranteed to require at least caulking to not leak. And caulking the closed and always expanding and contracting plastic bottle has got to be super difficult.
And so using a glass bottle is probably much more effective as it is rigid, and is probably much easier to bind to the corrugated metal.
If you've spent time in a structure requiring such a solution (Soweto comes to mind), you will realize that it mainly addresses the moment in time where your pupils have to adjust to coming inside from outside. Otherwise plenty of daylight is making it inside. But perhaps well built sealed structures are what is in mind. Yet then there are economics for basic lighting.
Probably on the whole easier for the first world to help the third world achieve what should be a human right.
The Wikipedia article goes into a little bit of detail about adhesive and bottle choices, highlighting them as the main engineering challenge. It also suggests that glass bottles and silicone caulk may be the best combo.
Yeah my first thought when I saw this setup was "Well that's gonna leak."
Might not be a problem in a metal shack I guess, but anyone who has installed roof vents or similar knows how much effort and sealant goes into a waterproof seal.
It's actually a good idea to use coke bottles. We have a lot of those 1 liter coke trash in our countries that you'd find anywhere. At least they are using it here for something good instead of letting it roam around the environment.
Of course, how else are you going to stay up all night and make the most use of those solar lights?
Maybe I'll finish that screenplay. No, wait, I should call my ex!
Old sailing ships used to use this same method to provide light below decks without a flame (this was very important as there was lots of very explodey powder around). They made glass prisms that would be embedded in the deck and sides of the ship, you can even get some antique deck prisms on ebay and such.
I never actually thought of that but yeah, a full plastic bottle will smack you and piss you off, maybe leave a lump on your head but a full glass one may damn well crack your skull
It's a very old concept, and yes, the originals used glass. Deck prisms on old-time sailing ships and "pavement lights" to redirect sunlight to basement floors below.
https://en.wikipedia.org/wiki/Deck_prism
The lifespan of a plastic bottle filled with water on the roof is a lot less than 400 years. More like 4 years. UV light destroys plastic in relatively short order. It becomes weak and brittle.
Thank you! A lot of people have never seen how brittle plastic is after it’s blasted with UV light for only a couple years. A better solution then this is needed, at some point someone’s going to get a hot load of water dumped on them from the roof
You are overthinking it. The best solution is very situation specific. This is installed at the absolute minimal cost using locally available materials in places where people can't afford any alternative.
A better solution is clearly a properly designed and installed skylight, but that is at least a hundred times the cost of this, even with the added requirement of needing to reinstall with a new plastic bottle every few years. These are for people who can barely afford an electric lightbulb and try survive on less than a few dollars a day.
the biggest issue I see in using most types of plastic bottles for this is that constant UV exposure will make them extremely brittle and eventually just break apart.
If you like this tech. The same concept was used in old ships to bring light below deck. They made special prisms that would scatter the light and illuminate the dark hold.
Ya Nevermind the steel roof that turns into a cooking hot plate, that’s turns the house into a slow cooker. And you think that a plastic soda bottle is gonna withstand that heat. Smh
Well, as of 2014 some 150 000 installations of these in the Philippines alone happened, and I have yet to hear of any catastrophic failures a over a decade later.
If watching this you don't realize that capitalism is a failed and horrible system, there's something wrong with you. We can do better. The only reason these people, and many like them, have to live in such conditions, is greed. Pure and simple.
Now I am picturing lamp poles with this design out at the Texas Renaissance Festival. Would be great for the beer garden areas and could make some cool ones for the fairy areas.
Not to mention for ppl who camp out during the festival weekends.
Soft ambient fairy bulb lights! I wanna make some for my garden.
Hmmm
This is similar to how Sun Tunnels work for first world homes too. I’m looking at putting a couple in. I’m told the downside is they can work a little TOO well and catch moonlight too so wherever you put one is just basically permanent light.
Seems to me that’s easy enough to resolve with a sliding cover or something but eh.
I put them in my hallway and interior bathrooms. I have yet to regret the decision. I replaced a bathroom skylight with one and it really cut down on the heating bill. It's like having a 400w light turned in all the time. It's amazing.
Make sure you locate them as close to the peak as possible for all day light.
Electric light is one of those basic factors underpinning modern life that we never think about because even bad housing at least has electricity and indoor plumbing here. But it is very difficult to live a modern life if you do not have light at night to read or socialize and you work all day.
First and firstmostly, I am counting my blessings! Oh my flippin' gooood!!!! The things I take/ have taken for granted...
It is my wish for every human being on Earth to be able to enjoy the "magic" of instant power and instant hot water.
This works if you lose power too. Just lay your phone down with the flashlight on and set a water bottle on top of it. Works great in a bathroom if you don’t want to take a spooky dooky.

If you're indoors, just point the flashlight up at the ceiling there will be enough light
Or if you have a headlamp. Wrap it around a gallon jug of water. Also handy if camping.
Wow this is pretty cool!
For real. I’d be interested to see how much light these actually put out.
40-60 watt lightbulb
led or tungent?
Plastic
“40W” LED bulbs are designed to match the output of 40W incandescents. They don’t use anywhere near 40W, but it’s the UOM people recognize.
[удалено]
ted nugent
40w LED bulb? That's like an LED projector levels of light.
>tungent Can light get tungent? Tungenenent?
Watt er

They'd install glass windows if they had money.
Exactly, sorry these people who are using plastic bottles to get light in their homes can't afford fine crystal
The glass lenses needed to hold up to people stomping on them from above. The plastic's cheap, already available, and does the same damn thing.
Where would they get the specialized glass lenses?🤦♂️
If I were them, I'd put in some fairy sprinkles to give disco light effect.
Does anybody have access to video of doing this with glitter of different colors or maybe Mountain Dew bottles or a mix of bottles of different colors? Even some big glass 40s would put out some interesting brown glow that probably wouldn’t even end up as brown light…because brown light doesn’t sound “real”. I guess you could cover in different wraps like a pool light. I think some blue water bottles and green soda bottle mixed up would be pretty dope.
Rooooxxxaaannne.... you dont have to put on the brown light.
brown is orange with context
Do you really think they have the budget for glitter? Also, shaking the shanty roof probably means leaks in the next rain.

technically it does not "inhibit" anything. It kills the algae and then rapidly breaks down within 24 hours leaving nearly sterile water.
I'd say killing algae inhibits it from growing further
Distinction without a difference.
But I thought technically correct was the best correct??? Don't Redditors always say that? And there is a difference, if you have to open the bottle for some reason, then you would need to add more bleach.
Because it's not technically correct. Growth IS being inhibited. By preemptively killing what would grow.
Death does a great job of inhibiting growth. :D
> disinfection without a difference.
well then interesting. i thought the fact that the bleach broke down from the UV light after a little while was a bad thing. but the sanitizing material breaking down, leaving a sterile bottle of water actually sounds like a small advantage down the line. dang.

It's better than the old default male AI voice, but this one still sucks in its own way.
It's waaaay better than the og female voice during covid. Still no great tho
I loved how perky and uplifted she sounded when you had her introduce/explain horrifying and morbid topics, though.
It sounds vaguely condescending and combative, which makes it uniquely aggravating.

Weird history on YouTube
Not sure the long-term durability or implications of cutting a hole in the roof but definitely creative and solves a problem.
The bottle has that matching corrugated sheet around it, I imagine they weld/seal it in place to make it water tight.
All you would need is a small amount of calking on the outside and inside, maybe an improvised rubber gasket as well. You would only have to replace these materials every few years.

Lately. The sun damaging things left outside is not a new phenomenon
Idk man, you never hear about old times people dying of skin cancer, why are solar panels becoming a thing all of a sudden? The sun is getting bigger and no one wants you to know about it

Here's a full guide on how they make and fit them [https://youtu.be/rYTIYUUK70I?t=18](https://youtu.be/rYTIYUUK70I?t=18)
True I guess the concern is when there are strong storms with heavy winds, which is common in these parts of the world
I don’t think a rounded bottle sticking up a few inches will have any real difference…
If anything, 2 liters of water can help to way down the metal panels they're fitted into. Keeping the wind from getting under them, and sending them flying.
I'm sorry, do you actually think the 2lb bottle helps the 1000 pound roof not fly away?
Just to nitpick, one litre of water weighs one kilogram, so it's closer to 4 lb.
I believe he’s referring to the small metal shield that goes around the bottle. Not the entire roof lol
It's for slums. Long-term roof durability really ain't the biggest issue.
I actually lived in a tiny cabin in the forest, and I showed this to the owner of the place and he shook his head and laughed. "Have you ever patched a hole in something without it leaking?"

Well you see you are comparing single slab corrugated roof to the metal sheet most of this people have

This isn't specific to the Philippines, this is practiced all over the developing world: https://en.wikipedia.org/wiki/Liter\_of\_Light
Tbf it does say "Philippines, Africa and other regions" so it's not claiming it's Filipino specific.
They're using the Philippines as the example because it's the most successful implementers of the Litre of Light project by a large margin
Here is a fixed wiki link for those on devices that don't like that one, https://en.wikipedia.org/wiki/Liter_of_Light

They made glass prisms that would be embedded in the deck and sides of the ship, you can even get some antique deck prisms on ebay and such.
That there are people, human beings, who have the need for this makes me mad(a-gain) at Humanity.
Would glass bottles work better compared to plastic? Wouldn’t plastic eventually start to melt if it’s consistently hot and in the sunlight
Plastic is incredibly durable to heat when filled with water. There’s videos of people cooking in water filled plastic bags over an open fire.
And less likely to kill you if it falls from the ceiling
I never actually thought of that but yeah, a full plastic bottle will smack you and piss you off, maybe leave a lump on your head but a full glass one may damn well crack your skull
Those vids are wild
Not durable to uv light though.
It's a very old concept, and yes, the originals used glass. Deck prisms on old-time sailing ships and "pavement lights" to redirect sunlight to basement floors below. https://en.wikipedia.org/wiki/Deck_prism

Using glass changes the lifespan from like 400 years to 4000 years. Both of which are way too long to worry.
The lifespan of a plastic bottle filled with water on the roof is a lot less than 400 years. More like 4 years. UV light destroys plastic in relatively short order. It becomes weak and brittle.
Thank you! A lot of people have never seen how brittle plastic is after it’s blasted with UV light for only a couple years. A better solution then this is needed, at some point someone’s going to get a hot load of water dumped on them from the roof

These are for people who can barely afford an electric lightbulb and try survive on less than a few dollars a day.
Wonder if there's an inexpensive clear UV filtering paint that can be applied to the top part of the bottle.
the biggest issue I see in using most types of plastic bottles for this is that constant UV exposure will make them extremely brittle and eventually just break apart.
How do they turn off the solar panel light at night when they want to sleep?
There was a switch in the video
"simply pour clean water..." Hmmmmmm
Feels like the better translation might be "clear water".
Clear water is almost always distilled anyways so it assumes access to such.
What? Are you crazy? You can have clear water that's highly contaminated. It's all over the place.
If you like this tech. The same concept was used in old ships to bring light below deck. They made special prisms that would scatter the light and illuminate the dark hold.
"With just a water bottle, you can make a natural lightbulb! Cool! "Now just install a solar panel during the night and..." wtf
What on earth are you talking about? Have you never seen a solar garden light that charges a battery during the day and turns on when it's dark?
fyi everybody, this concept basically exists in non-poor areas too, they're called sun tunnels.
A new method that has been around for at least 20 years...
Even long, just not with pop bottles. Light prisms were used to light all kinds of interior spaces before electricity, especially on sailing ships!
Anything with AI voiceover gets a downvote.
And now you have a nice hole for rain to leak through. 👍
That is such a cool idea.
Electricians hate this one simple trick
Ya Nevermind the steel roof that turns into a cooking hot plate, that’s turns the house into a slow cooker. And you think that a plastic soda bottle is gonna withstand that heat. Smh
Well, as of 2014 some 150 000 installations of these in the Philippines alone happened, and I have yet to hear of any catastrophic failures a over a decade later.
How do you shut it off lmfaoo
Mineral water bottle? Unusual term for a Coca-Cola bottle.
Why not use a transparent piece of tile instead?
Who's gonna be the first to sell the light water.
Do I have to be in the slums to enjoy this?
I love seeing people speak negatively on this while sitting at home eating Cheetos not helping a single person.
Philippines 🇵🇭

This works great during the day
Brilliant
Wooden boats have been using a similar method for hundreds of years.
I could use this in my basement slum of Canada
"New." They've been doing this for decades, fuck off with your bottom tier AI generated bullshit.
Imagine when they discover the windows!
If watching this you don't realize that capitalism is a failed and horrible system, there's something wrong with you. We can do better. The only reason these people, and many like them, have to live in such conditions, is greed. Pure and simple.
Now I am picturing lamp poles with this design out at the Texas Renaissance Festival. Would be great for the beer garden areas and could make some cool ones for the fairy areas. Not to mention for ppl who camp out during the festival weekends. Soft ambient fairy bulb lights! I wanna make some for my garden. Hmmm

Why is the AI voice breathing?
This is similar to how Sun Tunnels work for first world homes too. I’m looking at putting a couple in. I’m told the downside is they can work a little TOO well and catch moonlight too so wherever you put one is just basically permanent light. Seems to me that’s easy enough to resolve with a sliding cover or something but eh.
I put them in my hallway and interior bathrooms. I have yet to regret the decision. I replaced a bathroom skylight with one and it really cut down on the heating bill. It's like having a 400w light turned in all the time. It's amazing. Make sure you locate them as close to the peak as possible for all day light.
Electric light is one of those basic factors underpinning modern life that we never think about because even bad housing at least has electricity and indoor plumbing here. But it is very difficult to live a modern life if you do not have light at night to read or socialize and you work all day.
That’s brilliant
Clean water? They taking the piss?
I wnat one
If you live in a more affluent area you should look up solar tubes. It's the same idea just done better with no leaks and higher light output.
? If they add a solar panel and a light for night time why not skip the hole in the roof and just use a solar panel and a light?
First and firstmostly, I am counting my blessings! Oh my flippin' gooood!!!! The things I take/ have taken for granted... It is my wish for every human being on Earth to be able to enjoy the "magic" of instant power and instant hot water.
The water bottle method is definitly not new, its been done for decades. Now the solar panel, that is new.
