SHTF 50 watt lightbulbs from 2 liters

[tyler34]

this is an absolutely brilliant idea for saving money and even better for a SHTF situation.

Thats pretty cool! Dont think i will ever do it though. Only if i knew about that when i was 10yo with that fort built out back.

sounds good... during daylight hours..........

Sounds like a fun experiment. I have an empty bottle and some Clorox. I'll let you know how it goes.

So I think it is awesome; but wouldn't a sky light do the same thing?

And not practical in a climate where the bottles would freeze because the expansion/contraction problems of the water inside the bottles would cause them to split when they freeze.

And not practical in any building where there is an insulated roof/ceiling.

There are some small skylights that work like this, but are designed to be used in our climate and meet our building codes. Anyone interested should do a google search for "SolaTubes" and "SunPipes" as both of these brands meet out building codes.

If you watch the video, they say that it keeps glowing until midnight. That's what I want to see- how long it glows. They use it in a warm, poor areas so it makes sense as cheap lighting. They don't have to worry about freezing.

I don't think it does glow at all. But do your own experiment. Take a pop bottle, fill it with water, put a little bleach in as directed, seal it and then set it outside in the sunshine for several hours. Carry it inside into a closet and see if it glows.

Last time I checked, the combination of bleach & water is not photo-luminescent.

that but they cost $$$$ that was my point is in a SHTF scenario these would be far easier to to do the light tubes(which I think are way better than regular sky lights)

I think the bleach is to keep any algae type organisms away.

When the SHTF I want to see you drilling holes in your roof and trying to find a way to seal it when it rains.

This is not in my opinion a good thing for a SHTF situation, I'd rather be concentrating or more important things.

 

[HICKMAN]

It's still pretty cool

 

[hotfarmboy1]

Its pretty cool, but wouldnt work in most houses with ceilings and insulation. Would work in our barns, or maybe in my back porch But that's about it for us.

I agree with Melensdad on this, I don't think it is about glowing this is nothing more than reflecting. I do however think it is a cool idea and may find its way into the storage shed I need to build. The only way it may "glow" is if the bleach contains phosphates then they might "glow" after being charged with light but I am skeptical about that even.

agreed, I think the "glowing" was lost in translation for reflection.

Perfect idea for lighting sheds, mini-barns and such during the day.

Might also be an interesting way to light the inside of a debris shelter.

Just another why you shouldn't drink water from another country
(in responce to the glowing water)

 

[haldir]

Yeah, if mixing chlorine with water caused a reaction that would produce that much light, imagine how a pool would light up the neighborhood.

 

[Clay]

I think the chlorine is just to keep the water from growing nasties.

Well, actually, when the next Ice Age happens and the glaciers force us to move south to the equator, this could be helpful... Still a neat little trick that I'm sure most of us hadn't thought of. Good find!

Good call Indy, how in the world are they keeping it in the roof water tight? Any amount of time in the roof and sealant would fail causing a leak! Just what I want a leak and then a two liter filled with water falling on my head. Not a good idea although it may work for them.
