SHTF 50 watt lightbulbs from 2 liters

[tyler34]

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

YouTube - Use a 2-Liter Bottle as a 50 Watt Light...

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.

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.

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?

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.
