I had never heard of a Solar Bottle Bulb until I saw this video today.
I assume the bleach helps keep the water clear by preventing the growth of bacteria/germs etc. I don't know how much application this would have with most of our survival plans; I doubt many of us intend to live in such crampped conditions but I just thought I'd pass it along. Every bit of knowledge helps. My apologies if this has been posted before. /edit: +us |
Good info, thanks for sharing!

My inlaws had one of these units in their bathroom. Very nice, but I think the real appeal of the soda bottle is cost. It also looked pretty darn bright! |

Very neat! Per this other video its a pop bottle solar bulb that regenerates 55 watts.

brilliant. Great for warm climates? I wonder how it would do with some antifreeze mixed in? What concentration? Enough to keep it from freezing. Measure the Specific Gravity and consult the Anti-freeze container. I think some of the little baster-type anti-freeze testers are calibrated in temperature already. |

While you guys are all on it, I've been using the same type little trick while camping.
Any flashlight + bottle of water or empty mil carton = lantern The milk carton works best I think, no water necessary and its decently bright for a good sized area. Try it in your basement. |

I use a white plastic bag, easier to pack. Just puff it up with air, wrap around flashlight, and rubber band it air tight. Weighs nothing, packs to nothing, great diffuser. |
LOL. My wifes Filipino and she has some family that just came over to the states a little while back. They saw that video and thought that it was supposed to work at night. Like a home made glow in the dark light. I went over to their house and they had like 15 2 litter bottles charging in the sunlight outside. It was hard to keep a straight face.  |
| Fill some plastic soda bottles with dirty water, leave them in direct sunlight for a couple of days and you will be able to drink water free of most nasty bugs. The UV light kills the bacteria and viruses. The sediment will sink to the bottom of the bottle also. |

The UV light kills the bacteria and viruses. The sediment will sink to the bottom of the bottle also. SODIS doesn't work very well with turbid (dirty) water. It also requires a specific type of plastic to be used (PET) because many materials, including many plastics, strongly absorb UV light. |

Many people dont realize their polycarbonate sunglass and eyeglass lenses (even non tinted), you know the cheap ones, naturally absorb the majority of UV light. |

It only works like that if they drop a AA battery inside before filling with water. TRG |

So, if I ship over a container of clear corrugated panels, I could own that town. TRG That's what I was thinking the whole time. Since they're cutting a hole in the panel anyway why not just glue a chunk of translucent fiberglass over it and forget the bottle? The fiberglass stuff diffuses light very well on its own. |

You're missing the point. The bottle acts as a lens that concentrates light by refracting and reflecting light incident from multiple angles. A simple transparent window of the same size would not be as effective. A full panel might be more effective at peak, but would be less effective at times when the light was coming it at a low angle because most of that light would be reflected. You can observe this effect by holding a panel of glass or plexiglass over your head and turning it from perpendicular to your line of sight to almost parallel while looking through it at an overhead light. When the panel is perpendicular to the overhead light most of it is transmitted through the panel. When the panel is nearly parallel to your line of sight it is reflecting much of the light incident on it. (There is also some effect from the light that is transmitted being more strongly attenuated due to the longer path length through the material in question.) |

So... you are taking the position that a 3'x12' sheet of corrugated translucent roof panel transmits less light than 3" of exposed pop-bottle? I'm gonna sit back and watch the math on this one. TRG |

TRG The bottle collects ambient light and redistributes it. As to your point, If they could afford translucent roof panels, they would be living elsewhere. Come up with another solution that costs <$1. |

TRG No, I'm not. Please read the bolded text. Your 3x12 sheet would definitely transmit more light when the sun is high in the sky. When the sun is low on the horizon, the bottle bulb may transmit more light. |

Try it. Never mind a 5" diameter round piece. No comparison at all. |

aren't most plastics made to break up after exposure to sunlight?
