Even in those poor countries like the Philippines, these dwellings are considered boxes and the people "homeless". I have a sister in law in one... they move out and crash at a relatives place whenever it gets wet because the water flows right through (several feet deep) and everything gets wet. I am glad they can at least have light. This is a family that has a "good" job. |

| For any climate colder then San Francisco this is a very bad idea. Liquid filled bottle will be a huge thermal wick and rob you of far more energy than it supplies. Use these bottles on your shed but not in a heated building. Almost any window idea you can come up with will be better than this one. You'll notice none of the roofs in the videos were insulated. This isn't because insulation is unnecessary, it simply a function of poverty and lack of resources. A roof like that gets hot as hell here in Canada so it must be even worse in tropical heat and humidity. | |

Here is a quality video on this, on its use in the Philippines. http://www.youtube.com/watch?v=SBWi3NtND68&feature=share |

Do you know how old the pop bottle deal is? They have also been around for years. I have seen the same video show up 5 or 6 times... years apart. I suspect the video is older than youtube. It is a light pipe, like a large fibre-optic strand. It works on the same principal as a microwave wave guide.... as does the sun tube. The pop bottle is great in a tin roof in a dry place with lots of sun. |

While what you are saying is true, I would have a very difficult time utilizing soda bottles into my home. There are many ways to do this type of thing. To each their own. |

Let's see...a 2 liter bottle of club soda costs a dollar or so plus deposit - .a few months ago there was an ad running in the local buy & sell for a couple of those sun tubes for $300 each.... just saying ...

Hasn't this been invented. What about sun tubes? They've been on the market for years. They have a very impressive track record and come in several styles. Just saying .... |

A high tech version http://biohome.net/offthegrid-technical-files/bubble-windows/ "One of the keys to saving on electricity is using the sun for lighting. The bubble windows spread and soften direct sunlight (and moonlight) from every angle. They illuminate the interior smoothly with no direct light source, no bulbs to replace, and no electricity. In the summertime, when the bubble windows are filled with water, the “solid” quality of the bubbles allows plenty of light with minimal heat. They are far more efficient at insulating than typical pane windows. The seam is a flange sealed in the structure wall, rather than a rubber or silicon seam that will decay over time. The windows allow a full sunlight spectrum into the green room for growing food bearing plants, scrubbing, and recycling the air. Just the sunlight through one 16" sphere is enough to illuminate the BIOHOME's "Ready Room" - plants love it! The Bubble Windows are a special manufacture designed for BIOHOME. They are lightweight, strong, and long lasting. The round shape gives them a new strength that pane windows don’t have, and the round quality allows amazing amounts of light to flow into your home." |

Just use a light shelf and clerestory windows and you'll get better results. No holes in your roof either. |

Bottles of water are placed partway thru the roof and provide interior lighting. ABOUT THE INVENTOR http://www.youtube.com/watch?v=_zMAWztZ6TI&feature=related FREE LIGHT FOR CHICKEN COOP http://www.youtube.com/watch?v=1umwvQ_hMHQ&NR=1 ANOTHER APPLICATION – BARN LIKE STRUCTURE http://www.youtube.com/watch?v=Ncizu6OV3fk&NR=1 NOTES: "Maybe some antifreeze could be added to the water in cold climates. Alcohol is clear and used to be used as an antifreeze. Alcohol is flammable. Would it be safe to use in a solar light fixture like this?" “Cable installers use fiber optic cable they are left with pieces that are not worth dealing with you can get these cable of various lengths and they will convey light to the interior of rooms that cant get light directly. I promise you if you know someone that installs cable or works for a phone company where you can get this stuff free you can use it for lighting in your home.” “You could add some phospho Luminescence or other glow in the dark chemicals to the water to get it to stay lit when the sun goes down. Great idea!” |
