    A while back, I posted a topic regarding a device I called Eco Glo. My partner and myself have completed the first prototype. Eco Glo is a phosphorescent lamp that applies the concept that two parallel sheets of high-glo sheeting will charge each other during the release of light. This will result in a slight loss of energy but cause the light to be released in a steadier and more prolonged rate. We have 2 other designs to be build since the concept has been proven by various tests (will elaborate in required). The applications of this device are as follows:

    1. Child's Night Light: (The light given off is a 'comforting' amount and should cause the child to feel secure. In other words, it illuminates the room but does not give off as much light as to disrupt sleep.

    2. Camping: In stead of flashlights or wind-up lights, it could be used to illuminate a large tent and provide enough light for any late-night excursions.

    3. General Power Conservation: If you are attempting to save power or help the environment, this device is perfect as it does not require a change or replacement of any part. Once it is purchased, it will remain usable (unless you smash it).

    4. Power Outages: This device could be used it case of an emergency. If you have charged it previously, it can be used to find required items (such as matches, torches etc.). I would not suggest it as your primary light source in this situation.

    5. Industrial Use: Late night workers at hospitals or factories do not need much light, simply enough to get around. An larger model of this device may be required for this application.

    I don't believe this is another cooky idea like some found on this site. It is a simple concept that works. We will be entering it in the upcoming Science & Engineering Fair.

    P.S. Don't try to copy. We have documented proof that we got to this idea first. Please reply with your thoughts, thank you. :-D

    Edit: I forgot to mention. I am not trying to describe this idea as revolutionary or anything. It is just going to be marketed (If successful) as a Power Conserving Device, nothing more... :-D

    Nice. Sounds like you're truly onto something. Besides the yummy name "Eco Glo" will sell itself. :-D

    When you get to design, I strongly recommend thinking backwards from the manufacturer's POV, and even the packagers. I hate to say it but some crappy compromise in the vein of *cough*Chinese*cough* production could make or break you. I don't know what's wrong with our country that everything we make has to cost triple so we can feel proud of our product built just right... which doesn't sell. I think you know what I mean.

    Can you make Eco Glo to sell in Taiwan?

    I am only 15 now so I can't see this project going any farther than I can throw it. Currently, I am trying to prove to people in my local area that this thing works. I don't see it being anywhere near Taiwan anytime soon unless I can prove to my judges at the Science Fair that it deserves to go to Nationals or Internationals.

    The things I need to prove are:

    -The parallel sides of the device to charge each other during use.
    -It is more effective that a regular sheet of phosphorescent paper due to the design.
    -It can match up to other eco-friendly lights currently on the market.

    Here is the design of the first device:

    This shows the amount of Aluminum used. Some of the amounts may have been tweaked during the building process.


    There are to of these phosphorescent triangular sides. These are facing each other in the device, thus charging each other. This creates a smoother and more prolonged release of light. The mirrors are placed to either reflect light back into the phosphorescent sheet or out of the device.


    There are three mirror components. The hypotenuse is placed at a 45 degree angle so that light coming up from the base or from the front face will be reflected out of the device.

    Please comment with constructive comments please. [/i]

    Can it be made with cardboard instead of aluminum?

    Can it be made to fold up?

    Cardboard is not my first choice as it is supposed to be made for camping and other outdoorsy activities but for the finished product, plastic or wood are my favourite choices. It could be made to fold but that is beyond my ability to build (I am not a big tools guy). Wood is that most likely choice of material as it is eco-friendly and compliments the green light given off from the phosphorescent material nicely. As of yet, metal is the only material I can get my hands on. By the way, that diagram is incorrect, we are currently using thin, stainless steel sheets.

    Nice design. I wouldn't go with metal though - more expensive.

    Agreed, but the metal was donated to me by my school so I don't really have anything else. Next school year, I'll have access to wood .

    What is your plan to prove these things?

    Proving Parallel Sides:

    -Obtain a light meter and charge only one side of the device
    -Place the device in a dark room to eliminate all light variables (such as light entering the device during use and charging the uncharged side.
    -After a currently undetermined amount of time, test to see how much light s coming off the uncharged side.
    -Since there is no other light, the only thing that could have charged it is the light from the other side. If it has not been charged, theory gone. (I have already tested it without the light meter and it seems to work so I think that one is okay)

    More Effective Than Regular Sheet:

    -Get a sheet of the phosphorescent material the exact size of the material in the device (If it weren't in the device)
    -Charge both the flat sheet and the device from the same light source, at the same distance for the same amount of time.
    -Use the light meter and a timer to create a line graph showing amount of light given off compared to time. If my theory is correct, the Eco Glo should have a smoother depletion of light than the regular sheet due to its design.

    Match Up To Eco-Friendly Lights:

    -Pick out a few of the top-selling ecological lights and repeat the above test for all. (e.g. Wind up a wind-up light and test to see how long it lasts and how much light is given off. According to the manufacturers, 1 min of winding = 15 mins of light. Therefore, it should give off a more intense amount of light in a shorter period of time. Therefore, they're equal. It just depends on what you want, length or intensity).

    I suggest you hurry up and do the test, 'cause I don't think it will work. I think the losses are too much. The phosphorescent material only gives back a small portion of the light you charged it with. A tiny percentage of a tiny percentage leaves basically nothing.

    Here is something you could try. Charge it up with a lamp, then put a sheet metal partition right down the middle to prevent one side from charging up the other. Measure the light output after a while. Then try it without the partition and see if that works any better.

    Why do you think it won't work? (Scientifically)

    I can't prove it scientifically, but here's the way I look at it. Let's say you light up a piece of your glow-in-the-dark material with a 100 watt bulb. When you take away the bulb, the phosphorescent material gives off some light. Is it equal to the light of the bulb? No. What percentage would you say it is? Maybe the light of a 5 watt night light?

    I doubt it would be that much, but let's say it is. That's 5 percent of the original source. Now how much will you get back from lighting up your material with the equivalent of a 5 watt bulb. Well, it would be 5 percent of 5 watts, or a quarter of a watt. And I think that's optimistic. So, I don't think your self charging concept will make any noticeable difference.

    Well, we are doing a test on which light source is the most effective. So far, it seems like sunlight. Remember, the longer you charge, the brighter it'll be. It's not just about the intensity of the light source.

    Edit: It stays brighter than a 5 watt bulb for about 30 mins, then is about as bright (maybe a bit less) than one for 1-2 hours, then continues to dim slowly for the next 3-4 hours.

    Hi Skiyk,
    congratulations on an interesting project. Allow me to discuss it for a moment.

    What you have to contribute:

    1) Your experiments show that two sheets of high-glow sheeting can maintain their luminosity longer than a single one;
    2) Once a prolonged glow is available, you have come up with ingenious ways to use it, and built actual prototype devices.

    Note that I am writing these as two separate points. Each of them has value in itself.

    Now I would like to comment one thing about Point 1: the sheeting you use was designed and made by people who wanted it to have certain properties. One of the parameters they must have spent some time thinking about is thickness. If your Point 1 is valid (and it sure sounds convincing to me), it might be equivalent to simply making the sheet twice as thick. If I were a manufacturer, I would ask myself these questions:

    1) Will Skiyk's devices sell?
    2) If so, do I want to be the one who sells them?
    3) If so, do I have to make them out of double layers of high-glow? Or can I get a thicker sheet of the same material that will have the same prolonged glow but cost less?

    I suggest an experiment:

    Get some glow-in-the-dark putty. Never mind if it is toy-grade or state-of-the-art NASA issue (as long as it's not radioactive). We want to check a physical principle in this experiment, not necessarily get a high performance.

    Flatten this putty into coin-sized disks of different thickness.

    Shut yourself with those and a flash lamp in a dark room, and have fun. Try two disks of equal thickness placed parallel, as in your idea. Try one disk twice as thick. Try as many other combinations as you can think of and care to use.

    This experiment should give you the answer to the manufacturer's Question 3.

    Good luck, and keep us posted,
    Leszek.

    Thanks Leszek, that is some interesting feedback that could really aid me in going for gold at the science fair!

    Also, I'm going to get a video of it working soon. I can't get a video of the regular sheet glowing (as I don't have it right now) but I will get one of the device as soon as I find my camera!

    UPDATE:

    Hello, it's been a while but I have not stopped. Here is an update.

    We made our own phosphorescent material that outperfomed the one we initially purchased.

    My initial Constant Charging Theory was PROVED after a series of quantitative and qualitative tests. It was substantial enough to be visible to the human eye, which is great.

    We have built every Device now and after a series of tests, our first design (the triangular one) proved the most successful.

    We are now rounding off our project by comparing our device to other ecolights.

    Thanks.
