    We had an earlier topic in which Cold Fusion asked a perfectly valid question:

    The thread was hijacked by the usual idiot, which led to some pitiful flame-tossing by folks who should know better. Nobody bothered to give Cold Fusion a respectable answer. No one even tried. So I will respond to the actual question by Cold Fusion.

    The components of ordinary soda-lime glass do not contain any atomic or molecular bonds that can absorb light's frequencies. That is, the energy levels of the normal electron transitions in glass do not match any of the frequencies of visible light.

    This is not a coincidence. The earliest glassmakers searched for the right ingredients of the right purity to ensure this key transparency property for glass.

    Note also that light is not totally unaffected by its passage through glass. The light is slowed down and we see refraction, the amount of which is determined by each frequency. I hope that helps, CF.


    Now friends, if the Village Idiot shows up (count on it!), do us all a favor and DO NOT RESPOND! Ignoring him will not make him go away. Just don't make things worse by encouraging his rebuttal. Thank you.

    Did you miss my posts or something? Did I not provide this information? Anyway, point taken about the VillageIdiot.

    Sorry, it must have gotten lost in the mess. No offense intended.

    What frequencies does normal glass react to? Is it possible to have glass react to gamma radiation? How did ancient glass makers know what materials to use? Thanks for the responses SteveF and Kalster.

    Ordinary glass is fairly resistant to UV radiation. Lead glass is used for gamma shielding. And even though lead glass is called crystal, that's a misnomer. No glass is crystalline.

    Well the idiot is back with a legitimate question for you. If glass does not absorb light, how does it penetrate the glass. I can spray a garden hose through a washcloth, some water is absorbed and some is passed through and it will come out in a stream much like it went in.


    If you look at glass from an angle perpendicular to lights passage through it, you can see the radiation. From that side. So I sincerely submit that glass certainly absorbs light.

    I believe what you meant to say was that glass allowed light to pass through glass. Which to me is first absorbing it.

    I would love to have these interesting conversations face to face with you guys. I am always interested in meeting such bold souls whose only intent is ultimate truth.


    Sincerely,

    It likely only absorbs some light because of impurities and the fact that it is always hard to create the ideal component that we seek.

    Here to me this looks like absorption, and very strange refraction. I noted some things that don't add up while doing experiments with laser beams. Light and laser light, seems to travel very much like electricity through a conduit. Wanting only to leave the other end of the conduit. At whatever angle it strikes the end of the conduit.

    Where can you get glass like that?

    This is a man made substance, however glass performs similarly.

    This stuff I have I believe is called prismatic plastic. It creates a spectrum of light, like a glass prism.

    They use it in lighting to get some wild effects.

    It is just easier to work with. And if you drop it, it does not shatter.

    I am forever working in the dark with thousands of volts, to supply my lasers, and it is easy to break glass.

    I usually get zapped when I forget there are capacitors in the power supply that hold current even when it is unplugged or disconnected from the battery. I kind of like it now. Ha-ha.


    If you want a piece I will send you one.

    My theory on this laser zig zagging, based on the all electron universe is that, those rays you see inside the prismatic plastic. Are leaving the structure. In the inferred band, unknown radiation band or heat band.

    This would explain how the fiber optic cables were causing so much heat over miles and miles of run. If you think about the minute input wattage. And the fact that the phone company had severe over heating problems with the original system.

    Over heating that lead to bacteria problems, this would explain how it was possible.

    Here is a video I made of a high voltage laser. Shining through that same prismatic plastic. You can see that it does not zig zag when fired across the bar perpendicular to the bar. Yet anywhere on the end and it zig zags.

    You really should not move a high voltage laser by hand, especially in the dark. If only because you might get popped and startled and fall or trip in the dark.

    If you have to in the name of science just use good common sense. Clean things off the floor. Don't run outside in the rain to get a camera from your truck. And then use the laser. Things like that.

    And do not look at these rays. They can cause eye damage. I work with very high power welding equipment. And I rarely have any trouble or eye fatigue wearing the proper equipment. However these devices have caused me some eye stress, in a matter of seconds. Especially in the dark.

    Sincerely,

    Here are two experiments that show something rather wild. In my opinion.

    I am sure that the radiometer works because, the black side accelerates electrons away from the black side of the flags. The white side is slowing electrons as the leave.

    So when you apply a powerful magnetic field that is allowing electrons to flow into the magnetic field. By creating a shortage of electrons near the magnet. The radiometer works in reverse.
    I tried this many ways from all angles. And it is the same. I even spun that radiometer in the normal direction and the magnet stops it and turns it the other way.

    I still have another experiment that will help confirm this. I am going to try a similar experiment with all white sides on the Radiometer flags to see if there is a difference.

    http://www.Rockwelder.com/Flash/Magn...Radiometer.htm

    This movie below is showing how an AC powered radiant heater that puts out some inferred rays, turns the radiometer as light does. The heater is a dull orange color, and you can see in the reflection off the radiometer bulb, that it is in fact a dull orange. The camera just picks it up as white, or yellow.

    http://www.Rockwelder.com/Flash/Radi...Radiometer.htm

    A black light also turns the radiometer as light does.
