This is certainly thinking outside of the box...realistic and astounding...

      GIVE ME A BREAK! This theory is over about 100 YEARS old!(very old movies showed it for all sorts of things, and lasers were often discussed later.) They started using it commercially around 40 years ago, and it REALLY started to take off about 30 years ago. So WHERE do they use it? Laser printers, remote controls(as HE said), fiber optics, etc....

      But how do they protect it? HIS example was direct! He even SAID it had to be direct! And how do they localize it? And it is only ONE WAY. Laser printers, and usually remote controls, are one way. Fiber optics are a tad more complicated, and get rid of the need for direct placement through the fibers. Actually, that is ALL the fibers are for.

      AND, of course, my keyboard, mouse, and remote controls use light. How will his light affect them?

    This sounds like a great idea. I'm just wondering how often you'd have to change the bulbs, do you have to configure each new bulb you replace, and how much? Also, you'd maybe have to buy all new lamps and holders for the light unless they are the same sizes. Finally, the wiring would have to be changed in every house and building to fiber optics to accomodate data to the actual light bulbs correct?

    Sounds expensive, very expensive, but once in place, would lead to a world of difference.

    @Sunfyre7896 -

    I think the way they have it figured, the chip is a separate part from the actual light source - it looks as though the receiver does the translation...the light carries the stream in the visible spectrum -

    This may be beyond fiber optics as we now know it...

      But if the data is sent through a chip, wouldn't it be using radio frequency from there? It said that light cannot travel through walls, so the light bulb would have to send the signals it is reading through a line that can accommodate light as is the case the other way around when it receives the data. What if the room had no windows, the light would have to get the data somehow using light waves. I would assume you'd have to have something like fiber optic light lines to each individual light bulb.

      Maybe that is something you were saying but the way I took it was that you meant that the chip got the signal somehow and then translated it to the bulb, which then transmits it through a light wave. To me this would be like having a 2 inch exhaust from your engine itself but then halfway down the exhaust pipe, you change to a 6 inch exhaust pipe. You can still only get as much exhaust out of the engine as the 2 inch will allow despite having a 6 inch for the last half of the pipe.

    Yes Steve...this theory was discussed 100 years ago...this video just showed it in a working form...an actual and possible application...

    And as Sunfyre7896 supposes, there may be some things about transmission, translation and point of origin not fully discussed (I for one, would certainly like to see more on how the transmission is accomplished)

    But, you bring up an interesting point about duplex, and how you would upload data into such a stream, and how easily it might be interfered with.

    I see what you are saying sunfyre...It seemed to me they were explaining it as the chip would translate from the light source, and not the chip to the light source...the data stream may be an open source, like a world-wide web stream, then to a browser, and you connect to it. Once connected, it is could be governed pretty much the way it is now...(or if we are not careful, more governed) Like he said "LI-FI" - like Wi-Fi , only more easily available and accessible...

    Who knows? It could be all just smoke and mirrors...we can't even get Wi-Fi as we know it to work in some respects as a "free-range" product.

    But this certainly sparked my interest when I saw it...

    I just hope it's open the way the modern internet is. With SOPA trying to stifle the internet, opening the door to government censorship and regulation, virtually a patriot act of the internet, it would be easy for them to just say, 'for safety' that they're regulating the new data transfer and internet within that country's borders the way China does.

    Yup - there is even a Harvard Law professor now that states it is a clear violation of 1st amendment (as if we did not know that already) and even if passed, it will be in challenged in court forever - (or until we have martial law or a confirmed Plutocracy, whichever comes first...)

    I know someone will say it eventually...:rolleyes: so - i'll give the pun-ishment -

    I hope some of our "esteemed warrior colleagues" who are engineers in wireless data transmission can (here it comes) "shed a little light" on this subject -

    If they have seen or read any info, and links to same...

    Even as simply as it is explained, it is boggling...in an OSI network engineering sense -
