    Great invention!!! It might be the last chance to get a NERD out in the sun!!!

    I think this technology - although pivotal and very significant - is still very much in its inception.......................A few years back I bought a "solar powered" wrist watch manufactured in Switzerland - - but it's performance was inconsistent, so I went back to one with a battery . . .cheaper and definitely always on time........................

    semperfi, I have a Japanese made solar watch (maybe that still means manufactured in Japan), it seems to do fine and has kept the time to the second. I haven't noticed any issues.... And I like the idea of the battery not running out at an inopportune time or having to replace the battery.

    Which reminds me. . . I should leave it out to make sure it is getting charged.

    Maybe ideal for Boeing 787s - they could use less batteries and charge them up in the clouds as they fly!

    These films can be used on any surface (buildings etc). A great add-on feature for a phone that no matter what allows you to recharge it in an emergency.

    WYSIPS can deliver around three milliwatts per square centimeter out in the sun or under artificial light. The company is hoping to double that figure in the next two years but at that current output, it comes out to about 232 milliwatts for an entire 3.5-inch display, such as on the iPhone 3G Sunpartner uses in demos.

    When Sunpartner debuted WYSIPS at CTIA in 2011, WYSIPS had reached 70-percent transparency and supplied around 5.8 milliwatts per square centimeter. As the transparency has increased, the amount of power conversion has decreased, but it still produces a good amount of energy.

    That’s the promise that WYSIPS carries with it entering into Barcelona along with the 95-percent transparency is has recently reached, making the layer nearly invisible on top of the display. “If this thing was good enough so that solar panel could at least negate the draining effect of leaving a phone on standby, I think that that could be in itself the value here,” Morgan of ABI said.

    On the iPhone 3G Sunpartner uses in its demos, the average 50-degree viewing angle on the device was enlarged to a full 180 degrees by placing the film inside the device. So the film could present a low-cost solution to improving the viewing experience on less expensive devices with lower quality displays that perform poorly when viewed at an angle. And DeBroca said that this effect can be applied in reverse as well to increase privacy, which could be seen as a definite plus depending on the manufacturer.

    Similarly, the film can get mobile phone users out of a fix when batteries go flat just when the time comes to pay a restaurant bill, or buy a train ticket.

    Uhh... why do I need my phone to pay a restaurant bill? Isn't that normally done in person?
