    Nanoantennas on plastic sheets can produce electricity from IR heat....!






    Flexible Nanoantenna Arrays Capture Solar Energy

    Researchers have devised an inexpensive way to produce plastic sheets containing billions of nanoantennas that collect heat energy generated by the sun and other sources. The researchers say that the technology, developed at the U.S. Department of Energy's Idaho National Laboratory (INL), is the first step toward a solar energy collector that could be mass-produced on flexible materials.
    While methods to convert the energy into usable electricity still need to be developed, it is envisioned that the sheets could one day be manufactured as lightweight "skins" that power products such as hybrid cars or iPods with potentially higher efficiency than traditional solar cells. The nanoantennas also have the potential to act as cooling devices that draw waste heat from buildings or electronics without using electricity.
    The nanoantennas target mid-infrared rays, which the Earth continuously radiates as heat after absorbing energy from the sun during the day. In contrast, traditional solar cells can only use visible light, rendering them idle after dark. Infrared radiation is an especially rich energy source because it also is generated by industrial processes such as coal-fired plants...........continued in article




    This is pretty awesome, they could use it as underlayment on roofs and collect the IR heat energy during the day and at night for electricity, plus they could cover the back of solar thermal panels with it. They could also use it as backing for solar electric modules and since they would cool the conventional silicon cells it would improve the output of them plus add electrical output to the system from the heat..... My laptop gets super hot on the bottom so having that on the bottom would help conserve battery power...

    no sign of despair in their hair, nor their hearts
    but oh they have yet to be experienced and that makes aging so very worth it...ML circa2012

    Spray-On Solar-Power Cells Are True Breakthrough

    I thought it would be in stores by now.

    That's a different technology using Quantum Dots, the trouble with these are that they need to control the power with nano rectifiers so that we can get the voltages and amperages and freqs. to a level we would use in batteries like 1.5V, 3V, 9V and 12V etc....

    Yes, that's the "..with further advances.." form the 2005 article, IMHO. I could be wrong but I think good things come from waiting and waiting ... much longer than initial excitement makes you think. I'm still waiting for practical jet packs, flying cars for the masses, and a manned Mars mission that sounded just around the corner in the 70's.

    Well, at least I'll have Bigfoot proven tomorrow.
