Solar Powered RFID, Solar Paint
Solar Powered RFID Tracking
Lockheed Martin subsidiary Savi Technology has begun deploying solar-powered Radio Frequency Identification (RFID) readers and signposts, saving energy and negating the need for installing electrical infrastructure in remote areas.
Designed for use in the defense and commercial sectors, the solar-powered signposts activate RFID tags attached to vehicles or pieces of equipment.
Solar Paint Yields Cheaper Power
What does Google invest in? (also named Popular Science's Innovation Of The Year)
NanoSolar produces its PowerSheet solar cells with printing-press-style machines that set down a layer of solar-absorbing nano-ink onto metal sheets as thin as aluminum foil, so the panels can be made for about a tenth of what current panels cost and at a rate of several hundred feet per minute.
With backing from Google’s founders and $20 million from the U.S. Department of Energy, Nanosolar’s first commercial cells rolled off the presses this year.
