Science News Solar energy nanoantennas are created Published: Aug. 11, 2008 at 11:23 AM WASHINGTON, Aug. 11 (UPI) -- U.S. scientists say they have created flexible plastic sheets containing billions of nanoantenna arrays to collect heat from the sun and other sources. The researchers at the U.S. Department of Energy's Idaho National Laboratory said the sheets might one day power everything from hybrid cars to iPods. The scientists noted the nanoantennas also have the potential to act as cooling devices that draw waste heat from electronics without using electricity. "Every process in our industrial world creates waste heat," said physicist Steven Novack, who led the research. "It's energy that we just throw away." The nanoantennas' ability to absorb infrared radiation also makes them promising cooling devices, Novack said. Since objects give off heat as infrared rays, the nanoantennas could collect those rays and re-emit the energy at harmless wavelengths. The researchers said such a system could cool buildings and computers without the external power source required by air conditioners and fans. The study that included INL engineer Dale Kotter, W. Dennis Slafer of MicroContinuum Inc. and Patrick Pinhero, now at the University of Missouri will be reported Wednesday in Jacksonville, Fla., during an American Society of Mechanical Engineers conference on energy sustainability. upi.com
