Every hour, the sun floods Earth with more energy than the entire world consumes in a year. Yet solar power accounts for less than 0.002 percent of all electricity generated in the United States, primarily because photovoltaic cells remain expensive and relatively inefficient. http://www.physorg.com/news175195934.html Nanotechnology Mon, 19 Oct 2009 18:32:55 EST news175195934 (AP) -- The smell of manure hangs over Greeley as it has for half a century. These days it's more than just a potent reminder of the region's agricultural roots and the hundreds of thousands of cattle raised on the city's outskirts. The stench smells like an opportunity. http://www.physorg.com/news175017016.html Technology Sat, 17 Oct 2009 17:00:02 EST news175017016 America's power grid today resembles the country's canal system of the 19th Century. A marvel of engineering for its time, the canal system eventually could not keep pace with the growing demands of transcontinental transportation. http://www.physorg.com/news160942405.html Technology Thu, 07 May 2009 19:14:19 EST news160942405 Since its debut in 2007, the Flip video camera has turned millions of people into filmmakers by providing a foolproof way to shoot videos and upload them to the Web. http://www.physorg.com/news160827769.html Electronics Wed, 06 May 2009 11:23:32 EST news160827769 (PhysOrg.com) -- Certain fish species blend with their environment by changing color. Sandia National Laboratories researchers have demonstrated that, in theory, they could cause synthetic materials to change color like fish do. http://www.physorg.com/news159198454.html Nanotechnology Fri, 17 Apr 2009 14:47:58 EST news159198454 Some of the tiniest solar cells ever built have been successfully tested as a power source for even tinier microscopic machines. An article in the inaugural issue of the Journal of Renewable and Sustainable Energy (JRSE), published by the American Institute of Physics (AIP), describes an inch-long array of 20 of these cells -- each one about a quarter the size of a lowercase "o" in a standard 12-point font. http://www.physorg.com/news145197611.html Physics Thu, 06 Nov 2008 12:40:11 EST news145197611
