Mine shafts on the point of being closed down could be used to provide geothermal energy to local towns. This is the conclusion of two engineers from the University of Oviedo, whose research is being published this month in the journal Renewable Energy. The method they have developed makes it possible to estimate the amount of heat that a tunnel could potentially provide. http://www.physorg.com/news167913013.html Technology Mon, 27 Jul 2009 11:50:01 EST news167913013 (AP) -- The toucan's colorful bill gives new meaning to the phrase cool dude. Indeed, that gigantic schnoz turns out to be a radiator the rain forest dweller uses to lose body heat. The bill of the Toco Toucan makes up about one-third of its body length and ornithologists have long wondered about the purpose for the appendage. http://www.physorg.com/news167584608.html Biology Thu, 23 Jul 2009 16:17:23 EST news167584608 (PhysOrg.com) -- Open any computer and you're sure to see at least one massive cooling device, complete with metal fins and a noisy fan.
