One Cooling Off Thing: Air Conditioners That Cost Much Less

Researchers may have found a way to cool things off indoors and even outside using half the energy of typical air conditioners.  The system is one in which rectangular ceiling or wall panels contain chilled water that circulates inside them. When a person stands next to one of these panels it cools them off because heat tends to naturally move from a hotter surface to a colder one by radiation.  Thus the body heat of a person standing under or beside the panel radiates toward the colder panel.  According to one of the developers, because the “Cold Tube” system can make people feel cool without dehumidifying the air around them, so it cuts up to 50% of typical air conditioning energy consumption.  And it also works outdoors.  Cool!
