The SLT article on the peltier effect air conditioner was a bit short on details. I'm puzzled as to why this is considered a new or patent worthy invention, as peltiers have been discussed as airconditioning and refrigeration devices for years. The problem has always been the poor performance(10% of carnot?) of thermo-electric effect devices compared with compression cycle or absorbtion cycle coolers (40% of carnot). Is there any other more detailed information? njh 12:12, 5 August 2005 (UTC)
