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)

Somebody with writing talent should modify the section about how efficient a peltier is. The real efficiency is not so cut and dry as it is made out to be in this article. A peltier (TEC) is more efficient as voltage decreases. When you get down to about the 20%-of-maximum range, a typical commercial TEC is more efficient than even traditional phase change often is. A TEC at 20% will typically move ~5.7W of heat for every 1W emitted as heat in the device's own operation. At maximum voltage, that same TEC might move 0.5W of heat for every 1W it emits as heat. —Preceding unsigned comment added by 72.24.104.194 (talk) 15:34, 10 April 2008 (UTC)
