Just depends on the system involved. 0F is WAY above absolute 0. It's quite possible to make a heatpump that works with a large temperature difference. It's not going to get a 20x factor like most, but I'm quite sure that you can make one that is > 1. -- Try my Sensible Email package! https://sourceforge.net/projects/sensibleemail/ _______________________________________________ Address messages to ev@lists.evdl.org No other addresses in TO and CC fields UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub ARCHIVE: http://www.evdl.org/archive/ LIST INFO: http://lists.evdl.org/listinfo.cgi/ev-evdl.org
