Somehow I don't think so.  Did all inventions in the early 50's defy the laws of physics?  Firstly, in order to keep the tea pot at a reasonable hot drinking temperature (say 60ºC, the Kozy would have to have been too hot to touch.  Secondly, the "enveloping" nature of the Kozy would have heated the handle just as much as the tea, making it impossible to pick up.  Come on guys, this is not even near the mark!
