All knotted up

Saw an advert today for fireplaces that "add warmth to your room without adding heat". They look like fires but don't heat up, just to have the look of an open fire. In the spirit of 'Not The Real McCoy', we were thinking of some other inventions to add to the NotFire. How about a NotFridge, for those who want somewhere to store food but don't like it chilled. Or a NotComputer, guaranteed not to compute? (oh, hang on, got one of those already)
