I recall reading somewhere that they are more commmon in Japan. I can't find the link of that page, but it led me to a conversion someone did from an old chest freezer. http://green-change.com/2009/05/23/chest-fridge-conversion/ http://green-change.com/2009/05/23/chest-fridge-conversion/ Based on their numbers it was ~10x more efficient.
