If you or your family members have a nasty habit of leaving the refrigerator door open for extended periods, you may wish to invest in some Fridgeezoo pets. These carton-shaped creatures live in your fridge, greeting you as you open the door. If you leave the door open for too long, however, the Fridgeezoo population will scold you relentlessly.
Each time you open your refrigerator door, cool air escapes and room-temperature air enters, which raises the internal temperature of the fridge. Some $1.7 billion dollars' worth of energy is wasted each year in the U.S. due to fridge doors that have been left open for too long; a device like the Fridgeezoo could significantly lower that sum.
