Electric Propulsion Reality Check

I wish there was a fridge that would limit cooling during the on-peak price period.

Peak electrical use is when people are home in the evenings, from 3pm-9pm. Since this is when people are going to be opening the fridge, this is also when you will be losing cold air inside the fridge. Perhaps fridges could be made with some kind of cold reservoir that could be chilled when the electricity was cheap and keep the unit cold when it is expensive?

The idea of access charges is nothing new. My mother used to have to pay for access to city sewer even though her home was on a septic system.
