Curious if this would have any noticeable energy savings. Basically thinking of taking old semi-disposable plastic containers (the ones that like deli meat, butter, etc come in), freezing them outdoors, and letting them defrost (absorb heat) in the fridge/freezer. Basically back to the “ice box” model.
Anybody doing that and/or have any results to share? Mostly curious if it would be worth the effort.
I use them in my ice chest when bring home groceries from the city. Even in the winter here it will be in the teens or twenties at night it can get into the 50s during the day.
