Zero-wasting the cold: Does anyone ever freeze blocks of ice outside in the winter and let them defrost in the fridge/freezer? (dubvee.org)

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.

Along these lines...

We ex-wife and I had a horizontal freezer her folks gave us. We lined the bottom with rows of bottled water, filled it over the tops with the garden hose, put our frozen groceries on top. We had a freezer that would easily last 2-weeks if a hurricane knocked us out, and plenty of clean water. Plus, being "thermally full", it took less power.
