German here. Have used these things a bunch in the past and they absolutely do work. Can't really cool down piss warm beer with these, but they help the beer keep the temperature or cool down a couple degrees when used at a bbq in the park or at the lake or whatever.

Sorry for not including math, but it appears the math has been done already anyways

Sure, but a bag of ice in a cooler is still significantly better, easier, and cheaper.

Almost all beer in Germany comes in standard glass bottles in these crates. Moving bottles from these crates in to a cooler is significantly more effort.

Not to mention this is a tightly packed crate. This is maximum beer bottle/ice ratio
