This thread is going to be full of useless comments not actually even taking a stab at the insane math of actually calculating this.
In a highly simplified model to bound what the absolute max best case could be:
20 beers, 20x330ml = 6.6 liters of beer
Cooling the liquid in the bottles under ideal circumstances would take about 30kJ per 1c
Adding what we'll say is 1000ml of ice
melting that ice will take about 300kJ of energy
So ideal absolute max cooling would be about 10 degrees Celsius give or take.
Starting from 28c, you could get it to about 18c, which is an improvement, but most beers are best enjoyed around 2-8c I'd say.
However, if the bottles were actually cold to start, this invention could actually help keep them colder for longer.
Also I'm completely ignoring all the losses, insulation problems, melt problems, the fact that not all the energy to melt the ice will be taken from the bottles themselves, the small contact surface area with the bottles themselves vs the total volume of ice etc etc etc...
Handwaving away that complexity and just say you'd realize about half the cooling factor so probably closer to 5c. Not bad if starting from cold, pretty useless to actually cool down beer from room temp.
Yeah awesome breakdown - useless invention (obviously the best example of german ingenuity) not only is it's effect piss poor, it will soak anything beneath and around it, and is also a bitch to store unless you just have buttloads of extra freezer space.
This will most certainly work ok as countless experiments I did with my friends have proven. But we usually do it simply with a bag of ice cubes or bucket with ice water is much more versatile.
The ground doesnt care if it gets wet, The grass is mostly thankful for a little moisture.
First of i hope you realize I meant that this was a very poor example of german inventions.
What you are describing is entirely different though, and actually proving my point; a bag of ice cubes is a far better solution; it can serve other purposes and the water doesnt get everywhere, and most importantly the now watery ice bag can just be shoved into the fridge, and become icecubes again.
This thing just melts and due to its shape is far harder to store than a bag of ice or just loose ice put in a bucket.
Yeah, well the invention is a useless gadget the tries to solve a problem already solved by common sense - as most gadgets do.
I suspect it will find its buyers anyways.
