theres a large amount of space on the other side of the fridge for a battery, perhaps large enough to fit an old EV battery mounted vertically

i like to think that a skilled composites designer looked at a far more bare bones version of this and decided that they were the ones who made the slick white shell and completely integrated the unit, just something they wanted to do in their much freer life, and maybe a jab at the old corporate history that they can say “hey! its not just corpos that can make sleek, good looking appliances!”
