Now that is the coolest fridge I've ever seen. Found a video of it in action (yes, featuring the same dad joke all over the comments but that is not stopping me): https://youtu.be/RoGuvvzHY1A?t=416

That entire place is mind-bending.

Mind-bending indeed, but looks pretty impractical. In an ordinary fridge, if your egg carton is a bit out of place, your door may not close properly. In this one, you're going to have liquid omelette slathered all over the place, and how do you even clean the bottom of that thing?
Who, apart from Americans, puts eggs into the fridge?
Any country where eggs are industrially washed before showing up in grocery stores.

Their protective coating (called the bloom, I believe?) goes away when that happens, and they become susceptible to salmonella when they stay at room temperature.

What's the reasoning behind washing eggs to make them more susceptible to salmonella?
Because it cleans the poop off.
So if an egg has poop on it, it's less likely to have salmonella?
Many British people and Australians, even though our eggs are sold at room temperature and unwashed. I don't know why, but for most of us it 'feels wrong' to store eggs anywhere else.
Well, it's a prototype. Any production model would need to watch for fingers too, so it'd have to be gentle.

Just as elevator doors won't crush a person due to sensors and such.

The cleaning part is an interesting question.

The idea is nice, but one thing I use a refrigerator for constantly is putting rectangular things in there. A box of cake, half of the lasagne left over in its oven dish, various containers, et cetera. Even cartons of milk and yoghurt have a square or oblong horizontal plane. Those round shelves are ideal for cilinders with a small diameter; bottles of condiment and beer, basically.
That's a very cool fridge. But how much difference does that make in practice?

Air doesn't have much mass, right? How much energy does it actually cost to cool the air in a fridge? (vs the solid parts of the fridge, and the food)

Looks like the OP's fridge uses 10-20x less power than a typical fridge, is that entirely due to the air not spilling out?

Mostly yes. Upright fridge and freezer designs trade off efficiency for convenience (rooting around in a chest fridge/freezer can be annoying). https://youtu.be/CGAhWgkKlHI
Depends a lot on humidity. Condensing a fridge full of humid air releases a fair bit of heat.

Also a fuller fridge will have much more thermal mass and care less.

But yes, exchanging the entire air volume of a fridge every time you open it is very energy-wasteful.
