These are just Peltier cooling mechanisms highly refined it seems. If they've increased the efficiency enough that a full-sized refrigerator can keep food cool without refrigerant or a constant electrical signal, that's huge. AFAIK Peltier coolers still need some electrical input, though minimal.
I'm calling bullshit. There's no way a Peltier element can exceed the coefficient of performance of the refrigeration cycle, at an affordable price, without turning the room into a hothouse.
Their findings were published in the peer-reviewed journal, Nature.

I'm not questioning the findings. I'm questioning the article, and your interpretation to arrive at such a summary.
It's all potential, and possibilities, and future projections. I'm sure someone will find real world applications for it, but a fridge tacked out with Peltier tiles that draws energy from its ambient environment (while actively ruining the thermal gradient by the way) is ludicrous.
