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.
Yes, they say this does away with the need for compressors or refrigerants.
"This cools by using electrons to move heat through specialized semiconductor materials, eliminating the need for moving parts or challenging coolant liquids."
Yes, that's a Peltier device by definition. The efficiency of them as of now are not great, so the big news here, if reproducible is that they've refined a process that gets them up to 70%.
Huge if true.
