Elastocaloric coolers are not new. There are even some versions that you can buy right now, they usually for niche industrial use and have their own set of problems, namely that they're not remotely as efficient as vapor compression so it costs more and moves less heat.
The breakthrough here was discovering a different alloy that allows sub-zero temperatures. It doesn't change the efficiency which is the primary barrier to adoption.
Wait, they are talking about a new type of peltier device?
Just a regular heat pump, but bending metals instead of compressing gasses. Same principle though.
