    Interesting, but I don’t see it as practical anytime soon. It’s going to be expensive/hard seperating out the salt from the solvent, and even the paper’s author recognises as such.

    I wonder how Elastocaloric refrigeration compares, because that’s looking like a far more viable alternative.

    I wonder how long until we can efficiently convert heat into energy, instead of just moving it around and generating even more heat

      We already can convert a heat differential into electricity.

      Converting “just heat” into electricity is impossible though, that would break the laws of thermodynamics and create a perpetual motion machine. There is heat literally everywhere, even the coldest things we have made are not exactly 0K. So you could create electricity for free anywhere.

        The Carnot cycle is just for the Carnot engine. If we could use chemistry or quantum systems, it would have different efficiencies

          No really if you could convert heat to motion more efficiently than the (ideal) Carnot engine, you could have perpetual motion since the Carnot engine is reversible.
