article actually seems to cover all this issues well (except maybe for ‘your claims are lies’), so I’m hopeful about this one.

  >liquid-CO2 system has a round-trip efficiency of 75-80% You mean this part? Edit: this is pretty much theoretical Carno cycle and it has moving parts

    I think even 60% efficiency would still be fine if the storage was cheap enough and scales well. Just build more solar cells or wind mills to compensate the inefficiency. Neither lithium-ion nor gravity based systems seem particularly scalable to me. So a good-enough system that’s scalable will be a winner in the long run I think.

    That's for heat conversion, no? This isn't about heat.
