Molten salt will vary depending on its heat capacity and delta_k above freezing point.
0.338048298841 MJ/liter for the typical NaNO3 KNO3 NaNO2 mixture (assuming a delta_k of ~300)
53.356955169699994 MJ/liter for something like CaCl2 45.5682%, MgCl2 54.4318% (Ionic halide, assuming a delta_k of ~1568)
In the future I expect even higher delta_k for molten salts.

- VBprogrammer 5y ago> assuming a delta_k of ~1568 I think we can go ahead and rule that out as impractical given we're talking about temperatures which are high enough to melt steel.

I don't think steel will be used as the only form of confinement (certain kinds of ceramics come to mind can handle it now[0]), so agree to dissagree.
