Thermal energy stored for decades without lossesscience.orf.at 5 pointsjhoechtl1 year ago1 commentSaveHideCopy link On HNComments−ggm1yI suspect it's a giant version of those hand warmers which do enthalpy when you snap a thing inside the bag. Phase change stuff.Not sure what's novel here. Maybe its some small specific increment of efficiency.Heat storage in "salt" is a common pathway. Salt being a generic word not sodium chloride specifically.Almost anything in the "other phase" state is by definition stable for years without loss unless it sublimated. Ok, explosives aside..(Not a chemist or a doctor or lawyer or engineer so there's that. Corrections welcomed)
