minus-squareBussyCat@lemmy.worldlinkfedilinkEnglisharrow-up18·5か月前Supercritical CO2 has been looked at a lot for the Brayton cycle which can get 50% efficiency compared to steam that generally caps out around 34% The US and china both published studies talking about a brayton turbine but to my knowledge no commercial plants running off of it have been built yet

idk but you can also use molten salt
