>Never said they break the laws of thermodynamics.

true, you said "gaslight thermodynamics", which i have no idea what that means, so i took a guess at what you were implying.

>never be more efficient than alternatives such as... Bigger nuclear reactors.

is efficiency really the only metric to be considered? i feel like available space, availability of alternatives, time to complete construction, etc. are worthwhile to consider.

>And how long have you been out there? Have you never seen investors dumping and wasting billions in dead-ends? Never seen a mania before?

considering the length of time and sheer number of people, companies, and governments worldwide considering/investing in SMR tech it seems unlikely to be a mania. but i am not an expert. you are talking like you are one, which is why i am asking questions.
