Metal that conducts electricity but not heat

[phavoc]

Another interesting science discovery - metals that conduct electricity but not heat, which are an apparent violation of well-established scientific laws. Science is always bringing us new data!

Vanadium dioxide is not a metal, it is a metal compound and you wouldn't expect it to conduct heat very well. Moreover the Wiedemann–Franz law applies to metals, not metal compounds.

Vanadium dioxide electrical conductivity is at the semi-conducter range until it reaches a critical temperature, at which point its conductivity increases dramatically.

I am surprised that the researchers would claim to have confounded a 'law' that doesn't apply to semi-conducting metallic compounds.

That is a pretty poor article.
