Yes, I'd say it's switching losses driving power dissipation, mostly, but also the amplification factor (often written as 60mV/decade). Bipolar transistors are still better at that. I haven't read the article yet, but I can imagine a chip with watercooling microfluidic channels, possibly also used to transmit informations (kind of like hormones in the bloodstream). If it is useful as a computing medium why not? Would it make a good waveguide too?
