It seems to me that the authors are pretty cautious.

They don't claim "we found a scalable way to violate the second law of thermodynamics", but instead make very specific claims about what they measured, and that they produced 94 nano-Watts per square centimeter. They don't even mention entropy.

This feels more like they know exactly how unbelievable their results sound, and that they are very careful to not overstate anything.
