But extraordinary claims and all that. It could be still be some sleight-of-hand fraud, though concealing a power source of such energy density or fooling those instruments would be quite a trick.

If you're going to complain about it, fuss over the setup or errors, not the tedious details that document the experiment (and provide a way for others to cross-check their practice and results later). Certainly there's the possibility for burying the truth in mounds of irrelevant data, but if your experiment hinges on showing that a resistor's load is larger than expected, I would expect to see some heavy details on how that was monitored.
