Of course he is. For instance, he's claiming (if your representation of those claims are accurate) that classical electromagnetic interactions (exchange of photons) between the electron and the configuration of the double slit apparatus causes the interference pattern in the single-electron double slit experiment. Classical electromagnetic physics predicts no such thing (yes, there are interactions, but no, they would not produce the observed pattern), which is why that experiment is considered a significant "proof of concept" experiment for quantum mechanics.
Oh contraire, classical physics can indeed describe such patterns. Look at chapter 8, particularly Fraunhoffer diffraction. Then google it. Fraunhofer diffraction occurs when a wave goes through a single aperture. It forms discrete bands. This is from the interaction between the EM field of the wave and the aperture and is well described classically. Now when there are two or more apertures things get much more complicated, but the end result is the so called interference pattern results. It isn't really interference but is caused by the interaction with the wave with the aperture, and superposition with other waves from other apertures.
It's more important what he hasn't done: an experiment to prove that his theory is correct where its predictions differ from current prevailing theories. For instance, showing a double-slit-like interference pattern in an apparatus where the electron can only pass through a single slit, but the material surrounding the slit is arranged to mimic the electromagnetic behavior of a double slit. Perhaps use a pseudo-slit of a thin layer of a low-permittivity material. (Electrons accumulating on the nonconductive pseudo-slit surface would be a complication, but one that could be dealt with in many different ways for a single-electron system.) Or if not that, something else gleaned from the thousands of pages of theory he's written. Something that can be demonstrated in a real experiment.
The only attempt Mills has made to verify his theories in such a way, the only prediction he's actually made and attempted to verify, is the predicted production of excess energy in commercially useful quantities via the conversion of hydrogen to hydrino in a wide variety of different reaction conditions. And that verification has failed for thirty years.
It hasn't failed for thirty years. Rather, verifications have been successful for thirty years. Having verified excess energy and having excess energy that is commercially practical are two very different things.
