I think all of my criticism also applies to the Vixra paper.
I would add some comments about the section 11.0. The Dirac equation isn't a valid wavefunction equation. The ZB arises because the equations misleading mixtures positive and negative energy solutions. The Dirac equation is correctly interpreted as an identity for the fermion field operator in field theory, and the normal ordering procedure separates positive and negative solutions, eliminating all ZB components.
Hestenes' work is incorrect.
