Wyttenbach, as it was already written, Bohr and Mills pictures are excluded by electron capture ( https://en.wikipedia.org/wiki/Electron_capture ) - the fact that nucleus can capture electron from orbital, what requires this electron to get to a distance nuclear force can start acting (femtomemters).
There are also many other problems like the nature of this membrane - a very controversial infinitesimal made up entity.
Until you can explain electron capture there, please let us stay away from this theory here.
Regarding being "easy to understand", I don't know how this membrane applies, Gryzinski is just Kepler + magnetic dipole moment of electron + quantization condition.
ps. please help defending his Wikipedia article: https://en.wikipedia.org/wiki/…on/Free-fall_atomic_model
