Can i get some thoughts and opinions on this persons work please, mainly regarding the vogel cut crystals, he seems to have a pretty legit scientific background and his experiments in later life sound pretty amazing if not a bit far out. im inclined to believe, there doesnt seem to be anything negative or fraudulent coming up in searches only good really, but no books by the guy and kind of forgotten about somewhat.
thanks nexus, heres a link i found about his work...
