I'm going to ignore your ignorance on this one, I have several years in electrical resonant research and development, as does my brother. We have over 100 members in our study group, which spans the globe, and has been in operation for about 5 years proving what you say is BS. Many new energy saving/producing products will be hitting the market soon as a result of some of our members hard work.
That's a strong "yes" on your belief in pyramid power then; shame Neptune is cubes.
"it's called resistance" and it could increase with load to a possibly significant level on a low voltage DC circuit; that's the reason your supply is AC at a much higher voltage thus effectively eliminating the problem. You can argue that resistance does still increase with load and that's true; just not to a remotely significant level on an AC mains supply.
There is
ZERO chance that any variations on the AC supply will make it through a modern switch mode PSU and have am impact on the DC output; you couldn't be more wrong.
"the magnetic field induction which moves the current"... just no.
