Would this be similar to what TinMan is observing?
I know this is somewhat old but still applies?
The thing I would like people to consider is that W.B. Smith stressed there is along with a magnetic and electric field, one more field referred to as the tempic field. These three fields compose what he termed the Field Fabric.
I agree it may sound like a crazy idea, but what if he is correct? Best I could tell, there was no motivation for him to say this and in fact, by saying it, probably was fairly detrimental to his career. So one has to ask themselves, could this be truly how the universe is wired. If it is, then most all of our formulas and laws of electromagnetic induction/propagation are missing a key aspect to their full and complete operation or mechanics.
The tempic field then is associated with time and entropy. And if you consider we have three dimensions to organize space, why not three fields that occupy space. Next, consider the magnetic and electric fields; they can be manipulated. Is there any reason the tempic field cannot be treated the same. Seems to me if we really are able to understand these principals, constructing a device that utilizes them should be well within our capability. It's easy to dismiss a time machine as science fiction, but this may only be true when we limit our exploration to just two fields of force. When we add the third field, not only does it become quite possible, but rather obvious.
I think the magic is all in the geometry. If one puts the right pieces in the correct places, we can unlock a whole new world of discovery. Somehow Brad's putty coated toroid core does this. If we look at it in a conventional sense, it will be too easy to dismiss. If we look at it as a device someone like W.B. Smith would have been interested in, then we have a chance to see how it may really work and make significant improvements to it.
