This is one of those design changes that both sheds more light on the wholeness, and requires a little bit of a different understanding of the theory and operation of the OTC-X1.
Simply put, the utrons are solid. They are conductive but not ferrous. They are lightweight however.
They work as inertial gyroscopes, and as electric coils. Electrogravity.
See the Construction blog to understand this, better. It is curious that they are lightweight, to me. But regardless, they are also charged electrically, and as such is a different type of accumulator.
Einstein's principles of Equivalence tells us all about how inertial forces are equivalent to gravity forces.
They have to be solid in construction to have enough mass behind them to exert a inertial and directed force, in the vortex configuration of the engine.
This is a design change, at least according to the information on this website; totally new to me, as I never even considered any gyroscopic implication because they were, in my mind, way too lightweight.
That open up many more avenues of exploration and possibility, however. Can they be constructed a little heavier, and shaped evenly -- the mass evenly distributed in the utron shape, and still remain non-ferrous?
Questions to ponder. But this seems to be the most logical purpose for the utrons, as an inertial generator, which is conductive to electricity.
This is what Carr was referring to as "electro-gravity." That aspect is not changed in design throughout the website, however. It is an easy matter to bridge the two concepts, and it will make a lot of sense as you read the parts of the website mainly dealing with electrogravity and Equivalence and the like.
If I could describe it simply, Through magneto-electrostatic resonance, it creates more of a force of inertial mass because it raises the frequency of that inertial acceleration throughout a static electro-magnetic field.
Electro-Gravitation
This is a very exciting new development to me. This has been a missing element, but a very obvious element all at the same time. Eventually, after seeing several spinning utron videos, it finally dawned on my thick head that "duh, they are supposed to spin." Actually it wasn't until I saw the next video after Walter's latest OTC-X1 video. That video was up next on the suggested video list that pops up on the video player about gyroscopic antigravity. That was when it really dawned on me. The fact that the video player just equated the two together seemingly randomly was testimony to my blindness and absolute short-sightedness as to what utrons are most logically doing in the OTC-X1. Walter immediately tested it, and confirmed that "yes, it could work." Walter Nowosad is a brilliant, and inventive man. His engineering knowledge is impressive next to his prominence as a renowned investigative journalist.
