I don't think there are any hard & fast rules, besides that which we produce to govern ourselves.
Mother nature is a "hippy chick with muddy feet" as Ken Wheeler (Apophasis) puts it.
I favour this analogy as it defies the strictness in "mainstream" science and its unwillingness to comprehend the open questions that surround them. Instead many seem to find solace (and oftentimes an income) from beating a very dead horse ..
("
it's not possible to do what we aim to achieve")
One should consider all the potential reasons for there still being
no global access to a fully looped OU generator design, when we know the principles involved can yield such a result ..
(
countless examples)
Perhaps there exists / has existed systems that are not reducible to a Whr. / COP function, such as orgone accumulators, or similar technology that has yet to be "officially" investigated but as far as I can tell, if a given OU system has useful surplus output, it had ought to be possible to compare it against the input, provided the meter exists for the particular energy flow in mention.
Any physical system which has a sustained and observable di polarity had ought to be able to produce useable force in some way. Correct implementation of appropriate geometry is what fundamentally allows a re-gauging event to occur, tmk. (Paying for a lack of, or something akin)
Whether that's physical Euclidian / non Euclidian / Hyperbolic geometry in a mechanical design, or the connections and lack thereof which allow for electrostatic currents to be induced in a solid state or rotary design. Or anything else tangible.
I'd guess that Tesla was able to achieve what he could, mostly through
visceral foresight.
He like a few others who live today, must have been able to conjure a schematic in meticulous detail in his head, no CAE required, and according to Dollard, could then run it for months to "note the rate of bearing wear"
Since any given invention arrives via the Brain, this is the tool we should look to hone, improve and vary the use of IMO, Sadly few seem to do so in a truly effective manner..
Masters who know the secrets can often use pitifully inadequate equipment to produce stellar results, because
they know, that they know, what it is that they're doing.
There are so many incredibly skilled people working on these designs that, I conclude, we must be very close to an unveiling by now; it's almost painful to consider the situation given what we
know ..
How can you keep 8Bil. in the dark ??
There is relatively very little interest in this topic despite the ramifications.
That alone should speak volumes to an enquring mind
