No false claims have been made.Yes, there have. This is a false claim:
This method of isolation is quite different from a spring/mass isolation device.
It appears that we have different views of what a spring/mass system is.
Yes. And you should do a bit of research and learn just what they are.
By your definition just about any load carrying device using any type of suspension over a solid surface can be a spring/mass system. I guess this would include cars, motorcycles, etc, and of coarse the Levitator.
Any mass coupled to a spring creating a resonant mechanical low-pass filter for the purpose of vibration isolation is a spring/mass isolation system. And yes indeed, the suspension systems of cars and motorcycles as well as the Levitator are EXACTLY that.
I guess to you a new Corvette is simply a load carrying device or maybe just transportation.
I would call a Corvette a Corvette. I would call its suspension system a spring/mass vibration isolator.
At least kuribo has called it a spring/mass/damper system. This at least encompasses another function of the device.
Again, the presence or absence of damping does not change a spring/mass system into something other than a spring/mass system. The method of isolation is EXACTLY the same; that of a mechancial low-pass filter.
If you need to be so broad in your definitions then the Levitator can be a spring/mass system.
The Levitator is a spring/mass system even in the narrowest sense. Again, the presence or absence of damping doesn't change that fact. Even a literal mechanical spring spring/mass system has damping. That's inevitable due to the fact that there's no such thing in the realworld as a frictionless spring. Any amount of friction results in damping.
My contention is this broad term does not adequately categorize the Levitator or define its functions. It is much more than just a load carrying device and you know it. It is also unique in contrast to other isolation systems.
It's function is that of a spring/mass isolation system. At no time did I say it was simply a "load carrying device" so please stop putting words into my mouth. And it's only unique in its implementation. It's not at all unique in terms of its method of isolation.
I also contend that it is superior to a literal spring in that it is not directly coupled like a spring.
I suppose you would like to debate that too?
Yes, I will debate that becuase it is indeed directly coupled. The top plate is directly coupled to the bottom plate via the stabilizing pins. There's no way to avoid mechanical contact between the pins and the top plate as any static array of magnets is inherently unstable as per Earnshaw. So to claim that there is no direct coupling in the Levitator is simply false.
My guess is you would not call it a debate or discussion. You would contend that any person whose views are not in parallel with your own makes false and erroneous statements if you can by definition prove some fault?
These aren't my views. They are the views of well-established physics. So you're not arguing with me. You're arguing with a large body of science which quantified much of this centuries ago.
I am sure everyone appreciates the job you do here of being the truth police.
More I hope than appreciate the erroneous claims and other misinformation you've been trying to pass off.
Loose the attitude Steve. Life is too short.
Lose the denial, Danny. Life is too short.
