Err.... I doubt it. In General Systems Theory terms they
are the same, albeit using a different language. 8-)
But you've got me googling so I'll get back to you when
I've thought about the implications a bit more.
One memorable factoid I came across -
========================================
Many hysteretic systems make screeching
noises as they respond to their external
load (hence, the natural connection with
hysteria).
========================================
It also answers the thermodynamic objection as to
where the energy in WaterFuel [you ought to trademark
that word ;-) ] is coming from.
Go round the hysteresis loop one way and you put energy
in. Go round the other and you take energy out. The
energy is coming from the Beta-atmosphere which is the
d2L/dL and d3L/dL2 Compreture (i.e. gas "heat" - see
#504 post of Beta-atmosphere Group) equivalent as far
as the water is concerned.
On the subject of the 8th power Casimir Law.
For the benefit of Vorts who don't read the Beta-atm.
Group posts, I wrote in #507
=======================================
The 4th power Casimir Law is confirmed
experimentally with flat plates.
Presumably one would have to confirm
the 8th power Casimir with a cylinder
which could have a variable diameter.
I was pondering how one could do this
and thought perhaps that one could have
three long elliptical cams which
rotated to confine a different sized
space.
=======================================
It would seem that with their nano-cylinders
the LLNL team have done that for us,
albeit unknowingly. 8-)
Cheers,
Frank
