People that were trapped above the floor levels impacted could have
been evacuated by only one set of four or five units of ZEC-EM, remaining
operative over 25, in few minutes.
The Zephinie Escape Chute (ZEC)
can operate over 100 floors.
Can evacuate up 1000 persons per minute, including handicapped ,
injured persons with the same average escape speed.
Ignorance or bad will
can't invalidate demonstrable
facts.

Thirty years of conformism to special interests has barred the potential
of commercialization of the only high rise alternative mass evacuation
technique in the USA.
Misunderstanding the design's
particularity that makes the Zephinie 's multiple entry evacuation
module an unlimited height mass evacuation technique lead to non-sense
question and unfair judgments.
The Zephinie's Multiple Entry evacuation module IS NOT mechanically a
single continuous evacuation system but a series of one floor modular
escape devices.
So, eventually thinking that under Galileo and Newton physic laws it
could occur some physical difference on the ZEC-ME evacuation parameters
between 3 stories and eventually an 120 stories installation should not
be a serious idea for anyone having learned engineering or architecture
science.
The included illustration will
try to explain that a ZEC-ME module performances and limits are
independent of any other interconnected ZEC-ME units. Such as could be
independent a one floor length hook ladder from another similar ladder
(fig 3) or a stairway's floor unit (fig 4) the physical performances and
limits of a ZEC-ME installation is only related to the characteristic of
a single standard ZEC unit... No matter if we have 3 stories, or we have
a 300 stories building.
Mechanically a ZEC per floor unit will have to absorb/transforms the
potential of energy of about a mass limited to 200 kg over a vertical
height in average of 3.5 meters.
The potential energy transformation
occurring in a ZEC-ME is about 1700 w/s. The two sleeves give an area of
110,000 cm2 for dissipating said 1700 w/s giving an energy load to
dissipate of about 0,05 watt second or 180 Joule per cm2 of chute
fabric. (Back in 1968 it was a matter of concern. Since over one
millions ZEC evacuation experiences have confirmed that we know how to
manage the problem. We have set proprietary evaluation methods of heat
effects) Please see note #1
So if three stories ZEC-I module installation works fine, a ten, thirty or
hundreds stories installation will work the same way using a classic
logical scientific extrapolation. However, another problem arises from
presuming of any scientific competence, when bad faith is involved ...
to judge a life saving technology badly needed for years by the honest
American having a not special interest in fire safety deals.
Ignorance that the system works, and how it does works, remain the
privilege of the newspapers' favorite top American specialist in
evacuation, .
So... it is ignored that 2/5
stories demo structure ZEC-ME have been 100,000's times publicly tested
oversea for decades. Stubborn ignorance will not erase facts known by
millions of witness in Europe and other countries.. ZEC-ME system allows
an effortless, precise and complete control of motion.
No equation can explain human's feeling.
Some day thousands American will personally experience the ZEC mass
evacuation technology. Some day it will be impossible to hide anymore to
the American public opinion the special interest biased motivations
having motivated key players of the NY safety regulation about
forbidding innocent people evacuation.
After making the intellectual efforts for understanding that a 100 floor
ZEC-ME installation is made by interconnecting 100 "mechanically"
independents ZEC-ME units ... just working like every single steep of a
stairway.
A stairway steep will carry always the same limited number of persons..
no matter the height of the building, the mechanical parameters of steep
are same.
High speed motion and eventual dissipation of potential energy conversion
is obviously related with an erroneous idea of how eventually works the ZEC-ME
The following intellectual effort
to adjust with reality, is to try understanding that a ZEC-ME in an
emergency evacuation situation is saturated ( like a stairway) by the
disproportion of the number of entry versus the single exit capacity of
the ZEC sleeve. No matter either if the extreme limit can reach 3600
people/hour for a 65cmdiameter system (2ft). As soon as the ZECZEC-
sleeves are saturated it result from a slow motion the ZEC-ME
installation.
The vertical speed range in the .3<1m/s (1/3ft/s)
no much different that stairway descends speed but resulting 3 times
faster because we use a vertical path and stairway a helicoid' path.
Of that results that thermal dissipation is a far less matter of concern
than the tensile efforts transferred the sleeve and inertial overload.
So the breaking load of 14 tons for the support sleeve's payload of
about 200kg . ( margins exceeding elevator industry safety standards)
Training for using ZEC-ME : the low
speed motion in case of mass evacuation makes absurd the objection that
public will not know to use the ZEC in case of severe emergency.
En masse evacuation occurrence a complete ignorance of how the system
works is not a problem. However, it is a problem in case of using the
ZEC-ME when the installation is empty.
Note # 1.
Thermal dissipation:
We have three different specific heat material and constant micro motion
in the textile components. Strong electrostatic effects and pressure
differential effects produced body motion in the ZEC sleeves.
The two "independent" sleeve's system presents still unique design
advantage over any other vertical evacuation devices for smoothly
transferring the breaking effect between the body in translation to the
sleeve support due to a unique "form effect" resulting of the
particularity of the low module elastomer used in the design.
A mathematical model remains
extremely complex to work out:
The ZEC "form" effect would require extremely complexes tribological
analytic works to be evaluated compared with straight surface friction
effect.
The particular "form" effect also complicates mathematical
interpretation considering the lows module synthetic elastic material
reaction that produces the friction effect. The material present complex
electro-molecular potential energy storage including time "hysteresis"
phenomena and temperature effects.
Zephinie invented a particular testing device in 1976 to better evaluate
the safety margins considering particular phenomena occurring in cloth
material.
Most of the complex physical phenomena were considered in the thousands of
tests of the different ZEC evacuation models (1973-1976).
Including strong UHF field on the ZEC storage were considered.
We have proprietary methods to monitor the ZEC sleeves physical
parameters.
Our 36 years experience to represent the original source of competences
in the matter of modern vertical mass evacuation.
