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.

Answer to strange question :

What is the energy absorption-dissipation of a ZEC  chute for a 100 or 300 feet installation ?

Answer:  It should be obvious for anyone having  engineering or architectural training,  that  ZEC-ME's unlimited height capacity  only results of the stacking of mechanically independent single floor unit modules ... just like a stairways.

ZEC-ME works because the system is obviously discontinuous and  freely interconnected concentrically. Ergo ... basics physic shows that relevant safety parameters such as :

a. Energy absorption/ dissipation. b. Complex effects of tribologic factors involved  in the friction  breaking effect ... are limited  to the HEIGHT of ONE FLOOR  and the MASS  is limited by the number of people that potentially can fit in a ZEC chute unit  of in average  ONE FLOOR eight  ( about 10 to 15 feet or 3 m< 4.5 m).
A 200 stories ZEC-ME installation will shows not mechanic problem different  from  them relevant  to a  4,  20 or 30 stories installation.

Fast speed!
Answer: Many fires safety specialists yet believe  that  ZEC-EM  large mass evacuation capacity is based on sliding down people at high speed   ...   Beliefs and scientific facts are not the same things.
Experiencing the system before opposing nonsense discriminatory  arguments should be considered.
The speed is similar to stairway ... The space occupation factor makes the difference.

After 25 years of having being certified and  million times tested in Europe ... It could be a matter of professional ethic for the "popes' of high rise  evacuation in the USA to officially  test  the ZEC-ME under academic supervision.
The Zephinie multiple entry escape chute technology is now a commune technology for 10 years..

In matter of science and technology  xenophobic discrimination,  prejudgment and sleazy defamation are right protocols for testing new alternative technologies ...    

If there a problem of theoretical  understanding ... Testing the system should have been for years a matter of  ethic procedure for those having the official  responsibility to secure public safety and involved building evacuation consulting  services ... 

If the other escape chute systems  present fundamental incompatibility for tall building mass evacuation...
that is not our problem .... engineering competence is supposed avoiding confusion.



Testing the system would avoid wrong question.
