Yeah, I saw it too- the tube is a rather sheer braid, and the person
going thru it can spread out their elbows & knees to slow down, suck in
to speed up. The bottom twenty feet gets a bit tighter to slow the
person down for landing, but I see several problems with this-
* a very long elastic tube can stretch significantly, so that you have
to struggle out of the last thirty feet of tube on the ground, a very
* fire resistance would be nil
* it requires at least a little skill on the part of the passenger
A steel cable, harness, and reel with dynamic brake as Spike mentioned
would be far better. High rise fires, once out of control, always trap
people above them. Spike's addition of oxygen bottles is unnecessary,
though- there are fire hoods available on the market now that would be
sufficient for a few seconds passage through a flame. Incorporate this
into a nomex overall...
