The rescue system according to claim 1, further comprising a cable guiding roller arranged on a portion of the building to guide said cable to the outside of the building. 11. The rescue system according claim 1, further comprising a belt or harness coupled to the person being rescued, and which is connectable to the free end of said cable. 12. The rescue system according claim 1, wherein said fan blades are dimensional such that the maximum falling speed of the person being rescued is less than about 12 meters per second and more than about 4 meters per second. 13. The rescue system according claim 1, wherein said fan blades are dimensional such that the maximum falling speed of the person being rescued is about 8 meters per second. 14. The rescue system according to claim 1, wherein the materials of said frame, air fan and cable cartridge are fire proof and can perform with no failure in temperatures up to about 600° C. 15. A rescue system for rescuing occupants from high floors in high rise buildings, comprising: a frame positioned adjacent an open or openable escape portion of a building, the escape portion being open or openable to the outside of the building; dynamic resistance means for creating a resistance to a gravity force acting on a person to be rescued, said dynamic resistance means having a shaft coupled thereto, said shaft being mounted to said frame such that said shaft is rotatable relative to said frame to drive said dynamic resistance means; and a removable and replaceable cable cartridge comprising a rotatable housing which is removably coupled to said dynamic resistance means so as to rotate said dynamic resistance means upon rotation of said rotatable housing, and said cable cartridge having a cable pre-rolled on said rotatable housing, said cable having a free end which is connectable to the person to be rescued; wherein when the person to be rescued goes out from the escape portion of the building, a falling motion of the person causes the cable to move with the same speed as the speed of falling of the person, thus causing said rotatable housing to rotate which in turn causes said dynamic resistance means to rotate and to create a resistance to the falling speed, until the falling speed of the person reaches a substantially equilibrium value when the resistance force created by said dynamic resistance means is equal to the force of gravity acting on the falling person. 16. The rescue system according to claim 15, wherein said cable has another end which is connected to said rotatable housing. 17. The rescue system according to claim 15, wherein said frame is fixed to a building structure. 18. The rescue system according to claim 17, wherein said frame is fixed to the building by one of screws, bolts or pins. 19. The rescue system according to claim 15, wherein said cable cartridge and said dynamic resistance means have respective mutually engagable members which mate so as to prevent relative rotation therebetween. 20. The rescue system according to claim 19, wherein said mutually engagable members are in the form of a square, a hexagonal or a triangular shape. 21. The rescue system according to claim 15, wherein said rotatable housing of said cable cartridge and a shaft portion coupled to said dynamic resistance means have mutually engagable members which mate so as to prevent relative rotation therebetween. 22. The rescue system according to claim 15, wherein one of the cable cartridge and a shaft portion coupled to said dynamic resistance means has at least two pins extending therefrom, and the other of said rotatable housing of said cable cartridge and said shaft portion coupled to said dynamic resistance means has holes for receiving the respective pins. 23. The rescue system according to claim 15, further comprising a safety coupling device coupled to at least one of said cable cartridge and said shaft portion coupled to said dynamic resistance means to secure the non-rotatable connection between the cable cartridge and said shaft portion. 24. The rescue system according to claim 15, further comprising a cable guiding roller arranged on a portion of the building to guide said cable to the outside of the building. 25. The rescue system according claim 15, further comprising a belt or harness coupled to the person being rescued, and which is connectable to the free end of said cable. 26. The rescue system according claim 15, wherein said dynamic resistance means provides a resistance such that the maximum falling speed of the person being rescued is less than about 12 meters per second and more than about 4 meters per second. 27. The rescue system according claim 15, wherein said dynamic resistance means provides a resistance such that the maximum falling speed of the person being rescued is about 8 meters per second. 28. The rescue system according to claim 15, wherein the materials of said frame, dynamic resistance means and cable cartridge are fire proof and can perform with no failure in temperatures up to about 600° C. 29. A method of rescuing occupants from high floors in high rise buildings using an apparatus, comprising: a frame positioned adjacent an open or openable escape portion of a building, which escape portion is open or openable to the outside of the building; and a dynamic resistance device having a rotatable shaft; the method comprising: (a) providing a plurality of removable and replaceable cable cartridges, each comprising a rotatable housing which has a cable pre-rolled on said rotatable housing, said cable having a free end which is connectable to an occupant to be rescued; (b) removably coupling said cable cartridge to said rotatable shaft of said dynamic resistance device so as to rotate a portion of said dynamic resistance device upon rotation of said rotatable housing; (c) connecting said free end of said cable to the occupant to be rescued; (d) causing the occupant to be rescued to go out from the escape portion of the building, whereby a failing motion of the occupant to be rescued causes the cable to unwind from the cartridge and to move with the same speed as the speed of falling of the occupant to be rescued, thus causing said rotatable housing to rotate which in turn causes said portion of said dynamic resistance device to rotate and to create a resistance to the falling speed, unlike the failing speed of the occupant to be rescued reaches a substantially equilibrium value when the resistance force created by said dynamic resistance device is equal to the force of gravity acting on the falling occupant to be rescued; (e) removing the unwound cable cartridge and removably coupling a new cable cartridge to said dynamic resistance device; and repeating steps (b)-(e) to successively rescue additional occupants. 30. The rescue method according to claim 29, wherein said cable cartridge and said dynamic resistance device have respective mutually engagable members which mate so as to prevent relative rotation therebetween. 31.
