Ring-pull mobile telephone. Designer Christopher Jung (born 1969) talking into a prototype of his ring-pull mobile telephone. This battery-free tel- ephone never needs charging from a mains supply. Pulling the cord (by the ring-pull at the left of the telephone) a few times charges a generator in the disc-shaped telephone,which provides power for over five minutes of talking. He is speaking into a yellow pull-down microphone. Dialling is done on the yellow keys around the disc's edge. Also,speaking a name into the microphone causes it to automatically dial their number from its address book. Jung designed this award-winning device while at University of Berlin,Germany | |
