I’m not too sure I buy into the idea of a phone which you can carry with you. But the folks at Popular Science thought in 1947 that this was a good idea – at least good enough to get an article about it.
Engineers and trainmen can keep in constant touch with their own crews or talk with the crews of other trains with the Ã¢â‚¬Å“Carry -phone,Ã¢â‚¬Â a portable telephone announced by the Pennsylvania Railroad. The device uses railroad tracks or wires as its communication channels, but transmits and receives messages through the air by induction, using a large metal loop.
So, what do you think?Ã‚Â Could people ever decide to carry around phones to help them keep in touch?
