It is very different to make a practical system and to introduce it. A few experiments in the laboratory would prove the practicability of system long before it could be brought into general use. You can take a pipe and put a little coal in it, close it up, heat it and light the gas that comes out of the stem, but that is not introducing gas lighting. I'll bet that if it were discovered to-morrow in New York that gas could be made out of coal it would be at least five years before the system would be in general use.
Thomas A. EdisonFooling around with alternating currents is just a waste of time. Nobody will use it, ever. It's too dangerous . . . it could kill a man as quick as a bolt of lightning. Direct current is safe.
