Of the two the latter seems to me the better way, for then the safety is absolute, unaffected by any possible combination of circumstances which might render even a low-potential appliance dangerous to life and property.
In other cases, where a small amount of alternating current is required on the transmission line, it has even been found economical to take direct current from a large unit, change it by means of a rotary transformer into alternating current, step up from 80 to, say, 2,000 volts, go to the distant point, and step down again to 80 volts alternating, and then convert again by means of a rotary transformer into low-potential direct current.
ARJILLAX. High what? PYGMALION. High-po-tential. The Life Force is not so simple as you think. A high-potential current of it will turn a bit of dead tissue into a philosopher's brain. A low-potential current will reduce the same bit of tissue to a mass of corruption.
