Merely subtract the previous reading from the last one, which will give 45, or the number of kilowatt-hours from which the bill for electricity is computed. If electricity costs 3 cents a kilowatt-hour, which is the price charged in some localities, the bill should come to 45 X .03 or $1.35. Before stoves for cooking came into use in the home, food was cooked in open fireplaces.
"Pirates in ships faster than light fifth order rays nullification of gravity mass without inertia ridiculous! Proved impossible, over and over again. No, sir, if pirates are operating in space and it looks very much like it they won't get far against a good big battery full of kilowatt-hours behind three courses of heavy screen, and a good solid set of multiplex rays.
Through the great room the two Lewistons swept at full aperture and at maximum power, two rapidly opening fans of death and destruction. Here and there a guard, more rapid than his fellows, trained a futile projector a projector whose magazine exploded at the touch of that frightful field of force, liberating instantaneously its thousands upon thousands of kilowatt-hours of stored-up energy.
It will be observed from the accompanying illustration that the dial on the extreme right has the figures reading in a clockwise direction, that is, from right to left, the second one in a counter-clockwise direction, or from left to right, the third one in a clockwise direction, and the fourth one in a counter-clockwise direction; also that above each dial is indicated in figures the number of kilowatt-hours that one complete revolution of the hand of that dial registers.
READING AN ELECTRIC METER. An electric meter, which is similar in appearance to a gas meter, consists of three or four dials, which are placed side by side or in the shape of an arc. The numbers on the dials represent kilowatt-hours, a term meaning the energy resulting from the activity of 1 kilowatt for 1 hour, or 1 watt, which is the practical unit of electrical power, for 1,000 hours.
From the forward end of the strange craft there erupted prominence after prominence of searing, unbearable flame as the terrific charges of explosive copper struck the mark and exploded, liberating instantaneously their millions upon millions of kilowatt-hours of intra-atomic energy.
One gram of lithium hydride would give nearly fifty-eight kilowatt-hours of energy in one blast. A pound of the stuff would be the equivalent of nearly seven tons of TNT. In addition, it was a nice, clean bomb. Nothing but helium, radiation, and heat. In the early nineteen fifties, such a bomb had been constructed by surrounding the LiH with a fission bomb the so-called "implosion" technique.
"Once a con man, always a con man, is my belief." Captain Lacey rubbed his hands together. "Ed, tell me something. Didn't it ever occur to you that a battery which would do all that a battery which would hold a hundred kilowatt-hours of energy in a suitcase would be worth the million he was asking for it?" Colonel Dower looked startled. "Why ... why, no. The man was obviously a phony.
