Tom Swift and His Electric Runabout | Page 4

when I read that account in the papers of the Touring Club, offering a prize for the best electric car, it occurred to me that I might put my battery into an auto, and win."
"Hum," remarked Mr. Swift musingly. "I don't take much stock in electric autos, Tom. Gasolene seems to be the best, or perhaps steam, generated by gasolene. I'm afraid you'll be disappointed. All the electric runabouts I ever saw, while they were very nice cars, didn't seem able to go so very fast, or very far."
"That's true, but it's because they didn't have the right kind of a battery. You know an electric locomotive can make pretty good speed, Dad. Over a hundred miles an hour in tests."
"Yes, but they don't run by storage batteries. They have a third rail, and powerful motors," and Mr. Swift looked quizzically at his son. He loved to argue with him, for he said it made Tom think, and often the two would thus thresh out some knotty point of an invention, to the interests of both.
"Of course, Dad, there is a good deal of theory in what I'm thinking of," the lad admitted. "But it does seem to me that if you put the right kind of a battery into an automobile, it could scoot along pretty lively. Look what speed a trolley car can make."
"Yes, Tom, but there again they get their power from an overhead wire."
"Some of them don't. There's a new storage battery been invented by a New Jersey man, which does as well as the third rail or the overhead wire. It was after reading about his battery that I thought of a plan for mine. It isn't anything like his; perhaps not as good in some ways, but, for what I want, it is better in some respects, I think. For one thing it can be recharged very quickly."
"Now Tom, look here," said Mr. Swift earnestly, laying aside his papers, and coming over to where his son sat. "You know I never interfere with your inventions. In fact, the more you think of the better I like it. The airship you helped build certainly did all that could be desired, and--"
"That reminds me. Mr. Sharp and Mr. Damon are out in it now," interrupted Tom. "They ought to be back soon. Yes, Dad, the airship Red Cloud certainly scooted along."
"And the submarine, too," continued the aged inventor. "Your ideas regarding that were of service to me, and helped in our task of recovering the treasure, but I'm afraid you're going to be disappointed in the storage battery. You may get it to work, but I don't believe you can make it powerful enough to attain any great speed. Why don't you confine yourself to making a battery for stationary work?"
"Because, Dad, I believe I can build a speedy car, and I'm going to try it. Besides I want to race Andy Foger, and beat him, even if I don't win the prize. I'm going to build that car, and it will make fast time."
"Well, go ahead, Tom," responded his father, after a pause. "Of course you can use the shops here as much as you want, and Mr. Sharp, Mr. Jackson, and I will help you all we can. Only don't be disappointed, that's all."
"I won't, Dad. Suppose you come out to my shop and I'll show you a sample battery I've been testing for the last week. I have it geared to a small motor, and it's been running steadily for some time. I want to see what sort of a record it's made."
Father and son crossed the yard, and entered a shop which the lad considered exclusively his own. There he had made many machines, and pieces of apparatus, and had invented a number of articles which had been patented, and yielded him considerable of an income.
"There's the battery, Dad," he said, pointing to a complicated mechanism in one corner
"What's that buzzing noise?" asked Mr. Swift. "That's the little motor I run from the new cells. Look here," and Tom switched on an electric light above the experimental battery, from which he hoped so much. It consisted of a steel can, about the size of the square gallon tin in which maple syrup comes, and from it ran two wires which were attached to a small motor that was industriously whirring away.
Tom looked at a registering gauge connected with it.
"That's pretty good," remarked the young inventor.
"What is it, Tom?" and his father peered about the shop.
"Why this motor has run an equivalent of two hundred miles on one charging of the battery! That's much better than I expected. I thought if I got a hundred out of it I'd be doing well. Dad, I believe, after I improve my battery a bit, that
