Flopit, placed upon the ground, looked like something that had dropped from a Christmas tree, and he automatically made use of fuzzy legs, somewhat longer than a caterpillar's, to patter after his mistress. He was neither enterprising nor inquisitive; he kept close to the rim of her skirt, which was as high as he could see, and he wished to be taken up and carried again. He was in a half-stupor; it was his desire to remain in that condition, and his propulsion was almost wholly subconscious, though surprisingly rapid, considering his dimensions.英文原著 · 《Seventeen》
Fulton and Livingston met, probably at Barlow's house, and, in 1802, drew up an agreement to construct a steamboat to ply between New York and Albany. Livingston agreed to advance five hundred dollars for experimentation in Europe. In this same year Fulton built a model and tested different means of propulsion, giving "the preference to a wheel on each side of the model."* The boat was built on the Seine, but proved too frail for the borrowed engine. A second boat was tried in August, 1803, and moved, though at a disappointingly slow rate of speed.英文原著 · 《The Age of Invention》
From Edison's plant in 1903 came a new type of the storage battery, which he afterwards improved. The storage battery, as every one knows, is used in the propulsion of electric vehicles and boats, in the operation of block-signals, in the lighting of trains, and in the ignition and starting of gasoline engines. As an adjunct of the gas-driven automobile, it renders the starting of the engine independent of muscle and so makes possible the general use of the automobile by women as well as men.英文原著 · 《The Age of Invention》
"I don't need a balloon," returned the boy. "That's a clumsy way of traveling, at best. I shall go by electric propulsion."英文原著 · 《The Master Key》
