Not illustrated. 1888 Excerpt: ... and you can draw on that store, to illuminate your house, just when you please, and how you please. I may mention, in passing, that Mr. Edison has just invented a very simple apparatus to measure the amount of current that comes into your house: thus you will only have to pay for what you get. And Sir William Thomson has invented an apparatus which, of itself, will cut off the current as soon as your battery is fully charged: thus you will only get what you want, and none will go to waste. It may be observed, too, that if you desire a more than usually brilliant illumination, for some festive occasion, you have but to order a few extra cells and hire a few extra lamps. Again, let me take the case of a small country town, with a waterfall near at hand, or a strong flowing stream. The energy of the falling water can be converted into an electric current, at hardly any cost, by means of dynamoelectric machines. Then, if a large storage battery is provided for the illumination of the streets, and if each house has its own small battery for private use, the energy of the stream during the whole period of twentyfour hours can be stored up to light the town during the hours of darkness. A greater store of electrical energy will be wauted, of course, in winter than in summer, as the period of darkness is longer; but Nature happily provides for this increased demand by giving us, in winter, a stronger flow of falling water. The Storage Battery as a Motive Power.--As a motive power, these storage batteries seem eminently fitted for driving tram-cars. An ordinary tram-car, with its full complement of passengers, weighs about four tons. To drive this weight, at the rate of six miles an hour, we should require an electro-motor working at about three or four horse-power...
