On entering a turbine plant on the ground floor, the attention is at once attracted by a multiplicity of pumps, accumulators and piping.
The motive energy was stored up in accumulators, and when these were discharged in succession, there was no means of re-charging them. Hertzog and Kritzinger, who had been relied on for this purpose, were not at hand; more than a third of the force with which De Wet had originally left the Doornberg had declined to leave the Free State; and the transport had been lost.
If such a launch were to run constantly, two sets of accumulators would be required, one to replace the other when discharged. This could be easily done, the floor being made to take up, and the cells could be changed in a few minutes with proper appliances.
I would sacrifice detail to modelling always, and the Baileys, it seemed to me, loved a world as flat and metallic as Sidney Cooper's cows. If they had the universe in hand I know they would take down all the trees and put up stamped tin green shades and sunlight accumulators. Altiora thought trees hopelessly irregular and sea cliffs a great mistake.... I got things clearer as time went on.
Her various weapons had stopped operating now, the hoppers of the Garnell guns exhausted, the charge of the accumulators aboard the ship down so low the proton guns had died out. "Lord they're taking the whole ship!" "Say Cole, is that any ship you ever heard of before? I don't think that's just a pirate!" "Not a pirate what then?" "How'd he get inside our detector screens so fast?
Indeed the storage battery has practically rendered safe the wide introduction of electric lighting, because a number of cells, when once charged, are always available as a reserve in case of any failure in the power or in the generators at any central station; and also because, by means of the storage cells or "accumulators," the amount of available electrical energy can be subdivided into different and subordinate circuits, thus obviating the necessity for the employment of currents of very high voltage and eluding the only imperfectly-solved problem of dividing a current traversing a wire as conveniently as lighting gas is divided by taking small pipes off from the gas mains.
The accumulators are, in this case, charged by a small high pressure steam engine, and a very large margin for depreciation and interest on plant is added. The launch taken for this comparison must run during 2,000 hours in the year, and be principally employed in a regular passenger service, police and harbor duties, postal service on the lakes and rivers of foreign countries, and the like.
It enables two cars to be run on the same line at once, and with a considerable saving of copper. To make the car independent of the conductor L for a short time, as in switching, a battery of accumulators B may be added and charged from the conductor, so that when the motor is disconnected from the conductor, the discharge from the accumulator may still work it and drive the wheels.
If so, and if enough batteries of accumulators are left intact to give them anywhere nearly full power, we can get an acceleration that will make a lifeboat look sick. Those main dirigibles, you know, are able to swing the whole mass of the Arcturus, and what they'll do to this one chunk of it we've got only a few thousand tons of mass in this piece will be something pretty.
Windmills are especially marked out as the engines which will be used to put electrical energy into the accumulators. From these latter again the power will be given out and conveyed to a distance continuously. High ridges and eminences of all kinds will in the future be selected as the sites of wind-power and accumulator plants.
