Show ESSAY electricity will Dit displace place other motive powers tho the following is a worthy effort of john S barber a stude student t in the class of prof E L J macewan MacEtti an of the agricultural college by electric itys displacing other motive is is meant that it will be used in the future as a motive power more than any other powers such buch as aa bleam wind and water just na as steam has displaced other motive powers in ill the past it will be superseded by electricity electricity is superior to all other motive powers it can be manipulated more easily and with greater rapidity generally all that needs to be done to set the machinery in motion is to press the butice on the electric street cars tb motorman has only to turn a crank and in a few seconds the car is running at a high rate of speed electricity can be transmitted greater distances from its source than any other motive power the greatest distance through which steam can call be profitably transferred iia S about six or seven hundred feet and A iid this is done only at a great losi lole of energy through the cooling of the steam the other powers power cannot be transmitted nearly so s far ae steam electricity by means of the present existing apparatus pa paa ratus ius as a has been estimated can be through a distance ot five anve hundred miles with a loss of only about twenty five fire per cent ot of Us its siergy A As s the distance de crease ro io i o the loss of energy de ciensi B s very few industrial cities or cities where industries could be established if motive power were to he had a die i e 0 remote from a sou sourie re of energy that a aia ire five hundred miles in length will not reach them As early as 1891 an electric current of horse power was transmitted transmit t bitted led from lafflen to the frankfort exposition grounds a distance of miles electrical power is much less expensive than other powers nearly all electric plants if not all are run by water power which is entirely useless as a power generator in its natural course these plants arp are situated as a rule several miler mile above the city or other places that they furnish with electricity tri city and in places where other industrial plants could not be built the water that furnishes the electric plant with power ast as it on down into the city can be utilized in other it has been estimated that steam power can be produced produce Ll at about 50 00 per horse power per annum the great niagara company can furnish electricity right at the plant tor lor 1800 for each horse power per annum thus we see a marked difference in the price of these twe powers by the converting of steam into electrical eberg a great saving of effective energy may be realized this has been demonstrated by scientific experiment nikols tesla teala one of the greatest inventors of electrical machinery and the discoverer of the rotating magnetic field by which all dynamo m machinery a is run has invented a new electrical motor this is known as the tesla motor by means of this motor power stations are dispensed with the electricity is generated by the steam itself mr tesla has demonstrated expert mentally that with the same fuel he can easily produce twice as much effective energy and under favorable conditions three times as ae much E electricity has another ad advantage vanta ge over other powers it can be produced from any other power known the potter of the wind can be utilized in producing electricity tri city wind mills can be located in places where the wind Is ia most regular and certain this energy can be con erred into electricity el e c which can call be transmitted by means of wires to the places where motive power is if required water power can call be easily converted c orl into electrical energy water wheels can call be placed into the st streams reauis and the electricity electric electricity it generated be transmitted retransmitted to locady licali I 1 ties where it is used innumerable ate arc the electric plants throughout the country wo we have two right herein the small emali city of logan steam bleam power the grea greatest tet of all

from this great cataract it is estimated that over the niagara escarpment t cubic feet of water plunge downward a distance of feet for each second of time expending over horsepower horse power of

to mention iny more for we are already awre aware of the fact S the coal and wood supply which furnishes the greater parti of the motive power of the loyld at the rate of con 01 not last very many centuries longer the amount of luel fuel consumed each day in the tha world A is enormous thick of the millions million of locomotives which draw the trains of commerce the huge ocean steamers which are as frequent on oil the sea as railroad trams trains on the land and the innumerable manufacturing fac turing establishments all of which are daily consuming vat vast amounts of fuel fael think too of the millions of families in the world which are consuming great amounts of fuel to say nothing of the great fires which sweep through the large forests of every country countr A de destroying inestimable amounts of timber with every increase of population this bonsu consumption emption inevitably evit ably increases when this supply of fuel is exhausted what can furnish the power for carrying on the industry of the world nothing will be done but to use the greatest of all motive powers electricity so we see that other motive powers will not only as a natural consequence but will of necessity be displaced by electricity LOGAN march 1 31 11 1896 |
