Definition of economic development

Now as the alternate system is rapidly spreading all over London and also in many parts of the kingdom, this is a question which interests us directly. Are we running special risks by permitting its establishment? As far as lighting currents of fifty or one hundred volts are concerned, it certainly matters little or nothing whether they are direct or alternate, for neither will produce any serious injury on the human frame. When it comes to currents of distribution of two thousand volts, then it is quite conceivable that death is more certain by the alternate current, but unfortunately it is also fairly certain with the direct current, so that there is very little to choose between them. A house in which the fittings were charged to such a potential would be as dangerous as a battlefield. What is wanted is sufficiently good workmanship to prevent contact ever being made between the distributing mains and the service wires, and this there should be no difficulty in obtaining. Even if a leak should occur the device of putting the service main to earth at one point will prevent it doing any harm. Brown refers to two cases in which men definition of economic development were killed by contact with definition of economic development a perfectly insulated wire, their death being caused by the static charge. We feel considerable doubt as to the possibility of any one being killed by a static charge under these circumstances; we prefer to believe that the insulator was bad, probably a mere taping of non-waterproof material. Just as the death-rate on a railway varies inversely as the perfection of the signalling appliances, so the fatalities in America from electricity will decrease as better materials are adopted, and more care is expended in erection.--Engineering.
