Abstract

Edison to T. Puskas: Since my letter of April 8th 1879 I have completed the standard generator which exceeds in simplicity and economy all geneators perviously devised by any one; Th size being less and from 88 to 90 per cent of the horse power applied is thrown into the form of current. Nothing more remains but the consturciton of the standard lamp, and the working up of the mechanical details of for a large central station. Thirty generators are now being made to start the station at Menlo Park for 500 burners with a radius of 1/2 mile, 300 lamps being placed in the streets and 200 distributed inthe eight houses on the Park. All provided with metres and the whole system worked as if in actual practice. About 4 to 6 months continuous running will be sufficient time after th esystem is started to eradicate all defects and prove beyond doubt the economy and practicability of the system for replacing gas as an illuminant.
