- Editor's Notes
- "After duly apologizing for thus ocupying your time, I beg to ask you a question, believing you to be the most capable person of appreciating my claims. ### What is your opinion of an invention or contrivance which will, when placed in the circuit of a dynamo, cause that dynamo to do twice the amount of work or result which it would otherwise do. In other words; if my apparatus is placed in the circuit of a 125 light dynamo, it will cause it to light 250 lights. This would evolve no additional expense, either in the horse power required to drive the dynamo, in the attention necessary to keep it running or any other way, except a slight unapreiable increase in the original cost of the plant, perhaps $10, for each dynamo used. It is equally apliable to any dynamo, whether an Edison, Brush, Thompson-Houston, or any other type. It is not caused by chemical action. It merely utilizes a certain portion of the current usually waisted by the dynamo. ### Providing that I could show you to your satisfaction a contrivance capable of doing the above, would you personally be willing to pay $5,000 in cash and 50 per cent of the future profits, (or 50 per cent of the shares of a company organized for the explotation of this invention), for the controll of its sale an manufacturing, or do you believe that you could introduce me to a person or corporation who would do so, in which case of course I should be happy to allow you if desired, a convenient commission. ### Awaiting your reply I have th ehonor to subscribe myself." Respectfully yours, E.A. Hernandez [Marginalia: "Tate The modern dynamo account for 96 per cent of [unclear] applied to it. This being the case where is the power you propose giving to come from. Refer him to J. H. Vail"
