[D8822AAK], Letter from William Eltruigham to Thomas Alva Edison, April 6th, 1888

Editor's Notes

"I wish to draw your attention to the following few lines. [unclear] occupation is that of a stationary Engineer, which capacity I have been in for eighteen years. About one month ago, I had an idea that electricity could be brought in abundance from friction of steam. ### I began to experiment on super heated steam above the surface of water on the boiler. With this pressure at fifty lbs to the [unclear] and let the steam off [unclear] to come in contact with an apparatus I had constructed. And the consequence was that a great deal of elecricity was given off. ### I then increased the pressure to eighty lbs to the sq inch and could touch working that the steam came in contact with us the electricity was so heavy. I still put pressure 25 100 lbs. & took a bar of [unclear] eight feet long and one inch in diameter and I could bring the flame clean to the end of it. And every place the steam came in contact with if I touched it with a piece of steel it would give a heavy flame. And as I do not know anything about electricity, I have been advised by men of Prominence who I have shown it to, to write to you concerning it. The [unclear] is the electricity scatters so much I do not know how to bring its to one point to make a continuous light. ### If you think there would be anything in this and for cheapness it looks reasonable that it would, I would be please to communicate with you." TAE marginalia: "Say that he will find full description of steam engine battery in Ganot physics. E."]
