[N198001], Technical Note, Thomas Alva Edison, May 10th, 1882

Editor's Notes

"Experimenting on reducing iron sand to iron also mixing with coke, charcoal, etc & tar, crude pet. Mould in brix and heating sufficiently to consolidate." "Thermo Experiments" "discs of Cu & Ger Sil alternated heating one end causes heat travel to other end and there is a gradual fall of heat until the other end is scarcely hotter than the atmosphere. By using several thousands of these discs an exceedingly novel & economical conversion of heat into Elect is obtained" Another thermopile arrangement after this. Then: "Today we run the Electric Railway with 3 machines in series each working its own field independent of the other as shown on next page"
