Excerpt from Compressed Air: A Reference Work on the Production, Transmission, and Application of Compressed Air; The Selection, Operation, and Maintenance of Compressed Air Machinery; And the Design of Air Power Plants Compressed air and electricity to-day share between them the great field of power transmission, to the practical exclusion of all other transmission agents. Steam, because of its rapid condensation, can hardly be considered as a practical power transmitter for any but the shortest distances. Hydraulic transmission has had no general application. Mechanical means of transmission, such as shafts, belts, ropes, chains, and gears, are necessarily very limited in their possibilities. Compressed air and electricity, on the contrary, offer almost unlimited possibilities of extension and of diversified application; and in all cases, where properly applied, they are entirely successful when measured by the modem standards of commercial economy. With the relative merits or shortcomings of compressed air and electricity as power-transmitting agents, the pages following have nothing to do. Modem engineering has defined, with reasonable clearness, the respective fields of these agents, into either of which the other agent cannot hope to enter with any degree of success. The rivalry of the earlier days between these two forms of power transmission has given place to a mutual recognition of one another's merits and cordial cooperation in certain classes of work for which neither alone is fully adapted.
